I operate in 7 markets and in each market we have a quality control manager or runner, a cleaner with at least 2 backups, and a handyman/woman.

While she was a very attractive woman, I politely declined and drove to the courthouse as fast as I could to file for an eviction.

Woman power!

If the original poster wants to increase equity and create safety (and keep the little woman happy) financially, then maintaining leverage (mortgages) is not necessary if title fraud is a major concern; put the paid-off properties into land trusts. 

I listed the home on Zillow so they could do a background check, and the woman is the only one who has done it (guy says he will do his shortly).

I ended up marrying a woman that had construction experience as well.

For inspiration "The Only Woman In the Room" by Ashley Wilson 

When that house used to be a long term rental, the woman downstairs would complain about the people up top making noise, but it's been a none issue since the conversion

The woman mentioned that she was convicted for aggravated robbery 24 years ago and served 20 1/2 years in prison.

The last rental I posted, I had a woman apply and found out she had stolen someone’s identity when I was working through the background.
