How the FHA self-sufficiency calculator works

FHA’s self-sufficiency test applies to a triplex or fourplex bought with an FHA loan. It counts 75% of the market rent for every unit, the one you’ll live in included, and that has to cover the full monthly payment. The sample fourplex passes with $574 a month to spare.

How is FHA’s self-sufficiency test worked out?

  1. Add up what an appraiser says each unit would rent for, your own unit included.
  2. Take off the appraiser’s estimate for vacancies and maintenance, or 25% if that is more.
  3. Compare what is left with the full monthly payment. If the rent covers it, the building passes.

On the sample, four units at $1,575 come to $6,300 a month. Less 25%, FHA counts $4,725. The full payment is $4,151, so the building passes with $574 to spare.

What does FHA count as the payment?

Principal and interest, property tax, insurance, FHA’s monthly mortgage insurance, and any association dues.

The sample puts 3.5% down, $17,465, on $499,000. FHA charges an upfront fee of 1.75% of the loan, which can be added to it, so the loan is $489,962 and principal and interest are $3,097 at 6.5% over 30 years. Tax and insurance add $833. The monthly mortgage insurance is about $221: 0.55% a year of the loan before the upfront fee.

The rule is in HUD’s Handbook 4000.1, and the mortgage insurance rates are in Mortgagee Letter 2023-05.

What can you do if a building fails?

The same fourplex at $1,300 a unit fails. FHA counts $3,900 against the same $4,151 payment, which leaves it $251 a month short. Three things would pass it:

  • Higher market rent. It passes at $1,384 a unit.
  • More money down. It passes with $51,178 down, 10.3% of the price.
  • A lower price. It passes at $461,257 with 3.5% down.

Does a duplex take this test?

No. FHA applies it to three- and four-unit buildings only. Passing it does not replace the lender’s check of your own income and debts.
