Having a rental property is very different from renting a room out in your house. When you rent out a room, you will be sharing space with this person. Conversely, you do not live with your tenant when you have a rental property.
Renting out a room in your house requires even more scrutiny of potential roommates because you share a home with them. Many of the same guidelines apply to rental properties and room rentals, yet significant differences exist.
Sites like Spareroom.com, Facebook Marketplace, and Craiglist all offer the ability to search within a specific zip code. Make sure to set the search within a few miles of your zip code and look at the different advertisements.
A roommate ad should support your desire to find the perfect roommate and spell out the specific characteristics and attractive traits you want in a roommate.
The more specific you are in what you want, the better result you will have. You do not want phone calls from unqualified potential roommates. That makes this process cumbersome and time-consuming.
