Homes for Sale in Madeira Beach, FL
True comps, carrying-cost math, and listings before the portals.
As of September 2026, Crystal Island Add in Madeira Beach, FL has 1 home for sale. Over the 12 months ending 2026-09-12, 4 recorded sales closed at a median of $875,000, $543 per square foot, a median 175 days on market, sellers accepting 91% of original asking. Homes listed or recently sold were built 1960–1966. At the median price and Pinellas County's FY2025-26 rate of 19.39 mills, annual property tax runs about $16,960 ($16,150 with the full homestead exemption).
Price here is driven by the lot and the water, not the house. The median home is a modest 1,927 square feet built around 1962, yet the median sits at $900,000 and roughly $554 per square foot. That premium is location and land, and it means condition and renovation status swing individual sales more than square footage does.
The market posture right now favors patient buyers. The median list is spending 48 days on market, and the year-over-year median is down 25% across a thin window of three closings. That drop reads as a reset off a peak more than a signal about any one address, but it gives buyers room to negotiate and tells sellers to price to today, not to last year.

🟡 Balanced market. 3.0 months of supply and 0% of the inventory already under contract put buyers and sellers on roughly even footing.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 Stellar MLS records, as of September 12, 2026. Confidence: Low (1 active and pending listings, 4 closed sales in 12 months).
What's unique here: the median sale price is about 2x the typical Pinellas County sale ($875K vs $395K, trailing 12 months, Stellar MLS records).

Who Crystal Island is best for.
Best for
- Buyers targeting a water-oriented lot who can budget for updates on a 1960s-era home
- Long-hold owners comfortable with a small, established enclave rather than new construction
- Cash or well-qualified buyers ready to move on limited inventory when the right lot lists
Probably not for
- Buyers who need a large, modern floor plan well above the sub-2,000-square-foot median
- Anyone wanting a deep pool of recent comps to justify an offer
- Buyers seeking a fully turnkey home with no renovation appetite

The Crystal Island buying strategy.
If we were buying in Crystal Island 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 Crystal Island.
Land value over living space
With a median year built of 1962 and a median footprint under 2,000 square feet, much of the inventory is original or lightly updated. The high price-per-square-foot tells you buyers are paying for the setting and the potential, which is why you should expect a wide spread between tired homes and reworked ones. Underwrite the renovation, not just the asking price.
The closing window is only three sales, so the median is a snapshot, not a trend line. Treat the down-25% figure as context for negotiation rather than a precise measure of any single home's worth. On a street like this, the specific lot, elevation, and water access matter far more than a neighborhood average.
The location and the amenities are priced into every listing in Crystal Island. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
Thin data cuts both ways: with only three recent closings, a bad comp or a stale list price can cost you real money. We pull the individual sales apart by condition, lot, and water position so you are negotiating from what a specific home is worth today, not from a headline median.
