Your are going to have to review the specific terms of your offer to determine if you are eligible for a return of your deposit. Foreclosures are often exempt from disclosure rules and this could include HOA docs. The secondary issue would be were the docs delivered and signed for and the request for cancellation received within the 5 days after receipt.
Did you or your agent notify HUD youwere declaring the contract.."Null & Void" with-in the 5 days??
