When a deal pops up on the market it doesn't take any time at all for it to disappear.

Sagging in a large double door entrance with cracking on the drywall above it.The main floor clearly arching over the pain beam that supports the house with clear separation between the hardwood.

At the same time there's pain coming for the new and uninitiated.A wise man once said, "In commercial real estate; somebody somewhere is screwing it up!"

Then I ask myself, what type of pain do I want?

You will not get any money for pain & suffering (distress) but would get relief from the dispute from JP Court.   

Hi Alan,Quickbooks Pro self hosted.I found it to be a pain to self setup correctly despite what they claim, but once it's done, it's done.Best to have a CPA set it up (in my opinion), and your CPA might use a different product for taxes, so the tax lines may not need to be set up.I don't see the benefit of paying a monthly fee for them to host it either.If you are online with it, what does your CPA say the benefit of online renting vs ownership is?

Since then I am nothing more than a pain in the butt to both companies who have both responded to me by effectively telling me that I am welcome to walk away — if that’s what I want.

Now before you say, "...but it's $500/month", I will tell you it isn't.Based on the area you described, and the problems you know you will encounter (as in costs, and late/no rent payments), that $500/month ($6k/yr) will disappear real fast...but the headaches won't.You're chasing a shiny object of distraction. 

Moving is a pain but if I can offer to upgrades to the units I feel like tenants are more likely to stay because they can justify customizing to their liking. 

Its a total pain to go this route.
