Spending $300 to $500 to offer buyers a warranty with your home is a sound investment that's likely to pay off big. Among the major concerns buyers have about resale homes is whether their systems--heating/cooling, electrical, appliances--are in good working order. Offering a home warranty assures buyers they'll be protected from large cash outlays should a malfunction occur after they take ownership.

The payoff? You're likely to receive more purchase offers. The more buyers there are competing for your home, the higher your final contract price will be.
