Summer Key Condos in Jacksonville (Duval County) carries a median resale price of $156,000, or a median $145.46 per square foot, as of the July 11, 2026 snapshot. That is a lower entry point than most of the surrounding condo market, and at this price level the spread between a dated unit and a well-kept one shows up directly in what a buyer pays — condition and finish, not location premium, are doing most of the work on price here.
The current posture is thin. Active listings sit at zero, the recent window shows only 8 closings, and the median days on market is 119 — just under four months. Prices are also down 11.9% year over year. Put together, that is a market with very little live inventory to shop against and sellers should plan on a longer marketing period; buyers who are patient and comfortable pricing off recent closed sales, rather than an active board, have room to negotiate.
Figures in this note are as of July 14, 2026. The live market numbers elsewhere on this page update nightly and are newer.

The 60-Second Overview
Summer Key market snapshot (as of October 23, 2026): the median sale price is about $158K ($149 per sq ft over the trailing 12 months of closed sales), a median 59 days on market for closed sales, and 9.0 months of supply, a buyer-leaning market.

With zero active listings against a recent window of 8 closings, Summer Key is trading almost entirely on historical sales data right now rather than a visible, shoppable inventory.

Who Summer Key is best for.
Best for
- Buyers focused on a lower entry price who are comfortable underwriting from closed sales rather than a deep active inventory.
- Buyers with flexibility on timeline, given a median marketing period of about 119 days.
- Buyers or investors comfortable pricing off historical trend (up 137% since 2012) alongside recent softness (down 11.9% year over year).
Probably not for
- Buyers who want to compare multiple active listings side by side — there are currently none active.
- Sellers expecting a fast sale; the median days on market here runs close to four months.
- Buyers relying on continued short-term price momentum — the median price is down 11.9% year over year.

Loretto Elementary breaks ground on $12.3 million classroom addition
The addition will replace 13 portable classrooms and two aging pod buildings with 15 classrooms, a music room and a teacher planning room, and will expand the parent drop-off loop. The school enrolls 875 students for 2026-27. Funding comes from the voter-approved half-cent sales tax, with opening expected in 2028.
What it may mean for the marketExpanded permanent capacity and a longer drop-off loop affect school-area traffic and classroom availability in the Mandarin area. The project is about 5 miles southwest of Summer Key, elsewhere in Duval County.

JEA advances about $690 million in infrastructure projects including Fulton Cut transmission line raise near JAXPORT

Fulton Cut, shared with JAXPORT and the city, is expected to finish in summer 2027 and all four projects by 2030.
What it may mean for the marketRaised power lines support larger ship access to port terminals, and new reclamation capacity supports growth in surrounding areas. The site is about 10 miles north of Summer Key.

The Summer Key buying strategy.
If we were buying in Summer Key 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.
Use your leverage. With inventory sitting, there is room to negotiate on anything dated or overpriced and to ask for repairs or a rate buydown.
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 Summer Key.
A long climb, a recent pullback
Zoom out and the price history is not flat: value here is up 137% since 2012, a long-run climb that puts the current median of $156,000 in context — this was a materially cheaper community a decade-plus ago. Zoom back in, though, and the near-term trend has softened, with the median price down 11.9% year over year. Both things are true at once: a long upward cycle and a recent cooling, which is consistent with a market heat score currently reading 10 — on the cool end of the scale.
The practical issue for anyone transacting today is thin data. With no active listings and only 8 closings in the recent window, there is no live comp set to check a list price against in real time; pricing has to be built from the most recent closed sales. The median days on market of 119 tells the same story from a different angle — units here take time to sell, so a listing strategy needs to account for a multi-month timeline rather than a fast turnover.
The location and the amenities are priced into every listing in Summer Key. The deal is won or lost on condition, the comps, and the renovation math.
Momentum Buy Score.
Our proprietary 0 to 10 read across the factors that decide how a home in Summer Key buys, holds, and resells. Momentum Research; not an appraisal.
Momentum Intelligence Scores are our proprietary, qualitative assessment on a 0 to 10 scale, built from the record-level market data on this page. They are a framework for comparing communities, not a guarantee of future value and not advice on a specific home; unlike an automated value estimate they do not price your home, they grade the community on evidence you can inspect. Composite is the plain average of the 4 factors (4.0). Basis: Long-Term Appreciation +126% since 2012; Recent Direction -10.7% year-over-year; Liquidity & Demand 9.0 months of supply; Pricing Power 90.7% sale-to-list. Refreshed with each data update.
Why work with Momentum here
In a market with zero active listings, pricing a purchase or a sale correctly depends on someone who tracks closed transactions as they record, not a snapshot of what happens to be on the board. We build our read of Summer Key from the recent closed-sale window and the longer price history since 2012, and we hand-prepare the valuation rather than lean on an automated number — with only 8 closings to work from, that judgment call matters.
