A foreclosure auction in the United States is the last step of a process that two levels of law share. Federal rules, written by the Consumer Financial Protection Bureau (CFPB), say when a mortgage servicer may begin a foreclosure and when a sale has to wait for a borrower's request for help. Almost everything else, from the notices to the auction itself and what follows it, belongs to the state where the home stands.

This guide follows the process in order, using only what federal sources say: the CFPB and its Regulation X, the Department of Housing and Urban Development (HUD), and the Internal Revenue Service (IRS), whose manual describes foreclosure from the position of a creditor holding a lien behind the mortgage. Where those sources hand the question to state law, the guide says so. It does not cover how federal agencies sell homes they already own, which is a different subject.

Regulation X, section 1024.41, paragraphs (f) and (g); Internal Revenue Manual 5.12.4, revised 25 June 2024. The IRS notice applies where a federal tax lien is filed.

What federal sources mean by foreclosure

The CFPB gives two plain definitions. Its page on how foreclosure works, last reviewed on 3 April 2024, says foreclosure is when the lender takes action to satisfy the homeowner's debt out of the sale of the collateral, meaning the homeowner's property, when the homeowner fails to make payments on a mortgage. Its glossary of mortgage terms is shorter: foreclosure is when the lender or servicer takes back property after the homeowner fails to make mortgage payments. The first definition describes a sale, the second a repossession, and the CFPB notes that the lender itself may bid at the auction and becomes the buyer if its bid is the highest.

The IRS looks at the same event from the other side of the title. Its Internal Revenue Manual, in a section revised on 25 June 2024, defines a foreclosure as the process by which an owner's right to a property is terminated, and adds that junior interests are extinguished. That second half matters to a bidder: a foreclosure by a senior lender is designed to clear the claims that rank behind it, subject to the conditions described later in this guide.

Three other terms recur. The CFPB glossary describes the security interest as what lets the lender foreclose if the borrower does not repay. It defines "delinquent" as another term for being late on payments. And it defines loss mitigation as the steps mortgage servicers take to work with a borrower to avoid foreclosure. It is the servicer that the federal timing rules bind.

Judicial, power of sale and strict foreclosure

The IRS manual states the starting point: state law determines whether a foreclosure is conducted judicially or non-judicially, and the location of the property determines which state's law applies. HUD's page on the foreclosure process makes the same point more broadly, saying foreclosure processes are different in every state, including the notices that must be posted or mailed, the redemption periods, and the scheduling and notices of auctions.

HUD describes three types. In a judicial foreclosure the lender files suit. The CFPB says this route requires the process to go through a court, where the borrower can raise defences. In a power of sale foreclosure, which HUD also calls statutory, there is no court action: the CFPB says it follows steps that include required written notices under a "power of sale" clause in the mortgage or deed of trust. The IRS manual explains that such a clause pre-authorises the sale of the property by the lender outside a court's jurisdiction if the borrower defaults, and that the sale must still comply with state statutes. In a strict foreclosure, the lender sues and, if the borrower does not pay within the timeline the court orders, the property goes directly back to the mortgage holder with no auction at all.

HUD adds two details. It says power of sale auctions are often faster than judicial ones, and that strict foreclosure generally happens only when the debt exceeds the value of the property. It also says all three types require public notices and notice to all parties. None of the federal pages read for this guide lists which states fall under which type, so the type that applies to a given home has to be read from that state's own law.

The federal 120-day rule

Whatever the state, a servicer covered by Regulation X cannot start straight away. Paragraph (f)(1) of section 1024.41 says a servicer shall not make the first notice or filing required by applicable law for any judicial or non-judicial foreclosure process unless the borrower's mortgage loan obligation is more than 120 days delinquent.

The paragraph has two exceptions. The 120-day wait does not apply when the foreclosure is based on a violation of a due-on-sale clause, or when the servicer is joining the foreclosure action of a superior or subordinate lienholder. Small servicers are expressly kept inside this rule: paragraph (j) says a small servicer is subject to the prohibition in paragraph (f)(1).

HUD's general description sits a little differently from the regulation, and both are worth holding in mind. HUD says late fees are charged after 10 to 15 days, that after 30 days the borrower is in default, and that mortgage companies generally start foreclosure three to six months after the first missed payment. The CFPB's consumer page says the process may begin when a borrower falls "a few months behind", though it can begin earlier or later. Regulation X is the precise version of the same idea: the earliest legal step waits until the loan is more than 120 days delinquent, which is roughly four months.

What counts as the first notice or filing

The regulation uses the phrase "first notice or filing" without defining it. The CFPB's official interpretation fills the gap, and its answer changes with the state's procedure. Comment 41(f)-1 gives three cases:

1. Where foreclosure requires a court action or proceeding, it is the earliest document required to be filed with a court or other judicial body to commence that action.
2. Where no court action is required but state law requires a document to be recorded or published, it is the earliest document required to be recorded or published to initiate the foreclosure process.
3. Where neither a court filing nor recording or publication is required, it is the earliest document that establishes, sets or schedules a date for the foreclosure sale.

