In Massachusetts, a signed offer is a binding contract — which means the checking has to happen before you sign it, not in the ten days after.

Massachusetts home sales run on two documents: the offer (formally, the Offer to Purchase), signed first, and the longer purchase and sale agreement that follows roughly ten to fourteen days later. Buyers routinely treat the offer as a handshake — a way to reserve the house while the real decision happens later. Massachusetts law disagrees. In McCarthy v. Tobin (1999), the Supreme Judicial Court held that a signed standard-form offer was a binding contract, enforceable against the party who tried to walk away — even though both sides expected to sign a purchase and sale agreement afterward.
Layer the market on top of that. A competitive Greater Boston listing goes from first open house to offer deadline in three to five days. For years, offers were won by shortening or waiving contingencies — nationally, roughly one in five successful buyers has waived the inspection contingency outright in recent years, per the National Association of Realtors' monthly confidence survey. Massachusetts pushed back: since October 15, 2025, under 760 CMR 74.00, a seller can no longer condition acceptance of an offer on waiving the inspection (what that rule does and does not do). But the inspection that regulation protects still happens after acceptance, and still covers only physical condition. The structural mismatch stands: the moment of maximum legal and financial commitment is also the moment of minimum information — unless the information-gathering moves to before the offer.
Post-offer diligenceis the familiar kind: a home inspection inside a contingency window (typically up to ten days), attorney review at the purchase-and-sale stage, the lender's appraisal, the title exam before closing. All of it happens after the price is agreed and the deposit is on the table.
Pre-offer diligence is everything a buyer can learn before signing anything: permit history, deed and easements, assessor records, flood maps, zoning, condo finances, septic-versus-sewer status. Nearly all of it sits in public records — the constraint is time and knowing where to look, not access.
The standard cast of a Massachusetts transaction covers less than buyers assume, and almost none of it before the offer:
Put it in a table and the gap is hard to miss — several of the most expensive questions have no default owner at all:
| Question | Who checks it by default | When |
|---|---|---|
| Physical condition (roof, systems, structure) | Home inspector | After the accepted offer — a right 760 CMR 74.00 now protects, but never before it |
| Title, liens, encumbrances | Your attorney and the title company | Purchase & sale through closing |
| Open permits and unpermitted work | Nobody | — (unless you or your agent pulls the permit file) |
| Condo budget, reserves, litigation, special assessments | Your attorney, if the documents are requested in time | The compressed window between offer and purchase & sale |
| Flood zone and what insurance will actually cost | Nobody for the buyer — the lender checks only its own requirement | Screen before the offer, then get a carrier decision or binder early. See the Massachusetts buyer insurance checklist. |
| Zoning, nonconforming use, rebuild rights | Nobody | — |
| Assessment history, tax trajectory, betterments | Nobody | — |
The honest case for pre-offer diligence is not that every house hides a disaster — most don't. It is that the downside is severe, one-directional, and lands on exactly one person: you, after closing. In Clever Real Estate's 2025 national survey, 65% of buyers reported regrets about their purchase — 73% among first-time buyers — with underestimated costs and rushed decisions leading the list. The failure modes are not exotic; they are the same handful, over and over:
Against all of that, the cost of checking is a few hours in public records — or a report — before the offer deadline. The asymmetry is the argument: the check is cheap, reversible, and happens while you can still act on it; the miss is expensive, permanent, and discovered when your only options are bad ones.
Everyone else in the transaction gets paid when it closes. You are the only party whose interests are fully served by finding the problems first — which is why the checking, whoever performs it, has to happen on your side of the table and on your timeline.
The good news is that the highest-stakes questions are answerable from public records in the three to five days a listing is on the market:
Two framing points matter. First, since October 2025 Massachusetts law protects your right to a home inspection — under 760 CMR 74.00 a seller can no longer demand you waive it as the price of acceptance (the waiver rule in detail). Use that right. But notice what it protects: a condition inspection, after your offer is accepted. Every question in the table above that an inspection never covered is still yours to answer — and still only answerable before you sign. Second, this is not about killing deals. Most checks come back manageable, and that is the point: you either offer with confidence, or you price the problem into the offer with evidence in hand — instead of discovering it when the only remaining move is to absorb it.
