Wayne Shepard and wife, Rosemary Sanders Shepard (“plaintiffs”) appeal from the trial court’s grant of Rule 12(b)(6) motions to dismiss filed by Wells Fargo Bank Minnesota, N.A. (“Wells Fargo”) and Ocwen Federal Bank, FSB (“Ocwen”) (collectively, “defendants”). We affirm.
I. Background
Plaintiffs obtained a second mortgage loan secured by their residential real property from Chase Mortgage Brokers, Inc. (“Chase”). The closing date for the loan was 25 July 1997. Plaintiffs were charged a loan origination fee by Chase. This fee was deducted from the loan proceeds and “wrapped” into the loan to be repaid over the course of several months. The loan was first assigned to Ocwen and later to Wells Fargo.
Plaintiffs filed this action against defendants on 3 May 2002 alleging the loan origination fee was usurious and illegal. The complaint asserted violations of N.C. Gen. Stat. § 24-1 et seq., N.C. Gen. Stat. § 75-1.1, sought reformation of the loan itself, treble damages, and attorneys’ fees. Defendant Donald T. Ritter was the trustee of the original deed of trust and was joined as a party in the action for the reformation claim.
On 9 January 2004, Wells Fargo moved to dismiss plaintiffs’ complaint under Rule 12(b)(6) of the North Carolina Rules of Civil Procedure. Wells Fargo affirmatively asserted and argued plaintiffs’ claims were precluded by expiration of the applicable statute of limitations. The trial court heard Wells Fargo’s motion and a similar motion to dismiss filed by Ocwen during its 3 May 2004 civil session. *477The trial court granted defendants’ motions to dismiss on 8 July 2004 based on plaintiffs’ failure to file within the expiration of the applicable statute of limitations. Plaintiffs appeal.
II. Issue
The sole issue before this Court is whether the trial court properly determined the statute of limitations for plaintiffs’ claims had expired and dismissed plaintiffs’ complaint.
III. Usury Law
Plaintiffs argue the trial court erred by dismissing their claims under N.C. Gen. Stat. § 24-1 et seq. for expiration of the applicable statute of limitations. We disagree.
A. Standard of Review
In reviewing the trial court’s grant of a Rule 12(b)(6) motion to dismiss, we must determine whether “as a matter of law, the allegations of the complaint, treated as true, are sufficient to state a claim upon which relief can be granted under some legal theory.” Considine v. Compass Grp. USA, Inc., 145 N.C. App. 314, 316-17, 551 S.E.2d 179, 181 (citing Lynn v. Overlook Development, 328 N.C. 689, 692, 403 S.E.2d 469, 471 (1991)), aff'd, 354 N.C. 568, 557 S.E.2d 528 (2001); see also N.C. Gen. Stat. § 1A-1, Rule 12(b)(6) (2003). The trial court’s dismissal is affirmed only if “ ‘it appears beyond doubt that the plaintiff could prove no set of facts in support of his claim which would entitle him to relief.’ ” Meyer v. Walls, 347 N.C. 97, 111-12, 489 S.E.2d 880, 888 (1997) (quoting Dixon v. Stuart, 85 N.C. App. 338, 340, 354 S.E.2d 757, 758 (1987)).
Dismissal of a complaint under Rule 12(b)(6) is proper when one of the following three conditions is satisfied: (1) when the complaint on its face reveals that no law supports plaintiff’s claim; (2) when the complaint on its face reveals the absence of fact sufficient to make a good claim; (3) when some fact disclosed in the complaint necessarily defeats plaintiff’s claim.
Jackson v. Bumgardner, 318 N.C. 172, 175, 347 S.E.2d 743, 745 (1986) (citing Oates v. JAG, Inc., 314 N.C. 276, 278, 333 S.E.2d 222, 224 (1985)).
