Questions to Ask a Potential Roommate — and How to Read the Answers

The list of questions is the easy half, and it is the half every article gives you. The hard half is the conversation: how to ask so you get a real answer, and how to tell when you have not.

Most roommate arrangements that fail do not fail because nobody asked. They fail because somebody asked, got a pleasant non-answer, and did not push.

Ask about behaviour, not preferences

The single biggest improvement you can make to this conversation is grammatical.

“Are you tidy?” invites a self-description, and almost everyone describes themselves as reasonably tidy. It is not a lie — it is a genuinely held belief that happens to be unfalsifiable.

“When did you last do the washing up?” invites a fact.

Apply the same conversion across the list:

Instead of	Ask
Are you quiet?	What time do you usually go to sleep on a weeknight?
Do you have people over much?	How many nights last month did someone stay over?
Are you tidy?	Whose job was the kitchen in your last place, and how did that go?
Are you easy to live with?	What is the last thing a housemate asked you to change?

That last one is the most informative question in the whole conversation. Everyone has been asked to change something. An answer of “nothing, really” means either they have not lived with anyone, or they did not notice being asked.

The two subjects people are politest about

Money and how long they are staying. These are the two that end arrangements badly, and they are the two people soften.

On money, “I’m good for it” is not an answer. What you are trying to establish, without running an interrogation:

• Is their income regular, or does it arrive in lumps?
• Who physically pays the landlord, and who reimburses whom?
• What happens in a month when somebody is short — is that a conversation or a crisis?

On duration, “at least a year, probably” is doing a lot of work in that “probably”. Ask what would change it. A job that might relocate, a course that ends in June, a relationship in another city — none of those are red flags, but all of them are information you want before you are jointly liable with this person.

Listen for the shape of the answer

Three patterns are worth noticing in the moment:

The reframe. You ask about cleaning; they answer about how they are generally a laid-back person. The subject was changed and the change was smooth. Ask again, more specifically.

The pre-emptive reassurance. “Don’t worry, I’m never home.” Volunteered without being asked, usually about the thing they already know is a problem.

The deflected specific. You ask for a number and get an adjective. “How many nights?” answered with “not often”. Ask once more. If you get another adjective, you have your answer.

None of these mean the person is difficult. They mean you have not reached the real answer yet, and it is much cheaper to keep asking now than to discover it in month three.

Ask what happens when it goes wrong

Almost nobody asks this, and it predicts the most.

“If one of us needed to move out early, how do you think we should handle it?”

You are not asking for a plan. You are watching whether they have ever considered that this could happen to them. Someone who says “we’d figure it out” has not thought about it. Someone who says “we’d need to agree how long the person leaving keeps paying while we find a replacement” has — and that is a materially safer person to sign with.

The same applies to the smaller version: what should happen if one of us is annoying the other? An answer that involves talking about it is a good sign. “I’m pretty relaxed, I wouldn’t say anything” is the origin story of a bad February.

Get the boring things in writing between yourselves

Not a legal document. A shared note, before move-in:

• Who pays which bill, and on what date
• How rent is split if the rooms are unequal, and why
• What notice you each give if you need to leave
• What counts as a heads-up before an overnight guest

Ten minutes, written down while everyone is still being generous. Its entire value is that it exists before anyone is annoyed.

The question to ask yourself

After the conversation, one question:

Would I be comfortable telling this person something small that was bothering me?

If the honest answer is no, the rest does not matter. Compatibility is mostly the ability to raise small things before they become large ones, and you can usually feel its absence in a first conversation even when every individual answer was fine.

And the structural point

Everything above manages the risk. It does not remove it, because on a joint lease you remain liable for someone else’s rent no matter how well the conversation went.

If the reason you are looking for a roommate is affordability rather than company, that risk is optional — an individual lease gets you shared kitchens and common spaces without shared liability. Finding roommates in Seattle works through both routes and the arithmetic that decides between them.
