Meta ads in an HDB town are about frequency and relevance. Bukit Panjang households live in dense blocks, so an audience for a single estate can be tested at small scale.
The risk is a mismatch rather than cost: a Zhenghua household is unlikely to want a crew that starts at Bukit Panjang Central.
Many residents commute to other parts of Singapore on the Downtown Line, so ads are seen anywhere, but the offer has to be local. Property offers face PropertyGuru and 99.co, so the ad promises an appraisal or a management review, not a listing.
Trades need proof, so the ads show real work and state the licence line: CEA for agents, and NEA, BCA or PUB where relevant. Budgets and fees are in S$, with GST at 9% stated.
HeyLead is the marketing team, not the licence holder.
