Why buyers look at multi-families in Chelsea
Chelsea has many 2-family and 3-family homes. Many are classic triple-deckers, with one apartment on each floor. Others are side-by-side or up-and-down 2-families. You will also see some larger buildings and condos made from older houses.
The idea is simple. You live in one unit. You rent the others. The rent helps pay the mortgage, taxes and insurance. Over time, you build equity in a building that can keep earning income.
- 2-family: one unit for you, one rental.
- 3-family / triple-decker: one unit for you, two rentals.
- 4-family: still financed as a home loan when you live in one unit.
Owner-occupied loans: FHA, conventional and state programs
When you live in the building, you can use home loans with smaller down payments than investor loans.
- FHA: 3.5% down with a credit score of 580 or higher, on 1–4 unit homes you live in.
- Conventional: Fannie Mae allows as little as 5% down on an owner-occupied 2–4 unit home.
- ONE Mortgage: a state program for first-time buyers with 3% down, or 5% for a 3-family.
- MassHousing: loans for 1–4 unit homes, plus down payment help for first-time buyers. See MassHousing down payment assistance.
For 2026, the FHA and conforming loan limit in Suffolk County is $1,232,250 for a 2-family and $1,489,500 for a 3-family. Your lender confirms which program fits you.
Can the rent cover the mortgage?
Sometimes the rents cover a big part of the payment. Sometimes they do not. It depends on the price, your down payment, the interest rate and the current rents. We run the numbers before you make an offer.
- Add up the real rents from the leases, not the hoped-for rents.
- Subtract taxes, insurance, water and sewer, repairs and a little for empty months.
- Compare what is left to the monthly mortgage payment.
Lenders can often count part of the rent from the other units to help you qualify. Each loan program has its own rules, so ask your lender how they count it.
Owner-occupants in Chelsea may also qualify for the city's residential exemption, which lowers the taxable value of the home you live in.
Massachusetts rules to know before you buy
- Lead paint: if the building was built before 1978, then before you sign the Purchase and Sale Agreement, the seller must give you the Property Transfer Lead Paint Notification. If a child under 6 lives there, the owner has 90 days after taking title to delead or reach interim control.
- Tenants: leases and security deposits usually transfer to you. Ask for copies of every lease and deposit record.
- Inspection: have the whole building inspected, including each unit, the heating systems and the roof.
