Private real estate advisory in Los Cabos since 2004.
Buyer and seller representation, market interpretation and negotiation — always on the client’s side of the table.
Valentino founded and led a private protection operation in Los Cabos serving high-profile individuals and families. The work required discretion, personal accountability and absolute respect for privacy — principles that would later become central to the way he advises private real estate clients. A faith-driven businessman, he brings those same values to every engagement.
Valentino entered the Los Cabos real estate market in 2004, spending his first decade within an internationally recognized real estate organization. Those years provided direct exposure to different market cycles, evolving communities and the development of Los Cabos into the luxury residential market it is today.
With a decade of market experience behind him, he founded VanSirius as an independent, owner-led advisory firm, working with private clients, buyers and sellers alike.
Understanding Los Cabos is not simply knowing what is currently listed. It is understanding why two apparently similar oceanfront properties can carry very different long-term values, why one homesite may be fundamentally more difficult to replace than another, and why the best decision is sometimes the property a buyer initially overlooked, or the decision not to buy at all. His experience spans established and emerging communities throughout Los Cabos, including Maravilla, Punta Ballena, Diamante, Cabo del Sol, Palmilla, Pedregal, Quivira and Puerto Los Cabos, among others.
The objective is not simply to find a property. It is to understand the client well enough to recognize the property that genuinely makes sense.Valentino Sartev
Valentino advises both buyers and sellers, and much of his career has been spent on the buyer’s side of the transaction. A listing represents a property. A buyer advisor represents the client.
Advising, not selling.
The principle behind every engagement, from the first conversation to the years after the transaction.
As Founder and Principal Advisor of VanSirius, Valentino works most often on behalf of buyers, and with the same discipline for the owners who entrust him with a sale: identifying the right property, understanding the nuances behind value, evaluating opportunities beyond the listing presentation, and negotiating from a position of knowledge, without pressure.
At the upper end of the market, buyers rarely choose on bedrooms, square footage or views alone, so the work begins with questions.
Los Cabos contains extraordinary real estate, but extraordinary does not mean appropriate for every buyer. A beautiful property may still be incorrectly priced, a prestigious community may not suit a particular family, and a property that looks understated on paper may be an unusually compelling opportunity.
The goal is not to show the greatest number of properties. It is to reduce the number of properties worth serious consideration.
Discretion, direct attention and independence define the relationship. Many of the most sophisticated buyers do not want attention surrounding their search or ownership decisions; VanSirius is a private firm, and Valentino remains personally involved from the first conversation to closing. Clients are not handed from department to department.
A small selection of distinctive properties reflecting Valentino Sartev’s experience representing buyers across oceanfront residences, private communities and significant Los Cabos acquisitions. His seller representation remains private.
Selected examples only, not a complete history. Certain transactions and client relationships remain private.
One of only five oceanfront homesites within a private enclave of Maravilla, itself one of Los Cabos’ most tightly held club communities. Defined not by land value alone but by scarcity, orientation, privacy and the difficulty of replicating the opportunity inside an established club environment.
Valentino represented the buyer in the acquisition.
Acquisition value: US $20,000,000. Oceanfront homesite, Maravilla, Los Cabos.
A turnkey oceanfront residence built and offered directly by the community’s developer and, at the time, the only completed custom home available within the enclave. Five bedrooms, with interiors by Lorena Vieyra of Vieyra Arquitectos.
Valentino represented the buyer in the acquisition, negotiated directly with the developer.
Developer list price: US $14,000,000. Press coverage of the property: Robb Report · Mansion Global.
An oceanfront villa within Las Residencias at Punta Ballena, with direct frontage on the Sea of Cortez and views to Land’s End. Five suites across three levels served by an elevator, on a 2,600 square metre oceanfront lot, fully remodelled and furnished, inside a gated community with beach club and spa.
Valentino represented the buyer in the acquisition.
Acquisition value: US $10,000,000. Oceanfront villa, Las Residencias, Punta Ballena, Los Cabos.
A beachfront villa set directly on Diamante’s Pacific beach, within the Beach Estates enclave of one of Los Cabos’ most recognised private golf and resort communities. Five suites, contemporary in style, with sweeping Pacific views. Part of Valentino’s broader experience within Diamante, across several product types in the community.
Valentino represented the buyer in the acquisition.
A beachfront residence within the gated enclave of Bella Vista on the San José del Cabo corridor, with direct access to a secluded Sea of Cortez beach and ocean views from each of its four bedrooms. A different expression of luxury, defined by the coastline itself and the character of San José, beyond the private-club environment.
Valentino represented the buyer in the acquisition.
Valentino listened to what was most important to us in a home and found the perfect community for us to settle in. Whenever we have questions about Cabo, Valentino is our first call.
For international clients, acquiring real estate in Mexico involves considerations well beyond the residence itself.
Valentino’s role frequently extends into the broader acquisition process, helping clients understand local market practice and coordinating, when appropriate, with the legal, fiduciary, tax, inspection, architectural and financing specialists involved. VanSirius does not replace those specialists. The advisory role is to keep the components of a significant acquisition aligned around the client, especially when the buyer is managing the transaction from another country or considering a highly specialized private community.
Transaction values tell only part of the story. An oceanfront homesite presents different questions from a completed estate; a second home from a family’s long-term residence. After more than two decades in Los Cabos, Valentino’s role is to bring context to those decisions. Not simply “Is this a beautiful property?” but:
Outside of real estate, Valentino spends much of his free time on the golf courses of Los Cabos — another way of experiencing the communities, landscapes and lifestyle that define the region.
For clients who share the same interest, the conversation does not always have to begin in an office or at a property showing.
If golf is part of your Los Cabos lifestyle, reach out. Valentino may even be able to help arrange a round at one of the region’s private or members-only courses, depending on access and availability.
Sometimes the best conversations happen on the course.
Play a Round. Talk Business. →Valentino’s advisory work is supported by continuous analysis of the Los Cabos luxury market.
Through VanSirius market reports and editorial notes on the region’s communities, he follows inventory, pricing behavior, new development, private-club communities and resale activity throughout Los Cabos. The objective is not prediction for its own sake. It is better decision-making: clients should understand not only the property in front of them, but the market surrounding it.
Valentino is a professional with invaluable ethics, an eye for shenanigans, and committed attention to detail — and continues to go far beyond expectations, years after the deal.
Speak directly with Valentino about a luxury or ultra-luxury acquisition or sale in Los Cabos, or request an informed second opinion before a significant decision. Every conversation is private, from the first discussion through the transaction and beyond.
