KEYSTONE T/H
Homes for Sale in Mary Esther, FL
True comps, carrying-cost math, and listings before the portals.

Keystone is a small townhome pocket in Mary Esther, and price here is driven by condition and unit specifics far more than by any headline figure. The median sits at $223,000, but with only three closings in the window, that number is a rough marker rather than a precise gauge — one updated versus dated unit can move it meaningfully.
The posture is slow. A median of 156 days on market tells you these units are not clearing quickly, which hands patient buyers real negotiating room. Sellers should price sharply from day one and expect the process to take time; anything overpriced will sit.
The 60-Second Overview
KEYSTONE T/H market snapshot (as of July 25, 2026): the median sale price is about $223K, and a median 156 days on market for closed sales.
Keystone T/H is a modest townhome community in Mary Esther, Okaloosa County, where the story is a low transaction count and a slow-moving market rather than amenities or scale.

Price History: What Homes Here Have Actually Sold For
Median sale price over the trailing 12 months ending July 25 of each year, from record-level emeraldcoast closed sales. Same methodology as every appreciation figure on this page: the 2026 point ($223K) IS the median in the snapshot above.
Windows contain 0 to 5 sales each (3 in the current window); every figure carries its sample size, and thin markets swing on single closings.

The real cost & risk here
Before the list price, the Florida math the portals skip. These are Okaloosa County typicals — your exact home, flood zone, and insurance quote will vary, so verify each before you offer.

The KEYSTONE T/H buying strategy.
If we were buying in KEYSTONE T/H 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 KEYSTONE T/H.
A thin, slow townhome market
With just three closings in the tracked window, Keystone trades infrequently. That thinness cuts both ways: comparable sales are scarce, so pricing leans heavily on the condition and layout of each individual unit rather than a deep pool of recent data.
No community amenities turned up in current MLS listings, so value here rests on the townhomes themselves and on Mary Esther's location within Okaloosa County. A median of 156 days on market underscores that buyers have time to evaluate and negotiate, and that sellers need to lead with a credible price.
The location and the amenities are priced into every listing in KEYSTONE T/H. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
In a low-volume community like Keystone, a handful of sales sets the tone, so reading condition against the median matters more than chasing a comp. We help buyers use the slow 156-day pace as leverage and help sellers price honestly so a unit does not languish.
