An exceptional chance to acquire or develop a classic Mediterranean gem in Miami Beach that seldom becomes available. This property is situated in one of the most sought-after areas of Miami Beach and offers fantastic access to the Julia Tuttle Causeway. The property necessitates a complete renovation since it has not been updated for more than three decades. Initial quotations from general contractors range from $400k-$500k for a mid-modern refurbishment. The roof is only ten years old and still has plenty of life left. This property has boundless potential, and it would be a mistake to overlook this opportunity to own a timeless Miami Beach classic.
