I hear what both of you are saying @Travis Sperr and Account Closed's point - if you are buying something with a very healthy cash flow, and can withstand a 10% drop in rent or increased vacancy and still cash flow, then you don't need to worry about that property's value.

I will however, have a healthy equity position in the house.I want to continue doing deals, and right now the goal is to do flips, so that I can bank roll profits until I get enough to become a cash leverage player, rather than relying solely on financing through banks and HMLs.So to simplify, If I Buy and Hold this house, will I likely see my credit score decrease? 

As for believing the pro forma, I think @Scott Meitus has a healthy amount of skepticism, but they aren't all BS.

While in the middle of this my wife and I welcomed a healthy baby girl, our first.

My father is the pro but he is in Russia and cannot fly to help me because of his health. I

In fact, of the cash flowing markets, for out of state investors, I consider JAX one of the very best opportunities for a healthy combination of cash flow and appreciation - at still very reasonable price points.

The job and population strength of the market especially in Dallas has and continues to be impressive creating a healthy demand for apartments and rental price increases.We currently have an attractive deal in the DFW area more than happy to share w/you.  

But the collateral people damage along the way can be very stressful and not entirely healthy.

I have become a lot more healthy and dropped 27lbs. as of today.
