Singapore Property Advisory · Founder of PropertyInsider.sg
I'm Jamus Lee, a licensed advisor with ERA Realty Network and the founder of PropertyInsider.sg. I help upgraders, buyers and investors work out what a move actually costs — across condominiums and landed homes — before anyone talks about signing anything.
Ask five people whether you should upgrade and you'll get five answers. Your colleague says buy now. Your relative says wait. The news says both, in the same week. None of them have seen your CPF balance, your loan headroom, or what your flat would actually fetch.
That's the gap I work in. Before we discuss a single project, we put your real figures on the table — what you'd walk away with after selling, what you can borrow, what the stamp duty costs, what the monthly repayment looks like if rates go back up. Once those numbers exist, the decision usually makes itself.
And if the numbers say stay put, I'll say so. That answer costs me a commission and saves you a mistake, which is a trade I'm happy with.
Meet Jamus Lee
I came into real estate from engineering and consulting, and I never quite dropped the habit of checking things. Where a land parcel sold for. What the surrounding resale market is actually transacting at. Whether a project's price makes sense once you stack up land cost, construction and finance.
That habit turned into a second job. I founded PropertyInsider.sg to publish that research openly — launch price estimates with the cost stack shown, land tender results, and matched resale outcomes. It keeps me honest, because anything I tell a client in private is already published where anyone can check it.
What clients get from that is simple. Advice that starts with your situation, not with whatever project I'm marketing this month.
Founder & CEO
PropertyInsider.sg is the Singapore new-launch research platform I founded and run. It tracks every launch and Government Land Sales site, estimates launch prices from the land cost up, and maps what resale buyers have actually made — and lost — on each project.
Every figure carries its source and its date. Estimates are labelled as estimates. That standard is the reason I can sit across from a client and show my work rather than ask them to take my word for it.
The Research Library
Everything I publish sits under one of five hubs. Work through them in order if you're starting from scratch, or jump straight to the one that matches your question.
Before any project makes sense, you need to know what you can move with.
Once your budget is real, these three narrow the shortlist.
From the Research Desk

13,480 flats reach the end of their five-year minimum stay this year, against roughly 3,620 new homes launching. The same households usually sit on both sides of that squeeze.

Rates near 1.12%, land tenders averaging 5.3 bids a site, and a $1,820 psf ppr record. Five slow forces move prices; headlines move mood. Here's how to tell them apart.

The life-stage companion piece: which of the three moves fits a first-timer, an upgrader and an investor in this market, and what each one gives up.

Land rates up nearly 39% in a year, and the May 2026 EC rewrite — a ten-year stay on land sold from 8 May, no deferred payment, 90% to first-timers. What it changes for upgraders.

How I Evaluate a Launch
Showflats are built to make you feel something. A framework is what stops the feeling from doing the deciding. Every project I review goes through the same five checks, in the same order, whether I'm marketing it or not.
Location fundamentals. What's funded and dated, not merely drawn on a master plan.
Developer track record. How their past projects have held up on resale.
Unit mix. Which stacks and layouts the market will still want in ten years.
Price against comparables. Land cost, construction, finance — does the asking price stack up.
Exit. Who buys this from you, and at what price.
How I Can Help
Client Testimonials
Jamus walked us through his detailed marketing plan, explaining thoroughly how he'd position our unit. We secured multiple offers within the second week and sold our flat above our initial expectations.
Jamus is more than just an agent — a trusted advisor with immense passion and integrity. He helped us buy our resale condo years ago and has consistently looked after our interests, operating with fairness and transparency.
Jamus provides top-notch service with incredibly speedy responses. He truly prioritises his clients, always available to answer queries and offer advice.
Jamus hires a professional photographer and has an effective marketing strategy. We had 4–5 viewings during the very first weekend our property was listed, leading to a swift and successful sale.
I met up with Jamus to go through financial calculations. He makes sure I'm comfortable with the numbers, and is not a typical salesy or pushy agent.
We needed to sell ASAP, and were fortunate to have Jamus. Our property was sold in less than two weeks.
