You can share a wall with someone for a year, or you can share a year of small daily frictions with them. The difference usually comes down to a single conversation you have before move-in. A good roommate interview does not need to feel like an interrogation. It just needs to surface the habits and expectations that matter most once you are living in the same space.
Below are 40 questions grouped by topic, plus advice on how to read the answers and what warning signs to watch for.

Before You Start: How to Interview a Roommate
Treat the conversation as a two-way fit check, not a test one person passes. Ask open questions and let the other person talk, because vague or evasive answers tell you as much as clear ones. Meet in person or on video if you can, so you can read tone and body language. And be honest about your own habits in return, since a mismatch you hide now becomes a fight later.
Money and Finances
Money is the most common source of roommate conflict, so start here.
- What is your budget for rent and how firm is it?
- How do you prefer to split utilities and shared bills?
- Have you ever been late on rent, and what happened?
- How do you want to handle shared purchases like cleaning supplies?
- Are you comfortable putting our arrangement in writing?
- How would you handle a month where money is tight?
- Whose name will the main bills be under, and are you comfortable with that?
A person who is open about money, including past trouble, is usually easier to live with than someone who dodges the topic. When you settle on terms, put them in a roommate agreement so nothing depends on memory.
Cleanliness and Chores
- How would you describe your cleaning habits honestly?
- How often do you clean shared spaces like the kitchen and bathroom?
- How do you feel about dishes sitting in the sink?
- Would you rather split chores by task or rotate them?
- How do you feel about clutter in common areas?
- Are you comfortable with a cleaning schedule?
Cleanliness mismatches are relentless because they come up every single day. Look for a rough match in standards, not a perfect one.
Schedules and Sleep
- What are your typical work or school hours?
- Are you a morning person or a night owl?
- How much quiet do you need to sleep or focus?
- Do you work from home?
- How do you feel about noise late at night or early in the morning?
- Do you travel often or spend nights away regularly?
Opposite schedules can actually work well, since you are rarely home at the same time. The problem is when one person’s peak activity is the other person’s sleep.
Guests and Social Life
- How often do you have friends over?
- How do you feel about overnight guests?
- Do you have a partner who would spend a lot of time here?
- How do you feel about parties or gatherings at home?
- How much notice would you give before having people over?
The partner-who-basically-lives-here situation is a classic source of resentment, so ask directly and set expectations early.
Lifestyle and Habits
- Do you smoke or vape, and if so, where?
- Do you drink, and how does that show up at home?
- Do you have or want any pets?
- Do you have any allergies I should know about?
- How do you feel about sharing food versus keeping it separate?
- What temperature do you like to keep the place?
- How do you handle disagreements with people you live with?
Living Together Day to Day
- What does a good roommate mean to you?
- What has frustrated you about past roommates?
- What is one thing that would make living together easier for you?
- How do you prefer to be told when something is bothering you?
- How private a person are you at home?
- How do you feel about borrowing or sharing belongings?
Question 33 is quietly one of the most useful. What someone complains about in past roommates often reveals their own standards and sensitivities.
Logistics and Commitment
- How long are you looking to stay?
- What would make you want to move out early?
- Are you able to pass a background or credit check if the landlord requires one?
If you plan to be added to the same lease, question 38 matters a lot. See adding a roommate to a lease for how landlords typically handle that.
Warning Signs to Watch For
A few answers deserve extra attention. Be cautious with anyone who is evasive about money or past rental history, who describes every former roommate as the problem, whose habits clash directly with yours on cleanliness or noise, or who resists putting any expectations in writing. None of these is automatically disqualifying, but each is worth a follow-up question.
Once you have found someone who fits, protect the arrangement by writing it down and setting clear terms. Our guide to living with roommates covers how to keep things running smoothly after move-in, and if money issues ever come up, handling a roommate who is not paying rent walks through the options.
Frequently Asked Questions
How many questions should I actually ask? Prioritize money, cleanliness, and schedule, since those drive the most conflict. Cover the rest as the conversation flows naturally.
Should I interview a roommate in person? In person or by video is best, because tone and body language reveal things a text exchange cannot.
Is it rude to ask about money and rental history? No. Anyone serious about being a good roommate will expect these questions and answer them openly.
What if a friend wants to be my roommate? Ask the same questions anyway. Friendship does not guarantee compatible living habits, and the conversation protects the friendship.
Should I ask for references? Yes, especially for someone you did not know beforehand. A previous roommate or landlord can confirm reliability.
