622 S. Miami Ave. (J. Albert Diaz)
Address: 622 S. Miami Ave., Miami
Property type: 5,683-square-foot, two-story warehouse built in 1920 on a 7,500-square-foot lot. Currently zoned for mixed-use residential.
Price: $3 million, or $400 per square foot
Seller: Espinosa Properties LLC, linked to Victoria Espinosa, who bought the property in 1972
Buyer: Tobacco Road Property Holdings LLC, managed by auto dealership mogul Carlos Mattos
Past sale: $24,900 in November of 1972
Background: In April 2012, Mattos bought most of the property in the triangular block just north of the Brickell CityCentre site. Back then he paid $251 per square foot for the 49,000-square-foot assemblage, which excluded two lots on the triangle’s north corner and one lot in the west corner. Mattos still does not own two of those corner lots—one belongs to the State of Florida, the other is the property of a Surfside investor with other land holdings in the area.
