How to find a roommate you won't grow to resent
Start with the routines that shape a home: sleep, work, cleaning, guests, spending, food, and noise. A friendly person with incompatible habits can still be a bad match.
Describe your own habits honestly. Say whether you cook often, host friends, work late, have a pet, or need quiet mornings. Ask candidates to do the same, then notice whether their answers are specific and consistent.
Meet before committing, check references when appropriate, and make the financial terms clear. The goal is not to predict every annoyance. It is to find someone who handles ordinary friction directly and respectfully.
A good roommate is not someone exactly like you. It is someone whose differences you can live with.
