I feel that is the next step in my evolution as a real estate investor. 

The first step towards getting your first deal is researching and networking, which you are obviously already doing by joining BP.

My wife has a strong history of making nice returns on her homes, has a good eye for figuring out rehab steps that are cost-effective, and is good at staging.  

I heard that one could have four loans before it becomes really challenging to obtain financing.

Accept that, then do what you must to get what you want.You seem to still be at step 1 my friend.  

It builds on itself step by step.

I don't see any incentive for a realtor to run multiple CMA's for us on a weekly basis, if we are not using them to buy the properties because we are working directly with the homeowners and our cash buyers.I'm sure I'm missing a step or perhaps I misunderstood some aspect of running the numbers.I was under the impression (from our training) that Realtors would have no problem running comparable if we just ask them...but I just don't see why they would spend their time running comparables if they aren't getting compensated.So I'm hoping some investor friendly realtors (preferably in Topeka or Kansas City) can help clarify and answer this question for me.  

(Also, I'm curious to see how your system would work against a company with hundreds of transactions every month)For someone who has a less broad knowledge base, or more limited knowledge of Excel, your system is going to be hard to implement and challenging to maintain. 

Welcome to BP, and congrats on taking that first step!

I know every different investment has challenges but it's nice to see what other people do, successes and failures.
