Pricing at Onyx on the Bay is currently anchored by a median of $675,000, with price per square foot running at $509.30. That per-foot figure suggests condition and finish level are doing most of the work on value here — this is not a market where every unit trades in a tight band, it's one where the buyer willing to renovate and the buyer who wants turnkey are paying very different premiums for the same square footage.
A median days-on-market figure of 121 tells you this is not a fast-moving book of listings. Sellers should price with patience in mind rather than expecting a quick multiple-offer outcome, and buyers have more room to negotiate on terms and timeline than they would in a market where units clear in weeks. With only 7 closings in the current window, treat these figures as directional rather than a fully seasoned trend line.
Figures in this note are as of July 22, 2026. The live market numbers elsewhere on this page update nightly and are newer.

Price History: What Homes Here Have Actually Sold For

The Onyx on the Bay Condo buying strategy.
If we were buying in Onyx on the Bay Condo 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 Onyx on the Bay Condo.
What the numbers are actually saying
The median price of $675,000 combined with $509.30 per square foot gives a read on value, but the small closing count of 7 means this snapshot should be read as a current signal rather than a long-run average. A single well-appointed unit or a distressed sale can move these figures meaningfully from one reporting window to the next.
The 121-day median days-on-market figure is the more telling data point for strategy. It signals a building where pricing has to be right from the start — overpricing here doesn't just cost time, it compounds against a market that is already taking longer than average to absorb listings. Current MLS data does not identify specific community amenities, so buyers and agents should confirm building features directly rather than assuming.
The location and the amenities are priced into every listing in Onyx on the Bay Condo. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
With only 7 closings feeding the current numbers and a median days-on-market north of four months, pricing strategy and unit-level condition assessment matter more here than in a high-volume building. We track this data closely enough to know when a listing is priced to compete and when it's priced to sit.

What it really costs to own in Onyx on the Bay Condos for Sale
The parts of the monthly number a mortgage calculator leaves out, from the tax roll, the MLS, Citizens and FEMA. Property facts only.
| Property tax | Current owners' bills run a median of $8,869/yr across 6 listings here (MLS tax records, 2026-10-20). |
|---|---|
| HOA dues | Median $1,482/month across 6 MLS listings (most billed monthly; 2026-10-20). Dues cover what the documents say they cover; ask for the budget and reserve study. |
| Home and flood insurance | The average Citizens Property Insurance premium in Miami-Dade County is $1,891/yr (56,357 policies, Citizens detail by county, April 2026); private-market quotes depend on roof age, wind mitigation and construction. |
| Roof and age | Median build year 2007 across 6 listings. An original roof here would be about 19 years old; under Florida's 2022 reform (SB 2-D) carriers may require an inspection past 15 years, so budget for a roof report, and for replacement where it fails. |
Estimated carrying cost at the median asking price, before the mortgage: about $2,379/month (tax $739, HOA $1,482, insurance $158). An estimate from the sources above, not a quote.
