In this Texas law diversity case, defendants-appellants Horst R. Reetz and Kathleen K. Reetz appeal the district court’s summary judgment awarding plaintiff-ap-pellee Savers Federal Savings & Loan Association (Savers) recovery against appellants on their written guaranty of a promissory note (the Note) payable to Savers and executed by the Horst R. Reetz Trust (the Trust), a Texas general partnership of which appellants were the only partners. We affirm.
Facts and Proceedings Below
On August 27, 1984, the Trust executed the Note, which was in the principal amount of $6,300,000, payable to Savers. Appellants individually executed a personal guaranty of payment of the Note. The Note was secured by two deeds of trust, each covering a separate parcel of real property in Dallas County, Texas. One deed of trust, executed by the Trust, cover *1499 ed property knоwn as the Richardson Tech Center; the other deed of trust, executed by appellant Horst R. Reetz, covered what is referred to as the East Collins Road property. The Note was payable in monthly installments due on the first day of each month, the installments being of interest only for an initial period and thereafter of principal and interest. The Note also authorized acceleration of maturity in the event of default in any payment. 1 On November 24, 1986, Savers gave written notice to appellants that “[t]he note is in default for the non-payments of the August through November, 1986 installments of interest.” On January 28, 1987, Savers gave written notice that the Note had been accelerated because of the Trust’s failure to pay any of the interest installments due August 1, 1986 through January 1, 1987. Sometime after January 1987, the Trust petitioned for relief under Chapter 11 of the Bankruptcy Code.
Thеreafter, on April 22, 1987, Savers filed this suit against appellants on their guaranty for the sum of $5,906,569.29, the then outstanding principal balance of the Note, plus interest, reasonable attorneys’ fees, and collection costs. The complaint alleges the defaults in the Note payments, the giving of notice thereof, and of the acceleration of the Note’s maturity as above stated.
Thereafter, on May 20, 1987, appellants, through counsel, filed their answer. The answer denied none of the allegations of the complaint, expressly admitted certain of the allegations, and as to the others merely stated that appellants were “unable to admit or deny.” 2 No affirmative defenses or similar matters were alleged. This answer was never amended, nor, until after final judgment, was it ever sought to be amended. Appellants filed no motions under Fed.R.Civ.P. 12. Although the answеr prayed that Savers take nothing by its suit, nothing in the answer suggests any legal or factual basis for this prayer. On July 6, 1987, Savers filed its motion for summary judgment, with supporting brief and affidavits and sworn copies of the Note and the guaranty thereof executed by appellants. On July 24, 1987, appellants filed their response to the motion for summary judgment with supporting affidavit of appellant Horst Reetz. The response alleged the Trust’s pending bankruptcy proceeding and requested that “this matter be abated until after October 1, 1987 to determine whether or not a plan of reorganization can be instituted and confirmed in the bankruptcy.” Further, Horst Reetz’s affidavit stated: “[I]t was my understanding that the guaranty was to be limited to the extend [sic] of $750,000 liability,” and this allegation is repeated, as to both appellants, in their response. 3 No other legal or factual reasons for denying Savers’ summary judgment motion аre asserted in appellants’ response or Horst Reetz’s supporting affidavit. On July 28, 1987, the district court deferred decision on the motion for summary judgment “until October 1. 1987 to determine whether a reorganization plan can be confirmed and implemented in the [Trust’s] bankruptcy.”
During the pendency of the bankruptcy proceedings, the bankruptcy court granted Savers relief from the automatic stay imposed by section 362 of the Bankruptcy Code, and the substitute trustee in the deed of trust on the Richardson Tech Center *1500 posted that property to be nonjudicially foreclosed under the deed of trust on August 4, 1987. The property was sold to Savers for $3,000,000 at the foreclosure sale on that date, with the Note being then credited in that amount, but Savers and the substitute trustee later rescinded the sale because it was discovered that “there might have been deficiencies” in giving notice of the sale, and the property was posted for a second sale to be conducted on September 1, 1987. Savers was again the successful bidder for $3,000,000 at the September 1,1987 sale. On November 3,1987, the substitute trustee in the deed of trust on the East Collins Road property, after notice, sold that property at nonjudicial foreclosure sale to Savers for $1,000,000, which was then credited on the Note.
