Any restriction on flip lending on a HUD Home?

[Chris D.]

Hi:

Does anyone know if there are restrictions on how much of a loan a rehabber can get when purchasing a HUD home? I funded a FNMA foreclosure a few months ago. The contract stated that the rehabber couldn't obtain a loan that was only 15K above the sale price of the home they bought. The purchaser/borrower had to get the seller to sign an addendum authorizing a higher loan amount (over 100K). Is there a similar restriction on a HUD foreclosure property. I know they must be held for at least 90 days.

Any help or advice is appreciated.
