So why aren't you renting my apartment?
LOL!
I have four grown kids (two married) and one left at home who is in High School.
My wife and I were both virgins when we married and never lived with anyone else...much less slept with them. We believed it our duty to GoOd and our soceity to save ourselves for marriage and we have raised our kids that way.
There are those who still believe this out there...just keep searching. But...do be careful what you ask and how you ask it. Believe it or not, and as sad a state of affairs as it reflects, you could get into trouble.
Post in your ad and in your home when interviewing some one...in plain site..."We reserve the right to refuse service to anyone". Also, follow other Freeper advise and make sure you ask the same questions of everyone.
Consider posting your ad at churches and church colleges in the area if there are any. Best of luck...I believe the good Lord will bless you with a good renter.
