18683 Collins Avenue, Miami, Florida | Neighborhood: Sunny Isles Beach
What you are actually buying
Counted against the Miami-Dade County Property Appraiser record on 17 August 2026, this building returns 234 folios: 210 residential homes and 24 commercial. That commercial count is the tell — this is a condo-hotel, and the hotel operation occupies its own separately-folioed space within the building.
The county registers the subdivision as “M Resort Residences Condo”. If you go looking for Marenas in public records, that is the name to search.
Heated area runs 688 to 1,497 square feet, with a median of 688 — meaning a majority of the building is the smallest floorplate. The mix is 126 one-bedrooms and 84 two-bedrooms, with nothing above or below.
The 2026 median assessed value is $464,186, which for oceanfront Sunny Isles is genuinely accessible.
Steady pricing, thinning volume
Qualified sales from the county record — arm’s-length only.
| Year | Qualified sales | Median price | Median $/sq ft |
|---|---|---|---|
| 2023 | 18 | $595,000 | $814 |
| 2024 | 7 | $680,000 | $923 |
| 2025 | 6 | $640,000 | $856 |
| 2026 to date | No qualified sales recorded | ||
Per-foot pricing of $814 to $923 is high relative to the modest ticket price, which is characteristic of condo-hotel product: you pay more per square foot for a smaller unit because the rental programme, not the floor area, is the product.
The volume trend is the thing to watch. Eighteen qualified sales in 2023, then seven, then six, then none recorded so far in 2026. That is a sharper drop than the surrounding Sunny Isles market, and it means there is currently no in-building comparable.
Who this suits
This suits a buyer who wants oceanfront Sunny Isles at an accessible price and intends to place the unit in the rental programme. That is the proposition, and the small floorplates make sense in that light.
It suits an owner-occupier less well. A 688 square foot median in a building with a working hotel means transient traffic, and it is not a quiet residential association.
Before buying, get the rental programme terms in writing — the operator split, how nights are allocated, what the owner’s personal-use allowance is, and what happens if the operator changes. Those terms determine your return far more than the purchase price does, and they are not on the public record.
