I am wondering what the most efficient way is that people have found to locate the contact information for the owner of that home. 

ROI is a rate of return, not a payback period. 

I'm currently a mining engineer in an open cut coal mine and a lot of my job is evaluating the most efficient way of doing something.

(That's an important question for EVERY property you buy).At the start, you will likely have to wait 6 months for each successive refi, but once you get a few under your belt, with accordingly increased ongoing cash-flow, the seasoning periods might be able to be applied to earlier properties once further appreciation kicks in too, allowing you to speed up your deal-making regimen?

What I discovered is something I have never seen anyone speak about on Bigger Pockets (I am sure someone has discussed this I just have not seen this idea discussed at all...or anywhere in my short research period on cash flow and real estate properties.We hear everyone speak about Cash Flow, NOI, Cap Rate or Cash on Cash returns.. however I think there is another important benchmark for investors to consider when deciding their down payment percentage and financing levels because of their effects on cash flow...Capital Cost per $1 of Cash FlowOne of the most illuminating aspects of real estate investing is financing isn’t bad...Having spent all of my life not accumulating debt this has been a difficult psychological barrier to break through.

If you are going to owner-occupy, you also want to benefit from the OO preference periods offered by HUD, Homepath, and Homesteps.

So it seems the first few properties might be slower since I would use conventional bank mortgage loans and then wait a seasoning period (6-12 months ?)

So, this option would require us to pay two mortgages for a period of time (which, obviously, we prefer not to do). 

At this point or above in credit scoring, conventional financing is more efficient in terms of cost in most cases.

I'm on a short trip to DFW and would love the efficiency of a list.
