When the recession hit I never dropped rents on current residents.  

I have a business license in my state of residence.

We paid off about half of it very quickly because it was at a higher interest rate and I wanted to get our DTI down to purchase a primary residence, but I am making the minimum payments on the rest of it for the reasons I stated above.

I live in North Texas where cities encourage larger expensive houses in an attempt to get high income residents.

Otherwise, I would absolutely give a written notice of the termination of their residency.

I'm looking to purchase an investment property and have around $100K liquid to use, as well as the equity in my current residence.

Acquire outdated, fixer upper property North of Dallas as my primary residence using FHA 203K loan.a. 

I currently reside in Washtenaw County for my current job.

My name as you can see is Glen Parmenter I reside in Arlington Texas with my amazing wife Aimee.

If you're living in one unit then your rent roll is really just whatever the other 3 units will provide, are you planning to stay in that one unit, or move to a private residence/next investment once the rehab is complete?
