*118OPINION
By the Court,
Thompson, J.:This appeal concerns the remedy open on default to the holder of promissory notes secured by second deeds of trust. Involved is the interplay of two statutes: the “one-action rule” announced in NRS 40.430 pertaining to the enforcement of a right secured by mortgage on real estate, and NRS 31.010 which allows ancillary attachment in an action upon a note when the security has become valueless, or of insufficient value.
United Mortgage, the payee and holder of 27 promissory notes made by McMillan, and the beneficiary of 27 second trust deeds given as security therefor, commenced a district court action against McMillan, and attached certain of his assets. Each note was for $1,950 (total, $52,650). The 27 second trust deeds were junior to a first deed of trust which had been given by McMillan, as trustor, to Nevada Savings & Loan Association, beneficiary, to secure a $906,000 debt. Inter alia, the complaint alleged, on information and belief, that McMillan had defaulted on his obligation for which the first deed of trust was security, and that “foreclosure proceedings” had been commenced thereon.1 The affidavit of attachment asserted that the payment of the debt of $52,650 was secured by a mortgage, lien or *119pledge, “but that said mortgage, lien, or pledge has become valueless.” Pursuant to NRS 31.200 (la) McMillan moved to discharge the attachment. His motion was denied and this appeal followed.
Here it is not suggested that the notes or the trust deeds grant a right to sue before exhausting the security. Nor did United Mortgage, before starting this suit, expressly or impliedly waive its security. The early case of Hyman v. Kelly, 1 Nev. 179 (1865), hints that one may abandon the security and sue for the collection of the debt. Instead, United Mortgage wishes to pursue alternative courses simultaneously, and we must decide whether this is permissible.
1. In the absence of a preclusive statute, two remedies are open on default to the holder of a secured promissory note. The debt may be enforced by a suit on the note, or by a sale of the land. At common law the creditor could pursue either remedy, or both at once. Bank of Italy v. Bentley, 217 Cal. 644, 20 P.2d 940 (1933). McMillan here contends that NRS 40.4302 is such a preclusive statute and forces the creditor to first exhaust the security or show that it is valueless. Therefore, he suggests that this action upon the promissory *120notes was premature as the security had not been exhausted when suit was commenced, and until that is done a court cannot know whether the security is valueless, or of insufficient value to secure the debt. On the other hand, United Mortgage suggests that the “one-action rule” does not preclude suit on the note when the security for the debt has become valueless, or of insufficient value; to rule otherwise would effectively nullify the intendment of NRS 81.010 allowing ancillary attachment in these circumstances.3 We turn to resolve these divergent views.
2. We must first decide whether a trust deed falls within NRS 40.480. The statute uses the term “mortgage.” A trust deed is not mentioned. Also, it refers to an “action” for the recovery of a debt, and a “judgment” in that action. Thus, it is argued, that as a trust deed is technically not a mortgage, and is “foreclosed” by sale at public auction (NRS eh. 107) rather than by court action, the statute cannot apply.4 The argument is not without persuasion. Yet California, from whom our statute was borrowed, holds squarely that a trust deed is within the statutory “one-action rule” relating to mortgages. In the leading case, Bank of Italy v. Bentley, supra, the court wrote: “Fundamentally, it cannot be doubted that in both situations the security for an *121indebtedness is the important and essential thing in the whole transaction. The economic function of the two instruments would seem to be identical. Where there is one and the same object to be accomplished, important rights and duties of the parties should not be made to depend on the more or less accidental form of the security.” That court went on to state that in either event (whether a mortgage or a trust deed) there is an implied understanding between the parties that the land shall constitute the primary fund to secure the debt. As a practical matter there is no substantial dissimilarity between a mortgage with a power of sale and a deed of trust, except for the statutory right of redemption. Sims v. Grubb, 75 Nev. 178, 336 P.2d 759 (1959). We therefore agree with California, and hold that a trust deed is within the intendment of NRS 40.430.
