I'm half way through to paying it off and it's right by Johns Hopkins Medical Center.

The other items he has absolutely no right to charge me for.We've been going back and forth with correspondence and he's recently offered to settle by offering me about half of my deposit back.

On top of that, the eviction moratorium spooked me a bit so I left all of my capital in the market during the last year and a half. 

Just be careful, you don't want to find out half way through the job that he didn't know what he walk taking about.Watch out for lead pipes, leaking main lines, plumbing that goes from galvanized, to cooper, to pex, knob and tube wiring...etc...These things will turn your investment upside down. 

(Afterwards he went hiking close by me in the mountains) He was thorough and knowledgeable and explained to me that while half of my system was used up if I fixed what was going on with it using a regular septic company it should last another 20-25 years because it would begin functioning properly and the full side would recover partially and be somewhat usable to work in tandem with the other “good” side again.

Another was one month behind and received half a month of rent.

Or at least half of it.

Basically your rent per unit is half my minimum expected return per unit.  

There are a half dozen great lenders on this forum, and I would definitely find one of them to work with.

I'm looking at a duplex that has been on the market for about half a year.
