What Affects a Dorchester Loan
Third Unit Changes Rules
On FHA, a three-family has to pass a rent test that a two-family never faces.
What the rent test means
On an FHA loan for a three- or four-unit home, the building’s projected rent has to cover the full monthly payment. A two-family skips this test. If you’re weighing both, we’ll run each before you write an offer.
Small Associations
57% of Dorchester condos are in a two-to-four-unit association. On a conventional loan, that size skips the full project review. FHA’s single-unit route needs five units or more.
Why this matters for your down payment
If you planned on FHA for a unit in a three-unit building, the loan may not be available on that building. A conventional loan with a low down payment often is. We check the building before you’re under agreement.
Tax Bill Cut
Boston’s residential exemption took $4,353.74 off a fiscal 2026 owner-occupier bill. It doesn’t transfer from the seller. You apply, by April 1, 2027 for fiscal 2027.
Why your quote may not match the listing
The listing usually shows the seller’s tax with their exemption. Until yours is approved, the escrow on your loan is set at the full bill. We’ll show you both numbers.

Dorchester Flood Zones
of Dorchester’s homes and condos touch a FEMA high-risk flood zone. Most of the neighborhood is Zone X, minimal hazard.
In a high-risk zone the lender requires flood insurance, added to your monthly payment. Pan the map to your street, or send us the address.

Dorchester Loan Details
City Water and Sewer
The Boston Water and Sewer Commission serves the city, so a typical Dorchester purchase skips the well test and septic inspection lenders ask for in rural towns.
No USDA Zero-Down
USDA's 100% financing covers rural addresses only, and Boston is outside them. A three-family with ONE+Boston at 5% down is the closest thing here.
No Override Votes
Boston has never voted on a Prop 2½ override. The CPA adds 1% after the first $100,000 of value, $18.46 a year in the City's own example.
| Flood zones | 1.96% of homes and condos, 0.42% of three-deckers. Map above. |
|---|---|
| Property tax | $12.40 per $1,000 (fiscal 2026), before the residential exemption. |
| MBTA Communities zoning | Doesn't apply. Boston zones under its own law, outside the state act that carries the rule. |
| Commute downtown | Red Line, 9 to 17 minutes to Downtown Crossing. Fairmount Line, 16 to 19 to South Station. |
| Deeds recorded at | Suffolk Registry of Deeds |
