My story

Why I invest with data

When I was 13, bad property advice bankrupted my family. Years later I found the numbers that told the whole story — and they changed how I see every property decision since.

−14.4%

Parents' HDB (Teck Ghee Evergreen), 2007–2020

+98.6%

The Gardens at Bishan, 2009–2023

Same years. Same neighbourhood. The difference wasn't luck — it was the data nobody showed my parents.

“Why CCR Properties Are Underperforming in 2026”

The one test only ~10% of new projects pass — and why those are the ones that hand out the largest six-figure gains.

The Overpay Filter

A simple cost and market analysis that shows whether you're overpaying for a unit before you commit.

The Launch-Switch Framework

How the price gap between brand-new launches and nearby resales reveals hidden equity — whichever side you buy.

Work with me

Ready to plan
your next move?

I work with a small number of clients who are serious about structuring their property wealth — whether that's the next purchase or a full portfolio restructure for retirement.

Who I work best with

  • Investors moving from a single HDB/condo into multiple asset classes.
  • Families planning multi-generational wealth and retirement via rental income.
  • Business owners seeking commercial assets with >5% yield and tax efficiency.
  • First-time investors starting their property journey properly.
  • BTO upgraders who want the upgrade to also be a sound investment.
