This is an action of contract to recover the balance due on a negotiable promissory note dated August 17, 1912, for $15,000, payable in two years from date to a third person, and indorsed to the plaintiff. One defence is the statute of limitations. So far as here material, indorsements on the note were, “ $375 — interest on the within note paid to July 8, 1914. $1,744.50 paid on principal on within note. $331.40 interest on within note to Jan. 5, 1915.” None of these were in the handwriting of the defendant. Conceded facts at the trial were that on July 8 or 9, 1914, a payment by the defendant was made on the principal of the note, the amount of which was in dispute. The sum of $375 due as interest for the six months then last past was paid by the defendant at or about the same time, this being shown by the indorsement. Confessedly the note was outlawed in the hands of the plaintiff, an indorsee, unless a payment was made thereon by the defendant within six years before the date of the writ, which was December 24, 1920. The defendant testified on this point that early in July, 1914, he met the plaintiff and her father, that he wanted a partial release of the mortgage securing the note, that the plaintiff’s father insisted upon payment of twenty-five cents per foot on the land to be released and of six months’ interest in advance to January 5, 1915, as a condition of giving the release. His further testimony was, “ Thereupon, I agreed to pay twenty-five cents and the interest in advance, and went out saying I would be back shortly with the money *519for both release and interest. In an hour I returned with a little over $2,900, sufficient to pay for the release, but I told them I could not raise the money for the advance interest. I gave them my word I would pay it within a week, and they took my word. I paid them in two $1,000 bills, one $500 bill, four $100 bills and the rest in small stuff. Within a week I paid plaintiff’s father the six months interest in advance, a little over $300. That was the last money and time I ever paid on that note.”
The plaintiff’s father testified that no such transactions as were testified to by the defendant 'occurred except that he, being at that time the record holder, signed a partial release of the mortgage securing the note. The plaintiff testified that she received on July 8 or 9, 1914, $375 as interest, and $1,744.50 for the release, and that the indorsements of those payments on the note were in her handwriting. The husband of the plaintiff testified, “ I received the last payment on this note. The last indorsement is in my handwriting. I don’t remember where I received it, but I received it somewhere from the defendant.” There was conflict upon other incidental matters between the testimony of the defendant and that of the plaintiff and of her father.
The burden of proof was on the plaintiff to show both a cause of action and the suing out of process within the period of limitations, that is, within six years prior to December 24, 1920. Pond v. Gibson, 5 Allen, 19. Slocum v. Riley, 145 Mass. 370. Currier v. Studley, 159 Mass. 17, 20. The indorsements on the back of the note were not sufficient proof standing alone to take the note out of the statute of limitations. None of them were made by or in the presence of the defendant. G. L. c. 260, § 14.
The testimony of the defendant might have been disbelieved except so far as it constituted admissions against himself. Lindenbaum v. New York, New Haven & Hartford Railroad, 197 Mass. 314. Commonwealth v. Russ, 232 Mass. 58, 70. Disregarding the testimony of the defendant, so far as favorable to himself, the remaining facts, which might have been found, were that interest amounting to $331.40 was paid by the defendant on the note, that this *520amount of interest was due in January, 1915, and that this was the amount of interest on the balance due on the note according to the testimony of the plaintiff and other witnesses and was a larger amount than was due according to the testimony of the defendant. While there is no categorical evidence to the effect that the last instalment of interest actually was paid on the note within six years before the date of the plaintiff’s writ, yet it might have been regarded as common knowledge that interest on mortgage notes is not usually paid in advance or before it is due, and that hence this payment of interest, confessedly made by the defendant in some amount within six months after July 8, 1914, was not made until or about its due date, that is to say, January, 1915, which would be within six years' prior to the suing out of the writ. The instructions to the jury on this point were not open to objection. The verdict of the jury shows that the inference was drawn that the payment of interest was not made very long, if at all, before it was due. It cannot be pronounced unwarranted by the evidence and the inferences reasonably to be drawn therefrom.