B. Statute of Limitations
The trial court dismissed plaintiffs’ complaint under Rule 12(b)(6) on the ground it disclosed a defect to defeat plaintiffs’ *478claims. “A statute of limitations defense may properly be asserted in a Rule 12(b)(6) motion to dismiss if it appears on the face of the complaint that such a statute bars the claim.” Horton v. Carolina Medicorp, Inc., 344 N.C. 133, 136, 472 S.E.2d 778, 780 (1996). “Once a defendant raises a statute of limitations defense, the burden of showing that the action was instituted within the prescribed period is on the plaintiff. A plaintiff sustains this burden by showing that the relevant statute of limitations has not expired.” Id. (citations omitted).
Here, defendants asserted the affirmative defense of expiration of the applicable statute of limitations to plaintiffs’ claims. The statute of limitations for a claim under the usury statutes of N.C. Gen. Stat. § 24-1 et seq. is two years. N.C. Gen. Stat. § 1-53(2)-(3) (2003). The issue before us is the date the two year period accrues. “Ordinarily, the period of the statute of limitations begins to run when the plaintiffs right to maintain an action for the wrong alleged accrues. The cause of action accrues when the wrong is complete, even though the injured party did not then know the wrong had been committed.” Davis v. Wrenn, 121 N.C. App. 156, 158-59, 464 S.E.2d 708, 710 (1995) (quotation omitted), cert. denied, 343 N.C. 305, 471 S.E.2d 69 (1996).
Generally, the question of when a cause of action accrues is a factual determination. Spears v. Moore, 145 N.C. App. 706, 708, 551 S.E.2d 483, 485 (2001). However, “where the evidence is clear and shows without conflict that the claimant had both the capacity and opportunity to discover” the underlying issue but failed to do so, “the absence of reasonable diligence is established as a matter of law.” Grubb Properties, Inc. v. Simms Investment Co., 101 N.C. App. 498, 501, 400 S.E.2d 85, 88 (citing Moore v. Casualty Co., 207 N.C. 433, 177 S.E. 406 (1934)), aff'd, 328 N.C. 267, 400 S.E.2d 36 (1991). We review de novo questions of law. In re Appeal of the Greens of Pine Glen Ltd. Part., 356 N.C. 642, 647, 576 S.E.2d 316, 319 (2003). “Under a de novo review, the court considers the matter anew and freely substitutes its own judgment for that of the [trial court].” Id. (citing Mann Media, Inc. v. Randolph Cty. Planning Bd., 356 N.C. 1, 13, 565 S.E.2d 9, 17 (2002)).
The United States District Court for the Middle District of North Carolina addressed this issue in Faircloth v. Nat’l Home Loan Corp., 313 F. Supp. 2d 544 (M.D.N.C. 2003), aff'd, 87 Fed. Appx. 314 (4th Cir. 2004) (unpublished). There, the class action plaintiffs asserted the identical causes of action for violations of North Carolina’s Usury Statutes and Unfair and Deceptive Trade Practices Act as plaintiffs do ' here. Id. at 548. The defendants in Faircloth asserted the plaintiffs’ *479causes of action accrued on the closing date and the plaintiffs’ complaint was filed after expiration of the applicable statutes of limitation. Id. at 552. The court agreed. “[T]he wrong that continues over time, however, is different from a wrong which comes into existence or becomes known only after a passage of time .... [T]he alleged statutory violation, though continuing, is solitary and that a solitary action is distinguishable from wrongs that are perpetrated seriatim.” Id. at 552-53 (citing and quoting Miller v. Pac. Shore Funding, 224 F. Supp. 2d 977 (M.D.Md. 2002), aff’d, 92 Fed. Appx. 93 (2004)). The Miller court concluded:
More than three years before filing his suit, at the closing of the loan, [the plaintiff] had sufficient knowledge of circumstances indicating he might have been harmed. The allegedly illegal fees were itemized on the face of the loan documents he signed on that date. The continued charging, collecting, and receiving of those fees by the lender or its assignees do not continuously renew the accrual of his cause of action.
