What is CheckHowMuch.sg?

CheckHowMuch.sg is a free property data platform that shows HDB resale prices, valuations, and lease decay projections for 9,694 blocks across 26 towns in Singapore. All data is sourced from data.gov.sg. No login or personal information required.

Why was CheckHowMuch created?

CheckHowMuch was created because publicly available HDB data from data.gov.sg was being gate-kept by property portals that require phone numbers or emails to access. CheckHowMuch makes this public data freely accessible with no login, no forms, and no lead generation tactics.

Is CheckHowMuch free?

Yes. CheckHowMuch is completely free. No login, no registration, no phone number, no email required. All HDB resale price data, valuations, and lease decay projections are accessible without any gated content.

About CheckHowMuch

Public data should be
publicly accessible.

No login. No phone number. No nonsense.

Why This Exists

The flyers

Every week, property agents stuff flyers into my gate. "Your neighbour just sold for $X!" I'm not selling my house. They go straight into the bin. Every single time. Such a waste.

The data gatekeeping

HDB publishes all resale transaction data on data.gov.sg. It's public. It's free. It's paid for by taxpayers. But to actually see this data in a usable format, you have to hand over your phone number or email to a property portal. Then the calls start. Then the emails start.

These portals take free public data, wrap it behind a lead capture form, and use YOUR information to sell you services you didn't ask for. The data was always yours. They just made you pay for it with your privacy.

So I built CheckHowMuch. Public data, publicly accessible. No login. No forms. No lead gen. Just the information you came for.

Why "CheckHowMuch"

Made in Singapore, by a Singaporean, for Singaporeans. I wanted a name that felt local. Something your auntie would say. Something you'd type into Google exactly as you'd say it out loud.

"Eh, how much ah?"

"Go check how much lah."

So that's what we called it.

Who Built This

Keith Teo

Founder, CheckHowMuch

Based in Singapore. I build tools that make public data accessible to everyone and run workshops teaching people how to build with AI. I believe that if taxpayers paid for the data, they should be able to use it without handing over their phone number.

CheckHowMuch started from genuine frustration. I'm an HDB homeowner who got tired of property portals gate-keeping public information behind lead capture forms. So I built the tool I wished existed: every block, every transaction, no login required.

No investors. No ads. No sponsors.
Just a homeowner who got tired of throwing away flyers.
