Part 2 of 5 Steps for Finding a Good Housemate
Look for someone who is financially stable, shares some of your interest, has a similar lifestyle, and enjoys the same level of cleanliness (or chaos). This will help you avoid the most common roommate arguments.
If you have physical limitations, select a roommate with different restrictions so that you can help one another. Choose someone who compliments your strengths and weaknesses.
A poor choice may result in less interaction and more loneliness, so be sure to agree to a "trial" period, for everyone's sake.
