FHA Loan Question Regarding 75%

[Mark Malevskis]

Hello all, 

I had a question about the FHA 3.5% down payment loan. To my understanding, for instance if it is a 4 unit property, to qualify for this loan, 3 of the 4 units must cover the entire mortgage.

Does anyone know the exact requirements in terms of what 3 of the 4 units have to cover. Is it just mortgage, or PITI (principal, interest, taxes, and insurance)?

As far as I understand my income, does not really matter, if 3 units cannot cover the mortgage. 

I am a little confused on this, any clarification would be great. 

Thank you, 

Mark
