Upgrades to a model can easily exceed $75K but i havent seen either home. As for overlooking a community park/open space. I’d rather face that than another house 10 feet out my back window but you are missing the point. I’m just pointing out that you analysis was flawed. Here’s the other possibly even bigger flaw. The house sold at 625 and you are comparing it to a house on the market with a 550 to 599 value range. You are assuming it will sell at the bottom of the range. It might and it might not, but I’d bet the seller is looking for 575 to 599 right now. Will he get it….who knows?
As for Zillow…it stinks right now. Hopefully it will get better. It has my house $200K below what it would sell for today. if I put the Zillow price on my house I would have at least 50 offers in a week…guaranteed!
