I drove around the properties on my own, thus eliminating much unnecessary legwork on his part. 

Maybe not, maybe they appreciate, maybe you don't care, with the money you pulled out, you added enough "actual" value in other investments, but unless one of the "maybes" is "you plan to skip town and default", eventually, even if legal, this will require some dumb luck not to put you in a deep debt hole. 

The No money down would be a possibility if the ARV is high and you refinance the property. basically a BRRRR.From the numbers of the cost and income at say 5%-5.7% interest rate I don't think the property will cash flow before Tax if your debt is $670k. did you run the numbers in a calculator, working out the NOI etc?

I hope that these run themselves with the cash flow it is generating; including my debt service and expenses. 

I've been knocking out debt for a while so cash-flow is high without getting more tenants and more toilets. 

As of right now I’m saving money slowly but at the same time paying off debt from college etc....

A good bonus would be if they are one of the banks with a reasonable portfolio of distressed debt they are offloading.

You need to eliminate them before they get in rather than after.

There is no connection between property taxes and national debt.
