I am coming from a classic Dave Ramsey mentality of paying off your house in full before moving on to other real estate investments. 

The answer is private money and I've exhausted my options there.

I disagree with the new Sherrif in town mentality on the late paying tenant.

If you have a dryer get the exhaust vent cleaned out.

But there were times I was so tired physically and mentally I HAD to have my friends in certain trades do some work, and they gave me huge breaks on prices.

Our summers are long and exhausting, but our winters are perfect and last for 6 months.

Basically I have already exhausted every avenue available and I skip-trace for a living.

Looks like you’ve exhausted about as much as you can.

Research, raise your RE IQ, hang around and listen to people smarter and more successful than you, quality is better than quantity, know your limitations financially and mentally and at first take it very slow and dip your toe in the water.

Living in a multifamily property and renting out part people you don't know, I can see how it would be hard to separate "property manager" from owner mentality.
