Any home may have hidden issues that if not uncovered can cost you a lot in the long run. Older homes may have suffered from excessive wear and tear or neglect. Newer homes may have quality issues that should be corrected by the builder before you take possession.
If you're buying, eliminate any unpleasant surprises before you close. If you're selling, sell faster and get your asking price by assuring potential buyers of the health of your home.
Whatever the case, be sure you're making the right decision by having your home inspected by Forensic Home Inspections.
