The prefilled price, tax percentage, and interest rate are illustrative inputs, not verified Massachusetts averages or lender quotes. Replace them with the property's price, a local tax estimate, an insurance quote, and your lender's rate.
Proposition 2½ limits a municipal levy
Massachusetts Proposition 2½ limits the property-tax revenue a municipality can raise. It does not make the calculator's example tax percentage a legal rate for an individual home. Changes in assessed values and local tax decisions still matter.
For your estimate: Ask the city or town for the parcel's estimated bill and any applicable residential exemption. Do not assume an individual bill increases by exactly the percentage in the law's name.

MassHousing's MI Plus benefit can help eligible borrowers with principal and interest payments during qualifying unemployment. It accompanies MassHousing mortgage insurance and is not the homeowners policy that covers damage to the building.
For your estimate: Keep the quoted homeowners premium in Annual Home Insurance ($). Ask the lender separately about mortgage insurance, MI Plus eligibility and any payments or costs outside its benefit.

Using local estimates in this tool
The tax field multiplies the home's price by a percentage. If your assessor estimates an annual tax bill, divide that bill by the entered home price and multiply by 100. Do not enter an assessment ratio or millage directly. For example, an illustrative $4,800 annual bill on a $400,000 price corresponds to 1.2%; these are not local averages.
This payment includes principal, interest, property tax and home insurance. Budget mortgage insurance, HOA dues, maintenance and closing costs separately.
Official resources and next steps
HUD housing and homeownership resources for Massachusetts provides further counseling and housing contacts.
For FHA financing, use HUD's county and unit-count lookup. Select Massachusetts, the property's county, the calendar year, and the number of units. The 2026 national one-unit floor of $541,287 is a baseline, not a determination of the limit for every county in Massachusetts.

How to Use This Mortgage Calculator in Massachusetts
Enter the price of the property you are considering in Massachusetts, then adjust the down payment and rate. The payment combines principal, interest, property tax, and insurance. It does not include HOA dues, maintenance, or mortgage insurance.
For example, at the illustrative price of $598,000 and 7% down, the base loan is $556,140. These are calculation examples, not a statement about prices or typical buyers in Massachusetts.
Compare the same home under different rates and down payments. A lower monthly payment from a longer term can still mean more lifetime interest. Confirm taxes and insurance for the property before relying on the estimate.
