Here is what this listing's numbers say about the builder's position.

• On the market 5 daysContext

  Still relatively fresh. Expect the sales office to hold firmer here than on inventory that has been sitting.

  A completed home with a Certificate of Occupancy is inventory, not a future sale. Builders treat standing inventory very differently from a lot they have not broken ground on.
