I will continue to work a full time job and have access to another $100k I will keep in the stock market, so there is access to additional capital if absolutely necessary.Any inputs/advice would be greatly appreciated!! 

Money is the only motivator, remove it and you're likely to get people that stop caring.

I have access to about $20K more in savings and family.

Finally, I spent two years almost exclusively working with investors, providing nearly every type of financing.My guess would be this: there is a very definable trade-off between local knowledge and access to properties that "check all of the boxes". 

Side note: I have access to the property to clean up and make repairs.

A friend of mine noted that some do that to actually discourage renters during the renovation process, so they can finish and have access.

Make sure on your rental agreement that people understand they are renting a room with shared access and responsibility for the common areas.

That oughta get them motivated to stop their over use

Bigger Pockets is the one stop shop for real estate investing.

HELOC or Cash-Out Refinance would be the two most common ways to access that equity.
