DSCR loan in Massachusetts: the tax break a rental loses

The seller's tax bill may not be your tax bill. Many investors run a Massachusetts deal straight from the listing. They take the seller's property tax, add an insurance quote and divide the rent by the total.

In Boston, and in any town that offers the residential exemption, that bill may include a discount the seller got for living there. You will not get it. This guide works through that number first, then the other state rules that land on a rental: lead paint, security deposits, evictions and short-term rentals.

What is a DSCR loan in Massachusetts, and how does it work?

A DSCR loan is a loan on a rental property that qualifies on the property's rent instead of your personal income. DSCR stands for debt service coverage ratio. In plain terms, it compares what the property earns with what it costs to carry each month.

No pay stub or tax return drives the approval. The lender looks at the rent and at the monthly cost. The gap between those two numbers is the qualification. For the rest of the product, from application to closing, see how a DSCR loan moves from first call to closing.

Because you will not live in the property, a loan to buy, improve or maintain it counts as business credit rather than a consumer mortgage. Regulation Z, the federal truth-in-lending rule, exempts an extension of credit primarily for a business, commercial or agricultural purpose at 12 CFR 1026.3(a)(1). Credit secured by a rental but taken out for a personal purpose is judged on its own facts.

The official commentary to that rule goes further. Comment 3(a)-4 treats credit to buy rental property the owner does not occupy as business credit. It also sets a simple test. If the owner expects to live there for more than 14 days in the coming year, that rule does not apply.

What Massachusetts actually changes

The formula is the same in every state. The inputs are not. Massachusetts lets cities and towns give owners who live in their homes a residential exemption on property tax. It also has a strict lead paint law, a strict deposit law and its own tax on short stays.

Each of those lands somewhere in a DSCR file. Some move the ratio directly. Others move the cash you need before the first tenant moves in. Mississippi reaches a similar result by another road, because there the tax class itself changes when a home becomes a rental. In Massachusetts the class stays the same, and the exemption is what goes.

How is the ratio calculated on a Massachusetts rental?

Divide the monthly rent by the full monthly housing cost. Lenders call that cost PITIA, which is short for principal, interest, taxes, insurance and association dues. A result of 1.00 means the rent covers the cost exactly.

Above 1.00, the property pays its own way with room to spare. Below 1.00, it does not. If you want to try your own figures, start by running your own numbers through the calculator. The worked example below shows each step by hand.

A Boston two-family, worked from the city's own tax rate

That clears a 1.00 floor, but only just. Notice where the tax line came from. It is the full rate on the full value, with nothing taken off.

The seller's bill on the same house may look quite different. The next section shows why, and how far the ratio moves.

What happens to the residential exemption when a home becomes a rental?

It goes away. The residential exemption is a local property tax break allowed by Massachusetts law. That law says it applies only to the principal residence of a taxpayer. A rental with no owner living in it does not qualify.

Each city or town chooses whether to offer it. Where it does, the exemption is one flat amount of value taken off every qualifying home. State law caps that amount at 35 percent of the average home value in that city or town.

Boston offers it. The city says the exemption saved qualified homeowners up to 4,353.74 dollars on their fiscal year 2026 tax bill. Because the amount is flat, a 900,000 dollar two-family gets the full figure.

The same house, the same rent, two tax bills

The gap is 4,353.74 dollars a year, or about 362.81 dollars a month. In ratio terms, it is the difference between roughly 1.10 and 1.03. That gap can decide whether a file clears a program's floor.

The rental stays in the residential tax class

The exemption goes away, but the residential rate stays. Massachusetts law puts property used or held for human habitation in Class One, which is the residential class. A two-family rented to long-term tenants is still housing.

That matters in a city with a split rate. Boston's fiscal year 2026 commercial rate was 26.96 dollars per 1,000 dollars of value, more than double the residential rate. A long-term rental does not pay that rate.

One timing point is worth a phone call. The exemption depends on who owns the home and lives in it, so ask the assessor which bill will be the first one without it. Then run the ratio on that bill, not on the one in the listing. Boston says each year's new rate appears on the third-quarter bill, usually issued in late December.

How much payment will the rent support?

Work backward from the rent. First, divide the rent by the ratio a program asks for. Then subtract taxes, insurance and dues. What is left is the largest principal and interest payment the property can carry at that ratio.

The one-line shortcut

Largest payment equals rent divided by the target ratio, minus taxes, insurance and dues. The table uses the Boston two-family from above, with every figure rounded to the cent.

Every row is 362.81 dollars lower on your tax bill than on the seller's. That is the monthly value of the lost exemption. A buyer who works from the seller's bill can size a loan for a payment the rent will not support.

