Re: waste cleanup at cleaning establishments... OK, we have one here in town that was just this (long time dry cleaner's shop). A true horror story, with the pollution spreading out in the ground water and causing some massive expenses. The property owners quickly lost the building to the town (they simply elected to not pay their taxes...) but the clean-up costs are in the seven figure range right now (including demo of the building, and outbuilding, and clearing the lot, drilling of monitor and cleanup wells, soil removal and cleaning, etc.)
It is a very real issue, a very real expensive task. Problem was that for many years these establishments didn't have any controls on what they dumped, and the most cost effective was to usually dump on the ground (they didn't, at the time, realize just how bad it was, they thought it would just 'evaporate') or go away.
Seriously, you couldn't give me that building considering what it was before.
As to condition, I suppose I should say I was looking at it as a commercial property/investment and not as a hobby or home shop/garage. If used commercially, you'd probably have to do substantial remodeling to make it attractive to a prospective tenant. I also doubt that much maintenance has been done on it in the last few years if the current owner is, shall we say, short on cash!
BTW, the laws on hazardous waste sites are extremely complex especially regarding liability. At one time any owner in the chain could be held liable, however that has changed (generally) as it was realized that interim owners likely didn't know, and could not have known about conditions. An hour with an attorney would be a good investment if you were serious about buying it (actually any commercial property...)
