OPINION OF THE COURT
WEIS, Circuit Judge.Pennsylvania statutes require that notice be given to a mortgagor before foreclosure proceedings may begin. The question on this appeal is whether a federal agency must comply with those statutes before foreclosing on a mortgage acquired in the course of a federal loan program. No-third party commercial interests are affected, and so we find no compelling reason to incorporate state law as the rule of decision. Accordingly, we will vacate a district court order directing the agency to comply with the state statutes.
In 1981, defendant Doris Spears (now Doris Rivera)1 and her husband Marcus Spears (now deceased) purchased property located in Alburtis, Pennsylvania. The purchase was financed by a mortgage in the amount of $43,500 given by the Spears to the Farmers Home Administration (FmHA). Because of their modest income, the Spears received an “interest credit” subsidy from the FmHA, reducing the monthly payments from $487 to $130. Payments were made until June 1982, but none has been received since that time.
In July 1982, as the result of a marital dispute, the couple separated. Mr. Spears moved to New York and Ms. Rivera moved to Puerto Rico, expecting, she said, to be gone for three or four months. While in Puerto Rico, Ms. Rivera underwent treatment for various physical ailments and severe depression. She secured a consensual divorce in December 1982.
On October 14, 1982, the FmHA wrote to Ms. Rivera in Puerto Rico, stating that “[i]t has come to our attention that you have vacated your property. This is a violation of your mortgage agreement_ Your interest credit has also been cancelled and payments increased....” She was advised that she could either sell the property or refinance the mortgage and pay the government in full. A corresponding communication was mailed to Mr. Spears. Letters to the same effect were also sent to *286both parties on January 18, 1983. In July 1983 Ms. Rivera left Puerto Rico and moved to her daughter’s residence in Allentown, Pennsylvania.
In a letter dated March 16, 1984, the FmHA informed Ms. Rivera that default on the mortgage had occurred because of failures to make payments and to occupy the premises. The agency stated its intent to accelerate the loan and to begin foreclosure proceedings within thirty days. Once again Ms. Rivera was told that she could cure the default by making specified payments, transferring the property to another person in accordance with agency regulations, or refinancing the mortgage. The letter also gave notice of the right to an administrative hearing if she submitted a request within thirty days. The record contains no response by Ms. Rivera to any of these letters. Ms. Rivera moved back into the house in November 1985, and she has lived there since that time without paying any installment on the mortgage.
Foreclosure proceedings in the district court began in the summer of 1985. After disposing of some preliminary matters, the district court, with the consent of the parties, remanded the case to the FmHA for administrative determinations. Following a hearing and an appeal to the state director, the FmHA determined that the property had been abandoned in July 1982 and had remained so until December 1985. Consequently, the agency decided to continue with foreclosure.
The case then returned to the district court. On review, the court found that subtantial evidence supported the administrative decision on abandonment and that the agency, therefore, had properly denied relief to Ms. Rivera. The district judge, however, upheld the defendant’s contention that the FmHA was required to comply with two Pennsylvania statutes—Act 6 of 1974, 41 Pa.Stat.Ann. § 401-08 (Purdon 1988), and Act 91 of 1983, 35 Pa.Stat.Ann. § 1680.401c (Purdon 1988). These statutes direct that a mortgagor be given written notice of a mortgagee’s intention to begin foreclosure proceedings at least thirty days in advance. In addition, the mortgagor must be provided a list' of consumer credit counseling agencies and be notified of the right to apply for financial assistance from the state’s Homeowner Emergency Mortgage Program.
The district court observed that these statutes neither afforded additional substantive benefits to FmHA mortgagors nor imposed a substantial administrative burden on the government. State law did not interfere with, or frustrate the objectives of, the federal program, and there was no need for uniform administration on a national basis. Relying on United States v. Kimbell Foods, Inc., 440 U.S. 715, 99 S.Ct. 1448, 59 L.Ed.2d 711 (1979), the court again remanded to the FmHA, directing it to “comply with the provisions of Act 6 and Act 91, after which the [government’s] motion for summary judgment may be renewed.” Both parties’ motions for summary judgment were denied in the same order.