Since the 2024 NAR settlement, every buyer relationship starts with a written agreement that spells out, conspicuously, what you will be paid. Buyers read that number and ask the obvious question. "I'll unlock doors and write the offer" does not answer it; a documented pre-offer diligence process does. A researched memo on the specific property — permit file, assessor mismatches, deed restrictions, flood status, condo financial red flags — is one of the few deliverables a buyer can hold in their hands before deciding to compete for a house, and it reframes your fee from the cost of access into the price of not buying the wrong property.
It is also risk management. Failure-to-disclose claims are perennially the top source of litigation against real estate agents, and the practical defense is the same in every jurisdiction: a written record showing what was checked, what was found, and that it was shared with the client — dated before the offer. A repeatable diligence process is E&O hygiene as much as it is client service.
Finally, it compounds. In a competitive market a serious buyer writes several offers before one sticks, so a per-property research process that takes you a full afternoon doesn't scale — and skipping it on the fourth offer, when everyone is exhausted and just wants to win, is precisely when the expensive miss happens. Survey data ties rushed decisions to buyer regret more strongly than almost any other factor; the agent's job in the final 72 hours before an offer deadline is to compress the research without skipping it.
Everything a buyer can learn about a property before signing an offer: building-permit history, deed restrictions and easements, assessor records, flood-zone status, zoning, condo budgets and reserves, and whether the property is on septic or sewer. Nearly all of it comes from public records — it is distinct from the post-offer steps (home inspection, attorney review, title exam) that only begin after the price is agreed and a deposit is down.
Generally yes. In McCarthy v. Tobin (1999), the Massachusetts Supreme Judicial Court held that a signed standard-form Offer to Purchase was an enforceable contract even though the parties expected to sign a purchase and sale agreement later. Your protection comes from the contingencies written into the offer — and in a competitive market those are exactly what buyers are pressured to shorten or waive.
No. A standard Massachusetts home inspection is a visual, non-invasive review of physical condition — roof, systems, structure — after your offer is accepted, and its scope is set by regulation (266 CMR 6.04). It does not include a permit search at the building department, a deed or title review, condo document analysis, flood-zone research, or zoning questions. Since October 15, 2025, 760 CMR 74.00 bars sellers from conditioning offer acceptance on an inspection waiver — a response to years in which roughly one in five successful buyers nationally waived the inspection, per NAR’s monthly member survey — but even that protected inspection begins only after your offer is accepted. See the waiver-ban guide for what the inspection legally does and does not cover.
Mostly no. Massachusetts follows caveat emptor for residential sales: there is no state-mandated seller disclosure form, and outside specific carve-outs (lead paint disclosure, the Title 5 septic inspection at transfer), a private seller generally has no duty to volunteer known defects. Real estate licensees must answer questions honestly and cannot misrepresent, but the burden of investigating rests on the buyer.
At minimum: the town’s permit file against the listing’s claimed improvements, the assessor record for square-footage or use mismatches, the recorded deed for easements and restrictions, FEMA flood maps, sewer-versus-septic status with the town, and — for a condo — the budget, reserve position, and recent meeting minutes. A dated, written summary shared with the client before the offer doubles as risk management: failure-to-disclose claims are perennially the top source of litigation against agents.
Within a typical three-to-five-day window between first open house and offer deadline. Most Massachusetts towns expose permit history and assessor records online, registries of deeds are searchable, and FEMA flood maps are public. The constraint is knowing where each town keeps its records and having a repeatable checklist — not access.

Federal (non-MA-specific) primer on the home-buying process, inspections, and closing, for general background.
An open permit means a building inspector never signed off on the work — and neither your home inspector nor your title insurer will chase it down for you.
A condo purchase is really two purchases: the unit, and a fractional stake in the association that runs it. The paperwork tells you which one you're actually buying.
If a Massachusetts property isn't on public sewer, state law requires an independent septic inspection before the sale can close — and the result can swing the deal.
Nearly every Massachusetts home sale needs a fire-department smoke and carbon monoxide certificate. It's the seller's job to pass it — but a failed inspection is your closing that slips.
Since October 15, 2025 a seller can't make you give up your home inspection to win the deal. You can still choose to skip one — and the inspection you're guaranteed covers less than most buyers assume.
Public records can reveal insurance red flags, but only a carrier can bind coverage. Here is what to screen, what to ask, and what to put in front of an insurer before your contractual exits close.
