- Homestead exemption
- Massachusetts has no broad, automatic, statewide ad-valorem homestead property tax exemption like FL or LA. Instead, under M.G.L. c. 59, § 5C, individual cities and towns may OPTIONALLY adopt a local 'residential exemption' that shifts a larger share of the tax burden from owner-occupied homes to non-owner-occupied and commercial property; most Massachusetts municipalities have not adopted it, but several major cities have, including Boston (saved qualifying homeowners up to $4,353.74 in the most recent fiscal year measured), Cambridge, and Somerville. Where adopted, owners must occupy the property as their primary residence as of January 1 and file an application by the town's deadline (e.g. April 1 for the following fiscal year in Boston); only one property per owner qualifies. Separately, Massachusetts's 'Declaration of Homestead' (M.G.L. c. 188) is an unrelated creditor-protection filing, not a property tax benefit, and is not reflected in this field.
First-time buyer / down payment assistance programs
- MassHousing Mortgage
MassHousing (the state's affordable-housing finance agency) offers 30-year fixed-rate first mortgages (conventional and FHA) through 80+ participating lenders statewide, with more flexible income and credit requirements than typical conventional loans; can be paired with MassHousing's own down payment assistance. A 'Purchase and Renovation' variant finances a purchase and renovation costs in a single loan. Minimum credit scores generally range 640-700 depending on loan type, property type, and loan-to-value ratio.
- MassHousing Down Payment Assistance (DPA)
Up to $30,000 in down payment assistance, structured as a second loan and available statewide, paired with a MassHousing first mortgage. Three repayment structures: (1) 0%-interest deferred loan up to $30,000, repaid at sale/refinance/payoff; (2) 15-year amortizing loan at 2% APR, max $25,000; (3) 15-year amortizing loan at 3% APR, max $25,000.