On appeal Ms. Rivera contends that the district judge erred in finding that the FmHA had produced substantial evidence to justify its abrogation of the financing arrangements. In its cross-appeal, the FmHA asserts that it is not required to comply with the state statutes which restrict a mortgagee’s remedies against its mortgagor.
I.
A.
Ms. Rivera cites 28 U.S.C. § 1291 as the basis for appellate jurisdiction because, she contends, her appeal is taken from a final order. Although the FmHA has not contested that statement, it is clear that the order lacks finality in the traditional sense.
The summary judgment motions of both Ms. Rivera and the FmHA were denied, and the case was remanded to the agency. The denial of a summary judgment motion is not a final order, Boeing Co. v. International Union, United Auto., Aerospace & Agric. Implement Workers of America, 370 F.2d 969, 970 (3d Cir.1967).
Moreover, an order remanding a matter to an administrative agency is no *287more than an interlocutory step in adjudicative proceedings and is generally not ap-pealable. United Steelworkers of America, Local 1913 v. Union R.R., 648 F.2d 905, 909 (3d Cir.1981); Marshall v. Celebrezze, 351 F.2d 467, 468 (3d Cir.1965). An exception exists, however, to the nonap-pealability of such remand orders. In AJA Assoc. v. Army Corps of Engineers, 817 F.2d 1070, 1073 (3d Cir.1987), we stated that proposition as follows: “when a district court finally resolves an important legal issue in reviewing an administrative agency action and denial of appellate review before remand to the agency would foreclose appellate review as a practical matter, the remand order is immediately appealable.” See also Horizons Int’l, Inc. v. Baldrige, 811 F.2d 154 (3d Cir.1987); Union R.R., 648 F.2d 905.
The remand order here falls within the special exception articulated in our cases. If the FmHA complies with the district court’s order—giving the requisite state notification and then proceeding to foreclosure—the issue will become moot. On the other hand, if the agency declines to follow Pennsylvania law, the district court’s directive will prevent the foreclosure action from proceeding, and the case will remain in limbo.
Moreover, the FmHA raises an issue that is significant in the day-to-day operation of the agency and has spawned conflicting district court decisions within this circuit. See, e.g., United States v. Black, 622 F.Supp. 669 (W.D.Pa.1985); United States v. Royer, 683 F.Supp. 484 (M.D.Pa.1986), aff'd, 815 F.2d 696 (3d Cir.1987). Finally, the question before us is purely one of law; the remand to the agency is not for the purpose of securing additional factual information. In these circumstances, we conclude that the district court’s order directing the FmHA to comply with Pennsylvania Acts 6 and 91 is appealable.
B.
Ms. Rivera’s appeal of the denial of her motion for summary judgment, however, presents separate jurisdictional problems. As noted above, such orders usually are not appealable, but here factors of reality and practicality must be evaluated.
We have the benefit of the district court’s ruling that substantial evidence supports the agency’s decision to deny Ms. Rivera’s request to continue the mortgage in force. Our reading of the district court opinion leaves no doubt that, if the FmHA complies with Acts 6 and 91, summary judgment will be entered in its favor. A remand to the district court at this juncture would result in yet another appeal to this court raising precisely the same contentions now before us. We would then be encouraging, rather than discouraging, piecemeal appeals were we to decline review of Ms. Rivera’s contentions now.
We recognize the strictures on appellate jurisdiction, but are mindful of a fairly well-defined, but narrow exception. In San Filippo v. United States Trust Co., 737 F.2d 246, 254-55 (2d Cir.1984), cert. denied, 470 U.S. 1035, 105 S.Ct. 1408, 84 L.Ed.2d 797 (1985), the court explained the doctrine of pendent appellate jurisdiction. “[0]nce we have taken jurisdiction over one issue in a ease, we may, in our discretion, consider otherwise nonappealable issues in the case as well, where there is sufficient overlap in the facts relevant to [the appeal-able and nonappealable] issues to warrant our exercising plenary authority over [the] appeal.” Id. at 255. See also Barrett v. United States, 798 F.2d 565, 571 (2d Cir.1986); Consolidation Coal Co. v. Local 1702, United Mineworkers of America, 683 F.2d 827, 831 (4th Cir.1982); Intermedies Infusaid, Inc. v. Regents of University of Minnesota, 804 F.2d 129, 134 (Fed.Cir.1986).
