Can I sell my house with an ADU or my duplex with a tenant living there?
Yes. A lease normally stays in force when your property sells, and the buyer takes it over, unless the lease itself says otherwise. The lease dates decide who can buy: a buyer who will live there needs one unit they can move into soon after closing.
WHAT MOST PEOPLE ARE NEVER TOLD
Fannie Mae and FHA home loans give a buyer 60 days after closing to move in. One unit free by then adds buyers who will live there. With every unit leased past that, your buyers are mostly investors.
Your property keeps both kinds of buyer, the investor and the person who will live there, when:
- One unit is empty, or its lease or notice period ends before the buyer must move in.
- The other units are rented at market on signed leases you can hand over, with proof the rent is being paid.
If you live in the house and rent the ADU, the buyer moves into the house and the ADU's lease carries over. Signed leases also help your buyer. Their lender can usually count 75 percent of that rent as income, with conditions that differ by loan. A lease shows the buyer the likely figure before they offer, and the appraiser then has to back it up.
On an FHA loan the lender uses the lower of two rents: the lease, or the appraiser's market figure. So a lease near market rent lets your buyer borrow more than one far under it.
GOOD TO KNOW
Before you promise a buyer an empty unit, have a local attorney check your leases and notice period, since month-to-month notice rules vary by state and city. A tenant on a lease usually keeps the unit until it ends, and a unit held empty earns no rent while you wait.
Yours is a little different. They all are.
