Adding a home warranty to your listing adds confidence and might result in someone purchasing your home over a newer home. Many people are nervous about old appliances and fixtures, etc.
Buyers are much more comfortable with a house that includes a one year warranty.
The warranty can be promoted in the advertising as a drawing feature of the home. Competitive Edge over similar homes not offering a warranty. Reduces after-sale problems. Pay at closing. There is no charge to the Seller until closing.
