What is the FHA 90-day flip rule?

It is HUD's rule at 24 CFR 203.37a. A property resold 90 days or less after the seller acquired it is not eligible for an FHA-insured mortgage, with listed exceptions such as HUD's own REO sales.

Can an FHA buyer purchase on a double close?

Generally not on a same-day double close, because you acquire and resell the same day. The resale falls inside the 90-day window, so the property is not eligible for FHA insurance at that point.

Does the 90-day rule apply to conventional loans?

The FHA regulation applies to FHA-insured mortgages. Conventional lenders and other programs may have their own seasoning or title-history requirements, so ask the specific lender.

Is an assignment a way around the FHA rule?

Because you never take title, an assignment does not create a new acquisition date. The FHA lender will still review the transaction and any assignment fee, so confirm with that lender before relying on it.

What happens after 90 days?

The regulation says a resale between 91 and 180 days after acquisition is generally eligible, while giving HUD authority to require more documentation in some cases. Ask the buyer's lender what it will need.

What does the FHA 90-day rule actually say?

The rule lives at 24 CFR 203.37a, HUD's regulation on property flipping. Reading it directly (Cornell LII):

If the resale date is 90 days or less after the seller acquired the property, the property is not eligible for an FHA-insured mortgage.
If the resale is between 91 and 180 days after acquisition, the property is generally eligible, though HUD reserves authority to require more support in certain cases.
The regulation also lists exceptions, including sales by HUD of its own REO properties and certain nonprofit and government-related sales.

"Seller" here means whoever is selling to the FHA borrower. On a double close, that is you.

Why does a double close trip the rule?

Because a double close is two real purchases. You buy from the original owner in the morning and sell that afternoon. Your acquisition date and your resale date are the same day, which is far inside 90 days. If your end buyer's loan is FHA-insured, the property is not eligible.

That is the whole problem in one line, and it is why experienced wholesalers ask "how is your buyer paying?" before they sign a B–C contract.

Does the rule apply to assignments?

With an assignment of contract, you never take title. The end buyer steps into your contract and buys directly from the original seller, so the seller's acquisition date is whatever it was originally. That can avoid the 90-day issue, but FHA lenders also review the full transaction, including any assignment fee. Ask the end buyer's lender how it treats an assigned contract before you rely on that path.

Which end buyers work with a same-day resale?

End buyer's financing	Same-day double close?	What to check
Cash	Generally works	Proof of funds that title can verify
Hard money or private loan	Often works	That lender's own seasoning or title-history rules
Conventional loan	Varies by lender	Ask the lender about seasoning before signing
FHA-insured loan	Not eligible inside 90 days under 24 CFR 203.37a	Plan a different exit or a longer hold

Other loan programs and individual lenders can have their own seasoning requirements. The table above only states the FHA rule as the regulation reads; everything else is a question for the buyer's lender.

A worked example

Example only, with hypothetical round numbers. You have a house under contract at $150,000. A buyer offers $185,000 using an FHA loan.

Double close today: You would acquire and resell the same day. Under the regulation, that resale is inside 90 days, so the FHA loan is not available.
Cash buyer at $175,000: Lower price, but the double close works. Transactional funding covers the A–B purchase, and at Axelrad pricing starts at 1 point of the advance.
Buy, renovate, hold past 90 days: You might sell to the FHA buyer later, but now you need purchase and rehab money for months. That is hard money or bridge territory. See the bridge loan and fix-and-flip pages for current terms.

Each path trades price for time and risk. The regulation does not change; your exit does.

How do you plan around it?

Ask every prospective end buyer how they will pay before you sign the resale contract.
If the answer is FHA, decide early: find a different buyer, use an assignment if the contract allows and the lender accepts it, or hold.
If you will hold, line up fix-and-flip or bridge financing that matches the hold period.
Write the financing type into the B–C contract so nobody is surprised.
Confirm everything with the title company and, for structural questions, a real estate attorney.

Key takeaways

Under 24 CFR 203.37a, resales 90 days or less after the seller's acquisition are not eligible for FHA-insured financing.
On a double close you are the seller, and you acquired the property that day.
Cash and many private-loan buyers fit a same-day resale; FHA buyers generally do not.
Assignments may avoid the timing issue, but confirm with the buyer's lender.
If the best buyer is FHA, the plan becomes a hold with appropriate financing.

Choosing the right exit

If your best buyer is paying cash, a same-day double close may fit. If not, tell Axelrad about the deal and the team can talk through transactional, bridge or fix-and-flip options for the timeline you actually have. Start with the transactional funding page.