This exception, it must be emphasized, is an exercise of discretion by a Court of Appeals and should be used sparingly. Casual application might lead to abuse. For example, as a device to obtain review of a matter not otherwise within our jurisdiction, a litigant might bring us inconsequential issues that normally would not be appealed. See 16 C. Wright, A. Miller & E. Cooper, & E. Gressman, Federal Practice and Procedure § 3937 (1976 & 1987 Supp.). That danger, however, clearly is not posed *288here where the cross-appeal gives us jurisdiction.
Although this Court has not expressly acknowledged that review of collateral matters may fall within our pendent jurisdiction, we have in fact ruled on such questions. In Horizons Int’l, the Court considered in the appeal an issue collateral to the administrative order. See 811 F.2d at 170. Similarly, in AJA Associates, where we had taken jurisdiction over a remand order, the panel remanded several contentions on the merits for “reasons of institutional integrity”—in short, to allow the district court to pass on the factual matters in the first instance. The panel gave a strong indication that it was not impressed with the appellant’s argument on the merits, suggesting that “AJA’s remaining arguments may also be meritless and resolution of the case on a motion for summary judgment may be appropriate.” AJA Assoc., 817 F.2d at 1074.
The present situation may be distinguished from that in Kershner v. Mazurkiewicz, 670 F.2d 440 (3d Cir.1982), where we limited the scope of an appeal under 28 U.S.C. § 1292(a) to issues intertwined with the preliminary injunction itself. There, we construed a statute that purported to grant only a limited exception “to the long-established policy against piecemeal appeals.” Id. at 446-47.
The differences between Kershner and the one at hand are pertinent. In the preliminary injunction context, one expects that the case will be remanded to the district court to resolve the application for a permanent injunction. Thus, opportunity for appellate review of all issues will be provided ultimately. In addition, as we noted in Kershner, premature appellate review of an interlocutory order could disrupt the functioning of the district court by taking matters out of the judge’s hands before the occasion for a ruling arose.
Neither of those circumstances is present here. Instead, the situation is more akin to that in Johnson v. Alldredge, 488 F.2d 820 (3d Cir.1973), cert. denied, 419 U.S. 882, 95 S.Ct. 148, 42 L.Ed.2d 122 (1974), where on a section 1292(b) appeal we considered issues beyond those subsumed in the question of law certified to us.
To summarize, Ms. Rivera appeals from a matter on which the district court has ruled. The nature of the litigation is such that, upon compliance with our mandate, the district court has already indicated that it will enter summary judgment without further ado; Ms. Rivera will again appeal raising precisely the same issues now before us. Finally, it seems unlikely that any other issues will be appealed because, when the matters presently before us are resolved, the foreclosure action will proceed pro forma. Phrased differently, resolution of the issues at this point ends the battle, and little will remain except to tie up the loose ends. In these circumstances, considerations of judicial economy, the litigant’s interests, and practicality demand that we exercise jurisdiction over the Rivera appeal.
II.
