Yes, possible... but not easy. To get a loan on a property in need of substantial repairs, there are only a few loan products out there, and now they are even tougher to qualify for. The Buyer has an extra burden of proof that they will and can improve the property to it's potential value, and the property has to appraise at the "As Is" value. In today's economy, very, very few conforming lenders will even consider that kind of paper - even with perfect credit and 20-30% down. There are non-conforming lenders out there, or portfolio lenders, but the rates are typically high. In reality, your buyer needs to be committed to the long haul, your lender has to be willing to do the work, and the seller...well, the seller just needs to be patient.
I would recommend avoiding the scenario unless you have all of your ducks in a row before even starting the process. Find a lender willing to do it. Then prepare your buyer for a rough process that could end with them losing the inspection and the appraisal money.
Cash is king. Lot's of luck to you.
