Government grants and Down Payment Assistance are available from many agencies. Some are provided by the Federal Government while other are provided by states, counties or cities.
Grants provide money to pay, or help pay, for your down payment and/or closing costs.
Little or No Down Payment options provide you with a way to finance your down payment and sometimes even closing costs if the seller does not pay them all. These are great options if grants aren't available or you don't qualify for a grant.