The bankruptcy court dismissed the Trust’s petition on December 31, 1987.
On February 9, 1988, Savers filed a supplemental motion for summary judgment, supported by affidavits and copies of the trustee’s foreclosure deeds, and informed the court that the foreclosures of the two properties had resulted in the referenced credits to appellants’ indebtedness. Appellants filed a response to the supplemental motion for summary judgment in which they asserted only that there was no deficiency because, when foreclosed on, the Richardson Tech Center had a fair market value of $6,000,000 and the East Collins Road property had a fair market value of $2,000,000, which in combination exceeded the amount owed on the Note (there being no dispute as to that amount). Two affidavits were attached to this response, one as to the value of the Richardson Tech Center, the other as to the value of the East Collins Road property. In rejoinder, Savers objected to the affidavits as not being made on personal knowledge, and further asserted that in any event market value was irrelevant because there was no claim that there was any irregularity in the foreclosure which caused or contributed to any inadequacy in price. Responding on March 28, 1988 to this rejoinder, appellants merely contended that the affidavits as to market value were not hearsay. On April 26,1988, the district court granted Savers’ motion. The court concluded that the facts were undisputed and that appellants had asserted only two matters in opposition to the motion for summary judgment, namely, that they signed the guaranty “on the understanding” that their liability would be limited to $750,000 and that the value of real estate at the time of foreclosure exceeded the amounts credited on the Note when Savers purchased the property at the foreclosure sales. The district court rejected the former contention, and no complaint is made in this regard on appeal. As to the latter contention, the district court ruled that the value of the property was immaterial since there was no claim of any irregularity in the foreclosures. On May 10, the court entered a final judgment for Savers and against appellants for $3,600,979.67 plus interest and court costs.
Thereafter, appellants, who had obtained new counsel on May 6, 1988, filed on May 24, 1988 motions for leave to file a supplemental answer, for a new trial, to vacate and/or to reconsider summary judgment and for a rehearing, and, subsequently, for leave to file an original counterclaim and to join the Trust. By way of these pleadings, appellants attempted to assert various new defenses to Savers’ claims. The court denied all of these post-judgment motions on August 4, 1988.
Discussion
Appellants’ contentions on appeal fall into two categories, those based on the record as it stood when the district court rendered summary judgment, and those based on denial of appellants’ post-judgment motions. We consider them in that order.
I
Summary Judgment
(a) Note acceleration and foreclosure procedure
Appellants attack the summary judgment on three grounds. The first two, which we consider in this part (a), are that there was inadequate demand and notice of intention to accelerate and that the Rich *1501 ardson Tech Center trustee foreclosure sale was procedurally improper.
We reject each of these two contentions because they were never even hinted at prior to the post-judgment motions. To allow them to be first raised after judgment “would encourage trial by ambush.”
Smith v. Olin Chemical Corp.,
Here we conclude that Savers made an adequate prima facie showing of proper acceleration and foreclosure so as to authorize the summary judgment granted in the absence of any challenge by appellant to the propriety of the acceleration or of the foreclosure procedures. 6
*1502 (b) Inadequate price at foreclosure
Appellants did properly raise in opposition to Savers’ supplemental motion for summary judgment the contention that there was no deficiency on the Note because the asserted fair market values of the properties when foreclosed — approximately $8,000,000 or twice the $4,000,000 total for which Savers bid in the properties and credited the Note — exceeded the *1503 amount then outstanding on the Note (there being no dispute as to that amount). We hold that the district court properly rejected this contention.
We conclude under controlling and long-established Texas law that where there has previously been a valid nonjudicial deed of trust foreclosure on real property securing a debt, the amount to be credited on the debt for deficiency judgment purposes is the amount received at the foreclosure sale; that inadequacy of the consideration received on the foreclosure sale cannot alone invalidate an otherwise valid deed of trust nonjudicial foreclosure on real estate; that in order for inadequacy of consideration to have that effect, there must also be some irregularity in thе foreclosure which caused or contributed to cause the real property to be sold for a grossly inadequate price; and that all these rules are fully applicable where the creditor is the purchaser at the foreclosure.
