The Offer to Purchase (OTP) Trap: Can a Seller Back Out Before the P&S in Massachusetts?

Current as of: September 16, 2026 Residential Real Estate Transactions Massachusetts
In Massachusetts, an accepted Offer to Purchase is a legally binding contract, not just a preliminary handshake. If a seller tries to back out before signing the final Purchase and Sale Agreement, the buyer can sue to force the sale of the home.

Buying or selling a home in Massachusetts involves a unique "two-step" legal process that catches many out-of-state buyers and first-time sellers completely off guard. Whether you are bidding on a condo in Boston, a colonial in Worcester, or a townhouse in Cambridge, the transaction begins with an Offer to Purchase (OTP), followed 10 to 14 days later by a much more detailed Purchase and Sale Agreement (P&S). Many people assume that the deal is not "real" until the P&S is signed. This is a dangerous misconception.

A signed OTP is generally a fully binding legal contract. If a seller gets cold feet or receives a better offer after signing the initial offer, they cannot simply walk away. The landmark Massachusetts case McCarthy v. Tobin, 429 Mass. 84 (MA Supreme Judicial Court 1999) forever cemented the rule that if an OTP includes all essential terms (price, closing date, deposit amount), it is enforceable. Engaging a local real estate attorney from our directory before you sign any paperwork is critical to avoid being trapped in a deal you want to escape.

Step-by-Step Dynamics of the Massachusetts OTP

Understanding how the Offer to Purchase locks both parties in is vital. Here is how specific situations unfold under Massachusetts contract law.

Seller Cold Feet

It is common for sellers to experience extreme seller's remorse shortly after accepting an offer. They might realize they priced the home too low, or their plans to relocate might fall through. However, once the seller signs Form RA101, Massachusetts, Greater Boston Real Estate Board, Offer to Purchase Real Estate, they are legally bound to proceed. If the seller refuses to negotiate or sign the upcoming P&S agreement, they are actively breaching the contract. The buyer's attorney will immediately intervene to demand compliance.

What Happens When a Better Offer Comes In

In a hot housing market, a seller might accept an offer for $600,000 on a Friday, only to receive a cash offer for $650,000 on Sunday. A seller cannot legally accept the higher offer if they have already signed an OTP with the first buyer. If the seller attempts to back out to take the higher cash offer, the first buyer has the legal right to block the new sale and drag the seller into court.

Buyer Waiving Contingencies

While the OTP binds the seller tightly, buyers often include "contingencies" (like a home inspection or securing a mortgage) that give them a legal escape hatch. However, in highly competitive markets, buyers sometimes waive these contingencies to make their offer more attractive. If a buyer waives their inspection and mortgage contingencies on the OTP, they have eliminated their legal right to back out. If they change their mind, they risk forfeiting their initial earnest money deposit (usually $1,000) and potentially being sued for breach of contract.

Specific Performance Lawsuits

If a seller flatly refuses to sell the house after signing an OTP, the buyer's ultimate weapon is a lawsuit for "Specific Performance." Filed in a court such as the Middlesex County Superior Court, Woburn or the Suffolk County Superior Court, Boston, this lawsuit asks the judge to force the seller to hand over the deed. To prevent the seller from selling the home to someone else during the lawsuit, the buyer's attorney will file a "Lis Pendens" (a notice of pending litigation) at the local Registry of Deeds. This completely clouds the title, making it impossible for the seller to sell the house to anyone else until the lawsuit is resolved.

How Much Do Real Estate Attorneys Cost in MA?

Hiring a real estate attorney for a standard residential closing in Massachusetts is surprisingly affordable because most charge flat fees. A buyer or seller can expect to pay a flat fee ranging from $800 to $1,500. This covers the attorney reviewing the OTP, negotiating the P&S agreement, and handling the final closing. However, if the deal falls apart and turns into a Specific Performance lawsuit, flat fees no longer apply. Civil litigation attorneys charge hourly rates between $300 and $600, and a full lawsuit can quickly cost $10,000 to $30,000.

Timelines in the OTP Process

The timeline is incredibly fast-paced. Once an OTP is accepted, the buyer usually has 5 to 7 days to complete a home inspection. The parties then have 10 to 14 days from the date of the OTP to negotiate and sign the final Purchase and Sale Agreement. Closing typically occurs 30 to 45 days after the P&S is signed.

Frequently Asked Questions (FAQ)

Can a seller reject an offer that meets their full asking price?

Yes. A listing price is merely an invitation to receive offers. A seller is never legally required to accept an offer, even if it is above the asking price, as long as they have not yet signed any paperwork.

Does the OTP need to be notarized to be binding?

No. An Offer to Purchase does not need to be notarized to be a legally binding contract in Massachusetts. A simple signature, or even a verified electronic signature (like DocuSign), is fully enforceable.

What if the OTP says 'Subject to a mutually agreeable P&S'?

Courts have ruled that this language does not make the OTP a mere preliminary draft. It is still binding. Both parties are legally required to negotiate the subsequent P&S agreement in good faith.

Can I back out as a buyer if I find a better house?

If you back out without a valid legal contingency (like a failed inspection), you are in breach of contract. You will lose your initial deposit and potentially face a lawsuit from the seller for damages.
