I am thinking construction loan, but how to pay for it while the construction is going on is a different story.   

I don't see them showing up or paying any of the back rent that's due to become current if they wanted to stay.

Ask your employer if you can have your pay split up into three deposits, one to investments savings, one to your checking account for personal use on a daily basis, and one to an emergency account you can tap into so you don't have to tap into your investment savings.

I'm light on capital so paying a mentor isn't an option, but happy to split revenue (pay as I learn). 

In reality, you are going to be the one to pay for that.  

Section 8 refers to a voucher that some people use to pay for their housing.

So either you pay for the repair out of the idle cash in your account, file an insurance claim and use those funds, or rollover/transfer funds from another retirement account to cover the cost. 

Then she still only makes 2% extra for taking the risk of you not paying versus a bank.

That will increase your material costs for the job and is the contractor paying for the material in their bid or are you paying for it and paying them a labor cost.