Tarrant Savings Ass’n v. Lucky Homes, Inc.,
Appellants rely on three recent court of appeals decisions, two by the Beaumont Court,
Lee v. Sabine Bank,
Lee
involved a deficiency claimed by a mortgagee who had foreclosed its “first preferred maritime mortgage on the [mortgagor’s] vessel” in what were apparently judicial foreclosure proceedings in Baton Rouge, Louisiana, where the mortgagee purchased the vessel “at a marshal’s sale.”
In
Halter,
the Beaumont Court
was
faced with a deficiency suit following nonjudicial foreclosure of a deed of trust on real estate. The trial court granted the creditor bank’s motion for summary judgment, calculating the deficiency based on the amount for which the property sold at the foreclosure, despite the debtor’s opposition evidence that this amount was approximately one-third of the property’s then market value. On the debtor’s appeal, the
Halter
court rejected the argument that gross inadequacy of consideration paid by the creditor at a trustee’s sale is not alone enough to justify calculating the deficiency on a basis other than the foreclosure price. Nevertheless,
Halter
affirmed the trial court’s judgment because “the trial court had no evidence before it that the [creditor] Bank or its surrogate purchased the property at foreclosure.”
Moreover, this
Halter
dicta is not persuasive. In the first place, the only authority cited in support of it is
Lee,
which is itself unpersuasive dicta in this respect for the reasons above noted.
Halter
does attempt to distinguish the Texas Supreme Court’s decision in
American Savings & Loan Ass’n v. Musick, supra,
which held that gross inadequacy of consideration paid by the creditor at the nonjudicial foreclosure sale was not grounds for setting the sale aside unless there was an irregularity in the sale which caused or contributed to cause the real property to be sold for a grossly inadequate price.
Halter
reasoned that
Musick
did not apply because it dealt only with the validity of the foreclosure sale, not with the issue of a deficiency judgment.
Halter,
In the second place, Halter’s attempt to distinguish
Musick
on the basis that it involved only the validity of the foreclosure sale, and not any issue of deficiency, also fails to take account of the Texas Supreme Court’s decision in
Maupin v. Chaney, supra
— likewise not cited in
Halter
— where it was held that if the deed of trust nonjudicial forеclosure sale at which the creditor purchased the property was valid then the creditor was entitled to a deficiency judgment with the credit being in the amount for which the creditor purchased the property at the sale, rather than in the amount
*1505
of the assertedly then higher market value of the property.
Maupin,
The remaining case relied on by appellants in this connection is the El Paso Court’s decision in
Olney,
We are likewise not persuaded by Justice Fuller’s Olney opinion. 11 To begin with, the language in Justice Fuller’s opinion relied on by appellants is essentially dicta. The points to which this language was related concerned the admissibility of evidence, which the opinion states was admissible on other grounds in any event; further, reversal and remand was likewise in any event required on still other grounds. Nor is the dicta persuasive, as it relies only on Lee and our Heller opinion, both of which are Ship Mortgage Act cases, as discussed above. Justice Fuller’s Olney opinion does not cite or attempt to distinguish the controlling Texas Supreme Court decisions such as Tarrant Savings Ass’n, Musick, and Maupin.
In this diversity case we are bound to apply Texas law, whether or not we “agree” with it. But it is settled Texas law that a Texas Court of Appeals must, in civil cases, follow the law as established by the Texas Supreme Court. The dicta in Lee, Halter, and Olney, relied on by appellants, is contrary to the Texas Supreme Court’s holding in Tarrant Savings Ass’n. Moreover, the Texas Supreme Court’s holdings in Maupin and Musick taken together likewise demand rejection of this dicta.
