Good morning, Joanne,
There is a 203(b) loan, financing the purchase or refinance of a home, as long as the property in question is FHA-approved, affixed on an 8-point foundation, on land you own and taxed as real estate.
If you're thinking 203(k) for rehabbing or renovating, here's what HUD's training for lenders says about eligible properties:
• 1- to 4-family dwellings
• Manufactured homes built after 1978
• Mixed use
So, yes, you can do it. Finding lenders capable of originating this loan may be more difficult. HUD does maintain a list of approved lenders.
Search here and check the box for 203(k) rehab mortgage at the bottom: https://www.hud.gov/program_offices/housing/sfh/lender/lenderlist
Good luck and thank you for writing.