The same comment sets a limit. A document given to the borrower that was not initially required to be filed, recorded or published does not become the first notice merely because it must later be attached to a document that is filed. The federal clock is thus tied to the formal step that opens the foreclosure under state law, and which document that is depends on the state.

What the servicer must do in the first 45 days

The four months are not meant to pass in silence. Section 1024.39 of Regulation X, on early intervention, gives the servicer two duties while the borrower stays delinquent. First, it must establish live contact with the borrower, or make good faith efforts to, no later than the 36th day of the delinquency, and again no later than 36 days after each payment due date. After that conversation it must promptly tell the borrower about loss mitigation options, if appropriate.

Second, it must send a written notice no later than the 45th day of the delinquency. The regulation lists what the notice holds: a statement encouraging the borrower to contact the servicer, the telephone number of the personnel assigned to the borrower and the servicer's mailing address, a brief description of examples of loss mitigation options if applicable, application instructions or how to obtain more information, and the website for the CFPB or HUD list of homeownership counsellors together with HUD's toll-free number. The servicer need not send this notice more than once in any 180-day period.

The standard notice does not have to mention foreclosure. A statement that the servicer may or intends to invoke foreclosure is required only in a modified notice sent to a borrower who has sent the notification provided for in section 805(c) of the Fair Debt Collection Practices Act; that notice may not contain a request for payment. A separate set of adjustments applies while a borrower is in bankruptcy, when the live contact duty is lifted.

The dates above are illustrative and rest on one assumption: that the due date is the first day of the delinquency. The sections of Regulation X read for this guide do not spell out how the days are counted, so the exact day in a real case depends on the regulation's definitions and on the loan.

How an application for help changes the timetable

The review period has a second effect, set out in paragraph (f)(2). If a borrower submits a complete loss mitigation application during those first 120 days, or at any time before the servicer has made the first notice or filing, the servicer may not make that first notice or filing unless one of three things has happened. The servicer has sent a notice that the borrower is not eligible for any option and the appeal is not available, was not used in time or was denied. Or the borrower has rejected every option offered. Or the borrower has failed to perform under an agreement on a loss mitigation option.

Regulation X does not promise a result. Paragraph (a) says nothing in the section imposes a duty on a servicer to provide any borrower with any specific loss mitigation option. What the section regulates is procedure, and a borrower may enforce it under section 6(f) of the Real Estate Settlement Procedures Act. The procedure is tied to how far away the sale is on the day the complete application arrives.

Two further deadlines sit beside the table. Under paragraph (b)(2), when any application arrives 45 days or more before a foreclosure sale, the servicer must review it promptly and tell the borrower in writing within five days, not counting Saturdays, Sundays and legal public holidays, that it has been received and whether it is complete; if it is not, the notice gives a reasonable date for the missing documents. And where an appeal is available, paragraph (h) gives the borrower 14 days to lodge it and the servicer 30 days from the appeal to decide. That decision cannot be appealed again.

The CFPB's commentary answers the obvious question of what happens when no sale date exists yet. An application received when no foreclosure sale is scheduled is treated as received more than 90 days before any sale, and the protections fixed on the day of receipt stay in place even if a sale is later scheduled or rescheduled. There is one brake on repeat requests: under paragraph (i), a servicer that has already complied for one complete application need not do so again if the borrower has been delinquent at all times since.

When a scheduled sale has to wait

Once the first notice or filing has been made, paragraph (g) takes over. If the borrower submits a complete application after that step but more than 37 days before a foreclosure sale, the servicer may not move for a foreclosure judgment or an order of sale, and may not conduct a foreclosure sale, unless one of the same three conditions is met: an ineligibility notice with the appeal exhausted or unavailable, rejection of all offers, or failure to perform under an agreement.

The commentary spells out how far that reaches. The bar covers a dispositive motion such as a motion for default judgment. A servicer that filed such a motion before the complete application arrived does not break the rule if it takes reasonable steps to avoid a ruling on it. The servicer must promptly instruct its foreclosure counsel not to file a dispositive motion, to avoid a ruling on a pending one and to prevent a sale that is already scheduled, and it is not excused if counsel's conduct causes a violation. The bar also applies when someone other than the servicer conducts the sale.

What paragraph (g) does not do is freeze the file. The commentary says the servicer may continue the foreclosure process, including publication, arbitration or mediation, so long as those steps do not cause or directly result in a foreclosure judgment or order of sale. Publication of a sale can therefore continue while an application is under review.

A worked example, with a sale assumed for Monday 1 June 2026: 90 days before the sale is 3 March 2026, 45 days before is 17 April 2026 and 37 days before is 25 April 2026. A complete application received on 24 April is 38 days ahead and falls under paragraph (g); one received on 25 April does not. Two other situations stop a sale regardless of these dates: a servicer may not make the first notice or filing, seek judgment or conduct a sale while a borrower is performing under a short-term forbearance or repayment plan, which the commentary describes as covering payments due over no more than six months, and a small servicer may not do so while a borrower is performing under a loss mitigation agreement.

