So are there any specific pros/cons to home style vs choice renovation?

There's not a lot of online tutorial for setting up QBO in real estate industry so your best bet is to hire professional to set up the books and the process and teach you how to use it.

Maybe wholesaling gets its own license...As I vaguely recall, a real estate license course doesn't teach much about doing or structuring a deal. 

Clearly his selling style is incompatible with your buying style- move on.

This is something I've observed and has become increasingly common practice with a laundry list of educators out there teaching others how to be GP's.

If posters are not teaching someone how to lie they are "selfish liars" ?

Speaking as a lender (not investor) with some experience in small balance commercial lending, I can tell you that it is likely going to be tough to find financing most likely as a lot of commercial lenders tend to stay away from churches, although could be more favorable if the building is true retail/office rather than a structure built specifically in the style of a traditional church (i.e. hard to transition to other tenants if needed)

I just finished a medium style rehab and worked with a great GC.

There are still a few good resources for Log Cabins or Off-Grid style properties in remote areas as well.  

Sounds like there was not a fit in terms of style .. like a Wall Street type trying to hang out with a SoCal surfer type.
