The problem is there is an old oil tanker buried in the back yard that needs to be removed causing a possible environmental promblem.

I am a licensed agent in MA, a property owner in MA and have been through the process of getting a deleaded certificate.http://www.mass.gov/eohhs/gov/departments/dph/prog...http://www.mass.gov/eohhs/docs/dph/environmental/lead/all-about-deleading-2015.pdf

Not only does it possibly have environmental issues, the space itself limits who would lease it.  

As long as you have prepped the sellers if there are topography, access, utility, or any ECA (Environmentally Critical Area) issues that might have bearing on what your buyer can pay for the land. 

So the replacement cost includes the demolition and associated environmental clean up and the rebuild.

To that end I would like to businesses: fix and flip for modest income families, and build from scratch environmentally responsible homes (thinking earthship and the like).

@Niki Sharan Thanks Niki - this is not my first deal I dont want to give you that perspective - I have done alot of deals that were super hairy from mold to foundation and environmental problems I should write a post on some of the deals that went sideways so you can see the good and the bad and the ugly ;)

The best you would be able to get is a Letter of Environmental Protection, which tells everyone you did illegal work then hired a licensed deleader in to fix it.

I think I have a strong offer:- I went 4K over asking (it made sense based on comps)- cash offer- 3 weeks closing - inspection limited to environmental and structural issues It’s been a week and my offer is still under review.

It will than never be able to get a Certificate of Compliance, the best to hope for would be a Letter of Environmental Protection, which essentially tells everyone that the owner did illegal work on the property, got caught, then had to have a licensed deleader come in and fix the issues correctly.
