Singapore property listings carry asking prices that can vary 10–25% above actual transacted values — and there is no standardised mechanism forcing agents to justify asking prices with data. A seller or landlord who paid peak-2022 prices or is anchoring to a neighbour's aspirational listing can set any asking price, and without transaction data, buyers and tenants have no objective reference point. The Listing Evaluator solves this: it retrieves the actual prices that units in the same building cleared at over the past 12 months and tells you — in seconds — whether the asking price is within the market range or significantly above it. This information alone can save a buyer $50,000–$150,000 in negotiation.
The most important number the evaluator returns is the PSF gap — the percentage difference between the asking PSF and the 12-month median transacted PSF for comparable units in the development. A gap of +5% is normal (sellers ask above median and negotiate down). A gap of +15–20% means the seller is pricing significantly above what the market has actually cleared, either in expectation of finding a less-informed buyer or because they are anchoring to an outdated or outlier transaction. Knowing this gap before you make an offer tells you the realistic negotiation floor, and whether it is worth negotiating at all or walking away.
For rental listings, the evaluator is equally powerful. Singapore rental asking prices are highly variable by landlord — some price at market, others ask 20–30% above what similar units rent for in the same building, relying on tenants who do not know the going rate. The gross yield that a landlord is implying at their asking rental versus what the building has historically yielded is a direct signal of whether the rent is fair. A landlord asking $5,200/month for a 2-bedroom in a building where the median rent for 2-bedrooms is $4,200 is asking for a 24% premium over market — something that is obvious in the evaluator's output but invisible to a tenant who only sees the listing and not the transaction history.
The floor-level premium component is particularly useful for evaluating units priced at a high-floor premium. A seller who claims their floor-28 unit commands a 20% PSF premium over similar low-floor units can be verified against what the floor-premium data actually shows for that development. In many cases, sellers overestimate the premium their specific floor commands relative to what the market has paid. Use the Listing Evaluator before every viewing — it takes 30 seconds and gives you a data-backed position before you enter any price negotiation. Pair it with the Floor Premium Insight for the district-level floor curve, and the Mortgage Calculator for total financing cost at the asking price.
