Welcome to Key Biscayne

As founder of Urdapilleta Real Estate, her office is strategically located in the heart of Key Biscayne, within one of its main commercial galleries—providing constant, direct access to both inventory and real-time market movement.

Key Biscayne operates as a highly constrained micro-market where limited supply, strong end-user demand, and strict zoning regulations define value. Pricing is driven by very specific variables—line, exposure, floor height, renovation level, and positioning within each building—making local expertise essential.

With deep market knowledge, strong relationships, and access to both on-market and off-market opportunities, Dolores Urdapilleta positions each transaction with precision—whether buying, selling, or renting.

From luxury waterfront homes to high-end condominiums and investment assets, the focus is clear: maximizing value through strategy, market insight, and execution.

In a market like real estate in Key Biscayne, experience and positioning make the difference.