Our example assumed a payment of 4,490 dollars. On your tax bill, that fits under the 1.00 row but not the 1.10 row. On the seller's bill, it misses the 1.10 row by only 9.92 dollars a month, which is why the ratio there reads 1.0980.

What does the Massachusetts lead law mean for a rental buyer?

It can add a cost before the first lease. The state's Lead Law requires owners to remove or cover lead paint hazards in homes built before 1978 where a child under six lives. Lead paint hazards include loose lead paint and lead paint on windows and other surfaces a child can reach.

The duty follows the owner, and a sale starts a clock. Under M.G.L. c. 111, sec. 197, when a home with dangerous levels of lead changes hands and a child under six will live there, the new owner shall have ninety days to fix it. Fixing it means deleading, which is having the hazards removed or covered, or containing them under a temporary plan.

You also cannot avoid the duty by choosing tenants. State law makes it illegal to refuse to rent, or to change the terms, because a home has lead paint or because renting it would trigger the law. The state also says an owner can be held liable if a child is poisoned by lead hazards in the home.

What to ask for before you sign

The seller must give you the state's Property Transfer Lead Paint Notification before you sign a purchase and sale agreement. The seller must also hand over any lead inspection reports and any Letter of Full Compliance or Letter of Interim Control.

A Letter of Full Compliance means a licensed inspector passed the home after deleading. A Letter of Interim Control is a temporary step, and the state says the owner then has up to two years to reach full compliance. A pre-1978 building with no letter is a cost to price before you make the offer.

Maryland draws a similar line for its own rentals, and how Maryland treats the same 1978 cutoff is worth reading if you buy in both states.

The state tax credit that offsets part of the cost

Massachusetts gives owners an income tax credit for lead work. For full compliance, the credit is the cost of the work or 3,000 dollars per unit, whichever is less. For interim control, it is half the cost or 1,000 dollars per unit, whichever is less.

The lead has to be found by a licensed inspector, and the owner files the compliance or interim control letter with the Department of Revenue. Keep every invoice from the start.

What are the security deposit rules, and what do you take over at closing?

Massachusetts limits what a landlord can collect up front. Under M.G.L. c. 186, sec. 15B, a landlord may require only these four things before a tenancy starts:

• first month's rent,
• last month's rent, at the same rate,
• a security deposit no bigger than the first month's rent, and
• the cost to buy and install a new lock and key.

On a unit renting for 2,941 dollars, the three rent-based items add up to no more than 8,823 dollars, plus the lock cost.

Where the deposit has to sit

The deposit stays the tenant's property. It must go into a separate, interest-bearing account at a bank in Massachusetts, out of reach of the landlord's creditors. Within 30 days, the tenant gets a receipt that names the bank and the account number.

The tenant earns interest at 5 percent a year, or the lower rate the bank actually paid. On a 2,941 dollar deposit, 5 percent is 147.05 dollars a year. Last month's rent paid in advance earns interest the same way.

The penalties are steep. Three mistakes are the costly ones: no proper account, no transfer at a sale, or a late return. For any of them, the tenant shall be awarded three times the amount owed, plus interest, court costs and attorney's fees. On that deposit, three times is 8,823 dollars before interest and fees.

What a buyer takes over

When you buy a rented building, the seller must transfer each deposit, with its interest, to you. Within 45 days of that transfer, you must tell each tenant in writing that you now hold the deposit.

If the seller never transfers it, the law generally makes you liable to the tenant anyway. So ask for a list of deposits and bank accounts before closing, and make sure the money moves with the deed.

Who pays a leasing agent now

Since August 1, 2025, a landlord who hires a broker to find a tenant pays that broker. The state housing office says a landlord cannot make a tenant pay the landlord's broker fee. It also says the fee cannot be added to the rent as a surcharge. If you plan to use an agent to lease units, count that fee as your cost.

Is there rent control in Massachusetts?

No. State law bans it. Chapter 40P says no city or town may enact, maintain or enforce rent control of any kind. The one narrow exception requires that compliance be voluntary for owners. Voters adopted that ban as Question 9 on the November 8, 1994 ballot.

A 2025 petition tried to change it. It would have repealed the ban and limited yearly rent increases. On June 23, 2026, the Supreme Judicial Court ruled in Cella v. Attorney General that the petition could not go on the November 2026 ballot.

The court found that the petition's exemption for religious facilities made it a measure that relates to religion. The state constitution keeps that kind of measure off the ballot. So for now, the market sets rents on a Massachusetts rental. Laws can change, though, so check for new proposals before you rely on steady rent growth.

How does an eviction work in Massachusetts?

It starts with a written notice and runs through a court process called summary process. A DSCR ratio assumes the rent arrives each month. This section covers what happens when it does not.

