Client reviews.

★★★★★

Mario closed our Banyan Tree skyhome twelve percent under list. He spotted the seller's leverage point that three other brokers had missed. The single best property hire we have ever made.

We had three weeks before school enrolment. Mario closed it in three weeks. The unit, the school placement, the visa paperwork. He had everything queued before we landed in Phuket.

First broker who actually understood what a family office needed. Off-market access, real numbers, no upsell. Closed three units with Mario in eighteen months.

Replied in fifteen minutes on a Sunday morning when I needed to move a deposit. That kind of presence is rare. Worth every basis point of the commission.

Honest about what was a bad investment. Talked me out of a beachfront unit that had a structural issue he had heard about from the developer side. Saved me eight figures of regret.

Bought, sold, then bought again with Mario. Each time the same level of detail. He treats every deal like it is the only one on his desk that week.

Spoke German with my wife, English with me, and Arabic with the developer. Closed the deal in a single call. That is the level of access you get with Mario.

Two years post-handover and he still picks up. When my building had a maintenance issue, Mario coordinated with the developer directly. That is unheard of in this market.

I have used brokers in London, New York, and Hong Kong. Mario operates at the same level. He just happens to do it in Phuket.
