Boston and Inner-Core Mortgage Hub: Residential Exemptions, Condos and High-Balance Caps
Updated October 2026
A Boston condo with a lower asking price can still produce a higher monthly payment than a nearby home once association dues, property taxes and insurance enter the calculation. Saltbox & Seam starts inner-core comparisons with the complete housing payment, then checks whether the property and loan qualify for the financing you expect.
Match the loan to the county and building
The 2026 baseline conforming limit is $832,750, but Boston buyers should use Suffolk County’s applicable limit rather than assume the baseline controls. Massachusetts high-cost markets can support substantially larger conforming balances, with the upper ceiling reaching $1,249,125. Check the county and unit count through FHFA Loan Limits before labeling a purchase jumbo.
A high-balance conforming mortgage is not automatically priced like a baseline loan. Compare rates, points, mortgage insurance and required reserves at the actual borrowing amount.
For a condominium, underwriting also reaches beyond your credit profile:
- Association budgets, reserve funding and master insurance affect project eligibility.
- Pending litigation, structural repairs and special assessments can interrupt approval.
- Commercial space and short-term rental activity may require additional review.
- Parking and storage rights should match the deed and purchase documents.
Calculate the owner-occupied tax bill
Boston’s residential exemption can reduce taxable value for qualifying principal residences. Nearby Chelsea and Everett also offer residential exemptions, but eligibility dates and application procedures differ. Do not assume a seller’s exemption transfers to your first tax bill.
Proposition 2.5 limits municipal levy growth, not each homeowner’s annual tax increase. Revaluation, new growth and voter-approved measures can change the outcome. A Community Preservation Act surcharge, where adopted, adds another item to examine. Start with the actual municipal assessment and exemption status, using the Massachusetts Department of Revenue Division of Local Services for the statewide framework.
Build the offer around verified costs
Massachusetts purchases commonly move from an Offer to Purchase to a more detailed Purchase & Sale agreement. Attorney review, mortgage contingency dates and condo-document delivery should fit that two-contract sequence.
Use the monthly payment calculator with realistic taxes, dues and insurance, then compare cash requirements in the closing cost estimator. Request association documents before committing to a tight financing deadline. For small converted buildings, continue with the Boston neighborhood condo guide, where triple-decker ownership and rental restrictions become central underwriting questions.

Editorial Methodology & Primary Sources
Verification date: Not recorded; check the primary source and lender timestamp before relying on an estimate.
Rate comparisons use participating lender feeds, not a whole-market survey or guaranteed offers. Freddie Mac PMMS is a market benchmark, not a personalized quote. Calculator models rely on published regulatory formulas and disclosed assumptions rather than fabricated first-person loan testing.
Monthly principal and interest use the amortization formula P × r / (1 − (1 + r)−n), where r is the monthly note rate and n is the number of payments; at zero interest use P / n. PITI adds monthly property taxes and homeowners insurance; PMI is separate. APR includes applicable finance charges under Regulation Z and is not the note rate used for payments. Compare lender Loan Estimates for actual APR and fees.

- U.S. Department of Veterans Affairs (VA) — VA loan eligibility and benefits.
- Freddie Mac Primary Mortgage Market Survey (PMMS) — published rate benchmarks.

The payment snapshot uses illustrative annual taxes of 1% of home price, $1,200 insurance and 0.5% PMI below 20% down, not verified local quotes. Other calculators disclose their inputs and assumptions. Published guidance and lender feeds may change independently; confirm current program rules, taxes and offers before a decision.
