She did not leave, so i went to file for an order of possession, she left the property the night before the eviction date, since i drove by the property everyday i kind of knew she was going to stay there until the last minute, i saw when she started moving and followed them, so i know where she lives now.

Neighborhoods to stay away from? 

Do you stay under a certain all-in number?

If you don't know what a unit will rent for, you have no idea what you can pay for it and cash flow.I'll leave it at that, but stay focused, be willing to spend some time and be patient, and you should be able to have success here.

You must stay on top of it and be fully aware of the regular operations.

Nicely done @Brian Ellis - way to stay positive throughout the whole experience.

I believe it has to stay your primary residence for a year after but someone correct me if I’m wrong. 

The loan stays in the first owner's name but you are making the payments.

Usually, the Unpaid Principal Balance (UPB) stays the same and all of the arrears, additional interest, fees, etc. are added together and become the new "deferred principal balance."