3. Having determined that a trust deed falls within the intendment of the “one-action rule,” we must next consider the province of NRS 31.010(1) allowing an ancillary attachment when the security has become valueless or of insufficient value. California tells us that part of the attachment statute “refers to a case where the security has changed in the value it had when originally taken, and has so depreciated as to become of no value.” Barbieri v. Ramelli, 84 Cal. 154, 23 P. 1086 (1890). There is no suggestion in this case that there has been a change in the value of the security between the date it was given and the default of McMillan. We think the creditor’s conclusory affidavit to be simply an expression of fear that a sale will not bring enough to satisfy McMillan’s obligations. In any event, the creditor’s opinion of value may not be substituted for the mode of determining that fact. Security First National Bank of Los Angeles v. Chapman, 31 Cal.App.2d 182, 87 P.2d 724 (1939). That mode is first to exhaust the security by sale pursuant to the trust deed. Barbieri v. Ramelli, supra; Hill v. Grigsby, 32 Cal. 55 (1867), where on appeal the court affirmed an order discharging an attachment; Page v. Latham, 63 Cal. 75 (1883), where the appellate court reversed an order refusing *122to discharge an attachment; Giandeini v. Ramirez, 11 Cal.App.2d 469, 54 P.2d 91 (1936), reversing an order refusing to discharge an attachment; Mason v. Jansen, 45 Idaho 354, 263 P. 484 (1927). Dictum of the early Nevada case of Weil v. Howard, 4 Nev. 384 (1868) is in accord. Once the security has been sold and the debt not satisfied, an action on the note with ancillary attachment is permissible. Sims v. Grubb, supra. (Action on the debt, no discussion re attachment.) We reject any expressions in Vande Veegaete v. Vande Veegaete, 75 Mont. 52, 243 P. 1082 (1925), and Edminster v. Van Eaton, 57 Idaho 115, 63 P.2d 154 (1936), which are inconsistent with our views.
In ruling that the holder of a note, secured by a trust deed, must first exhaust the security before an action on the note and ancillary attachment is permissible, we are aware that exceptions exist. Sale of the security is the primary remedy. However, the attachment statute may be utilized if the security, without fault of the mortgagee or beneficiary, has become valueless, as where the security has been destroyed by fire and other similar situations. See Note, 25 Cal.L.Rev. 469 (1937) ; Annot., 108 A.L.R. 397.
For the reasons expressed, the order below refusing to discharge the attachment is reversed.
Badt, J., concurs.For convenience, we, too, will use the mortgage term “foreclosure,” though perhaps not precisely accurate as applied to a trustee’s sale under a trust deed.
NRS 40.430 reads: “There shall be but one action for the recovery of any debt, or for the enforcement of any right secured by mortgage or lien upon real estate, or personal property, which action shall be in accordance with the provisions of this section, and NRS 40.440 and 40.450. In such action, the judgment shall be rendered for the amount found due the plaintiff, and the court shall have power, by its decree or judgment, to direct a sale of the encumbered property, or such part thereof as shall be necessary, and apply the proceeds of the sale to the payment of the costs and expenses of the sale, the costs of the suit, and the amount due to the plaintiff. If the land mortgaged consists of a single parcel, or two or more contiguous parcels, situated in two or more counties, the court may, in its judgment, direct the whole thereof to be sold in one of such counties by the sheriff, and upon such proceedings, and with like effect, as if the whole of the property were situated in that county. If it shall appear from the sheriff’s return that there is a deficiency of such proceeds and balance still due to the plaintiff, the judgment shall then be docketed for such balance against the defendant or defendants personally liable for the debts, and shall, from the time of such docketing, be a lien upon the real estate of the judgment debtor, and an execution may thereupon be issued by the clerk of the court, in like manner and form as upon other judgments, to collect such balance or deficiency from the property of the judgment debtor.”
NRS 31.010, in pertinent part, reads: “The plaintiff at the time of issuing the summons, or at any time afterwards, may have the property of the defendant attached as security for the satisfaction of any judgment that may he recovered, unless the defendant gives security to pay such judgment, as hereinafter provided, in the following cases: (1) In an action upon a judgment or upon a contract, express or implied, for the direct payment of money, which is not secured by mortgage, lien or pledge upon real or personal property situated or being in this state; or if originally so secured, when such security has, without any act of the plaintiff or the person to whom the security was given, become valueless or insufficient in value to secure the sum due the plaintiff, in which case the attachment shall issue only for the unsecured portion of the amount due the plaintiff, or excess of the amount due the plaintiff above the value of the security as the same has become so insufficient.”
