18683 Collins Ave · Built 2005 · 45 floors · 210 residences

Marenas Beach Resort is a waterfront tower of 45 floors and 210 residences at 18683 Collins Ave in Sunny Isles Beach, developed by Tangiers Beach Associates and completed in 2005. The Property Appraiser records it as M Resort Residences Condo.
On the 2025 Florida tax roll, 0% of the 210 units carry a homestead exemption, and 83% are owned by a company or trust. The Miami-Dade Clerk recorded 2 resale deeds in the 12 months to October 21, 2026. Financeability is in the limited tier, at 39 of 100, meaning few recent purchases here were financed by regulated lenders.
The building sits in FEMA flood zone X, a minimal risk area where flood insurance is not federally required but is available. It is in Miami-Dade hurricane evacuation zone B, and the lowest street beside it is 2.7 ft above the highest tide predicted for 2026 at Virginia Key. A Publix is 390 m away in a straight line, and the nearest rail station, Aventura Brightline Station, is 2910 m (about 1.8 miles) away. The Car-Free Index is 6. There is 1 active tower construction site within 500 m, which can bring noise and traffic while it lasts.
