Costner's is a small Stuart pocket in Martin County, and the current MLS snapshot is thin — no community amenities are identified, and there's no reliable median to hang a number on. That means pricing here is driven almost entirely by the individual property: lot, condition, and how it stacks up against the broader Stuart market rather than any community premium.
For a buyer, that puts the burden on comparables outside the immediate name. For a seller, it means your home's specifics — updates, siting, and turnkey condition — do the heavy lifting, since there's no amenity story or brand cachet doing it for you. In a market this narrow, individual negotiation matters more than any headline stat.
Figures in this note are as of July 20, 2026. The live market numbers elsewhere on this page update nightly and are newer.

The 60-Second Overview
Costner's is a small named community in Stuart, Martin County, without identified shared amenities in the current listings — the kind of place where the house and the location, not a clubhouse or gate, define the deal.
Pre-construction details are compiled from public records, builder announcements and builder listings, and are subject to change without notice; figures are deemed reliable but not guaranteed. Momentum Research figures are our own analysis. This page describes homes, pricing and community attributes, not residents.
Who Costner's is best for.
Best for
- Buyers targeting a specific home in Stuart who don't need shared amenities
- Value-focused buyers willing to underwrite on condition and comparables
- Owners planning to hold and improve a single property over time
Probably not for
- Buyers who want a gated or amenity-rich community
- Anyone needing a deep pool of active listings to compare within the community
- Buyers who want a turnkey lifestyle package rather than a standalone house

The Costner's buying strategy.
If we were buying in Costner's today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Move deliberately, not desperately. Neither side has a decisive edge, so a well-prepared, fairly-priced offer wins without overpaying.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in Costner's.
A property-driven pocket
With no community amenities surfacing in current MLS data, Costner's is best understood as a location within Stuart rather than a self-contained lifestyle package. What you're buying is proximity to the broader Stuart and Martin County coastal setting, plus the specific merits of the individual home.
That structure cuts both ways. There are no HOA amenities to underwrite, but there's also no built-in draw beyond the property itself, so condition and pricing discipline carry the outcome. Treat each listing on its own terms and lean on wider-area comparables to sanity-check value.
The location and the amenities are priced into every listing in Costner's. The deal is won or lost on condition, the comps, and the renovation math.

Martin County approves limited-industrial zoning on Southeast Powerline Avenue in Hobe Sound
Commissioners voted 3-2 to rezone a property along Southeast Powerline Avenue to limited-industrial, a less intensive class than the general industrial designation first proposed. The county said the existing zoning was outdated and that no data center is planned. Any proposal over 100,000 square feet would need board approval.
