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 November 12, 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 12.0 months of supply, a buyer-leaning market. The trailing-12-month median is down 10% from the prior 12 months and up 125% since 2012, computed from record-level realMLS closed sales (10 closings in the current window).

In ZIP 32256 (Jacksonville), 809 homes closed in the last 12 months at a median of $405K ($215/sq ft), down 3.0% year over year, with a median 62 days on market. Right now 183 active and 54 pending listings put supply at about 2.7 months — a balanced market. See the live ZIP 32256 housing market and the Duval County market.

realMLS (Northeast Florida) sales records identify 381 homes in Summer Key Condos that have changed hands since 2007, built between 2007 and 2019 (median 2009), with a median living area of about 1,145 sq ft and a typical 2-bedroom, 2-bath layout; 100% are condominiums. Source: realMLS (Northeast Florida) closed-sale history compiled by Momentum Research; counts reflect homes with a recorded MLS sale, not every home in the community.

Flood zones in Summer Key: of 21 listing addresses checked against the FEMA National Flood Hazard Layer, 100% sit outside the FEMA Special Flood Hazard Area (Zone X). Individual parcels vary - verify any specific address at msc.fema.gov. See flood zones by neighborhood in Jacksonville.

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.

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.

If we were buying in Summer Key today, this is the order of operations we would run for our clients.

1

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.

2

Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.

3

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.

4

Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.

5

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.

Best Buy
Buyers prioritizing a lower purchase price in Jacksonville over unit condition or amenities.
Biggest Risk
Thin data — zero active listings and just 8 recent closings make comps harder to pin down.
Sweet Spot
Buyers who can work with a 119-day median marketing period rather than needing a fast close.
Avoid If
You need to compare several active listings before deciding, or you need a quick sale.

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.

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.

What it really costs to own in Summer Key

The parts of the monthly number a mortgage calculator leaves out, from the tax roll, the MLS, Citizens and FEMA. Property facts only.

Property taxAt today's median asking price of $170,000, the first-year bill with homestead is about $2,300/yr (Duval County total millage 17.865 mills, FY2025-26, Duval County Property Appraiser 2025 final millage chart; Duval County School Board FY2025-26 adopted millage).
HOA duesMedian $296/month across 13 MLS listings (most billed monthly; 2026-11-14). Dues cover what the documents say they cover; ask for the budget and reserve study.
Home and flood insuranceThe average Citizens Property Insurance premium in Duval County is $1,315/yr (2,001 policies, Citizens detail by county, April 2026); private-market quotes depend on roof age, wind mitigation and construction. Flood: of 21 listing addresses checked against the FEMA flood map, 100% sit outside the high-risk zone. Statewide, a Zone X flood policy runs about $500-$700/yr and a high-risk zone $1,200-$2,500/yr (FEMA Risk Rating 2.0 averages, not quotes).

Estimated carrying cost at the median asking price, before the mortgage: about $597/month (tax $192, HOA $296, insurance $110). An estimate from the sources above, not a quote.
