Do what you can to get her to leave without needing to file for eviction with the court.

You likely don't want your first investment to be halfway across the country with a contractor you know nothing about in a city where you have never been.

He calls me yesterday to tell me that the court took away his POA and the house.

Guess what your expected cash flow just went down the toilet for a few years.I think out of the country investors should not be buying these low quality properties and areas.

In particular, the fact that being setup to invest remotely means the entire country (world?)

Those that charge $400 for the SD rent their units faster and tend to end up chasing tenants for damages/lost rent through the court system.Be aware that there laws related to security deposits and in some states here there are limits on the amount of security deposit a landlord can collect.

we also self manage across the country. 

After the auction the courts will issue a deed placing the purchaser at auction in title to the property. 

It will effect transactions all over the country. 

We are buy and hold investors who own all over the country.
