I have a seller who is in the process of being foreclosed. 1st $140k VA 2nd $25k conventional rehab 8k Appraisd value $205k The homeowner wants to sell the house for $170k. I want to put him under contract for asking price, however my questions are how do I deal with fha on 1st. Can loan be assumed in this case? I know that there is a new law concerning flipping on fha's. Can you please advise me on how to draw contract to protect me and him. I want to assign the contract to an investor.
