Not Irvine, but an interesting case study that readers may find of other new build properties in Irvine.

Builder sale of model home Oct, 2018 - $1,560, all cash, no loan.
Resale of home May 2021, $1,580, all cash, no loan.
New list for sale January 2022, $1,780.
In the sale history to present day, you can see the same furniture, staging in bathrooms, etc from model build (2016?) to 2022. These aren't re-used photos as the lighting and angles have changed. Not an appreciation play as price growth doesn't fit the WTF category, but IMHO the home seems to be on a high rotation spin cycle for cash washing.
