@Joshua Carter a SIGNIFICANT portion of my due diligence and inspection process requires the utilities to be on.For instance, I run all plumbing extensively to check for leaks, I ensure that appliances are functioning correctly, I check all lights and electrical outlets for functionality & ground, we check the fuse boxes for functionality & condition, we assess the performance of furnace & AC systems, and water heaters, we check the functionality & safety of the gas lines, scope the sewer main and assess water flow, test for radon & meth contamination, and basically give the entire property a thorough "test drive"  --which isn't possible if the utilities are off.  

Inspection needed because if this drains into septic than septic field is almost guaranteed to need replaced because of the oil and other contaminants going into leach field.

The agent put in the MLS that the land had contamination and wouldn't qualify for financing.

In the case of the SFR, it was replaced with a above ground tank.In both cases, the service has to certify there is no contamination, when done, you are in the clear.

Another bad news: The water damage company billed us $6,000 for extracting water, dry, the only thing they yet to do is to remove contaminated floor, dry wall.

With over 8 years of experience, Brian has successfully managed some of O’Neill Properties’ most challenging projects including a 400 acre radioactively contaminated former industrial site in northern New Jersey.

Secondly, make sure you get an inspection before you are locked in as I have walked away from houses that had extreme repair costs for specific items (10k and more per issue) due to: Failing septic system, mold remediation, methamphetamine contamination, dry rot.

The levels are fairly high levels but based on the environmental consultant probably did not include manufacturing just contamination from heavy use via smoking. 

I had the lack of a backflow preventer come up on an inspection report recently for a single family residence- I admit I'd never heard of such a thing, but it keeps potentially contaminated water from outside from siphoning back into the domestic plumbing system. 

You need to worry about environmental contamination, illegal dumping next to the gas station over the years, and leaking of gas tanks.It doesn't matter who caused the contamination the EPA will make the current owners clean It up.If it's a new build the seller should have a phase one completed on the land.