The defendant in his answer “ set up payment and also specially averred that ‘ plaintiff agreed with defendant to await his recovery ’ from his illness and financial difficulties ‘ and not to press him in regard to interest or principal on said mortgage, and not to exercise the power of sale contained therein; ’ that, ‘ without giving notice to the defendant that she repudiated said agreement or was going to ignore the same, plaintiff subsequently advertised the mortgaged premises for sale under such power of sale and sold the mortgaged property at mortgagee’s sale to herself at the price of $12,700, without having given the plaintiff any adequate opportunity to turn himself around and protect himself, intending to acquire the title to the mortgaged property at less than its fair market value; ’ that, by the aforesaid conduct, the plaintiff did not act in good faith as defendant’s mortgagee, and that her conduct in the premises had ‘ extinguished the defendant’s liability on said promissory note,’ and constituted in law an ' accord and satisfaction ’ thereof.”
*521The averments of the answer constituted the pleading of an affirmative defence, the burden of proving which rested on the defendant. Wylie v. Marinofsky, 201 Mass. 583, 584. Taylor v. Weingartner, 223 Mass. 243, 248. Hughes v. Williams, 229 Mass. 467, 470.
The plaintiff, in August, 1915, foreclosed the mortgage by which the note was secured, purchasing the property covered by it herself and crediting on the note $12,563 after deducting expenses. With respect to this the “ defendant testified in substance that in the spring of 1915, he was sick and in financial troubles, and, being pressed for payment of the mortgage by the plaintiff, he talked with her on the telephone and told her his conditions; that she told him not to worry about them, that she would wait until he got over his illness and financial troubles, and would not press him for payment or foreclosure, and he believed her; that, subsequently, in August, when he was sick abed, he accidentally learned from one Gould, an attorney, that the mortgage was advertised for foreclosure on the next day, and he sent the attorney to the sale to protest against it.” Gould testified that he went to the sale, protested against it, and that it was continued by the plaintiff’s auctioneer for one week. There was other evidence to the effect that the sale was continued a week. There was evidence, also, that the plaintiff’s father had sold the property to the defendant for $20,000 in 1912.
“ As bearing on the value of said property and to show that the defendant had been damaged by the alleged breach of said agreement to wait, and that the plaintiff, by such foreclosure, got more than the credit allowed in the net price bid at the foreclosure sale, defendant attempted to prove what plaintiff subsequently sold* the property for, contending that he expected to show that it was sold for much in excess of the price so bid at the sale.” This offer of evidence was excluded rightly. Vahey v. Bigelow, 208 Mass. 89, 93. It and all the other evidence in the case was insufficient to show bad faith on the part of the plaintiff in the foreclosure of the mortgage. The note was long overdue. The right to foreclose was complete and indis*522putable. There is nothing to indicate that there was not full compliance with every requirement of the mortgage as to foreclosure, or that there were not numerous bidders at the sale. The promise of the plaintiff to delay foreclosure of the mortgage was without consideration and hence was not binding upon her. Williams v. Sneirson, 225 Mass. 199. Downing v. Brennan, 232 Mass. 535. Barnett v. Rosen, 235 Mass. 244. Rowland v. Hackel, 243 Mass. 160.
The plaintiff was bound to exercise good faith in the exercise of the power of sale. Bon v. Graves, 216 Mass. 440. Stevenson v. Dana, 166 Mass. 163, 170. Mere inadequacy of price obtained at the foreclosure sale falls short of showing bad faith. Learned v. Geer, 139 Mass. 31. O’Brien v. Logan, 236 Mass. 507, 511. Vahey v. Bigelow, 208 Mass. 89, 93. All the evidence in its aspect most favorable to the defendant fails to sustain any of the affirmative defences set up in his answer. Radley v. Shackford, 226 Mass. 435. Manning v. Liberty Trust Co. 234 Mass. 544. Stone v. Haskell, 212 Mass. 283.
There was no error of law in the instructions given to the jury or in the denial of the requests for rulings.
The exception touching the expenses of foreclosure was waived.
