This was an auto body shop and paint booth for over 20 years and not used for mechanical work much at all. 

Have you ever taken on installment debt in the past (Student Loans, Auto Loans, ect.)?

Auto credit reports.

I have student loans, medical bills form a bad accident, and some dumb stuff from when I was younger.  

However, you can do another flip to deal with the auto loan.  

With any type of auto-filtering system there is always going to be a small percentage of loss.

Then, I ask if the tenant has paid on-time every time.Credit report: Another good indicatorAuto-payment:  I recommend that every investment owner tries to get their tenants on an auto-payment online system.

We auto collect rent with software. 

Up till recently, our agent of many years used Travelers for our home, auto, NOO rental, and umbrella.

I ended up here almost by accident but I wouldn't move now and do this job elsewhere in the USA for anything less than eight figures.
