I believe the only possible loan program at this time with no downpayment is a VA loan (Veterans). FHA loans are 3.5% minimum downpayment. Closings cost can vary from 1.5% to 2.0% of the purchase price. It will depend on a few variables, such as points (1 point is 1% of loan amount) paid on the loan. Talk with a local mortgage broker and they should be able to produce estimated cost sheets outlining estimated closing costs for different purchase prices.
