About Diana

Nearly Two Decades of Quiet Influence

Diana Tran has spent close to twenty years building the kind of relationships that simply cannot be rushed. Operating at the intersection of London's most exclusive private networks, she connects discerning investors and families with properties — and opportunities — that never reach the open market.

Founded in London and now operating globally, DTL London partners with high-net-worth and ultra-high-net-worth clients to access, structure, and optimise international real estate investments with the same discreet, personalised approach that has defined Diana's career.

What We Do

A Full-Service
Investment Partnership

From the first conversation to completed transaction and beyond, DTL London manages every dimension of your real estate journey. We don't just find properties — we structure investments, curate lifestyle, and protect your interests at every stage.

Prime & Super-Prime Acquisitions

From Mayfair pied-à-terres to trophy mansions in Belgravia and Knightsbridge — we secure London's most exclusive addresses, many before they ever reach the market.

Large-Scale Investment & Development

Representing UHNW investors in the acquisition of residential buildings, development sites, and portfolio-level opportunities across London and key international markets.

Off-Market Access

Our most valued service — a trusted network cultivated over two decades gives clients exclusive access to properties that will never appear on Rightmove or any public portal.

Relocation & Lifestyle Curation

More than property — we assist with schools, lifestyle setup, personal security, interior design partnerships, and the full logistics of high-end relocation to London and beyond.

Transaction Advisory

An extensive network of legal, tax, and financial specialists — carefully selected for their discretion and expertise — facilitates every dimension of your transaction, however complex.

Portfolio Strategy & Optimisation

For investors building or refining an international real estate portfolio — we provide strategic guidance on market timing, asset selection, and long-term value positioning.

How We Work

The DTL Process

Step 01

Discovery Conversation

We begin with a private conversation to understand your objectives, timeline, lifestyle requirements, and investment thesis. No obligation, complete discretion.

Step 02

Curated Search & Access

We activate our network — including off-market sources unavailable to other agents — and present only the properties that genuinely align with your criteria.

Step 03

Negotiation & Structuring

Diana personally leads every negotiation, leveraging two decades of relationships to secure the best terms. Our advisory network handles legal, tax, and financing complexity.

Step 04

Completion & Beyond

Our relationship doesn't end at exchange. From interior design introductions to property management and portfolio review, we remain your trusted advisor for life.

Client Voices

Trusted by Those Who
Demand Discretion

Diana's access to off-market stock in Mayfair is genuinely unrivalled. She found us a property that simply didn't exist publicly — and negotiated a price that surprised even our advisors.

Private Family Office — London

What sets Diana apart is the personal attention. She is the only person we trust to represent our interests in the London market. Truly a rare calibre of advisor.

UHNW Client — Middle East

From the first call to handing over the keys — every detail was managed with an elegance and precision that matched the property itself. We wouldn't use anyone else.

Technology Entrepreneur — Asia Pacific

Diana structured a complex cross-border acquisition that three other agencies told us was impossible. Her network, her tenacity, and her discretion are unmatched.
