While substance counts, procedure does too. This appeal arises out of the Chapter 11 bankruptcy petition of River West Plaza-Chicago, LLC (“River West”). The bankruptcy court disallowed the claim by Appellant, and purported creditor, Frank Schwab, erroneously in his view. As we explain below, however, two procedural impediments prevent us from reviewing the propriety of the bankruptcy court’s disallowance decision because they foreclose any possibility of substantive relief if he were to prevail here. The first is Mr. Schwab’s failure to obtain a stay of the sale of River West’s property pending appeal, as required under 11 U.S.C. § 363(m). The second is his failure to file a notice of appeal that challenged the bankruptcy court’s order approving the joint liquidation plan that distributed the sales proceeds. Mr. Schwab therefore *670 cannot seek to modify the plan here, in an effort to excuse his failure to obtain a stay.
I.
Background
River West was organized to own and operate a single asset: Joffco Square, a shopping center in Chicago. Before it filed for bankruptcy, Mr. Schwab had filed suit against River West in state court, alleging that he was entitled to a percentage of River West’s profits under a written agreement. After the bankruptcy petition, a stay automatically issued against the state-court litigation. See 11 U.S.C. § 362(a). Accordingly, Mr. Schwab filed a notice of claim with the bankruptcy court, so that he could continue to pursue the money that he believes River West owes him.
Although Mr. Schwab argued that a lis pendens that he filed in connection with his state-court lawsuit made his claim a secured one, the bankruptcy court disagreed. At a September 2010 hearing, the bankruptcy court disallowed the claim in its entirety. According to the bankruptcy court, even if the allegations in the state-court litigation were true, Mr. Schwab could have nothing more than an equity interest in River West, which would necessarily be subordinate to all other creditors’ claims and thus worthless.
The timing of what happened after the bankruptcy court disallowed Mr. Schwab’s claim is critical for this appeal.
• October 4, 2010: River West and its largest secured creditor, Bank of America, N.A., file a joint liquidation plan, proposing to sell Joffco Square at auction.
• October 6, 2010: Mr. Schwab appeals the bankruptcy court’s disallowance of his claim to the district court.
• December 9, 2010: Mr. Schwab requests that the bankruptcy court stay the sale of Joffco Square pending resolution of his appeal.
• December 10, 2010: Mr. Schwab requests that the district court stay the sale of Joffco Square pending resolution of his appeal and expedite the briefing of his appeal.
• December 14, 2010: The district court denies the motion for stay as premature, because the bankruptcy court had not issued a ruling on Mr. Schwab’s pending motion for a stay from that court. It does, however, expedite briefing of the appeal.
• December 14, 2010: The bankruptcy court denies Mr. Schwab’s motion to stay.
• December 14, 2010: Mr. Schwab files an objection to the joint liquidation plan with the bankruptcy court, arguing among other things that “confirmation should not take place until the District Court has ruled on Schwab’s appeal....”
• December 15, 2010: The auction of Joffco Square occurs, as scheduled, with Inland Real Estate Corporation’s (“Inland”) bid prevailing.
• December 22, 2010: The bankruptcy court overrules Mr. Schwab’s objection to the joint liquidation plan and enters an order confirming it, which among other things specifies the distribution that each creditor would receive. The bankruptcy court also approves the sale of Joffco Square to Inland, “free and clear of liens, claims, and encumbrances, as provided in Bankruptcy Code section 363.”
• December 28, 2010: The fourteen-day period expires for Mr. Schwab to appeal to the district court the bankruptcy court’s December 14 denial of *671 his motion to stay. See Fed. R. Bankr.Pro. 8002(a).
• January 5, 2011: The fourteen-day period expires for Mr. Schwab to appeal to the district court the bankruptcy court’s December 22 confirmation of the joint liquidation plan. See id.
• January 11, 2011: The joint liquidation plan becomes effective. The sale of Joffco Square to Inland closes.
• February 9, 2011: The bankruptcy court holds a hearing to address any outstanding post-confirmation matters. Mr. Schwab does not attend.
• February 9, 2011: River West and Bank of America move to dismiss Mr. Schwab’s appeal as moot under 11 U.S.C. § 863(m).
