FHA & VA loans allow a maximum 6 % seller assist. Down payment amount is not a factor, Owner occupancy only.
Fannie Mae, Freddie Mac and most Jumbo programs allow the following for Owner Occupancy
3% for 0 - 9.99% downpayment
6% for 10-24.99% down payment
9% for 25% or higher down payment
Investment properties are usually limited to a 2% seller assist
Hope this helps
Seller allowable participation in Buyer's closing costs is not dictated by the state but rather by the buyer's loan program
Most FNMA (conventional) loan programs allow seller to pay at closing up to 3% of the purchase price toward buyer's closing costs.
FHA an VA loan programs allow seller to pay up to 6% of the purchase price toward buyer's closing costs.
Best of luck
