I am talking into the six figures based on problems found and vintage age of the building.They key to the whole thing is location for redevelopment for a higher value and also the repairs needed and any contamination to the ground.

Just make sure you have something in there that says that the owner will remove (not just decommission but removr) any discovered inactive underground storage tank and remediate any contaminated soil if found.

Looking to buy a parcel of land, used to be a gas station. 10 years ago they shut down, did a phase 2 and found contamination from the storage tanks.

Flushing household chemicals, gasoline, oil, pesticides, antifreeze, and paint can stress or destroy the biological treatment taking place in the system or might contaminate surface waters and groundwater.

For example, They could have found an underground storage tank (for oil heating - a big issue up this way) or discovered soil contamination and the seller offered a reduction in the purchase price because of it.

So, any intelligent person would be pretty flawed to have a legitimate concern for living in a building where someone from Ebola has died (and let's just give it like a 3-week window period after someone in this building was infected to be appropriately cautious of contamination with neighbors).

Trouble is that open systems with race track shaped pools get contaminated easily with non-productive algea, and closed systems are expensive.

That way if there is a problem in one 'pot' the mess does not contaminate the assets in the other 'pot'.If you were a doctor it might be wise to have the family home owned by your wife if she is less likely to be sued.

There was minor soil contamination.

You would have to dig it up and make sure the ground is not contaminated for a pretty big radius around the drum.
