FHA and multi family

[Kimberly Hawkins]

Hi, I'm interested in buying multi family properties using an FHA loan to house hack. My question is, on FHA loans do all properties in the multi family need to meet the standard living requirement set forth by FHA? Or only 1?

The scenario:

Three door property, only 1 of which meets FHA requirements for safety. Will I still be eligible to buy this property given that I will live in the acceptable unit? The other 2 units need rehab before being rentable.

Thank you!
