Central is where Singapore's three housing types sit closest together.
HDB flats in Toa Payoh and Queenstown resell to upgraders and families, condos in Districts 9, 10 and 11 attract investors and expatriates, and landed homes around Bukit Timah sell slowly to a small pool, with restrictions on who may buy.
Sellers do their homework. CEA's public register lets anyone look up an agent's registration and transaction record, and its advertising guidelines expect claims of expertise or success to be backed by verifiable records. Commission is negotiable, with no fixed rates.
Buyers and sellers browse PropertyGuru and 99.co, but the choice of who lists the home is made on an agent's own page and profile.
