Can someone guide me or direct me how can I buy a REO property ?

I recently had a total loss fire in one of my rental properties.

We are nearly finished renovating a rental property in Oklahoma, and have started rehabbing our primary home in Tucson, AZ.

We were buying and selling hundreds of properties from 2009 - 2015.

Looking to buy our first investment property in the North Dallas area.  

Goal to own 10 rental properties over the next 3 years networking with like minded people. 

Here are a bunch that will help your research.https://www.biggerpockets.com/users/ZacharyCole/referenceshttps://www.biggerpockets.com/forums/92/topics/765347-rent-to-retirement-reviewhttps://www.biggerpockets.com/forums/92/topics/1116050-a-huge-win-with-cori-from-rent-to-retirementhttps://www.biggerpockets.com/forums/850/topics/895660-my-first-investment-property-an-out-of-state-dealhttps://www.biggerpockets.com/forums/88/topics/1047543-big-profits-from-new-construction-sfr-build-in-cape-coral-flhttps://www.biggerpockets.com/forums/92/topics/983659-first-investment-property-with-rent-to-retirement?

Are you living in it or is it a pure investment property? 

You want to take a second loan (HELOC) on your primary residence to use it to go get a third loan, first on a new property?

Do I have to request this maltreatment of the property to quit first before noticing to evict?
