Rooted in Singapore,
guided by care
Nonya Keys was founded on the belief that finding a home in Singapore's most characterful districts should feel personal — not transactional.
Back to HomeA name drawn from
Singapore's living heritage
The Nonya tradition — rich with craft, colour, and an enduring sense of home — gave us our name. We carry those values into every residential engagement. Nonya Keys was established in Singapore with a clear purpose: to help individuals and families find, secure, and settle into homes that suit them properly.
Our founders recognised that the city's most sought-after residential enclaves — the heritage terraces of Emerald Hill, the quiet lanes of Katong, the garden edge of Dempsey — were best understood by those who had walked them many times over. Property knowledge accumulated over years, not weeks.
Today, Nonya Keys serves a growing community of residents who appreciate that a home is not simply a transaction. It is a place where daily life unfolds. We take that seriously in everything we do.
What guides us
Three principles shape every engagement we take on.
Warmth
Finding a home is an intimate process. We approach it with patience, attentiveness, and genuine care for the people we serve — not just the properties they consider.
Discernment
We look beyond square footage and rental figures. Our advisors assess character, light, neighbourhood rhythm, and livability — the qualities that make a house feel like a home.
Integrity
We represent our clients' interests clearly and honestly. Our advice reflects what we genuinely believe is right for you — informed by data and experience, free from external pressure.

How we work
Every engagement follows a considered process built on professional standards and personal accountability.
CEA Registration
All client-facing advisors hold active registration with Singapore's Council for Estate Agencies — the professional standard for residential property services in Singapore.
Client Confidentiality
We handle all client information with strict discretion. Personal data shared during any engagement is protected in line with Singapore's Personal Data Protection Act.
Transparent Documentation
Every service engagement is confirmed in writing. Clients always know what is included, what the fee covers, and how to reach us throughout the process.
Ongoing Professional Development
Our team regularly participates in industry seminars, rental market briefings, and heritage conservation updates to remain well-informed advisors for our clients.
Impartial Advice
We do not take referral fees from landlords or property managers. Our advice is shaped entirely by what is best for the client — without influence from other parties.
Post-Engagement Review
We follow up with clients after each engagement to understand what worked well and where we can do better — a practice we treat as an integral part of our service quality.
Residential leasing expertise rooted in Singapore's heritage districts
Nonya Keys operates at the intersection of property knowledge and personal service — two qualities rarely found together in Singapore's fast-moving rental market. Our focus on conservation terraces, landed homes, and characterful apartments in Emerald Hill, Joo Chiat, Katong, Dempsey, and Tanglin reflects a deliberate commitment to the kinds of homes that reward careful selection.
Clients who come to us are typically seeking more than a listing search. They want informed perspective on neighbourhoods — the morning noise, the walk to school, the proximity to markets, the feel of the street on a rainy afternoon. These are the qualities our advisors discuss openly and honestly during every Heritage District Tour.
Our Lease Structuring service addresses a gap many renters encounter: the lease document arrives, and it is expected to be signed quickly. Nonya Keys ensures our clients read every clause with full understanding — and that any terms worth amending are raised professionally and promptly. The result is a tenancy entered into with clarity on both sides.
Private Estate Stewardship reflects the needs of residents who value continuity and a trusted point of contact for all household matters. Whether coordinating a seasonal deep clean, managing an appliance repair, or facilitating a housekeeper arrangement, our stewards handle logistics so that home life flows smoothly.
