The quality of construction in the older VP homes is pretty weak. Bathrooms are tiny and the neighborhoods have more riff raff than Summerhill. I also believe in getting more sq ft for the money even though they are attached.
If you had a couple kids and got stuck in a home longer than you wanted what would you rather be in. A smaller detached or a bigger attached home.
BTW, The 1745 SH floorplan is really nice also. It has 3 BR’s up and a great kitchen set up with a breakfast nook and private patio in front.
