I am a buyer of a short sale, got approval from bank after 5 months, my offer is well over listed price. 2 weeks before closing bank denied approval because of fraud investigation related to listing agent living in the house. Listing agent claims he was helping seller as caretaker of the house (seller moved to diff state) while his own house was being remodeled and gave money to the seller to help them out. What are my options? I don't have the house after waiting 5 months, housing market has changed in 5 months and now I cannot find a similar house (I have specific requirements of a house due to medical condition of people in my family).
