They were very helpful in helping me to figure out a solution.

@Tom Gimer has the best solution, if you have enough time to do it.When you say the house "goes up for foreclosure on May 1," do you mean that's the date of the foreclosure sale or auction?

You should refer to the IRS Website for more information: https://www.irs.gov/newsroom/opportunity-zones-frequently-asked-questions.  

Anyone have any good luck and can refer someone to me? 

Ask for local references.

We were leaning towards trying to find some electric solution to avoid the pitfall of having the tenant manage the oil delivery/payment.

I was referring to ROI.  

Thanks for the reference.

Depending on what state you are targeting, you might get into a lot of trouble contacting a borrower in default offering them a solution to their woes.

If your crew is currently working at a property we would want to see your work as a reference.
