Phanpd - I think in general the pricing has gone up on these homes, especially plan 2's. Plan 2's have been selling out the day they're released. I believe they're on phase 13 now? Certain phases have premiums built-in to the homes (view, lot size, etc). I just checked Shea's site and it looks like the plan 2's are starting at 654k, so I'm assuming there's a huge lot premium. I purchased phase 9, the lot I initially wanted sold for 12k more due to the lot being 800 more sq ft. I have a pretty standard lot, I do believe it's a big bigger than the original releases, my lot is 3,500 sq ft. We paid 614,900.
I know they were building certain phases where there are only 3 homes (with huge lots) as opposed to 6 homes. Check the sq footage out, if you PM me I'll give you my cell and answer any additional questions you may have. Good luck!
