Before purchasing a new property, buyers should have the property thoroughly inspected. One inspection that is standard is a pest inspection. It's recommended that buyers are present when the inspection is being done so that they can ask questions. Some buyers prefer to spend several hundred dollars on other inspections including structural inspections, roof inspections and electrical inspections to make sure that the property they're buying doesn't have problems lurking in the future. People who don't have these inspections done sometimes end up in long, costly lawsuits against the seller for the costs of repairs. The law states, however, that a seller isn't liable for problems that weren't known to them at the time of the sale. Since most homeowners don't normally have their property inspected on a regular basis, sellers often won't know about potential problems such as faulty foundations, which can cost as much as Fifty Thousand Dollars to repair. For this reason, buyers are encouraged to have properties inspected thoroughly before the sale is finalized.
