To locate FHA lenders and their registered branches go to https://www.hud.gov/program_offices/housing/sfh/lender/lenderlist which allows you create a list of FHA approved lenders in your area. Please read the file attached to the help screen for more details on how to use this web page.
The lender locator is not an all-inclusive list of lenders currently participating in a particular program such as HECM, Title 1, etc. Please contact your lender to confirm their participation in each specific HUD/FHA program.
You can also find lenders in your area using your local telephone directory under the heading 'Mortgages'.
