Selling a Boston Multi-Family With Tenants in Place: Deposits, Notices, and How to Sell a Triple-Decker Without an Eviction (2026)

Selling a Boston multi-family with tenants in place is legal, common, and often the cleanest exit for a landlord who is done. The leases, the deposits, and the tenants pass to the buyer at closing. No one has to move out first.

This guide covers the state and City rules that set the price and the timeline. It also runs the carrying-cost math on a typical three-family and lists what changes hands at closing.

Can You Sell a Boston Multi-Family With Tenants in Place?

Yes, you can sell a Boston multi-family with tenants in place. A written lease binds the buyer for its full term, and a sale does not end a tenancy at will. The statute says so directly: a residential tenancy at will "shall not be terminated by operation of law by the conveyance" of the building (M.G.L. c. 186, § 13).

Ending a tenancy at will takes written notice. When rent is paid monthly, the notice must equal the rent period or 30 days, whichever is longer (M.G.L. c. 186, § 12). Nonpayment uses a 14-day notice to quit. A tenant with no such notice in the prior 12 months can cure by paying within 10 days.

Boston's triple-decker stock

Boston has 13,343 three-family parcels, and their median year built is 1905 (City of Boston Assessing, FY2026 property assessment data, May 2026). The assessor counts by unit, so the figure includes some side-by-side three-families. Only 36.8% carry the owner-occupied flag, which means the majority are not owner-occupied.

• Dorchester: 5,513 three-family parcels, 41% of the city total
• East Boston: 1,889
• South Boston: 1,013

Showing an occupied unit

Massachusetts lets a lease allow the landlord to enter "to show the same to a prospective tenant, purchaser, mortgagee or its agents" (M.G.L. c. 186, § 15B(1)(a)). The statute sets no hour count for notice. Many leases require 24 hours, so check each one before booking a showing.

What Happens to Security Deposits and Last Month's Rent?

The seller transfers every security deposit and last month's rent payment, with accrued interest, to the buyer at closing. From then on, the buyer owes the tenants (M.G.L. c. 186, § 15B).

The deposit rules

• Cap: Up front, a landlord may collect first and last month's rent, a deposit of one month's rent, and the cost of a lock (§ 15B(1)(b)).
• Account: The deposit sits in a separate, interest-bearing account in a Massachusetts bank, set up so it can transfer to a later owner (§ 15B(3)(a)).
• Interest: A deposit held a year or longer earns 5% a year, or the lesser amount the bank pays (§ 15B(3)(b)). Last month's rent earns the same from the first day (§ 15B(2)(a)).

The transfer at sale

Under § 15B(5), the seller "shall transfer such security deposit together with any interest which has accrued" to the buyer. Within 45 days, the buyer must tell each tenant in writing that it holds the deposit. Last month's rent follows the same rule as a credit to the buyer (§ 15B(7A)).

The seller stays liable until the money moves and the tenant is notified. A landlord who fails to transfer the deposit, or fails to return it properly, faces three times the deposit plus 5% interest, court costs, and attorney's fees (§ 15B(7)). On a three-family with $3,000 deposits, one mishandled unit is a $9,000 problem before fees.

How Long Does a Boston Eviction Take Before a Sale?

Even the shortest nonpayment eviction takes about a month to reach trial, and a no-fault case can be stayed for up to a year. The steps come from statute and court rules.

1. Notice. 14 days for nonpayment, or at least 30 days for a no-fault end to a monthly tenancy at will (c. 186, § 12).
2. Service. The summons goes out no later than the seventh day and no earlier than the thirtieth day before a Monday entry day.
3. Trial. Cases go on the list for the second Thursday after entry (Uniform Summary Process Rule 2).

That path adds up to roughly 31 days before a trial date, by our arithmetic from those rules. Then come the delays the law builds in. In a no-fault case, a judge may stay the judgment for up to 6 months, or 12 months for a tenant who is disabled or 60 or older (M.G.L. c. 239, § 9). In a nonpayment case, the court must continue the case while a pending rental assistance application is decided (M.G.L. c. 239, § 15).

Boston cases are heard in the Boston Session of the Eastern Housing Court at the Edward W. Brooke Courthouse, 24 New Chardon Street. It serves Dorchester, Roxbury, Jamaica Plain, Mattapan, and other neighborhoods (Massachusetts Trial Court, September 2026). Every continuance or stay pushes possession further out. Selling to a buyer who takes the tenancy skips that calendar entirely.

