The MARS Rule (Regulation O): the loan-modification advance-fee ban, explained

Our other Library pages mostly cover getting a mortgage. This one covers a different, later moment: a homeowner already struggling with payments, being pitched "guaranteed" loan-modification or foreclosure-rescue help by a company that isn't their own lender or servicer. A specific federal rule — Regulation O, still widely known by its original name, the MARS Rule — was built around exactly that scenario, and it starts with a flat ban on collecting money up front.

Where this rule comes from

Congress directed the FTC to write mortgage-relief-marketing rules under Section 626 of the Omnibus Appropriations Act, 2009. The FTC's resulting Mortgage Assistance Relief Services (MARS) Rule took effect in stages through 2010 and 2011, with the advance-fee ban itself becoming enforceable January 31, 2011. Dodd-Frank then split enforcement: the CFPB republished the same rule as Regulation O at 12 CFR Part 1015 in December 2011 — the same month it republished the mortgage-advertising rule our Regulation N explainer covers as a companion rule — and the FTC and CFPB now share enforcement authority over it, the same dual-regulator structure Regulation N uses.

Who the rule actually covers

A "mortgage assistance relief service" is any product or service marketed as helping a consumer with a mortgage that's delinquent, in default, or at risk of either — loan modifications, forbearance arrangements, short sales, and foreclosure-rescue services are the core examples. The rule reaches "any person" who provides, offers to provide, or arranges for someone else to provide that kind of help — a broad definition that can cover an individual loan officer or broker who markets loss-mitigation "relief" services on the side, not just dedicated foreclosure-rescue firms. It specifically excludes the consumer's own dwelling-loan holder, their servicer, and either one's own employees or agents acting within that role — the rule targets a third party inserting itself into the relationship, not the lender or servicer working directly with its own borrower.

The advance-fee ban itself

Under 12 CFR § 1015.5, a covered provider cannot request or receive any fee or other payment until two things have both happened: the consumer has received a specific written offer of mortgage relief that the provider actually obtained from the consumer's own lender or servicer, and the consumer has executed a written agreement incorporating that offer. A provider who never actually secures a real offer from the consumer's lender or servicer, in other words, has no lawful way to collect payment at all under this rule — "guaranteed results" marketing paired with an up-front retainer fee is close to the exact pattern the rule was built to stop.

The disclosure the offer itself has to carry

When a provider does deliver a written offer obtained from the lender or servicer, § 1015.5(a)(2) requires it to include a specific statement making clear the consumer is free to walk away: that the offer came from their own lender or servicer, that they may accept or reject it, and that they owe the provider nothing if they reject it. The provider also has to describe, in writing, the material differences between the consumer's current loan terms and the terms under the new offer — so a consumer is comparing the actual numbers, not a marketing summary of them.

Other conduct the rule separately prohibits

Beyond the fee timing itself, Regulation O separately bars a provider from telling a consumer to stop communicating with their own lender or servicer, from representing that a specific outcome (like a modification being approved) is likely when the provider has no reliable basis for that claim, and from making any material misrepresentation about the service at all — echoing the CFPB's broader UDAAP authority our UDAAP explainer covers, applied here to one specific, named category of conduct.

What this page is, and isn't: an explanation of a real federal advance-fee rule, for general understanding — not a claim that any specific company or individual has violated it. If you're being asked to pay before a lender-approved offer is in hand, that's the specific fact pattern to check against this rule and, where warranted, report — see our guide to filing a complaint.

What to actually check

Before paying anyone who isn't your own lender or servicer for loan-modification or foreclosure-rescue help, ask directly whether they've already obtained a written offer from your lender or servicer, and don't pay until you've seen it in writing along with the required comparison of your current and proposed terms. Your lender or servicer's own loss-mitigation department can also be contacted directly, free, without going through a third party at all.
