For this to make sense though, there are some important complexities I'm not yet equipped to navigate such as how the tax credits transfer to new owners, whether appraisers would factor this into the value to preserve mortgage integrity, whether installers have better pricing for investors, etc.  

Background, credit, past evictions, etc.... you'll find great successes and abysmal failures with section 8.

Also you may want to add some language that if the roof repair date (passed permit Final inspection) gets delayed and causes you to pay an addional fee for a rate lock extension, the seller credits you at closing. 

I know that I would like a tenant pool who is credit worthy, trustworthy, and not low income.

We will take the available credit against the unified federal gift and estate tax exclusion, and expect to pay no actual tax.

Step 7: Get a credit card in your name, use it for some of your regular monthly bills and pay it off every month. 

I said sure they just need to fill out a form so I can do background and credit checks.

Sofi may or may not be an option for some, they only lend to people with high credit scores and high incomes apparently.  

If you buy in higher quality areas (higher income, credit score), you’re less likely to need to evict.
