I believe most So Cal investors who invest in Midwest turnkey properties likely would have been better served investing locally.However, if I were in one of those low cost Midwest market, I have confidence that I could make RE work in that market.Mostly I believe smart RE investors can profit in virtually any RE market.  

My theory is the owner reworked the delinquent loan, and now that the loan is performing they're getting out while they can.

With either an engineering or craftsmanship that requires that amount of periodic rework of major building components, most houses would be constantly under renovation!

I have had 2 additional plumbers look at the work and don't want to take on the re-work.

Well done on taking initiative and control in moving from "why are these guys so much money" (as the Agent in CPA role) to becoming the Principal with your RE work. 

Looking for investors who want a working interest in these wells - by funding the rework.

No, "shmoozing" loan officers at banks can't get a big loan with a 428 FICO and Chexsystem after you, etc but it can put you over the top OR maybe get some friendly terms to re-work an existing loan if you hit a rough patch which nearly everyone does at one time or another, where the person with no relationship and personal trust built up may just get their loan yanked in the same situation.

Unless you want to work & re-work the DRAFT HUD-1 wait until 1 day prior to closing, 2 days at the most.There will be prorated items directly related tot he closing date such as: property taxes and rent (if applicable).My experience is that the HUD-1s are wrong about 50% of the time.

If you don't know the product or service that you are selling very well, it is hard to expect great success.I have only been around bigger Pockets a short while and it has been both exciting and amazing to hear how some have applied what they learn and really make RE work for them.

., good job reworking the analysis.
