Your mortgage was denied. That may have been the lender's rule, not the loan's.

First: get the reason in writing

Under the Equal Credit Opportunity Act and Regulation B, a lender must notify you within 30 days of a decision on a completed application, and the notice must state the specific reasons for the denial or tell you how to request them. If a credit score factored into the decision, the Fair Credit Reporting Act requires the notice to include the actual numerical score and name the credit bureau that supplied the report.

That document is the adverse action notice, and everything below depends on it. Don't work from what you think went wrong. Work from what they wrote down.

One distinction worth knowing: if a lender couldn't decide because documents were missing, it may issue a notice of incompleteness rather than a denial. If it had enough information to evaluate you and denied you anyway, it cannot list "incomplete application" as the reason. It has to give you the real one.

Published program rules can differ from a lender's requirements

This is the part that costs people years, and almost nobody explains it.

Government and agency programs publish baseline requirements, while individual lenders may apply additional requirements. The table separates selected official program rules from common lender-level statements; eligibility still depends on the complete file.

So why did the bank say no? Overlays.

A lender may add its own requirements on top of a program's published guidelines. Those additions are called overlays, and they are the reason two lenders give the same borrower opposite answers on the same day.

The program allows a 580 FHA score; the lender requires 640. Automated underwriting may evaluate debt-to-income as part of the full risk profile; a lender may also use its own ceiling. Neither lender is breaking a rule. One is lending to the guideline and the other isn't.

Lenders manage credit risk, investor requirements, operational capacity and quality-control exposure differently. Those differences can produce different internal rules even when the underlying loan program is the same.

An overlay can be stricter than the published program rules. A lender might require a higher score, lower debt-to-income ratio, additional reserves or different treatment of collections. That does not mean another lender must use the same rule, and it also does not mean a different lender will approve the file.

Which means "I was denied" and "I don't qualify" are not the same sentence. Ask your loan officer directly: is this number a program requirement or your overlay? A straight answer tells you whether you're facing a repair job or a shopping problem.

What this looks like in practice

The practical change is that a lower third-party score no longer ends a DU evaluation by itself. The borrower must still receive an eligible DU recommendation and satisfy income, asset, property and lender requirements.

A caution in the other direction, because this page is only useful if it's honest. A DU approval is not a closing — income, assets and the property still have to document and meet guidelines. And on conventional loans, credit score still drives pricing through loan-level price adjustments even where it no longer blocks eligibility. Pricing can still vary materially by score, loan type and the complete scenario, so compare total cost rather than assuming eligibility means the lowest price.

But not every loan fits agency lending — that's what non-QM is for

Everything above assumes your file can work inside a government or agency program once it reaches a lender willing to lend to the guideline. Often it can. Sometimes it genuinely can't, and no amount of shopping changes that.

Agency and government programs share a core assumption: that your income can be documented the way a W-2 employee's income is documented. Tax returns, pay stubs, a two-year history in the same line of work. When that assumption doesn't hold, the file fails for a reason no overlay explains.

That's the gap non-QM lending fills. Non-QM means the loan sits outside the Qualified Mortgage rules. It's a category, not a grade. The situations it's built for:

A self-employed borrower whose tax returns show income after write-offs, when the write-offs are the entire point — a bank statement or P&L program measures deposits instead. An investor buying a rental, where personal debt-to-income says nothing about whether the property pays for itself, and a DSCR loan qualifies on the rent. A retired borrower with significant assets and little reportable income, where asset depletion converts a balance into qualifying income. A borrower whose bankruptcy or foreclosure hasn't met agency seasoning but who is otherwise strong. A property agency guidelines won't accept, like a non-warrantable condo.

Non-QM carries higher rates than agency financing. That's the honest trade, and anyone who tells you otherwise is selling. For many borrowers it's the difference between buying now and waiting two years, and plenty refinance into conventional financing later once the file fits.

The order matters, though. Check whether a government or agency program works first, because it's almost always cheaper. Non-QM is the right answer when agency genuinely doesn't fit — not the first stop because one bank said no.

The reasons mortgages actually get denied — and where each one leads

When the denial is telling you something true

Sometimes the answer really is no for now, and no amount of lender shopping changes it. Being straight about this matters more than the alternative.

If your score reflects recent missed payments rather than a thin file, no program tier fixes that — time and payment history do. If you have no verifiable income by any method, including bank deposits, asset balances or property cash flow, no documentation type manufactures one. If a recent bankruptcy or foreclosure hasn't met the seasoning period, the clock is the requirement. If the down payment would leave you with nothing afterward, a lender approving you would be doing you harm.

And if you're stretching to the absolute ceiling of what someone will approve, an approval is not automatically good news. The denial may be the cheapest advice you ever get.

If you're under contract right now

A denial after you're in contract is a different emergency, and the clock is the problem.

Your financing contingency has a date on it. Talk to your agent or real estate attorney immediately about whether it can be extended — that's a contract question, not a lending one, and getting it wrong can cost your deposit.

Protect the file while you regroup: no new credit applications, no large purchases, no job changes until you close. Lenders re-pull credit before funding, and a new account opened during the gap can undo a second approval.

One thing in your favor: multiple mortgage inquiries made within a focused shopping period may be grouped for scoring purposes, depending on the scoring model. Shopping the same loan across lenders in a short period is not what damages your score.

How to move, in order

1. Get the adverse action notice and read the stated reason. Not your guess — theirs.
2. Ask the loan officer one question: is this a program requirement or your overlay? Write down the answer.
3. Look up what the program actually allows. FHA publishes HUD Handbook 4000.1; Fannie and Freddie publish their selling guides. The floors are public.
4. Pull all three credit reports and check for errors. If something is wrong, dispute it — and ask about a rapid rescore if you're on a deadline.
5. If it's an overlay, the file may go as-is to a lender that lends to the guideline. Nothing to fix.
6. If agency documentation genuinely can't work for your income, move to the non-QM structure that fits — and understand the rate difference before you sign.
7. If it's a real credit, reserve or seasoning issue, get the specific number and the date you'll hit it. Then work to it.

Programs that address this

Check these first — government and agency

Almost always cheaper than the alternatives. If a lender's overlay was the problem, the answer is probably in this row.

When agency genuinely doesn't fit — non-QM

Different documentation, higher rates. The right answer when your income or the property can't work inside agency guidelines.
