If you hired an agent or a broker to work with you, you'd be covered - but regulations & laws vary from place to place.Screening is best done by establishing a set of guidelines to qualify applicant tenants, then sticking to those rules to avoid legal issues (and for your own sanity).

These include accidents (I recently had 2 units destroyed by fire), natural disasters (I have had two units each hit by 2 hurricanes), property management turn over (they sell or stop being as good, I have experienced both), or turn over of team (I am turning over at handyman and I suspect plumber), or just wear n tear of property (slab leak in poor location, sewer pipes rotted out (one unit this month), roof, foundation issue, etc.).  

It depends on your local laws.

We definetly would face similiar issues with facebook regarding discrimination issues. 

It sounds like you are not in compliance with those laws if you don't live nearby.

I kind of gave up on Stessa, just do not have the time to deal with ongoing computer issues and constantly not being able to communicate with a company.

But there's no body of case law indicating that to be a concern.

You have a personal issue- car engine blows up, so you tell your tenant that they need to pay double the rent for one month so that you can get your car fixed?

How do you handle disputes or issues during the project?

If issue is overhanging limb, remove the overhanging limb.
