My experience has been that custom homes dont necessarily hold value better. They tend to be built more specific to the desires of the original owner and become functionally obsellete quicker. They also tend to be more expensive and that in and of itself is detrimental to a higher appreciation rate. Its all about location. Beach houses appreciated more and happen to be mostly custom builds. If they threw tracts on oceanfront lots in the 60’s and 70’s you would see higher appreciation also
