Nearly EVERYONE prefers a 'never lived in before' home. (+$40,000)
Most builder grade accessories have a 10 year life expectancy. A five year old home is at half life. (-$5,000) to (-$25,000) based on product and number of items (pool, spa, materials, etc) and whether the house was lived in hard.
All of this is highly deceptive and completely not actionable by the typical consumer who seeks a simplistic answer. It is simply not that easy.
What you need is to have your REALTOR complete a CIS Score of the re-sale home.
