@WillBarnard I am a big skeptic, but I'm the type to fight my second guessing and take a risk, so I bought into the "opportunity" because of the "no money needed pitch".

so we both protect ourselves and interests, don't want to have a multi million dollar empire and fight over money not good!.

I am in the same field, and I got into real estate and think it works fairly well with education (if your job has some flexibility like mine)...I can recall spending like a hundred grueling hours fighting over half someone's deposit in the legal aid office and stalling the eviction an extra week or two on  technicalities (a noble cause for sure), but they still, of course, were evicted eventually with no money.

They rarely fight.

Essentially, you are paying for something you hope you never have to use....but if it does happen, you have multiple parties in your corner fighting off a claim, for many years if needs be, and even if the limits of one were exhausted, you have another...and the legal fees alone could be large, so nice to have the insurers footing that bill and having an interested in settling or disposing of the suit....great question, though, could you be overinsured?

While they will fight, complain, try to talk their way out and make you hold their feet to the fire.

Just because a tenant says that they are going to fight you doesn't mean they actually will.  

I think you should look more at them as a whole profile, I know people who have been arrested and never charged because a jealous ex lover called the cops over a fight you just never know.If she has a great credit score, Landlord reference and has been gainfully employed for 3+ months and her boss gives her a good review.

It's hard for any tenant to fight that in court.

He can't fight that.
