Sorry, I don’t have detailed info about the inventory. I am familiar with the development and I scan the MLS for builder and flipper units, but haven’t set foot there in about a year.
All floor plans are very similar, and about the same size. Don’t be fooled by the 2-bdr, 3-bdr, and 4-bdr designations. A bedroom can become an office can become a loft if a wall is knocked down or a closet added. That’s pretty much all the difference among various units. I think the largest floorplan is only about 5% larger than the smallest (they average about 1,500 sq ft).
In any case, Airoso is part of the Pacific Highlands Ranch master planned community north of 56. Further north-east, you have Del Sur, and then 4S Ranch even further away. All these projects have a mix of housing, from rentals and townhomes at the low end, up to tightly packed McMansions at the high end.
I personally am looking for SFHs in the 2,000-2,500 sq ft range, but am keeping an eye on the entire market, just in case.
