How many sales have you had so far? I can see the "DVD player" logic working for DVD player, cars and other possessions that are expected to lose value over time but I don't see this working for real estate and other assets that are commonly seen as investments (Whether they are income-producing or not).
Regardless of which area you're building in, the bottom line seems to be that I'd pay $400k this year for something I could get for $225k next year. Whether I'm in KC and it's worth $220k or Bay Area and it's worth $1.6mil I'm still immediately losing $200k at the time of purchase for no benefit other than having the property a year earlier.
