If you are looking for seller funded down payment assistance it is about to disappear. See the article I am linking to here. Yesterday, the bill passed the house and the senate, the president is expected to sign the bill into law - SOON. I believe that the programs will be in place through 9/30, but since it's not final, I am not certain.
Good news, however, there are still other options - like grants based on your job, income level, etc. and there is an FHA VHDA plus loan which can still get you in no money down. If you don't have an agent or lender, call me. I am right here in Leesburg and I have a fabulous lender who knows these programs inside and out. http://www.VickyChrisner.com
