In my opinion, Home Path really isn't that great of "deal" unless you plan on buying the home and using it as a rental property.
With your credit scores, a conventional loan should give you the lowest overall monthly payment with as little as 5% down.
The amount of closing costs that are covered by the seller will depend on the seller and what the loan program allows. For example, an FHA loan will allow the sellers to pay up to 6% of the sales price in closing costs but a conventional loan will only allow up to 3%.
