@Ryan Garrison nothing?

Now, if you can get the interest lower, which in turn would increase the CF, then even better, but if it's a choice between higher interest and higher CF, the choice is 100% of the time the same...higher CF.

FHA or a 3% down conventional loan would be a good choice. 

@Ryan Brown..I have lenders who lend on off-kilter properties and locations in OR, but being off-grid might really be out of bounds even for the most aggressive lenders. 

Unless you have a deal in the works, need cash fast, have other debts, or have fears about the market a conventional cash-out ReFi is the optimal choice.

You have made the choice, now it is about finding your investment method.

I work with a lot of investors and they tend to gravitate to some local guys, but the choice is yours of course.  

I agree with your choice, especially with foundation issues.You could also just take your time with renovations, little by little on your own free time.

If they need money choices are reverse mortgage (not a recommendation, just an option) or sell.