224 F. Supp. 2d at 990, n. 6.
Citing Miller, the Faircloth court determined, “the running of the statute of limitations for the plaintiffs cause of action began at the loan closing because the alleged wrong was not of a type that could become known only after a passage of time and because the alleged wrong, though continuing, arose from one unitary action.” 313 F. Supp. 2d at 553. The court held the statutes of limitation for both causes of action accrued on the closing date and expired prior to the plaintiffs filing their complaint. Id. at 554.
Although we are not bound by federal case law, we may find their analysis and holdings persuasive. Soderlund v. Kuch, 143 N.C. App. 361, 370, 546 S.E.2d 632, 638 (“With the exception of the United States Supreme Court, federal appellate decisions are not binding upon either the appellate or trial courts of this State.”), disc. rev. denied, 353 N.C. 729, 551 S.E.2d 438 (2001); Huggard v. Wake County Hospital System, 102 N.C. App. 772, 775, 403 S.E.2d 568, 570 (1991) (“As an interpretation of state law by a federal court, this holding is not binding on us; however, we find its analysis persuasive.”), aff’d, 330 N.C. 610, 411 S.E.2d 610 (1992); House v. Hillhaven, Inc., 105 N.C. App. 191, 195, 412 S.E.2d 893, 896 (Federal cases, although not binding on this Court, are instructive and persuasive authority.), disc. rev. denied, 331 N.C. 284, 417 S.E.2d 251 (1992). We hold the Middle District’s analysis and resolution of the issue at bar is correct.
*480Plaintiffs’ claim against defendants arises out of alleged misrepresentations of terms and conditions of the loans, excessive loan origination fees and costs, and inflated expenses. However, all details of the loan, including interest rate, fees, and expenses, were fully disclosed in the loan documents to plaintiffs prior to closing. This shows plaintiffs had “both the capacity and opportunity to discover” their claim, but failed to do so. Grubb Properties, Inc., 101 N.C. App. at 501, 400 S.E.2d at 88. Plaintiffs were on notice of the pertinent terms and conditions of the loan. We further note that N.C. Gen. Stat. § 24-10(g) (2003) states in part, “The fees . . . are fully earned when the loan is made ....” The alleged wrongdoing by defendants accrued and was complete upon the closing of the loan. Plaintiffs’ right to initiate an action accrued. See Davis, 121 N.C. App. at 158-59, 464 S.E.2d at 710 (“Ordinarily, the period of the statute of limitations begins to run when the plaintiff’s right to maintain an action for the wrong alleged accrues. The cause of action accrues when the wrong is complete, even though the injured party did not then know the wrong had been committed.”).
Plaintiffs assert the interest and expenses associated with the loan origination fee should be treated the same as interest based on the underlying loan. Thus, the statute of limitations would accrue on the date of payment, not the date of closing. As authority, they cite our Supreme Court’s decisions in Hollowell v. B. & L. Association, 120 N.C. 286, 26 S.E. 781 (1897) and Swindell v. Federal National Mortgage Assn., 330 N.C. 153, 409 S.E.2d 892 (1991). In Hollowell, the plaintiff borrowed $1,000.00 from the defendant. 120 N.C. at 287, 26 S.E. at 781. The defendant charged plaintiff both interest and “dues” to be paid each month, as required by the loan contract. Id. The plaintiff argued that the combination of the required interest and “dues” were usurious. Id. The defendant asserted the monthly “dues” did not count towards the usury limit. Id. at 288, 26 S.E. at 781-82. The Court held, “whatever is collected over and above 6 per cent, whether called interest or “dues” is, in fact, interest and usurious.” Id. at 287, 26 S.E. at 781. Our review of Hollowell indicates an important distinction from plaintiffs’ complaint. There, the defendant required the plaintiff to pay the “dues” every month during the term of the loan. Id. Here, plaintiffs were free to pay the loan origination fee up front and not to finance it with proceeds from the loan.
