What do experienced real estate investors say to a prospective tenant who wants to rent a vacant unit, but you don't want them? For example: 5 people, all 19 years old, want to rent my nice home. The non verbal cues clearly indicate "partiers". I can envision a trashed home in the short term future. The next group to view the home was a family, and again I felt very bad vibes. I firmly believe that it is better to leave a place vacant for an extra month or so , than to rent to tenants that I believe will not be good. In the past, in a stronger economy, I just stalled those people for a few days, and rented the home to a nice family. I then told the less desirable prospective tenants "Sorry we have gone with someone else". Now I get about 1 viewing per week, and that approach does not work. What do other investors say to potential tenants in such a situation? How do I turn them down and not get myself in trouble? (maybe for age discrimination, racism, or whatever other card they might wrongly think applies)
