That said, it has been something people have complained about for some time, but there are no easy solutions.

I gave what i hinted to what i thought is a logical solution, and actually the only solution that we can even play a part.

Sugar is a good open source solution.

If you can find sellers that need help and provide a solution you are not taking advantage but actually helping them out.

He basically said without taking a backhoe to the under the footing of the house in that area, it could be a "simple" 5k solution, or as expensive as 20+...so unless the seller can come down 15 or so (unlikely) I'm onto the next one.

More specifically, I think it might be possible to use technology to build a more modern property management company. 

That's human nature, and last I checked, technology haven't provided a solution for that.

I'm not saying it's the most by the book solution but it's often the easiest, especially if the vehicle has no value other than scrap and you don't expect anyone to come back for it.

Since closet was already there, it was a plumbing only solution. 

Put a few drops on the trail and wait a few days.if that doesn't work you need a more industrial strength solution.
