Let Homies keep score for you
Red flags in the messages and at the viewing
The first ones show up before you ever meet. Someone who's evasive about basics, won't say their move-in date, dodges how long they want the lease, or won't get on a quick call, is showing you how they'll handle the harder conversations later. Pressure is another: a stranger pushing you to commit or transfer a deposit today, before you've seen the place or signed anything, is a flag regardless of how good the room sounds.
At the viewing, watch the apartment, not just the person. The state of the existing kitchen and bathroom tells you how people really live there, no matter what they say. And notice how current roommates talk to each other, or whether they're suspiciously absent. A room where nobody else will be around to meet you is worth a second thought.
- Evasive about move-in date, lease length, or budget.
- Pressures you to commit or pay a deposit before you've seen the place or signed.
- Won't get on a short call or meet in person before money changes hands.
- Current roommates seem tense with each other — or conveniently never around.
- The shared kitchen and bathroom are a mess at a viewing they knew about.
Money red flags
Money is where roommate problems actually live, so it's where the loudest flags are. The big one: someone who won't talk numbers. If a potential roommate is vague about what they can afford, dodges how bills will be split, or waves off the deposit, that fog won't clear after you move in, it gets worse. The exact things to ask are in questions to ask a potential roommate.
Watch for the phrases that signal trouble: "I'll pay you back" as a lifestyle, wanting to skip a written split because "we'll just sort it out," or a history of late rent they mention a little too casually. A roommate who treats your shared rent as flexible is the single most expensive mistake you can make, because their missed share becomes your problem with the landlord. If it ever gets there, here's what to do when a roommate isn't paying rent.
Communication and boundary red flags
Some flags are about temperament, not money. Someone who can't have a calm conversation about small things during the friendly getting-to-know-you phase will not magically improve once there's a real conflict over noise or guests. Listen for how they talk about past roommates: if every previous flatmate was "crazy" or "a nightmare," the common factor may be sitting across from you.
Boundary flags matter too: a partner who's clearly going to live there without being on the lease or splitting bills, vague answers about guests and overnight stays, or a dismissiveness toward your basic needs (you work early; they think quiet hours are uptight). None of these require drama to surface, they come out in ten honest minutes if you actually ask.
Dealbreaker, or just a conversation?
Not every flag means walk away. Messiness, mismatched schedules, and different social styles are usually solvable if both people name them early and agree on house rules, that's what house rules for roommates and a one-page roommate agreement are for. The dealbreakers are the ones about trust and money: dishonesty, pressure, refusing to put the split in writing, or a pattern of not paying. Those don't get fixed by a chore chart.
The cleanest filter is this: solvable flags are about habits, real dealbreakers are about whether you can rely on the person. Once you've decided someone's worth living with, the way you keep small frictions from becoming flags is to make the shared money and chores transparent from day one. That's what Homies does, one shared balance for every expense and a visible chore rotation, so nothing festers in silence. It's a whole-home app for iOS and Android, in closed beta, free while we build it, one signup for the home.
Frequently asked questions
What's the single biggest roommate red flag?
Someone who won't talk straight about money. If a potential roommate is vague about what they can afford, dodges how bills get split, or brushes off the deposit before you've signed, that's the flag most likely to become your problem — because their missed share becomes your liability with the landlord.
Should I ask a potential roommate for references or proof of income?
For a stranger you found online, it's reasonable. A quick reference from a previous roommate or landlord, or a casual confirmation that their share fits their budget, isn't rude — it's the same diligence a landlord does. Someone trustworthy won't be offended; someone who reacts badly to a normal question is showing you something.
What if I already moved in with a roommate who's turning out to be a red flag?
Separate the fixable from the structural. Habits like mess or noise can often be reset with explicit house rules and a calm conversation — see how to deal with messy roommates and house rules for roommates. Trust and money problems are different: document what's owed, keep communication in writing, and know your lease terms before it escalates.
Are messy roommates a red flag or just annoying?
Usually just annoying, and usually solvable. Mismatched cleanliness is one of the most common roommate frictions and responds well to a shared standard and a chore rotation agreed upfront. It only becomes a real flag when someone refuses to acknowledge it or to hold up any agreement at all.
Is there an app that helps keep roommates honest about money and chores?
Yes. Homies makes the shared money and chores visible to everyone: one running balance for every expense and a chore rotation the whole house can see, so small frictions surface early instead of festering.
