The number that anchors Cumberland Harbour right now is the 121-day median time on market. That is a slow clock, and it tells you pricing discipline matters more here than in a community where homes move quickly. A median price of $625,000 against a median of $299.48 per square foot points to a mix of home sizes and conditions rather than a uniform product, so comparable selection has to be tight.
With only 17 closings in the window and prices down 1.6% year over year, this is a thin, slightly softening market rather than a trend in either direction. Sellers should expect buyers to negotiate on days-on-market leverage, and buyers should expect that a well-priced, well-presented listing can still separate itself quickly from the rest of the sitting inventory.
Cumberland Harbour right now
🟢 Buyer-leaning market. 7.7 months of supply and 0% of the inventory already under contract give buyers above-average negotiating leverage.Why it matters: months of supply is how long today's inventory would last at today's sales pace; under-contract share is the portion of homes for sale that already have a buyer.Momentum Research analysis of ScoutMLS® records, as of September 3, 2026. Confidence: High (9 active and pending listings, 17 closed sales in 12 months).
🟡 Off the recent peak. The trailing-12-month median ($625K) is down 1.6% from the prior 12 months ($635K). With about 4 sales a year, a single closing can swing this number, so read the level and the decade, not one year's move.Momentum Research, record-level ScoutMLS® closed sales, 12-month windows ending September 3.

Who Cumberland Harbour is best for.
Best for
- Buying with flexibility on closing timeline given the market's slower pace.
- Negotiating hard on price where the 121-day median favors buyer leverage.
- Willing to independently verify community features before committing.
Probably not for
- Needing a documented amenity package confirmed before making an offer.
- Expecting a fast sale timeline in a market averaging four months on market.
- Relying on a handful of recent sales as a firm pricing benchmark.

The Cumberland Harbour buying strategy.
If we were buying in Cumberland Harbour 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 Cumberland Harbour.
A market defined by patience, not scarcity
At 121 days median time on market, Cumberland Harbour is not a fast-turn community. That number reflects a market where buyers have room to be selective and sellers who price ahead of the data tend to sit. The small closings count — 17 in this window — means each transaction carries more weight in shaping perception of value, so relying on a single recent sale as a benchmark is risky.
The median price of $625,000 and the per-square-foot figure of $299.48 together suggest a spread of home sizes and finish levels rather than a narrow, uniform product line. A slight year-over-year pull-back of 1.6% is consistent with a market working through inventory rather than one under pressure. Because no specific community amenities are showing up in current MLS listings, anyone evaluating a purchase here should verify what is and is not included — private access, common areas, or association features — directly rather than assuming a standard package.
The location and the amenities are priced into every listing in Cumberland Harbour. The deal is won or lost on condition, the comps, and the renovation math.