Boston Rules a Landlord Carries Into the Sale

Boston adds a rental registry and a tenant notice rule to state law, and the state lead law applies when a child under six lives in the building. Each follows the building to its next owner.

Rental registration and inspection

Every Boston rental registers every year by July 1 (Boston Inspectional Services, updated October 2025). Fees are $25 per unit the first time and $15 per unit on renewal, capped at $2,500 per building. Late owners may pay a $300 penalty each month, and never-registered owners owe fees back to 2013.

The City inspects each rental "once every five years," at $50 per unit in a one-to-three-unit building (Boston Inspectional Services, September 2026). Buildings of six or fewer units with the owner living in one are exempt from inspection. Sell an owner-occupied triple-decker to a non-occupant buyer, and that exemption ends.

The Housing Stability Notification Act

Any Boston landlord ending a tenancy must deliver the City's Notice of Tenants' Rights and Resources with the notice to quit or non-renewal. The landlord also files a copy through the City portal, and failure "may result in a fine up to $300 per day" (City of Boston, September 2026).

Lead paint and children under six

Whenever a child under six lives in a unit with dangerous levels of lead, the owner must abate or contain it (M.G.L. c. 111, § 197). After a sale, the new owner has 90 days to comply. In the FY2026 assessment file, 97.8% of Boston three-family parcels were built before 1978. Our guide to Massachusetts seller disclosure requirements covers the lead notification form due before the purchase agreement.

Broker fees on re-leasing

Since August 1, 2025, a rental broker's fee is paid only by the party who hired the broker (St. 2025, c. 9, § 43, amending M.G.L. c. 112, § 87DDD½). A landlord who lists a vacant unit with a broker now pays that fee, and it belongs in the turnover math below.

The Condo Conversion Ordinance, If Converting Is the Plan

Converting a Boston rental to condos triggers long tenant notice periods, relocation payments, and City permits under the Condominium and Cooperative Conversion Ordinance. The City describes coverage as buildings built before December 1983 with four or more rental units (Mayor's Office of Housing, September 2026).

• Notice: One year for most tenants, and five years for elderly, disabled, or low- and moderate-income tenants.
• Relocation: $10,000 per unit, or $15,000 for tenants with enhanced protection.
• Purchase right: Tenants get the first right to buy their unit.
• Permits: $1,000 per unit for the Conversion Plan and Permit, and no unit sale before the permit issues.

The four-unit threshold suggests a three-unit triple-decker falls outside the ordinance. That was not confirmed for this guide, so ask the Mayor's Office of Housing before counting on it.

The Carrying-Cost Math on a Boston Three-Family

A typical Boston three-family owned by a non-occupant costs about $1,400 a month in taxes and water before insurance, repairs, or a mortgage. The figures below are illustrative arithmetic on published rates.

• Property tax: The median three-family is assessed at $1,082,100. At the FY2026 residential rate of $12.40 per $1,000, that is $13,418 a year, or about $1,118 a month (Boston Assessing, FY2026).
• No residential exemption: The exemption is for owner-occupants only. Last fiscal year it saved qualified owners up to $4,353.74 (Boston Assessing, September 2026).
• Water and sewer, if the owner pays: The 2026 combined rate starts at $136.87 per 1,000 cubic feet and rises by tier (Boston Water and Sewer Commission, 2026 rates). At 60 cubic feet a day for the building, that runs about $280 a month.
• Insurance: Use your actual premium; older frame buildings often cost more to insure.

Vacancy and turnover

Zillow's rent index for Dorchester's 02124 ZIP was $3,039 in August 2026, against $3,338 citywide (Zillow ZORI, August 2026). One unit empty for one month costs a full month's rent. Add cleaning, painting, and a broker fee if you hired one.

Statewide, the median 2-to-4-unit sale price fell 2.5% to $728,000 in August 2026, with 3.6 months of supply (Massachusetts Association of REALTORS, August 2026). The 30-year mortgage rate averaged 6.95% in the week of September 17, 2026 (Freddie Mac PMMS, September 2026). For current Boston prices, see our Boston housing market 2026 report.

