Boston's rental market pushes a lot of people toward strangers. Between high rents, a competitive market, and the September 1 crunch, splitting a place with someone you found on Reddit or Craigslist a few weeks ago is often the only way the math works. That's not a bad thing on its own. Plenty of good roommate matches start exactly this way. But it does mean the vetting step matters more here than it would if you were moving in with an old friend.
One Boston renter's account, shared on Reddit, is a good illustration of what happens when that step gets skipped: two separate roommates found online, both misrepresented themselves early on, and one situation turned into a months-long ordeal that couldn't be resolved with a conversation. The renter's own advice afterward was blunt: before you sign anything together, do your own work — don't just trust the vibe from a few messages.
Why vetting matters more than you think
Once you sign a lease with someone, you're financially tied to them. If your roommate stops paying their share or breaks a term of the lease, everyone named on it can be on the hook, not just them. That's true whether you like your roommate three months in or not. A bad match doesn't just make daily life annoying — since you're both on the lease, it leaves you financially and legally exposed for as long as it runs.
How to actually vet someone you found on Reddit or Craigslist
Meet in person first — and bring someone
Before you agree to anything, meet in person — ideally more than once, and in a public place for the first meeting. Bring a friend if it's someone you found online with no mutual connections. This isn't paranoia; it's just matching the level of caution to the level of commitment you're about to make.
Ask for references — and actually call them
Don't treat this as a box to check — pick up the phone and call. A previous roommate or landlord will usually tell you more in a two-minute conversation than a stranger's Reddit profile ever will. Asking for a prior landlord's contact information specifically is worth doing, since it's one of the few references that isn't handpicked by the person you're vetting.
Talk about money before you talk about move-in dates
Get specific early: how rent and utilities will split, whether anyone's income is inconsistent, and what happens if someone's late on their share. Money conversations feel awkward before you've even moved in together, but they're much easier now than after a missed payment.
Watch for the scam red flags specific to online roommate searches
A few patterns are worth treating as hard stops: pressure to send money before meeting in person, reluctance to meet or video call, vague answers about their current living situation, or pricing that seems too good to be true for the market. Set up a search-specific email if you're posting your own contact info publicly, and never send money to someone you haven't met.
Questions to ask before you commit
A short list worth going through out loud, not just assuming you'll cover it organically:
- What's your work/sleep schedule like, and how much do you work from home?
- How do you feel about guests, and how often do you expect to have them over?
- Who's cleaning what, and how often?
- Can you share a reference from a previous landlord or roommate?
- What's your plan if you're short on rent one month?
- Why are you moving, and how long do you realistically plan to stay?
Put it in writing
Even between people who get along well, a short written roommate agreement heads off most conflicts before they start. Cover the basics: how rent and utilities are split and paid, chores, quiet hours, guest policy, and what happens if someone wants to move out early. It's a separate, informal agreement between roommates, not a stand-in for the actual lease, that spells out expectations instead of leaving them assumed.
If it goes wrong anyway: what your options actually are
Even careful vetting doesn't guarantee a good outcome. Sometimes the person you signed with turns out to be someone else entirely once you're living together. If that happens, your options depend heavily on the specifics of your situation: whether you're both named on the lease, what your roommate has actually done (a genuine lease violation is different from just being a bad fit), and how your landlord is willing to get involved.
This is genuinely one of the more complicated corners of Massachusetts tenancy law, and it isn't something this article can walk you through with full confidence: the specifics turn on details a general guide can't account for, and getting it wrong (acting without your landlord, for instance) can create legal exposure of its own. If you're dealing with a roommate situation that's gone seriously wrong, your best move is talking to Mass Legal Help or a tenant-rights attorney before taking action, not after.
What's clear regardless: neither you nor your roommate can lock the other out or remove their belongings without going through the proper legal process. Self-help removal (changing locks, putting someone's things outside) creates legal risk for you, even if you feel completely justified.
FAQ
Can I just kick out a bad roommate myself?
No — removing someone from a shared living space without going through the proper legal process (even if they're behaving badly) can expose you to legal risk. Talk to a tenant-rights resource about your specific situation before taking any action.
Should I do a formal background check on a potential roommate?
It's a reasonable step, especially for someone you found entirely online with no shared connections. At minimum, verify their identity, call at least one reference, and trust a consistent pattern of red flags over a single good impression.
What if my roommate and I aren't both on the lease?
This changes your legal relationship significantly and is exactly the kind of situation-specific question worth a quick consult with Mass Legal Help or a tenant-rights attorney rather than guessing.
Is a trial period actually a good idea?
Many renters find a short trial period (a month or two, if your situation allows it) useful for confirming compatibility before fully committing, though it's not always practical with a standard 12-month lease structure.
Where do most bad-roommate situations start?
Often with skipped or rushed vetting: moving quickly because a room needs filling fast, not asking for references, or not meeting in person before agreeing to move in together.
Is finding a roommate on Reddit riskier than using a dedicated roommate-matching app?
Not necessarily riskier, but it typically comes with less built-in verification than a matching platform designed around profiles and screening. That's exactly why the vetting steps above matter more when Reddit or Craigslist is your search method.
