These homes are clearly overpriced but some buyers a desperate to get in the market now as inventory is low, prices of preexisting homes and interest rates have been going up. I wouldn’t be surprised if this is another bubble which will burst within the next couple of years.
I also believe that these models are misleading in the sense that they make them look bigger than in reality. When you drive by the homes under construction you can see that they are being built close to each other with almost not space between them.
