It could just be bad luck or improper tenant screening.  

Ensure you have reserves for vacancies or repairs, properly screen tenants, switch to landlord insurance, and keep detailed records for tax time.

Worried about the city cracking down.  

Any tips on what to screen for specifically?

Go to BUILD YOUR TEAM at the top of the screen and look for local investors or meetups in your area.

Cities and communities are also cracking down on people using homes for this.

They won't be able to fix that problem as there is probably a small leak in a pipe or a crack in the foundation or a bit of water coming in from somewhere or moisture building up in the home.I also agree with Nathan about taking the first contractor to small claims court.

It’s an interesting approach, but ensuring a strong screening process and a legally solid agreement is key.
