It is possible that your condo will qualify for FHA financing under the new guidelines released in September, 2012 by FHA. When I know the address of a property I can learn whether or not it will meet FHA guidelines for financing. The entire condo association must be FHA approved. If I can do anything to help you to sell your condo please contact me at 937-610-7687, Coldwell Banker Heritage Realtors. Even if it isn't FHA approved, there are some conventional loans which don't require 20% down.
See the following:
"Greater numbers of condominiums now qualify for mortgage financing insured by the Federal Housing Administration. That's because this month the U.S. Department of Housing and Urban Development, which oversees the FHA, loosened its requirements for association approval."