In Swindell, the plaintiff “executed an adjustable rate note secured by a deed of trust on a home for $112,500.00” from a mortgage lender. 330 N.C. at 155, 409 S.E.2d at 893. The defendant pur*481chased the note from the mortgage lender. Id. The loan contract included a provision for late payment penalties for untimely payments toward the note. Id. The late payment interest rate exceeded the State’s usury limits and the plaintiffs filed a complaint seeking declaratory relief. Id. at 155-56, 409 S.E.2d at 893-94. The defendant argued the late charge was not usurious under the statutes. Id. at 156, 26 S.E. at 894. The Court held differently, interpreting late fees governed by N.C. Gen. Stat. § 24-10.1 to be interest and subject to the usury laws. Id. at 157-58, 409 S.E.2d at 895. Like Hollowell, we hold a distinction exists between a required late payment fee that may or may not be charged and a loan origination fee that plaintiffs have the option and right to pay up front to avoid accrued interest.
Plaintiffs also argue the two year statute of limitations accrues individually for each date of payment of interest and runs forward. Plaintiffs cite this Court’s decisions in Haanebrink v. Meyer, 47 N.C. App. 646, 267 S.E.2d 598 (1980) and Merrill v. Knox,, 94 N.C. App. 340, 380 S.E.2d 160 (1989). However, our review of Haanebrink and Merritt shows the usurious interest rates at issue were related to the actual promissory notes, not an origination fee. 47 N.C. App. at 650, 267 S.E.2d at 600; 94 N.C. App. at 342, 380 S.E.2d at 162. Here, the purported illegal loan and interest at issue derives from a loan origination fee. Although plaintiffs make periodic payments toward the loan, the fee was paid on the date of closing out of the loan proceeds.
We hold the closing date, 25 July 1997, is the date of accrual of plaintiffs’ claim as a matter of law. Grubb Properties, Inc., 101 N.C. App. at 501, 400 S.E.2d at 88. Plaintiffs were on notice of the origination fees and had all the necessary information prior to and on the date of closing. Chase did not require plaintiffs to finance the loan origination fee. Plaintiffs legally had the option of paying the loan origination fee up front with cash, check, or credit card, rather than financing it with their loan proceeds. Chase “fully earned” the loan origination fee on the closing date, when it was paid in full.
Plaintiffs did not file their complaint until 3 May 2002, more than two years after the closing date and accrual of the cause of action. The statute of limitations elapsed on 25 July 1999. The trial court properly dismissed plaintiffs’ claim under N.C. Gen. Stat. § 24-1 et seq. See Jackson v. Bumgardner, 318 N.C. at 175, 347 S.E.2d at 745 (Atrial court’s grant of a 12(h)(6) motion to dismiss is proper when some fact disclosed in the complaint necessarily defeats plaintiff’s claim.). This assignment of error is overruled.
*482IV. Unfair and Deceptive Trade Practices
Plaintiffs concede their unfair and deceptive trade practices claim derives from their usury claim. Thus, they stipulated should this Court hold the trial court erred in determining the usury claim was time-barred the same would apply to their unfair and deceptive trade practices claim. In light of our holding that plaintiffs’ usury claim was barred by the applicable statute of limitations, plaintiffs’ argument is moot. Plaintiffs stipulate in their brief that their claim under N.C. Gen. Stat. § 75-1.1 is otherwise time-barred under the applicable statute of limitations. In light of our holding on plaintiffs’ usury claim and plaintiffs’ stipulation, we do not reach the issue of whether the trial court properly dismissed plaintiffs’ claim under N.C. Gen. Stat. § 75-1.1. This assignment of error is dismissed.
V. Conclusion
Defendants properly asserted the affirmative defense of expiration of the applicable statute of limitations to plaintiffs’ cause of action for usury under N.C. Gen. Stat. § 24-1 et seq. The accrual date for claims based on loan origination fees fully earned and paid on the closing date is the closing date. Plaintiffs’ stipulation to the correctness of the trial court’s dismissal of their unfair and deceptive trade practices claim renders this argument moot and precludes our review of that issue. The trial court’s order granting defendants’ motions to dismiss is affirmed.
