FHA's rules for buying 2 to 4 units
-
FHA insures loans on 1 to 4 unit properties that are the owner's principal residence. For 2 to 4 units, the lender must obtain form HUD-92561.
“Except as otherwise stated in this Handbook 4000.1, FHA’s Single Family programs are limited to one- to four-family Properties that are owner-occupied Principal Residences.”
-
At least one borrower must move into the property within 60 days of signing and intend to live there at least 1 year.
“At least one Borrower must occupy the Property within 60 Days of signing the security instrument and intend to continue occupancy for at least one year.”
-
The FHA loan may not pass your area's limit, which rises with the number of units. The limit is checked against the loan before the financed upfront mortgage insurance premium (UFMIP) is added.
“A Mortgage that is to be insured by FHA cannot exceed the Nationwide Mortgage Limits. … restrictions to mortgage amounts and LTVs are based upon the amount prior to the financing of the Upfront Mortgage Insurance Premium (UFMIP) (Base Loan Amount).”
Handbook 4000.1, II.A.2.a and II.A.2.a.iii, p. 177; p. 178 ↗
-
The units' rent can count as income. With no rental history, the lender uses 75% of the lesser of the appraiser's rent or the lease rent. It may not subtract it from your payment.
“the Mortgagee must use 75 percent of the lesser of: fair market rent reported by the Appraiser; or the rent reflected in the lease or other rental agreement.”
-
With 3 or 4 units, the payment (principal, interest, taxes and insurance) divided by the net rent of all units, yours included, may not pass 100%. Net rent is the appraiser's rent less the appraiser's vacancy and maintenance estimate or 25%, whichever is greater.
“The PITI divided by the monthly Net Self-Sufficiency Rental Income may not exceed 100 percent for three- to four-unit Properties. … Net Self-Sufficiency Rental Income is calculated by using the Appraiser’s estimate of fair market rent from all units, including the unit the Borrower chooses for occupancy, and subtracting the greater of the Appraiser’s estimate for vacancies and maintenance, or 25 percent of the fair market rent.”
-
With 3 or 4 units, the lender must verify reserves of 3 months of payments after closing. With manual underwriting, it asks for 1 month for 1 or 2 units.
“The Mortgagee must verify and document Reserves equivalent to three months’ PITI after closing for three- to four-unit Properties.”