• February 23, 2011: The bankruptcy court issues its final decree and closes the bankruptcy.
• April 11, 2011: The district court dismisses Mr. Schwab’s appeal as moot in light of 11 U.S.C. § 363(m).
• May 11, 2011: Mr. Schwab files his notice of appeal to this Court from the district court’s April 11 dismissal.

Discussion
As he did before the district court, Mr. Schwab argues that (1) his state-court notice of lis pendens gave him a property interest in Joffco Square; (2) nothing in the Bankruptcy Code allowed the bankruptcy court to recharacterize that interest as equity; and (3) the bankruptcy court erred in authorizing and confirming a sale of Joffco Square free and clear of his interest, see 11 U.S.C. § 363(f) (authorizing free-and-elear sales only under certain circumstances). The district court held that because Mr. Schwab neither obtained a stay of the sale of Joffco Square nor challenged Inland’s status as a good-faith purchaser, § 363(m) rendered his appeal of the disallowance order moot, and dismissed it.
We review the district court’s finding of mootness
de novo. Hower v. Molding Sys. Eng’g Corp.,
“A central purpose of bankruptcy ... is to maximize creditor recovery.”
Corporate Assets, Inc. v. Paloian,
Given the statutory guarantee of finality that § 363(m) provides, “we have repeatedly held that when a party challenges the bankruptcy court’s order approving the sale of estate property to a good faith purchaser, it must obtain a stay of that order pending appeal, lest the sale proceed and the appeal become moot.”
In re CGI Indus.,
*672
So even if Mr. Schwab were correct that the bankruptcy court should not have stripped away his interest in Joffco Square (which we do not decide), § 363(m) prevents us from resurrecting that interest in the real estate itself. As below, Mr. Schwab does not contest Inland’s status as a good-faith purchaser, which is the sole ground § 363(m) provides for modifying the terms of a sale completed in the absence of a stay.
See In re Sax,
Inland successfully bid to purchase Joffco Square free and clear. With the sale now completed, § 363(m) guarantees that no appellate court will disturb the bankruptcy court’s order that Inland take Joffco Square “free and clear of liens, claims, encumbrances,” including any that Mr. Schwab would like to assert if he could revive his claim here. And despite Mr. Schwab’s suggestion to the contrary, we may not ignore § 363(m) just because Inland is not a party to this appeal and has not, therefore, raised § 363(m) itself.
See In re Vlasek,
Mr. Schwab alternatively argues that he can avoid a challenge to the “validity” of the sale for the purposes of § 363(m), and thus its stay requirement, by asking us to simply rearrange the distribution of the sale proceeds if he prevails. Specifically, he argues that his claim can be paid out of the distribution that went to Bank of America, which is a party to this appeal.
Mr. Schwab’s alternative argument also falters, for two reasons: the effect of his notice of appeal to the district court and, again, § 363(m).
First, the notice of appeal: The only notice filed in the bankruptcy court was Mr. Schwab’s challenge to his claim’s disallowance. Mr. Schwab never appealed the bankruptcy court’s order approving the liquidation plan to the district court. The order established Bank of America’s share of the proceeds. Because Mr. Schwab’s first notice of appeal did not (and cannot) encompass orders that post-date it, the district court could not order the modification of the plan to rearrange the distribution of the sale proceeds.
See In re Vlasek,
Second, just as § 363(m) prevents us from letting Mr. Schwab challenge the sale of the property if he could succeed in reviving his disallowed claim on appeal, it also prevents us from letting him upset the expectations from the sale that River West’s other creditors had when deciding to support the sale. Courts take a dim view of arguments that attempt to craft any sort of “end run around the appeal and stay requirements of § 363(m).”

Conclusion
Having failed to obtain a stay of the sale of the property at issue and having appealed only the disallowance of his claim, Mr. Schwab’s appeal is moot and is, therefore, Dismissed.
Notes
. The narrow exception to this rule that we have previously recognized occurs where, unlike here, the proceeds from the sale of partially exempt property have not yet been distributed to creditors and an exemption attaches to the sale proceeds.
