The environmental ones are the ones that can get out of control: mold, lead, and asbestos.  

I live in California where the Democrat policies have been in full force for 60 years, with massive government funded programs that give our tax dollars to pedophiles, ex cons, drug addicts and alocoholics under the guise of disability, free educations and priority to illegal immigrants, government unions demanding unsustainable benefits and wages, higher taxes a constant theme on our ballots, environmental regulations that require 8 different grades of gasoline throughout the state (which raises prices), hundreds of thousands of acres of farmland that cannot be farmed due to the Dems putting water for smelt over farmers, car registration fees so high that many lower and mid income people (especially the unemployed) are losing their vehicles, a community college system that is so top heavy it now takes 4 years for kids to finish a 2 year program for transfer to a university, and much much more.

Developers have to deal with Federal, State or Local authorities for a variety of things (Environmental, Dept. of Real Estate, Planning Depts., etc.)

That can create environmental hazards.

Take into consideration the environmental impact.Then make a informed and prudent decision based on all of the above. :-)

I can also say that aside from the police department, Denver has a "Department of Environmental Quality" which is MUCH more effective than the police department.

In many cases, you can’t examine the property from the inside and have to guess on its interior condition.You can get stuck with a house filled with building violations and environmental hazards. 

In Chicago, about 50% goes to the public school system, a little to libraries, some to environmental protection and parks, public safety, etc.

This is why I asked you what the location is - that matters.What was prior use of land, environmental impact, weather there, are there utilities, possible development... 

I paid an Evironmental Specialist approximately $1200 to research all the records with New Jersey Department of Environmental Protection.