The Pennsylvania statutes which the district court directed the FmHA to observe are known as Acts 6 and 91. Act 6 requires thirty days notice before accelerating the maturity of a residential mortgage or commencing foreclosure proceedings. Parenthetically we note that the notice given by the FmHA here appears to cover substantially the items listed in the state statute. Furthermore, Act 6 provides that the notice “shall not be required where the residential mortgage debtorf] has abandoned ... the property.” 41 Pa.Stat.Ann. § 403(d) (Purdon Supp.1988). As a consequence, it is questionable whether notice was mandated by this Act in any event. Act 91 demands notification to the mortgagor and grants time to apply 'to a state agency for financial assistance before foreclosure may proceed.2
The FmHA loan to the Spears and the execution of a mortgage as collateral for *289the debt is a contractual arrangement subject to federal law. Clearfield Trust Co. v. United States, 318 U.S. 363, 63 S.Ct. 573, 87 L.Ed. 838 (1943). Although a transaction is governed by federal law, the rule of decision in some circumstances is derived from incorporation of relevant state law. Kimbell Foods, 440 U.S. 715, 99 S.Ct. 1448, 59 L.Ed.2d 711; United States v. Walter Dunlap & Sons, Inc., 800 F.2d 1232 (3d Cir.1986). However, before deciding whether, as a matter of federal law, state law should supply the rule of decision, we first examine the terms of the contract to determine if the agency had agreed to comply with state procedures.
Condition 17 of the mortgage provides that “should default occur “the Government, at its option, with or without notice, may: ... declare the entire amount unpaid under the note ... due and payable ... [or] foreclose this instrument as provided herein or by law....”
Paragraph 21 reads, “[t]his instrument shall be subject to the present regulations of the Farmers Home Administration, and to its future regulations not inconsistent with express provisions hereof.”
In paragraph 23, the borrower agrees that upon default “the Government may foreclose this instrument as authorized or permitted by the laws then existing of the jurisdiction where the property is situated and of the United States of America, on terms and conditions satisfactory to the Government, including but not limited to foreclosure by (a) statutory power of sale, or (b) advertisement and sale of the property at public auction to the highest bidder in one or more parcels at the Government’s option and at the time and place and in the manner and after such notice and on terms required by statute or determined by the Government if not contrary to statute.”
The district court pointed to an FmHA regulation, 7 C.F.R. § 1955.15 (1986), setting out the forms to be used in giving notice of acceleration of accounts. The regulation stated that “[a] State Supplement may General Counsel] advises different or additional language or format is required to comply with State laws or if notice and mailing instructions are different from that outlined in this paragraph.”3 Id. § 1995.15(d)(2).
A fair reading of the mortgage documents reveals that the FmHA “may” utilize state foreclosure procedures. Significantly, the contractual language does not state that the agency “must” or “will” do so. Paragraph 17, as noted above, provides that the government “may” foreclose “as provided herein or by law.” The mortgage documents permit the FmHA to proceed in foreclosure proceedings either in state court or, as here, in a federal forum. In sum, no contractual clause binds the government to utilize state law in foreclosure.
Having determined that the choice of law is not dictated by contract terms, we must shift our analysis to the applicable rule of decision. Whether to adopt state law or to fashion a uniform federal rule rests on judicial policy drawn from the nature of the specific governmental interest at stake and the effect of applying state law. The court must ascertain if the federal program, by its nature, demands a single standard nationwide, whether application of state law would frustrate specific objectives of the federal program, and the extent to which application of a federal rule would disrupt commercial relationships predicated on state law. Kimbell Foods, 440 U.S. at 728-29, 99 S.Ct. at 1458-59.
In both Kimbell Foods and Walter Dunlap, the aggrieved parties were not participants in the federal program. They would have been prejudiced by a federal rule preempting the state system of lien priorities of general applicability — statutes “on which private creditors base their daily commercial transactions.” Kimbell Foods, 440 U.S. at 729, 99 S.Ct. at 1459. Noting that businesses look to state commercial law in evaluating risks of financial transac*290tions, the Court observed that “[c]reditors who justifiably rely on state law to obtain superior liens would have their expectations thwarted whenever a federal contractual security interest suddenly appeared and took precedence.” Id. at 739, 99 S.Ct. at 1464.
