i owned a station years ago, one of the biggest issues was if the soil is damaged from tank leakage.

They back dig it, put in gravel and drainage, pull it plumb and tie it into the back soil.

Before buying land, I would make sure to hire the right experts to assess the land topography, it’s soil quality to determine what size septic would be allowed.

.)#2 Rezoning to Approved Plot Plan where you hire engineers to get plan approved by the city/town to have structures built on the land#3 bring utilities to the lot line ready to go (water, sewer, gas, electricity) if out of city you may have to build your own waste water plant or septic system for sewer and drill well for water#4 clearing trees, grading land to have soil elevation to be relatively flat#5 bringing all utilities to each individual lot (residential subdivision, mobile home park) #6 build roads Hypothetically speaking your $100k raw land could be worth $250k after its been approved by the town to have 10-15 mobile homes built on it or worth $350k after you cleared all the trees and grading and have all utilities at the lot line.. 

It feels highly unethical that they basically yanked the rug out from underneath me and put me in a position where I have no other choice.

There are no photos of the electrical, plumbing, foundation, pipes, underneath the deck, the garage supports on Zillow.

The battery manufacturing/disposal is not just about the environment (atmosphere), it is about the chemicals leaching into the soil.

It is also a great way to go bankrupt, lose everything and be forced to work like a dog until the day you die trying to get out from underneath your mistakes.

I'd have the seller pay to remove them and have a qualified company test the soil to check for leakage.

Hopefully it didn't get in the groundwater and it's only in the soil.