We are further strengthened in this conclusion by our consideration of the Texas statutory scheme regulating real estate foreclosures under deeds of trust with power of sale. For at least the last century, Texas has had statutes directed solely at the governance of that particular subject matter. Presently, the relevant statute is Tex.Prop.Code § 51.002. Predecessor statutes include Acts 1889, at 143; Acts 1915, at 84; Acts 1915, 1st C.S., at 32; Article 3810, Revised Civil Statutes of 1925. These enactments all generally required that the sale be in the county where the land was located 12 “at public vendue between the hours of 10 o’clock a.m. and 4 o’clock p.m. of the first Tuesday in any month” and that for at least three consecutive weeks prior thereto written notice of the sale have been posted at the county courthouse door and at two other “public” places in the county. While the statute remained for many years thereafter in the form in which it appeared in the 1925 revision, it was substantively amended in 1975, 1983-84, and 1987. The 1975 amendments merely eliminated the requirement for posting notice of the sale at places other than the courthouse door and added the require *1507 ment that written notice of the sale be given by certified mail at least twenty-one days in advance to each debtor obligated to pay the debt according to the records of the holder thereof. Acts 1975, 64th Leg., at 2354, ch. 723, § 1. As the parties to be notified by certified mail were defined only in terms of their being obligated on the indebtedness secured, rather than their ownership intеrest in the land, it is plain that the legislature was addressing itself to the matter of deficiency judgments. The 1983 and 1984 amendments only added the requirement that a copy of the posted notice be filed with the county clerk and held available for public inspection until after the date of sale. Acts 1983, 68th Leg., at 5056, ch. 915, § 1; Acts 1984, 68th Leg., 2d C.S., at 218, ch. 18, § 3. 13 The 1987 amendments (effective January 1, 1988) again merely added several particular requirements, generally summarized as follows: the sale must take place at the courthouse, either in the area thereof previously designated for such sales by the commissioners court or, in default of such designation, at the courthouse area designated in the notice of sale; the notice also has to state the earliest time of day at which the sale will occur and the sale must begin then or not later than three hours thereafter; in the cаse of “real property used as the debtor’s residence,” the debtor must be served by certified mail with written notice that “the debtor is in default under the deed of trust” and be given “at least 20 days to cure the default before the entire debt is due and notice of sale is given.” Acts 1987, 70th Leg., ch. 540.
Thus Texas nonjudicial foreclosure sales of real estate under deed of trust powers have for approximately a century been conducted pursuant to a special, structured and formal statutory scheme calling for public sales between 10:00 a.m. and 4:00 p.m. of the first Tuesday in each month preceded by three weeks’ public notice. This statutory scheme, by its own terms, applies only to real property sales. The amendments to the statute in 1975, 1983-84, and 1987 preserved the basic scheme, but added specific provisions designed to enhance the fairness of the sale, the likelihood there would be public bidders, and the protection of debtors in respect to deficiency actions. These amendments were made well
after
the Texas Supreme Court’s decisions in
Tarrant Savings Ass’n
and
Maupin
(and, except for the 1975 amendments, after Mustek) which held that gross inadequacy of price (absent an irregularity in the sale contributing thereto) was not a basis on which to set aside a real estate deed of trust foreclosure, even though the creditor was the purchaser, and that if the sale were valid, the foreclosure sales price, rather than the then market price, constituted the proper amount to credit on the debt for deficiency judgment purposes, again even though the creditor was the purchaser at foreclosure. Accordingly, the Texas Legislature may be deemed to have found that the rules applied in those cases were appropriatе components of a proper scheme for regulating real estate nonjudicial foreclosures, and consequent deficiency claims, which did not need to be changed except in the specific respects addressed by the amendments.
Cf. Coastal Industrial Water Authority v. Trinity Portland Cement,
*1508 The decisions of the Texas Supreme Court in Tarrant Savings Ass’n, Maupin, and Musick are decisive against appellants’ claim that summary judgment should have been denied because of their tendered defense that the foreclosure sales price was only half the then market value of the property and that the property’s then market value exceedеd the amount of the outstanding debt.
II
Post-Judgment Motions
All the facts on which appellants’ post-judgment motions were based were clearly actually known to them months before Savers’ supplemental motion for summary judgment was filed on February 9, 1988, and indeed almost all such matters were known to them long before this suit was filed in April 1987.
15
Appellants were represented by counsel throughout the pendency of this action in the district court and filed an answer, a response to Savers’ original motion for summary judgment and, on March 1, 1988, an additional response to Savers’ supplemental motion for summary judgment. The district court did not act on Savers’ supplemental motion until April 26, 1988, at which time the last filing by any party which it had before it was appellants’ March 28, 1988 letter brief. No request for continuance was made. The district court’s April 26, 1988 ruling granting summary judgment was a carefully considered disposition on the merits. Final judgmеnt was not entered until May 10, 1988. Some two weeks later, appellants’ post-judgment motions were filed. Unlike the situation in the decisions relied on by appellants, such as
Seven Elves, Inc. v. Eskenazi,
Conclusion
On the basis of the case as it then stood, the district court’s grant of summary judgment was proper. Moreover, there was no abuse of discretion in its denial of the post-judgment motions. Accordingly, the judgment below is
AFFIRMED.
