A renter on r/bostonhousing recently found a $1,200 one-bedroom near Longwood and wrote that "the suspiciously low price got me worried." Good instinct. Massachusetts is unusually specific about this exact moment: state law limits what a landlord can collect before your tenancy starts to four things, requires your security deposit to sit in a separate bank account you're entitled to know about, and penalizes a landlord who gets it wrong.
Most renters never learn any of that until something goes sideways. This guide covers what you can lawfully be asked for, how to hand the money over, and which requests should stop you cold.
What a Massachusetts landlord can legally ask for at signing
The four permitted charges
Massachusetts General Laws Chapter 186, Section 15B sets out what a landlord may require at or before the start of a tenancy. It is a closed list of four items:
- Rent for the first full month of occupancy.
- Rent for the last full month, calculated at the same rate as the first.
- A security deposit no greater than one month's rent.
- The actual purchase and installation cost of a key and lock.
The statute states plainly that no lessor may demand an amount exceeding those categories at or before the tenancy begins.
What isn't on the list
An "administrative fee." An "application fee." A "move-in fee." A separate pet deposit. A "holding fee" to take the unit off the market. None of these appear in the statute's list of what may be demanded before a tenancy starts. If you're being asked for one, that's a conversation to have before you pay, not after.
The distinction that matters most in practice is in the last column below.
| What you're paying | Permitted amount | Must it sit in a separate account? |
|---|---|---|
| First month's rent | One month | No |
| Last month's rent | One month, at the same rate as the first | No — but it accrues interest |
| Security deposit | Up to one month's rent | Yes |
| Key and lock | The actual purchase and installation cost | No |
| Admin, application, move-in or pet fees | Not among the permitted charges | n/a |
Where your security deposit legally has to sit
The separate account, and what you can ask to see
Your security deposit is not supposed to be sitting in your landlord's regular account. Section 15B requires it to be held in a separate, interest-bearing account in a bank located within the commonwealth. The statute goes further: the money "shall not be commingled with the assets of the lessor, and shall not be subject to the claims of any creditor of the lessor."
That last clause is doing real work. If your landlord runs into financial trouble, a properly held deposit isn't available to their creditors. An improperly held one may effectively be gone.
You are entitled to know where it is, which is what the receipt requirement below is for.
Last month's rent is treated differently
Last month's rent does not have to sit in the separate account Massachusetts requires for your security deposit. Only the deposit does. This is where the popular understanding breaks down, in both directions.
You will see renters online say that in Massachusetts your money has to be held in a separate account with the interest going to you. You will also see that "corrected" to say the rule applies to last month's rent and the security deposit alike. Neither is right.
The separate, interest-bearing, in-commonwealth, creditor-protected account requirement attaches to the security deposit. Last month's rent is advance rent, handled under a different part of the same statute: it accrues interest at the same five percent ceiling, but it is not subject to the same separate-account mechanism.
So if you paid first, last and a deposit, only one of those three is legally required to be sitting in a segregated account. Knowing which one is the difference between asking your landlord a question they must answer and asking one they don't owe you.
The 30-day receipt, and the interest you're owed
A receipt must be given to you within thirty days after the deposit is received, and it has to identify the bank's name and location, the amount, and the account number. That receipt is your proof of where the money went.
Interest accrues at five percent per year, or the lesser rate actually received from the bank, and is payable annually or on termination of the tenancy within thirty days. It can be paid to you or credited against rent.
Under M.G.L. c.186 §15B, a landlord who fails to hold your security deposit in a separate, interest-bearing account in a Massachusetts bank is liable for damages equal to three times the amount of the deposit, plus interest, costs and reasonable attorney's fees.
The statute also provides that a landlord forfeits the right to retain any portion of the deposit for failures including not depositing the funds properly, not providing an itemized list of damages within thirty days, using conflicting lease provisions, not transferring the deposit to a new owner, or not returning it within thirty days after the tenancy ends.
This is the strongest tenant-side remedy in Massachusetts rental law. It is worth knowing before you pay, not after.
How to actually pay it
Confirm who you're paying before anything moves
Before the amount matters, the counterparty does. The City of Boston's consumer affairs office is direct about this: make sure the landlord is who they say they are, and search the apartment address in the city's database to see who the actual property owner is. If you're dealing with an agent or broker, confirm they're licensed by the state. The city also suggests checking that the rental unit is registered with the Department of Inspectional Services.
Those three checks take about ten minutes and they are the single highest-value thing in this article. A scammer can copy a listing, but they cannot change who owns the building.
Which payment instruments leave you a way back
Not all money moves the same way.
- Bank or certified check, made out to the named landlord or management company. Traceable, and the name on the payee line has to match the owner you just verified. This is the default.
- A personal check. Slower to clear, which is not a bad thing here, and it leaves a record.
- Wire transfer. The City of Boston's guidance is unambiguous: never use a wire transfer to pay for an apartment, because you can't get your money back after a wire transfer. The Massachusetts Attorney General's office gives the same warning about wires and cashier's checks sent to someone you've only met online.
