True, but small condos have seen similar appreciation

This do increase the price of real estate, but not that much relative to the bigger picture. The price of a "glitzy" fridge vs. a non glitzy fridge is going to be what, $500? $1,000? Likewise, appreciation has occurred on older properties without these features unless you're below the inflection point where the risk of the property declining in value faster than the market appreciates is so high that the price remains poor.
