seems like they're planning to micromanage everything, which could be a real problem.

Lesson learned pay others to do the time consuming labor.

Are you going to pay a company or do it yourself?

Example, last month a renter did not pay for one of my rentals. 

There's even a business plan section available.  

Thus, this borrower is offering 90% equity ownership, with the PMP receiving 90% of the cash flow to pay down the loan.

Tenant income helping pay down my mortgage?

We'd probably have to believe it would pay us high-teens IRR, and would have to feel really confident in the sponsor's experience, construction crew, and local expertise.

(Another option to the above scenario is to instead have the LLC lend my father money to complete the rehab so all the repairs are made in his name...but then the LLC would get no tax deductions on the rehab, plus my father would wind up paying interest on the loan and the LLC would incur taxable income on the interest of the loan as well.)I've said a lot here, but It would be greatly appreciated if anyone can give me advice on the best strategy to pursue...Thanks!

I'd expect to pay $1000 - $1500 to get them installed.
