In 1976, developers constructed an expansive multifamily oceanfront building on a spectacular real estate footprint at 6423 Collins Avenue, North Beach, Miami. It featured 150 linear feet of Atlantic Ocean frontage with an 18-story medium-rise tower containing 151 units. The enclave offers 1278 to 4,351 square feet under air (UA) floor plans—one- to four-bedroom models with up to 4.5 bathroom accommodations—with the promise of an incredible coastal-style lifestyle.

Mar Del Plata condos for sale feature sensational outlooks that include stunning streaming yacht spectacles from the upper floors with a westerly exposure and eye-popping expansive ocean views for the many residents with easterly perspectives. Finally, all residents relaxing on their renovated glass-panel terraces—fronting wall-to-ceiling high-impact sliders and windows—benefit from eye-popping city night lightscapes in several directions, flourishing tropical foliage, and manicured campus lawn vistas.

Snowbirds, retirees, local families, and well-heeled buyers from out-of-state locations invest in Mar Del Plata (versus other Miami condos not matching its features) to participate in the umpteen nearby restaurants, bars, delis, and supermarkets left, right, and center. Then, Mar Del Plata occupants can drive in minutes to Aventura Mall and Bal Harbour Shops for extraordinary shopping experiences and Miami South Beach for vibrant entertainment. The same goes for  Sunny Isles Beach, pickleball venues, excellent schools, golf courses, museums, the Miami International  Airport, clinics,  and other new urban lifestyle conveniences.

Some of the Mar Del Plata condo residents have gone the extra mile to remodel, attracting prospective buyers with newly installed custom cabinetry, premium stainless steel appliances, granite countertops, sleek wood or porcelain flooring, seamless glass showers, and more. Still, others offer marginally or zero upgraded units on the MLS, leaving renovation options open to those who want to create their own interior masterpiece.

Monthly HOA fees of approximately $0.78 per square foot of condo ownership (UA) buy everything one needs for peace of mind and stress-free leisure. The amenities and services include building insurance, elevator maintenance, and a consistently manicured campus. Moreover, exciting benefits emerge from private beach access steps from the lobby, a gorgeous heated swimming pool (seaside with a sundeck, umbrellas, and loungers), and a social-centric clubhouse with entertainment, media, and billiards rooms.

Finally, Mar Del Plata condo owners enjoy BBQ and picnic spots, walking trails, 24/7 guard-gated security, lobby attendance, a well-equipped cardio plus weight-fitted fitness hub, allocated covered parking, and a liberal leasing policy.
