A company tied to Miami spec home developers Sergio and Fernando Guardazzi paid $5.2 million for a waterfront house in Key Biscayne.

The Guardazzis bought the 4,900-square-foot house with an attached guest house at 220 Island Drive for $1,061 per square foot, records show. Delphia Enterprises, which lists Rodrigo Ernesto Avila Alvarez as a manager, sold the property.

Built in 1961, the home has three bedrooms and three bathrooms, while the attached guest house has two bedrooms and two bathrooms.

The property has 160 feet of water frontage and sits on a 20,840-square-foot lot. It was last purchased in 1976 for $275,000, records show.

The seller was represented by Brigitte Nachtigall with Great Properties International. The buyer was represented by Alex Lipzer with Key Biscayne Realty Group, Inc, according to realtor.com.
