A home inspection answers one crucial question.
"Is this house worth the investment?"
Home inspections are used to provide an opportunity for a buyer to identify any major issues with a home prior to closing. Your first clue that a home inspection is important is that it can be used as a contingency in your contract with the seller.
This contingency provides that if significant defects are revealed by a home inspection, you can back out of your purchase offer, free of penalty, within a certain timeframe. The potential problems a home can have must be pretty serious if they could allow you to walk away from such a significant contract.
