Most people forget about local churches, homeless shelters, mental health organizations, addiction treatment organizations, Dodd organizations, community action organizations, etc. you can use these groups for various reasons like if a tenant is struggling with rent, we have had church partners step in a pay rent.

Her mother is giving the other two to charity to help homeless people.

I get told I look homeless pretty often.  

We wanted to give back, so we decided to host a 50/50 raffle to benefit our local homeless shelter.

It was awesome (UT, historic buildings/homes, food, state parks), except the homeless population which got a bit aggressive and were building encampments along Congress St.... 

I am deeply concerned that more areas will see sudden explosions of homelessness.

You can terminate, you can double the rent, you can change it from pet-friendly to no pets, or you can tell them you want to move in your homeless brother-in-law.

Wanting to help a local organization that helps fight Denver homelessness, we quickly prepped the home for rental and the new family was able to move in within 1 week!

Having money to invest in real estate was a pipe dream because we were only a couple of paychecks away from being homeless ourselves.

I have not run into this problem personally but looking up local resources in the area and connecting him to homeless shelters may help.