The notice comes first

For unpaid rent, a landlord can end a tenancy with a 14-day written notice to quit. A notice to quit is the written notice that ends a tenancy. A tenant at will, meaning a tenant with no fixed-term lease, can stop that notice by paying all rent due within 10 days. That right applies if the tenant has not had a similar notice in the past 12 months.

Ending a tenancy at will for another reason takes longer. When rent is paid monthly, the notice must equal the time between rent payments or 30 days, whichever is longer.

Then the court

If the tenant stays, the landlord files a summary process case. The state's Housing Court handles eviction cases along with other housing matters.

Two rules can add time. The first covers a case that is only about unpaid rent. If the tenant fell behind because of a financial hardship and shows a pending application for emergency rental assistance, the rule applies. The court must then pause the case, and it cannot enter judgment until that application is approved or denied.

The second rule covers cases where the tenant is not at fault. There, a judge can delay the move-out for up to six months in total. The limit is 12 months if someone 60 or older, or someone with a disability as the law defines it, lives in the home.

None of this makes Massachusetts a bad place to own a rental. It does mean a cash cushion for a slow month is worth planning, and careful tenant screening matters.

Can you use a DSCR loan on a Massachusetts short-term rental?

Sometimes, but Boston is mostly closed to it. For state tax purposes, a short-term rental is a stay of 31 days or less. The rules come from the state and from each city or town.

Boston requires an owner who lives there

Boston's ordinance allows short-term rentals in only three forms. Two of them are in the operator's own primary residence. The third, an owner-adjacent unit, is a second unit in a two-family or three-family building. The owner must live in another unit of that building and own all of its units.

Here is the catch for a DSCR buyer. Every Boston option needs an owner who lives in the building. DSCR loans are business-purpose loans for property the borrower does not live in. So a Boston DSCR file should be built on long-term rent.

The state tax on each stay

Every operator must register with the Department of Revenue and get a certificate of registration for each property. The operator then collects a room occupancy excise, which is a tax on the rent a guest pays.

The state rate is 5.7 percent. The law itself says 5 percent, and a separate surtax adds 0.7 percent. On top of that, a city or town can add its own excise of up to 6 percent, or up to 6.5 percent in Boston.

A professionally managed unit is generally one of two or more short-term units the same operator runs in the same town. Take an operator with two units in a town that adopted a 6 percent local excise and a 3 percent impact fee. The town is outside Barnstable County and the six convention center cities. On 10,000 dollars of guest rent, the taxes are 570 dollars to the state, 600 dollars local and 300 dollars in impact fees. That is 1,470 dollars, or 14.7 percent.

The tax is charged on the guest's rent, so it shapes your nightly price. The bigger question is whether the town allows the rental at all. State law lets each city or town license, limit and inspect short-term rentals. An operator who rents for 14 days or less in a calendar year owes no excise. That only works after registering and filing a yearly declaration first.

Is a DSCR loan on a home you live in a different product?

Yes, in practice. DSCR loans are business-purpose loans for property the borrower does not live in. If you plan to live in one unit of a two-family or three-family house, you are usually looking at an owner-occupied home loan instead.

The federal truth-in-lending commentary draws two lines. Under comment 3(a)-4, a rental counts as not owner-occupied only if the owner expects to live there 14 days or less in the coming year. Under comment 3(a)-5, a loan to buy a rental the owner will live in is treated as business credit when the building has more than two units. With fewer units, other facts decide it.

That second rule surprises people who buy three-family houses. It decides whether federal truth-in-lending rules apply to the loan. It does not turn a home you live in into a DSCR property, because each program sets its own rule on who may live in the property.

A simple way to decide

• You will not live there. This is the file a DSCR loan is built for.
• You will live in one unit of a two-unit to four-unit building. Compare owner-occupied loan options first.
• You will stay there a few weeks a year and rent it the rest. Under the 14-day test it is not a non-owner-occupied rental, so talk through second-home rules first.

What rents do Massachusetts metros support?

HUD publishes Fair Market Rents each year. A Fair Market Rent is HUD's estimate of the 40th percentile gross rent for a standard quality unit in an area. It is a reference point, not an appraisal of your unit.

HUD says new Fair Market Rents generally take effect on October 1, the start of the federal fiscal year. So the FY 2027 column becomes the current one within weeks. Worcester's figure dips slightly, and every other area in the table rises.

Use HUD's number as a check on the rent in a listing, not as the rent itself. Your unit's condition, size and street can put its real rent well above or below the area figure.

Putting the Massachusetts inputs together

Start with the tax bill without the exemption. Add a real landlord insurance quote. Check the year the building was built and ask for any lead letter. Count the deposits you will take over. Then run the ratio.

If the deal only works on the seller's bill, it does not work.
