The best way to approach the sellers of any situation is full disclosure with an option to purchase agreement ( standard flex agreement) which detail :
1) the option is assignable to end buyer ( for fee).
2) if buyer / optionee ( I) is not able to find an end buyer the agreement will be null.
3) Seller has the right to cancel or find his own buyer.
4) buyer/optionee is not real estate agent and is not representing anyone in this deal.
NO LIE , NO ACT AS IF YOU ARE CASH INVESTOR, FULL DISCLOSURE, NO PURCHASE AGREEMENT WITH SELLER ( unless if you solid buyer but again you could assign your option agreement and collect the assignment fee. there is no need to get in signing purchase agreement that you fully aware that you will not close on personally).
Assigning your right to purchase your end buyer, and have him sign with the seller the Real estate purchase Agreement, after he sign your Fee assignment agreement and place refundable part /full of FEE.
there is no law broken here, you are not acting as realtor , not lying. what you are doing is helping someone who was unable to sell via realtor or himself, someone who will lose everything if the house is lost in auction...., so finding a buyer to cash him out, saving credit is not a bad thing BUT FULL DISCLOSURE-NO PROMISE.....
these type of homes are in condition and distressed situation that realtors can not help because they are not financeable, not enough equity to pay their commission, not in move in condition for the retail buyers
thank you
