Facts are, we that are natives and are investors and realtors know the real deal and we would not buy in SINK HOLE ...BFE... Spring Hill!
We all know its best to avoid that whole sinking area north of here!
N. Rose: The reality is that the area has been plagued with "sinkhole claims" - not necessarily as plagued with factual sinkholes. Here in FL, we are built on sand, there is no granite basin beneath our grounds, like found in many parts of the Midwest, etc. That being said, a concrete slab is poured as the foundation of our homes in most instances here, and it's susceptible to cracking (due to the shifting ground beneath). This shifting (also known as settlement) is quite typical, and is found in a large portion of the homes throughout ALL of FL, not just Hernando County.
What we saw happening recently was a large portion of "get rich quick" contractors, who were recently out of work from the housing collapse (no more new construction, renovation projects, etc), begun to open up "Sinkhole Repair" companies. They'd help homeowners make a claim against their insurance policy and get paid tens of thousands of dollars to "remedy" the settling. Once this process is done, the home is now a "Settlement Repair" home and is part of the "Sinkhole Stigma" locally. This was done widespread, and is nothing short of insurance fraud on behalf of the contractors who were involved.
Not to say that the area does not have sinkholes, because clearly it does. However, it would not be prudent of you to purchase a home without having all the proper inspections completed - including, but not limited to, a structural inspection & possibly an engineering report if there is suspected settlement damage.
Good luck & hopefully this helps you in your quest for an answer!