Notices of the sale: state law, and one federal notice

No federal page read for this guide sets the content or timing of the notice of sale that the public sees. The CFPB says state foreclosure processes require that the borrower be notified of the proceedings. HUD says all three types of foreclosure require public notices and notice to all parties, and that the notices to be posted or mailed are among the things that differ from state to state. On HUD's description of a judicial foreclosure, the borrower receives a letter demanding payment once the lender has filed suit and has only 30 days to respond with a payment; in a power of sale foreclosure, notices demanding payment come first and the auction follows a waiting period.

There is one notice that federal law itself attaches to a non-judicial sale, and it goes to the government rather than the owner. Where a Notice of Federal Tax Lien has been filed against the property, the Internal Revenue Manual says the party conducting the sale must notify the IRS in writing, by registered or certified mail or by personal service, no less than 25 calendar days before the sale. The notice goes to the office the manual names as Advisory Consolidated Receipts and must give the name and address of the sender, a copy or list of each tax lien notice, a detailed description of the property with its address and legal description, the date, time, place and terms of the sale, the approximate principal owed including interest, and a description of other expenses chargeable against the proceeds.

On the assumed sale date of 1 June 2026, the notice would have to be given by 7 May 2026, and a tax lien notice filed after 1 May 2026 would fall inside the 31-day window. The manual adds that a notice sent on time is treated as adequate unless the IRS rejects it in writing more than five calendar days before the sale, that a postponed sale needs a notice of postponement, and that consent to a sale must be in writing and cannot be given after the sale date. In a judicial foreclosure the route is different: the manual says the United States consents to be sued in a suit to foreclose a mortgage or other lien.

The auction itself

The CFPB describes the sale in three sentences. A public auction of the property generally will be held. Prospective buyers, including the lender, attend. The property is sold to the highest bidder, and the lender becomes the buyer if its own bid is the highest. Who stands at the front depends on the type: by HUD's account a local court or the sheriff's office conducts the auction in a judicial foreclosure, while in a power of sale foreclosure the mortgage company holds the auction itself, not a court or sheriff.

The IRS manual names North Carolina as an example of a state that allows upset bidding; the passages read for this guide do not set out how that procedure works. The federal pages read here do not describe the deposit a bidder must bring, the time allowed to pay the balance or the form of deed, and the CFPB says only that additional state laws set out how the property is conveyed to the buyer. It also notes that some states may give borrowers a right to mediation before foreclosure.

Two consequences follow the sale. For the occupants, HUD says families have a small amount of time to find housing and move out before the sheriff issues an eviction; it gives no number of days. For the money, a sale can raise more than the foreclosing lender is owed. The IRS manual says surplus proceeds may be held by the party that conducted the sale or by another party designated by state law, and that the IRS has two ways to reach them: filing a claim or issuing a levy.

Redemption after the sale

A redemption period is the time after a sale during which the property can still be redeemed. HUD lists redemption periods among the features that differ in every state, without giving any state's period, and the CFPB pages read for this guide do not address the borrower's right of redemption at all. Whether a former owner can redeem, for how long and at what price is therefore a state question that the federal consumer sources leave open.

One redemption right is set federally, and it belongs to the United States. Where a foreclosure sale extinguishes a junior federal tax lien, the Internal Revenue Manual says the government may redeem the property: after a judicial sale it has 120 calendar days from the date of sale, or the state period if longer, and after a non-judicial sale the period is 120 calendar days or the period provided by state law, whichever is longer. The right survives even where the IRS consented to the sale. On a sale held on 1 June 2026 the 120th calendar day is 29 September 2026, which shows the practical effect for a buyer: where a federal tax lien was on the title, ownership acquired at the auction can remain open to redemption for about four months, or longer if the state's own period is longer.

The manual also explains whose foreclosure affects the tax lien. When the foreclosing party ranks ahead of the lien, the sale extinguishes it as it would any junior lien under local law. When the foreclosing party ranks behind it, the sale goes ahead without disturbing the lien, unless the United States agrees to a sale free of it.

The federal rules decide when a foreclosure may begin and when a sale must pause. What the buyer receives, and what the former owner still owes, is decided by the state.

Deficiency: when the sale does not cover the debt

The CFPB defines a deficiency as the difference between the value of the property and the amount still owed on the mortgage loan. A worked example with assumed figures: on a loan balance of US$300,000 and a property value of US$260,000, the deficiency is US$40,000.

Whether the borrower remains liable for that sum depends on the state. The CFPB's pages on deeds-in-lieu, last reviewed on 2 January 2025, and on short sales, last reviewed on 2 February 2024, both treat it that way: the first speaks of living "in a state where you are responsible for any deficiency", and the short sale page says that in some states the lender could sue to collect it. Both pages concern alternatives to foreclosure: a deed-in-lieu is an arrangement in which the owner voluntarily turns over ownership of the home to the lender, and a short sale is a sale of the home for less than what is owed. Both pages refer to a waiver of the deficiency: the short sale page says it means the lender has waived the right to collect the amount, and the deed-in-lieu page says a waiver should be in writing. The deed-in-lieu page adds that a tax liability may still arise.

None of the federal pages read for this guide describes how a deficiency is pursued after a foreclosure auction itself, names the states that allow or bar it, or says which value is used when the lender is the winning bidder. Those answers are in the law of the state where the property stands.