- Zelle, Venmo, Cash App. Built for sending money to people you already trust, and effectively irreversible. Treat a request for one of these the same way you'd treat a wire.
Get a receipt, every time
Every payment, every time, in writing, naming what it was for. You are separately owed the 30-day deposit receipt described above, but that doesn't replace an ordinary receipt at the moment you hand money over.
Also expect a written statement of condition. The statute requires it upon receipt of the deposit or within ten days after the tenancy starts, whichever is later, listing existing damage including any state sanitary or building code violations. You have fifteen days after receiving it, or after moving in, whichever is later, to return it with your own corrections. That document is what you'll be arguing from when you move out.
Requests that mean stop
None of these prove a scam on their own. All of them mean slow down and verify before money moves.
| The request | Why it's a signal | What to do instead |
|---|---|---|
| Wire the money, or send by Zelle or Cash App | Irreversible. Boston's consumer affairs office says never to wire for an apartment | Bank or certified check to the verified owner |
| Pay before you've seen inside | The most common setup in rental fraud | Insist on an in-person viewing or a verified video tour |
| "I'm out of state, I'll mail the keys" | Removes both the viewing and the counterparty check | Verify ownership in the city database before anything else |
| Send a photo of the check | No legitimate purpose at the payment stage | Decline, and ask what it's for in writing |
| Pay the security deposit in installments | Boston's consumer affairs office lists this as a red flag | Pause and verify the counterparty |
| An "admin", "application" or "move-in" fee | Not among the four permitted pre-tenancy charges | Ask which statutory category it falls under |
| "Split the broker fee with me" | Since August 2025, who pays the broker depends on who hired them | See our guide to the Massachusetts broker fee law before paying |
| Unusually low rent, or a landlord who says they aren't in it for the money | A price well under market is the oldest hook there is | Compare against current asking rents nearby. Fenway's median 1-bedroom was about $2,800 in August 2026. |
Not every Boston rental platform checks who is actually behind a listing. Every listing on Spot Easy is verified by a human before it goes up, and there are no fake admin fees on partner units, so the person you're paying is the person who actually has the apartment.
If you've already sent the money
Move quickly, and in this order.
- Contact your bank immediately. If it was a check that hasn't cleared, a stop payment may still be possible. If it was a wire, call anyway and ask about a recall. The odds are poor, but they fall further with every hour.
- Write down everything while it's fresh. The listing URL and screenshots, every message, the name and phone number used, the account you sent to, and the exact times. This is what a complaint or a police report will be built from.
- Report it. The City of Boston points people to their local police department, the Federal Trade Commission, and the FBI's Internet Crime Complaint Center. The Massachusetts Attorney General's office also takes complaints and connects people to the FBI.
If the money went to a real landlord rather than a stranger, this is a different problem with better odds. A deposit that was collected but not properly held triggers the treble-damages provision under M.G.L. c.186 §15B, and that is worth a conversation with a tenant attorney.
Who to contact
Whether a specific charge or request is lawful depends on your lease, your building, and who you're actually dealing with, none of which this article can see. If something doesn't reconcile:
- A tenant attorney or a legal aid organization, for anything involving a deposit that's already been paid and mishandled. The treble-damages provision is meaningful enough that advice is usually worth the call.
- The Massachusetts Attorney General's office, for suspected fraud and for complaints against a business.
- The Board of Registration of Real Estate Brokers and Salespersons, if a licensed agent or broker is the problem.
- The City of Boston's Office of Housing Stability, for help understanding your options as a tenant.

Frequently asked questions
What's the maximum security deposit in Massachusetts? One month's rent. A landlord cannot lawfully require more than that at or before the start of the tenancy.
Can a landlord charge me an application fee? The statute's list of what may be demanded before a tenancy is limited to first month, last month, a security deposit capped at one month, and the actual cost of a key and lock. A separate application fee is not on that list.
Does my last month's rent have to be in a separate account? No. That requirement attaches to the security deposit. Last month's rent is advance rent under a different part of the statute, and it accrues interest but isn't subject to the same separate-account rule. This is the single most commonly confused point on this topic.
How do I find out where my deposit is held? You're owed a receipt within thirty days of paying it, naming the bank, its location, the amount and the account number. If you never got one, ask for it in writing.
How much interest am I owed? Five percent per year, or the lesser rate actually paid by the bank holding it, payable annually or within thirty days of the tenancy ending. It can be paid out or credited against rent.
When do I get the deposit back? Within thirty days after the tenancy ends. If the landlord deducts for damage, they owe you an itemized list, sworn under pains and penalties of perjury, with written evidence such as estimates, bills, invoices or receipts.
What if the building is sold while I'm renting? It transfers to the new owner along with any accrued interest, and they must notify you within forty-five days. If that notice never arrives, our guide to deposits after a building sale covers what to check.
Is it ever normal to wire a deposit? Treat it as a stop signal. Boston's consumer affairs office says never to wire money for an apartment, because you cannot get it back.