In contrast, when the controversy does not affect third parties but embroils only the United States and a debtor, the factors that favor applying state law are considerably weakened if not removed entirely from consideration. This result is illustrated in West Virginia v. United States, 479 U.S. 305, 107 S.Ct. 702, 93 L.Ed.2d 639 (1987), where the federal government sued a state on an indebtedness. The issue before the Supreme Court was whether the United States was entitled to prejudgment interest. The Court held that federal law governed the payment of interest due for delayed payment of a contractual obligation. “While there are instances in which state law may be adopted as the federal rule of decision ... this case presents no compelling reason for doing so.... [Application of a federal rule would not ‘disrupt commercial relationships predicated on state law’ ... since state law would not of its own force govern contracts between a state and the Federal Government.” West Virginia, 479 U.S. at 309, 107 S.Ct. at 705.
In the appeal here, it is significant that the mortgagees seek to enforce state procedural, rather than substantive, law. The FmHA regulations provide adequate notice and opportunity for hearing, and, consequently, due process considerations do not dictate the choice. See 42 U.S.C. §§ 1475, 1480(g), (k) (1982 & Supp. IV 1986); 7 C.F.R. § 1955.15 (1986). Cf. Johnson v. United States Dep’t of Agric., 734 F.2d 774 (11th Cir.1984).
The record establishes that a letter dated January 18, 1983 was sent by the FmHA to the Spears notifying them that because they had violated the terms of their mortgage, failure to take curative action within twenty days would result in foreclosure. The agency, however, did not begin foreclosure at that time.
More than one year later, by letter dated March 16, 1984, the FmHA again called attention to the default and advised the Spears of the agency’s intention to accelerate the loan and foreclose on the mortgage. Proceedings were to be instituted within thirty days unless the delinquency was corrected. The letter also explained that the marshal would sell the property in approximately sixty days, but that the debtors could contact the FmHA within thirty days if they wished to schedule a hearing. Once again, the FmHA did not act as promptly as it had warned.
Foreclosure was not begun until 1985, and only after service of a complaint did Ms. Rivera request a hearing. The record demonstrates that she received notice on more than one occasion and had an ample opportunity for a hearing. Due process was observed, and there was no need to resort to the state notification statutes.
Other factors discussed in Kimbell Foods and West Virginia lead us to conclude that state law should not supply the rule of decision here. It is true that the contractual arrangements giving the FmHA an option to utilize state procedures conclusively demonstrate that no need for national uniformity is present. Nor can we say that application of state law would always frustrate the aims of the federal program. The fact that the FmHA has the contractual alternative to employ state procedures suggests that their use may be compatible with the federal scheme, at least in some circumstances. Efficient operation of the federal program conceivably could be improved through the FmHA’s decision to utilize state law. For example, although not authorized by Pennsylvania law, sale by the mortgagee in the event of default without the delay and expense of foreclosure is permissible in some states. See Johnson, 734 F.2d at 777.
In Kimbell Foods and Walter Dunlap the critical factor counselling application of state law was the threat to commercial relationships founded on expectations of third parties relying on existing state statutes. In those cases, lien priorities had been established by an intricate network of *291state laws regulating commercial activities in which federal programs were intruding. Federal interests would not suffer, and private businesses would benefit, by accommodating state law. On balance, therefore, it was preferable in both instances to utilize that law as the rule of decision.
Those considerations do not drive the choice here because third party interests are not affected, nor are private business practices threatened or impaired. A state interest in ensuring clear title to real estate is not at stake because the notification requirements at issue do not affect rec-ordation of deeds after a federal foreclosure. A purchase of property at FmHA foreclosure in federal court does not create a cloud on the title.
From the standpoint of mortgagors in general, no overriding benefit flows from insistence on state procedures. FmHA regulations prescribe notification substantially equivalent to that mandated by state law. Indeed, in operation the FmHA administrative regulations and procedures appear to offer mortgagors greater protection than the state statutes. The moratorium provisions of the federal program and the allowance for so-called “interest credit subsidies” do not appear any less favorable than the state refinancing scheme.
Ms. Rivera’s counsel’s thorough familiarity with the state program illustrates the shortcoming of a rote requirement of notification about the state program. Ms. Rivera has been represented by Neighborhood Legal Services since 1985, but has never applied for participation in the state program. One may assume that her inaction stems from a likelihood of ineligibility. In an individual case, notification of that which is already known — and which would be of no utility in any event — is not a circumstance which would justify an exception to general provisions of law. Adherence to non-productive procedures that only result in additional expense and delay fails to support grafting state procedures on to a federal program.
