If you’re applying on your own, you could say:

I’m a responsible, respectful, and easygoing tenant who values a clean and comfortable home. I’m mindful of shared spaces, communicate clearly, and am considerate of neighbors and housemates. I keep a fairly quiet lifestyle, pay rent and bills on time, and take pride in maintaining a tidy living environment. I’m looking for a place where everyone can feel comfortable, respected, and at home.

Or a slightly warmer version:

I’m friendly, reliable, and easy to live with. I’m respectful of other people’s space and schedules, keep common areas clean, and believe good communication makes for a great living situation. I enjoy a peaceful, low-drama home environment and am looking to contribute positively to the household.
