The U.S Department of Housing and Urban Development (HUD), federal housing program financially helps moderate or low-income families with disabilities to rent or buy a home. The goal of this program is for people with limited economy to be able to afford to rent or buy a home. Section 8 offers subsidies for both renters and home owners. Approved recipients will be granted monthly home ownership assistance payments to help cover mortgage payments.
The only one I know of is VA loans. If you have a VA certificate of Eligibility and receive VA related disability benefits, you do not have to pay a funding fee. This includes all disabled vets receiving VA benefits.
