Rentrange uses data from large property management companies just like mine.

The best approach is to set clear, written criteria, and then price the property at a rate that gets you enough applicants that you can find a few who meet your criteria reasonably quickly.

The brokerage I use has a list of contractors, inspectors, trash companies, etc.

The most reliable method to locate liens and their positions is to conduct a title search through a title company.

One of them dinged our credit and sent a late notice before I even had time to set up ACH payments with them.

Do I need to hire a property management company to obtain the rental license? 

In my case, I have residential rentals in one LLC, commercial properties in another, self-storage in a third, and my real estate company operates in a fourth.

We have a local roadside assistance company here that charges only $15 a month for hassle free roadside help here at the apartments and around our valley for our student tenants  that may be new to car troubles and away from home!

So, if you put in 20K, you could set the bid up to the amount of the 100K total debt(80K existing + 20K additional) to ensure that the property reverts to you as the lender.

This company might be a good option one day, but not now.
