Quietly or not, writing a check for about $14.9 million will always get noticed in Coral Gables. MasTec CEO Jose Mas has bought a roughly one-acre waterfront lot at 9175 Arvida Parkway inside the ultra-private Gables Estates enclave, clearing the way for a new mansion and adding one more eye-popping land trade to the neighborhood’s recent run of big-ticket waterfront deals.
Deal details
As reported by The Real Deal, Mas, the CEO of MasTec and a co-owner of Inter Miami, paid $14.9 million for the Gables Estates parcel at 9175 Arvida Parkway. Property records identify the seller as a company led by developer Humberto Ramirez, whose LLC had picked up the site for $10.4 million in 2023. Ramirez co-listed the lot with Eddy Rengifo, and he said that Roxanna Urban of One Sotheby’s International Realty represented the buyer. Ramirez also told The Real Deal that Mas has tapped architect César Molina of CMA Design Studio to design a new mansion for the property.
Lot specifics and listing history
Listing data show the parcel spans about 0.99 acres with canal frontage, a seawall and ocean access, and it was brought to market at $14.9 million. Realtor.com and local MLS records indicate the property hit the market late last year and went under contract earlier this year. The listings also flag six-figure annual tax bills, a reminder of just how high values run inside this corner of Coral Gables.
Mas family buying spree and local market
Mas’s latest buy slots into a broader pattern for the family at the very top of Miami’s luxury market. Jorge Mas recently flipped a large Coconut Grove waterfront parcel for more than $100 million in a deal tracked last year, a headline-grabber even by Miami standards. The Real Deal has chronicled several of the family’s high-profile moves. On the broader market front, local data point to persistent strength at the luxury end of Coral Gables. Douglas Elliman documents active high-end single-family sales and ongoing momentum in the city, conditions that help explain robust demand for prime vacant waterfront parcels like Mas’s new lot.
What comes next
With architect César Molina already linked to the project, the logical next steps are design work and permit filings, although no public construction timeline has surfaced yet. Molina’s name has appeared on permitted plans and listings for other recent Gables Estates properties, reinforcing a local trend of pairing vacant waterfront land with marquee architects. Listings from Brown Harris Stevens show Molina connected to other high-end plans in the neighborhood, suggesting Mas’s new build will likely fit right into the enclave’s escalating arms race of custom waterfront estates.
