Does a condo re-rate after it completes?

New launches sell at a big premium (our new-launch study puts it near +38% like-for-like). The question here is what happens after keys are handed over: does that premium hold, or does the project drift back toward the pack as it ages? We track freehold-equivalent $psf (lease stripped out) relative to same-neighbourhood, same-year peers (nearby projects, not a whole district), by years since TOP.

Index 100 = a mature 11–15-year-old project in the same neighbourhood & year (nearby projects ~1.5 km). Each figure holds micro-location, transaction year and lease constant, so only age since TOP varies.
Key finding: a just-completed project (0–2 years past TOP) trades about +16% versus a mature one nearby, and that edge fades with age — roughly 26 index points lost between a fresh project and one 26+ years old. Most of the “newness” you pay for at launch is a wasting asset: it is highest at handover and erodes as the block ages.

Why it happens

Three forces pull a fresh project’s $psf down over time: physical ageing (dated finishes, rising maintenance), the arrival of newer competing launches that reset what “new” costs, and the simple fact that the first resale cohort no longer pays the developer’s launch premium. The decline is steepest in the first several years, then flattens as the project becomes ordinary resale stock.

Investor verdict

If you buy at or just after launch, budget for the newness premium to bleed off in your first hold — you need genuine location or supply-driven growth to more than offset it. If you buy mature resale, you have already skipped that decay: you are paying closer to the land-and-location value, with the depreciation someone else absorbed.

The sweet spot for many investors is a project past its newness fade but not yet old — roughly the 6–15-year band — where the launch premium is gone but maintenance and lease are still comfortable.

How to use this before you buy

Discount the launch premium in your model

If you buy new, assume a chunk of today’s $psf is a fading newness premium — your growth has to clear that hurdle first.

Prefer mature resale for value

A 6–15-year-old project in a strong location often gives you the same address at a price the depreciation has already been taken out of.

A fresh block ages faster in $psf terms when new launches keep arriving next door — see the supply tracker.

How is this worked out? — method, data & limits
Sample
73,587 resale caveats (URA 5-year window), each with a project completion year. En-bloc rows and $psf outliers removed.
Index
Each caveat’s freehold-equivalent $psf (actual $psf ÷ the lease-decay curve) is divided by the median of nearby projects (~1.5 km) in the same transaction year, then medianed within each years-since-TOP band. This holds location, market timing and lease constant, isolating age.
Limits: a cross-section, not the same units followed over time; new-sale developer pricing is excluded (resale only), so this is the resale re-rating, not the launch-to-resale drop. Age also proxies build era (see the build-rules note).
