@Roger Garner all of the above give you great ways to find GCs, but HOW will you screen the bad from the good?

My strategy is to hold it long-term, leveraging the steady rental income while benefiting from potential appreciation.

You want an accountant who can help you strategize and who is responsive when you want to know the consequences of the financial decisions you are making throughout the year.There are over 20 real estate accountants on this site.

There are "turn key section 8" operators in Alabama that market to do all of the due diligence for you and you never even have to see the properties! 

There's not a good reason to not ask for the allowed rent, the tenants portion generally is based on a percentage of their income not a percentage of rent. 

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.

Keeping a 2.99% rate sounds great, but it may be costing you thousands of dollars if you are in the double digits with your other outstanding debts.

For further background, I’m looking to purchase a spot around 750K, but want to seller finance 100-200k of the price to reduce the need for a large down payment / keep myself liquid for renovation costs. 

For example is the 3/4" settlement in a main area of the home, is it in a basement?

One of the biggest mistakes is to focus on solely cash flow and achieving a BRRRR.
