Here's a shocking story of a life time. Link:http://realestate.aol.com/blog/2011/06/20/real-estate-disclosure-what-you-dont-know-can-hurt-you/?icid=maing-grid7%7Cmain5%7Cdl3%7Csec1_lnk2%7C71747
Let me tell you something. Landfills are good for keeping trash away for good. But you know what? When a landfill is full and capped, it's sometimes turned into a housing unit area on top of it!
I know one area in my former hometown I lived in the Rochester, NY area. But for legal concerns, I'm not disclosing it's location. I do know that certain area was a massive land fill long ago. Then it was capped. Then a apartment complex was built RIGHT OVER IT! To this day, people have a lot of problems living there, from the rats to major health problems.
If you are going to buy a home, you better make sure it's a neighborhood that's been established for a long time, like 50 years. A place that has a garbage down under, it's like unearthing major problems in which some one's going to be asking a lot of questions of just how it got there!
So, when you buy a home, dig in several spots down to make sure it's not sitting on a landfill or something worse (like a nuclear storage spot). This is something that we all don't need to fear of owning a home.