Notes
.The Note provided: "If default be made in the payment of any installment of principal or interest under this Note and such default shall not be cured within ten (10) days after written notice of default is sent to Maker ... then ... the holder hereof may, at its option, declare the entire principal balance of and accrued interest on this Promissory Note immediately due and payable without notice or demand_’’ It further states: "Except as expressly provided herein, the Maker and any sureties, guarantors and endorsers of this Note jointly and severally waive demand for payment, presentment for payment, protest, notice of nonpayment or dishonor, notice of intent to accelerate, notice of acceleration, ... notice and protest_’’
. No reason for this inability was asserted in certain instances; in other instances, it was asserted that appellants had “insufficient knowledge"; in the remaining instances, it was asserted that the allegation in question "calls for a legal conclusion.”
. This matter of the understanding of appellants concerning the extent of their liability on the guaranty is not raised on appeal.
. Likewise, it is settled that the correctness of a district court’s grant of summary judgment may not be determined on the basis of evidential material first put of record after the summary judgment is granted.
See, e.g., Waltman v. International Paper Co.,
. Similarly, an appellant has "waived its arguments not presented below” and "we will not disturb ... [a district court] decision on the basis of a legаl theory asserted for the first time on appeal.”
McDonald v. Board of Mississippi Levee Commissioners,
.In their answer, appellants expressly
admitted
the allegations of the complaint that on November 24, 1986, the Note was in default for nonpayment of the August through November 1986 interest installments, and that Savers gave appellants and the Trust written notice of such default "and demanded payment for the past due installments and expressed its intent to accelerate should the defaults not be timely cured” and, “the defaults not having been cured,” accelerated the Note on January 28, 1987 and gave written notice thereof to appellants and the Trust. Appellants now contend that the November 24 notice, copy of which was attached to the
*1502
complaint, was deficient because it did not clearly demand payment to cure the default and did nоt refer to the ten-day grace period provided in the Note
(see
note 1,
supra).
However, the Note (which was before the district court for summary judgment), although it does require written notice of default — which was complied with — expressly waives,
inter alia,
"demand for payment" and "notice of intent to accelerate” (as well as "presentment for payment,” etc.).
See
note 1,
supra.
Such waivers are valid.
See Real Estate Exchange, Inc. v. Bacci,
Appellants also claim that the deed of trust foreclosure on the Richardson Tech Center was improper because the substitute trustee’s deed for the September 1, 1987 foreclosure sale showed that the prior sale thereof on August 4, 1987 had been rescinded by Savers and the substitute trustee because "there might have been certain deficiencies” in the notice of sale. The summary judgment affidavits showed that Savers was the purchaser at both sales and that at each the price was S3,000,000, and that the credit on the Note in that amount was made as of August 4, 1987. Contrary to appellants’ argument, it is not necessarily the case that a trustee under a deed of trust cannot resell after an initial sale is found to have been invalid.
See Texas Loan Agency v. Gray,
We further observe that the affidavits filed in reference to appellants’ post-judgment motions reflect that the only deficiency in the notice respecting the August 4, 1987 sale was that the written notices to the debtors were hand delivered to them twenty-one days before the sale, rather than being mailed to them certified mail as required by Tex.Prop.Code § 51.002(b)(3). Although a sale without he required twenty-one days’ notice is invalid or void,
Lido Int'l v. Lambeth,
. Indeed, even under federal law, the issue did not have to be reached, as
Lee
found there was nо evidence of the ship's market value, and hence affirmed the trial court's calculation of the deficiency based on the price paid by the mortgagee at foreclosure.
. We also note that there may be a certain arbitrariness in using the fair market value standard in the deficiency context, but not in challenges to the foreclosure sale. Under such an approach, the creditor who acquires the property by a less than market value bid (for credit on the debt) at foreclosure would profit at the debtor’s expense if the market value exceeds the outstanding debt, but not otherwise. Thus the debtor who borrows giving more security, or who pays his debt down further before defaulting, would on that account receive less protection under such an approach.