Because no commercial interests or third parties are affected by the utilization of federal procedures, the rationale of the Kimbell-Dunlap analysis is not controlling. As in West Virginia, “this case presents no compelling reason for [adoption of state law].” West Virginia, 479 U.S. at 309, 107 S.Ct. at 705. Accordingly, the FmHA should be permitted to carry out its task of servicing mortgages under the procedures it selects.
In summary, we hold that the FmHA need not comply with Acts 6 and 91 whenever it chooses to utilize the federal court to foreclose on a mortgage in Pennsylvania.
III.
Neighborhood Legal Services represented Ms. Rivera in the proceedings before an FmHA hearing officer. There she asserted her eligibility for a moratorium on past payments and a continuation of the interest credit. From an adverse decision by the hearing officer she appealed to the state director, who affirmed the decision.
FmHA regulations require that a borrower must “personally occupy the dwelling” to receive “interest credit.” 7 C.F.R. § 1944.34(f) (1986). In addition, to secure a moratorium during which scheduled payments are deferred, “[t]he borrower must occupy the dwelling.” 7 C.F.R. § 1951.313(b)(2) (1986). The district court assumed that no violation would occur if the homeowner took an extended vacation for three or four months or was hospitalized for a lengthy period. Nevertheless, the court found substantial evidence to support the agency finding that the Spears had abandoned the premises in July 1982 with no intent to return.
Ms. Rivera conceded, according to the district court, that Mr. Spears’ departure was permanent, but she asserted that her intention was to stay away only for several months. Nonetheless, she did not respond to any of the FmHA’s notifications in 1983 or 1984 other than to express a willingness to reconvey the premises to the government. She did not make any payments which would indicate continued interest in the property; nor did she take any steps for maintenance, such as arranging to heat *292the house in the years after her departure. In Puerto Rico she lived in a home titled in her name and that of her former husband, a circumstance which is consistent with an intention to remain there.
Ms. Rivera asserts that she contacted the FmHA in July or September 1983 and in January 1984. The record contains a notation by an FmHA employee of a telephone conversation in January 1984. At that time Ms. Rivera said she was contemplating moving back into the house, but stated she could not pay the debt, which had grown to more than $50,000. She agreed that it would be better to reconvey the property to the government and proposed to visit the FmHA office whenever requested to sign the papers.
Our standard of review, as well as that of the district court, is limited. If the record contains substantial evidence to uphold the agency’s factual finding, we may not disturb it, even were we inclined to find otherwise on a de novo hearing. See Monsour Med. Center v. Heckler, 806 F.2d 1185, 1190-91 (3d Cir.), cert. denied, — U.S. -, 107 S.Ct. 2481, 96 L.Ed.2d 373 (1987). In light of Ms. Rivera’s expressed willingness on two occasions to convey the property to the government, her failure to arrange for any payments, and her absence for more than a year before making inquiry about returning, we cannot say that the agency’s determination of abandonment lacks substantial evidence.
It follows that, pursuant to its review of the administrative record, the district court should have granted summary judgment for the government because the mortgagors had violated the terms of the contract by abandoning the premises and not making payments.
Accordingly, the order of the district court will be vacated insofar as it required compliance with Pennsylvania Acts 6 and 91. The case will be remanded to the district court for entry of summary judgment in favor of the United States.
. After her divorce, defendant resumed her family name, Rivera. She will be referred to as Ms. Rivera in the course of the opinion.
. In its brief, the government asserts that the state agency will not process applications by federal debtors. If so, Ms. Rivera seemingly would not be eligible for assistance under the state act.
. This refers to paragraph 23. That provision arguably might require the FmHA, if it used state procedures, to comply with such prerequisites as Acts 6 and 91. The crucial fact here, however, is that the FmHA used federal, not state, procedures.
