Mattamy At Southern Grove is a small-footprint builder community in Port St. Lucie where the median sale closed at $449,900 and homes moved in just over two months; the year-over-year price decline of 8.2% reflects broader St. Lucie repricing rather than project-specific distress.

Mattamy At Southern Grove sits in Port St. Lucie, where the story is straightforward: this is a builder community offering new construction at a median of $449,900 and $225 per square foot. The 8.2% year-over-year decline is consistent with the county-wide correction; it does not signal project failure but rather the end of the spike and a return to more measured pricing. Three closings in the trailing window suggest either a new phase or limited inventory, so if you are shopping here, expect fewer choices and less negotiating leverage than in a mature resale neighborhood.

MLS data shows no identified community amenities—no pool, no clubhouse, no trails listed in current offerings. That means you are buying the home itself: Mattamy finish, builder warranty, and the ability to walk into a turnkey product without renovation. The 62-day median time on market is neither fast nor stalled; it reflects a market where buyers are deliberate and builders are no longer seeing bidding wars. If your priority is new construction in Port St. Lucie and you are comfortable with a utilitarian community envelope, the pricing here is rational. If you expect resort-style common areas or a deep sense of neighborhood, keep shopping.

Mattamy At Southern Grove is a builder community, and builder sales teams work for the builder—not for you. Momentum represents your interest: we read the purchase agreement for upgrade caps and delivery timelines, we compare the builder's pricing against resale comps in Port St. Lucie, and we tell you when the premium for new construction is justified and when it is not. In a market down 8.2% year over year, that independent analysis is the difference between a sound buy and overpaying for newness. We know St. Lucie County, we know Mattamy's product and contract terms, and we will walk you through the decision without the sales pressure.
