brand new home in the high 800k range. sold in mid 2001. which means construction started in late 2000, which probably means the sales price was negotiated back in mid 2000, so the high 800k price was 2000 pricing.
Now, the lot premium as well as the increase in size likely would account for a $150k premium on the price. So you take $870k and minus that and you get $720k.
$720k and add all of the after market upgrades this house has and you get $880k.
what you have shown with Castello is that these homes are of the same quality as Avaron, as Castello at peak pricing was $1.7 million, and the average new homes in Avaron was around $1.4 to $1.5 million. Those new homes, after upgrades, then realistically would be at the same pricing. So you can extend that and say most Avaron homes brand new at 2000 pricing would be around the $800k range. But This home in particular, because it is what it is, would be in the $700k range. However, adding all of the upgrades, mid $800k range would be a good price and quite frankly 2000 if not very close to it.
