I also wanted to search for apartments by sex of the owner (a female might be more likely to stay in a female owned listing I would think), etc-- but also, no way to search for that.

And considering you cannot control pride of ownership in totality since you're in a neighborhood reduced additional value IMHO (e.g. you cannot evict the neighbor with two cars on cinderblocks, three sex offenders living there, and 8 pit bulls tied up to the oak tree).

Assuming Bill Gates is an excellent lover (I know, gross thought) and he and his wife make love for 15 minutes, using this logic, every time he had sex it would have cost him $270,000.  

Their color and sex has nothing to do with whether they are good or bad, so you shouldn't bother mentioning it.You failed in your screening.

I can't stress enough that you need to know the area... check our local sex offender list, it often corresponds with low criteria, hence a bad area and more crime. 

You don't want a sex offender in one unit and try to lease the other side.Also have the owner sign an statement that there are no other agreements or contracts (verbal or written) concerning the property. 

You are having sex and your roommates are literally on the other side of the wall.

Does it mean roommate 1 is a non-binary sex person? 

For full and complete disclosure/transparency, I do work for Avail, so I'm limited in what I can say here as I don't want to be seen as self-promoting via the thread; having said that, I did want to provide information on what our screening entails - you can request that an app includes credit score, credit history, eviction history, nationwide criminal background check, and nationwide sex-offender check; this is in addition to the basics that are requested of the renter profile (ie. income - 2 most recent paystubs / proof of employment, a bit about their employment history, and reference checks from their prior landlord).

So in my neighborhood HOA I get it.There are people with young kids that don't want the potential sex offender or serial killer or the late night Bachelorette parties making noise at 2AM.
