Can you tell if this home is vacant? With the times as they are in the area there are many professionals that had to be relocated for their jobs forcing people to leave their homes and hope they sell. In many cases the owner is stuck with two house payments and would love the opportunity to simply get out of their previous home while they can. There are also a lot of estates that are full of physical work for the families to go through the belongings left in the home. Many people with family estate homes are letting them sit or not cleaning them properly in order to sell. Most of these older homes need TLC and simply aren't priced accordingly. If a home has been vacant on the market for four years there has probably been the oportunity for critters to enter the home. A thorough home inspection is necessary.
