House prices and costs in Boston, MA

How house prices moved across 30 Boston ZIP codes, what buyers here borrowed and paid, what's new and how buying works in Massachusetts. Public data, with sources and dates. Past change, not a forecast.

Boston, MA house prices +4.6% in the year to 2026 Q2 (FHFA, purchases)

7.03% is Freddie Mac's average 30-year fixed rate for the week of Sep 24, 2026, for buyers with 20% down and excellent credit. It isn't an offer or an APR.

How house prices moved in Boston, 2022–2025

Of 12 ZIPs with enough data, 10 rose 7% or more, 0 fell 7% or more and 2 moved less (no clear change). Past rankings are a weak guide: of the ZIPs in their city's top 3 for 2019–2022, 25 of 134 (about 1 in 5) were top 3 again for 2022–2025; chance alone would give about 21. Past change, not a forecast.

Research summary · not legal advice

How buying works in Massachusetts

The usual steps, deadlines and closing costs for a purchase in Boston, from state law, standard contract forms and local custom. Contracts can change any of it. Homiy is a prototype: it isn't a licensed brokerage in Massachusetts and offers no services here.

Who runs the closing
Attorneys run the closing. A lawyer must conduct it. Typical time from contract to keys: about 45 days.
The contract
Your signed offer becomes a binding contract once the seller accepts it.
Details

Accepted written offer followed by attorney-negotiated Purchase and Sale Agreement (P&S)

Buyer agreement
Written Massachusetts buyer representation agreement and agency disclosure, signed before touring.
Details

Homiy's prototype requires a written agreement before a represented tour. NAR's rule binds participating MLS brokers; do not describe it as a universal state law. Compensation is negotiable and total brokerage pay cannot exceed the agreement.

Source: NAR: written buyer agreements before touring (MLS participation rule, not a universal state statute) (reviewed 2026-09-27)

Second signing
About 14 days after the accepted offer (a sample target); the deposit comes to about 5% of the price.
Details

The accepted offer can already bind; P&S commonly follows inspection, with total escrow deposit topped up to about 5%, not an additional 5%. Fourteen days is a sample target. Attorneys negotiate P&S and participate substantively in closing (REBA v. NREIS).

Inspection
About 10 days for inspections.
Details

760 CMR74 protects inspection rights for nonexempt transactions after 2025-10-15: seller may not condition acceptance on waiver or accept an offer indicating intended waiver; required separate disclosure and reasonable inspection time. Do not offer an inspection-waiver strategy. 10 calendar days is a negotiable sample planning period, not a statutory deadline.

Earnest money
0.1–0.5% of the price, paid when the contract is signed, held by: Listing broker escrow or attorney trust account.
Details

Small initial offer deposit is negotiated (often a fixed dollar sum); 0.1–0.5% is a sample range, not market statistics. Top up, do not double-count, the roughly 5% total at P&S.

Seller's disclosure
Not generally required (No general mandatory condition form; lead-paint, septic/Title 5 and inspection-right disclosures as applicable).
Details

No generic statutory seller-condition cooling-off period. Do not confuse optional condition statement with mandatory lead, septic and 760 CMR74 disclosures; fraud and broker disclosure duties still apply.

Source: Massachusetts real estate brokers and salespersons consumer fact sheet (reviewed 2026-09-27)

Loan and appraisal
Loan contingency: 30 days (set in the contract).
Details

30-day financing period and the typical closing time are sample planning assumptions, not measured averages or legal rights. Financing and appraisal protection require the signed form/addenda; an appraisal shortfall is not automatically protected. Tie the actual commitment date to the offer/P&S; extensions require buyer and seller approval.

Title insurance
The buyer customarily pays for the owner's policy.
Details

Payer is a negotiable local custom, not a mandatory charge; obtain a title quote and follow the signed allocation. Filed insurer/rating-bureau rates are not a state-promulgated price.

Property tax for a new owner
Your property tax follows the county's assessed market value. About 1.2% of the price a year is our planning figure for Boston; your bill can differ.
Details

Use the assessor's current taxable value, assessment ratio and parcel tax district. Price is only a planning proxy; exemptions, revaluations, credits and special assessments are not inherited automatically.

FY2026 Boston residential rate $12.40/$1,000 assessed value =1.24%, applied to assessor value (price proxy), before the owner-occupant residential exemption and other relief. Eligibility/reference dates can delay a new buyer's exemption; use actual assessment. Not a statewide rate. HOA range and lender-title percentage are SAMPLE planning inputs, not observed means.

Agent credits to the buyer
Massachusetts allows an agent to credit part of their pay to the buyer, with the lender's approval.
Details

MGL112 §§87AAA(e),87QQ distinguish principals from people requiring brokerage licenses. The Board executive director's published explanation expressly permits gifts/inducements to buyers and sellers, not unlicensed people doing brokerage. Disclose the agreed credit and obtain lender approval; the historical interpretation is not approval of this prototype.