. We further observe that if the creditor can be the purchаser at foreclosure only by assuming the risk that a jury in a later deficiency action may find that the property's fair market value exceeded the purchase price, then the creditor (having in mind the notorious imprecision and wide range of real estate fair market value calculations) might well in certain instances prefer to allow the property to be sold to a third party for a lesser amount (which under Halter would not be subject to later question), with ultimate prejudice to the debtor. Of course, if the debtor is insolvent or has no significant nonexempt property, then the creditor would likely not be influenced by such considerations; but, by the same token, in instances of that kind a deficiency action would similarly be unlikely.
.The opinion does not recite the amount of the original debt, or how much was outstanding just before foreclosure, or what amount of dеficiency Home asserted.
. Justice Woodard was the third justice on the
Olney
three-judge panel.
. Though the statutes did not expressly specify that the sale be at the courthouse, this was the virtually universal custom.
Cf. Dall v. Lindsey,
. In the codification of former article 3810, as amended, into section 51.002 of the Texas Property Code, which was enacted by Aсts 1983, 68th Leg., ch. 576, certain changes in arrangement or style of wording were made (for example, “public sale at auction" replaced "sale” "at public vendue"), but these changes were declared to be nonsubstantive. Id. § 7.
. It is also to be noted in this connection that the Texas statutory system regulating most nonjudicial foreclosures of liens on personal property, as contained in the Uniform Commercial Code, initially adopted in Texas in 1965, Acts 1965, 59th Leg., ch. 721, and now codified as Title 1 of the Texas Business and Commerce Code, is plainly separate and distinct and different from the Texas statutory system regulating *1508 nonjudicial real estate lien foreclosures as provided in Tex.Prop.Code § 51.002 (and predecessor statutes). These Uniform Commercial Code provisions are generally contained in Tex.Bus. & Com.Code § 9.504. They are inapplicable to real estate foreclosures. See Tex.Bus. & Com. Code § 9.102 & official comment 4; § 9.104(10) & official comment 2; § 9.501(d). The provisions of section 9.504 omit many of the requirements contained in Tex.Prop.Code § 51.002, such as that sales must always be on a given day of the month between specified hours at a specified courthouse location, and that particular types of notice be given for a specified time in a specified manner; nor does section 9.504 require a public sale (although the secured party's right to purchase at private sale is limited). On the other hand, section 9.504 does contain a requirement, which has no counterpart in Tex. Prop.Code § 51.002, that "every aspect of the disposition including the method, manner, time, place and terms must be commercially reasonable.” Section 9.504 has been amended on several occasions. See, e.g., Acts 1973, 63d Leg., at 999, ch. 400, § 5; Acts 1975, 64th Leg., at 942, ch. 353; Acts 1977, 65th Leg., at 333, ch. 163. Had the legislature, when enacting or amending section 9.504, or when amending section 51.002 in 1975, 1983, and 1987, desired to include some requirement for commercial reasonableness in the law governing real estate nonjudicial foreclosure sales, or some restriction on the creditor’s right to purchase at such sales, it would presumably have done so on one of those occasions. But it did not.
. The post-judgment motions raised claims that certain correspondence from Savers to appellants in November and December 1986 and January 1987, taken together with oral conversations during that time between appellants and officers of Savers, constituted an agreement to amend the loan, or a withdrawal or waiver of demand or of the right to accelerate, or formed the basis for an estoppel preventing demand or accelerаtion, or rendered Savers’ demand and acceleration a breach of a duty of good faith and fair dealing. These motions also asserted that in any event demand and notice of acceleration were insufficient; and that the consideration received at the trustee's sales was inadequate; and that the September 1987 sale was improper because the August 1987 sale had been rescinded. Appellants also sought to file a counterclaim against Savers based on an asserted November 1986 agreement to restructure the loan, and to join the Trust as a party in the counterclaim.
. We note that in this case, unlike
Crutcher,
appellants’ post-judgment motions were filed within the time allowed by Fed.R.Civ.P. 59, computed under Fed.R.Civ.P. 6(a), and were hence to be deemed Rule 59 motions at least "for purposes of Fed.R.App.P. 4(a)(4).”