What Transfers With the Building at Closing

At closing, the seller hands over the leases, the deposits and last month's rent with interest, and the records needed to run the building. The closing attorney credits those amounts to the buyer on the settlement statement.

Estoppel letters and ledgers

An estoppel letter is a short form in which each tenant confirms the rent, deposit, last month's rent, lease term, and any side agreements. A clean package also includes a rent ledger for the last 12 months and a deposit ledger with bank names and interest paid.

An illustrative ledger for a Dorchester three-family might read:

• Unit 1: tenant at will since 2016, $2,700 rent, $2,700 last month's rent held
• Unit 2: lease to June 30, 2027, $3,000 rent, $3,000 deposit held
• Unit 3: lease to August 31, 2027, $3,100 rent, two months behind

Prorated rent

Rent for the month of closing is split by day, and the buyer is credited for the days after closing. Past-due rent, like Unit 3's, needs a written deal on who keeps the claim.

How to Sell Rental Property With Tenants in Massachusetts for Cash

To sell rental property with tenants in Massachusetts for cash, pick a buyer who takes the building as it stands, leases, deposits, and problem tenants included. That removes the eviction, the vacancy, and the showings.

Propcash is a direct cash homebuyer that can buy with tenants in place, so no eviction is needed before you sell. We make one transparent, data-backed offer and show how we got to the number. There are no fees or commissions to Propcash, you sell as-is, and you pick the closing date.

A cash sale of a Boston building can often close in as few as 14 days, and the calendar sets the pace. In Massachusetts, a closing attorney handles the closing by long-standing practice (REBA v. NREIS, 459 Mass. 512, 2011). The Boston Fire Department needs at least 10 business days' notice to book the smoke and carbon monoxide inspection (Boston Fire Prevention, September 2026).

If your leases end soon and the building shows well, listing it may net more. If a cash sale is not your best move, we will say so and can point you to a local agent; we may receive compensation from agents we refer. You can get a cash offer on your Boston multi-family and compare it with your other options. See how a direct sale works on our Boston cash sale page, the Massachusetts overview, and our guide for tired landlords.

Frequently Asked Questions

Can I sell my Boston triple-decker with tenants living in it?

Yes, you can sell a Boston triple-decker with tenants living in it. A lease binds the buyer, and M.G.L. c. 186, section 13 says a sale does not end a residential tenancy at will. The tenants stay, the buyer becomes their landlord at closing, and the deposits and last month's rent move to the buyer with interest.

How do I sell rental property with tenants in Massachusetts without evicting anyone?

Sell to a buyer who takes the building as it stands, leases and all. You hand over the leases, a rent roll, a deposit ledger, and the deposits with interest, and the closing attorney prorates the rent. No eviction is needed when the buyer wants the tenants to stay.

What happens to tenant security deposits when a Boston multi-family is sold?

Under M.G.L. c. 186, section 15B(5), the seller transfers each deposit with its accrued interest to the buyer. The buyer must notify each tenant in writing within 45 days that it holds the deposit. The seller stays liable until that transfer and notice happen, and a failure to comply can bring treble damages plus attorney's fees.

How much notice does a Massachusetts tenant at will get before the tenancy ends?

For a monthly tenant at will, written notice equal to the rent period or 30 days, whichever is longer, under M.G.L. c. 186, section 12. Nonpayment cases use a 14-day notice to quit instead. In Boston, the landlord also delivers the City's Notice of Tenants' Rights and Resources with any notice to quit.

Does the Boston condo conversion ordinance apply to a three-family?

The City describes the ordinance as covering buildings built before December 1983 with four or more rental units. That threshold suggests a standard three-unit triple-decker falls outside it, but confirm with the Mayor's Office of Housing before relying on that. Covered buildings owe tenants one year of notice, or five years for elderly, disabled, or low- and moderate-income tenants.

How fast can a Boston multi-family with tenants close?

A cash sale often closes in as few as 14 days in Boston, and the calendar is the limit. A closing attorney handles the closing by long-standing practice, and the Boston Fire Department books the smoke and carbon monoxide inspection at least 10 business days out. Tenants in place do not add time when the buyer is taking the leases.

Propcash is a direct cash homebuyer, not a law firm. Talk to a Massachusetts-licensed attorney before serving a notice to quit, transferring deposits, or signing a purchase agreement on an occupied building.