Methodology

How we measure, and what it isn't

Past change, not a forecast. These figures describe the past from public data; they don't tell you where prices go next.

House prices by ZIP, and the rankings

FHFA's experimental ZIP house price index: houses with Fannie Mae or Freddie Mac loans, from sales and refinance appraisals. Condos, co-ops and multi-unit buildings aren't in it. It's built from repeat sales and refinance appraisals of the same homes, not average sale prices, and FHFA publishes no margin of error for it. We rank ZIPs by the change over the last 3 years, only where FHFA published the index in every one of them, and only ZIPs with 5,000+ residents and 1,000+ owner-occupied homes. A change smaller than 7% either way is “no clear change”: in our 50 cities, the index's own year-to-year swings suggest sampling alone can move a three-year change about that much. A ZIP whose index rose 7% or more in one year and fell as much in another is left out as too jumpy. We show rises and falls, each year's change, and the city's and metro's figures for the same years. Past rankings are a weak guide: of the ZIPs in their city's top 3 for 2019–2022, 25 of 134 (about 1 in 5) were top 3 again for 2022–2025; chance alone would give about 21. Many ZIPs, especially dense ones, have no index.

City and metro price figures

City: the resident-weighted average of its ZIPs that have an index (the ZIP card says when that's only part of the city). Metro: FHFA's all-transactions index over the same calendar years, the ZIPs' method; the metro card also shows FHFA's purchase-only index for the latest quarter against a year and five years earlier. Where FHFA splits a metro into divisions (New York, Miami, Detroit and others), the division's index, named where it's shown. Jobs, permits and population always cover the whole metro.

Payment ÷ income

Monthly housing payment (est.) on a house at the ZIP's median value: 20% down · 30-year fixed at 7.03% (Freddie Mac average) · 360 monthly loan payments · APR not calculated (it depends on the lender's fees) · includes principal and interest, property tax, home insurance and any HOA dues, plus mortgage insurance below 20% down. Property tax uses Boston's rule for a new buyer (about 1.2% of the price a year, our planning figure); insurance is a typical premium. Not included: upkeep, utilities, flood insurance, special assessments. Divided by a month of the ZIP's median household income. The Census reports values over $2 million and incomes over $250,000 only as “or more”, so those shares are bounds (“at least”, “at most”). Left out where 50% or more of owner-occupied homes are in buildings with 5+ units: their HOA dues or co-op charges aren't in the payment. It combines two estimates, so no margin is computed. 7.03% is Freddie Mac's average 30-year fixed rate for the week of Sep 24, 2026, for buyers with 20% down and excellent credit. It isn't an offer or an APR.

Census figures and margins of error

American Community Survey 5-year estimates, 2020–2024: the median value owners report for their homes (it lags sale prices; co-op owners report the value of their shares), median rent with utilities, median household income, residents, and the property tax and monthly costs owners report. Each comes with its 90% margin of error (±). Figures whose margin is 20–49% of the estimate are marked “less reliable” and left out of rankings and tags; figures with wider margins aren't shown. A population change (from 2015–2019) is shown only when it passes the Census Bureau's 90% significance test; otherwise it says “no clear change”. Boston's own figures come from the Census's estimates for the city itself where published; otherwise they blend its ZIPs (no margin computed). Lists leave out ZIPs with fewer than 1,000 residents.

Tags

Lower home values:
The median value owners report is in the lowest quarter of the city's ZIPs (Census ACS). Less reliable estimates and ZIPs where most owners live in condos or co-ops aren't compared.
Population grew:
Residents rose 5% or more between the two latest five-year Census surveys, by more than the margin of error.
Mostly condos or co-ops:
Half or more of owner-occupied homes are in buildings with 5 or more units. Values there leave out HOA dues and co-op charges, so they aren't ranked.
New rail nearby:
A rail station opened within about a mile in 2023–2026.

“New rail nearby” uses our dated news pins: a ZIP whose center is within 1,600 m of a station that opened, plus the ZIP the station sits in. No tag describes price momentum.

Hazards and flood insurance

FEMA's National Risk Index rates each county's expected yearly losses from each hazard against all U.S. counties; we show those Expected Annual Loss ratings for every county the city lies in, without FEMA's social-vulnerability adjustments. They describe counties, not homes. Flood insurance counts are policies and claims in the federal program (NFIP) only. Check an address's flood zone on FEMA's flood map.

What buyers borrowed and paid

Public HMDA loan records: home-purchase first liens on owner-occupied 1–4 unit homes in the city (the card names the area covered), with the number of loans behind each figure. Loans that closed, not offers or quotes.

Neutral by design

We describe prices, payments, population counts, construction and rail lines. We don't describe places by who lives there, schools or crime, and we don't call areas “up-and-coming”, “transitional” or “safe”. Choose where to live for your own reasons.
