You can’t make an accusation like that and then walk it back by calling it a disagreement over a "customer service issue."

Now, I am seeing people walking little dogs around. 

No one can helpfully answer the questions you pose without more specific information.Have you walked through the property?

We are direct lenders, meaning we lend our own money, for flips within approximately 1½ hours of our home.We walk through every property to avoid surprises and to confirm the rehab estimate.

The seller feels ignored and pressured—and walks away

Instead of a pile of books or printouts at least you'll probably walk away with some money when the deal's over.  

Seller will owner finance the portion she can.To those who have been walking down this path, how are you funding these projects?

This one has been walking all over you.

You could get into a solid multi-unit or a single-family rental with real cash flow instead of hoping your Katy rental eventually fills.Not saying you should walk just yet, but if leasing drags out longer than expected, would you consider selling and reinvesting somewhere with better returns?

Typically those purchasing cash aren't inspecting every home, they're walking it or having their go to GC walk it and already know what they see that may be a concern.
