How would you adjust the only sold comparable for this Singapore duplex?

[beam.fresh]

I can value this from the single recorded transaction, despite the risk that it is a poor match, or lean on three current listings that show only what sellers hope to receive. Neither route makes the S$850,900 asking price easy to defend.

The property is a 2-bed Singapore duplex described as roughly 250 m² and in average condition. Its light and micro-location appeal to me, but the finishes are dated and the recurring costs remain unclear. Before adjusting for condition, I need to establish whether the stated area includes stairs, voids or outdoor space.

Which facts would you verify first from the sale and property records: remaining lease, service charges, parking, area breakdown or private outdoor space? Once those match, I could test a modest condition adjustment rather than applying one to the entire 250 m² without knowing what that figure represents.

Before you put weight on that one sale, I would challenge the assumption that floor area should be the first adjustment. It is tempting because 250 m² looks precise, but lease length, exact micro-location and recurring service charges may create the larger and less reversible difference.

Use the three active listings only as context for current competition. For the completed transaction, first obtain its tenure, bedroom count and area breakdown. For example, 20 m² of terrace or void should not automatically be compared with 20 m² of enclosed living space. Once those points line up, a 5–10% sensitivity for dated but usable finishes could be informative, with a larger allowance only where substantial work is evident.

The 250 m² needs unpacking. Is that all enclosed, usable floor area, or does it include outdoor space, voids, stairs or other less valuable area? A large 2-bed layout may not command the same rate per square metre across every part of the property. I’d also want the completed comparable’s area and bedroom count before choosing any floor-area adjustment.

I wouldn’t start with condition. The fact most likely to change the valuation is remaining lease length, followed closely by exact micro-location and building-specific charges. Two superficially similar Singapore properties can become poor comparables if those differ materially. Dated finishes are visible and negotiable; tenure and recurring costs affect the whole ownership proposition.

Aya, agreed on tenure, but I’d still avoid one percentage adjustment for the entire floor-area difference. Extra area often has a lower marginal value, particularly if it is circulation space or outdoor area rather than another useful room. I’d split the property into usable internal space and secondary space, then compare each component with the sale as far as the available details allow.

Parking could also distort the single completed comparable. If one property has an allocated space and the other does not, the headline prices are not directly comparable. Same for private outdoor space. I’d build a simple table with sale date, micro-location, remaining lease, measured area basis, condition, parking, outdoor space and service charges. Blank cells will show where the apparent precision is false.

 

[StillWay]

A caveat on the suggested 5–10% condition test: that may be useful for modelling, but it should not become an automatic deduction. Cosmetic dating and deferred maintenance are different things. Obtain an itemised view of what actually needs replacing, then consider whether buyers would discount by the cost, the disruption, or neither. Insurance and maintenance history may reveal more than the finishes.

Before debating fine adjustments, verify the basic arithmetic and listing particulars. S$850,900 over 250 m² is about S$3,404 per m², so either it is a compelling price or one of the inputs needs context. Confirm currency, tenure, property classification, area definition and whether the asking figure includes everything you think it does. One incorrect field would overwhelm any careful condition adjustment.

 

[StillWay]

That arithmetic is exactly why the completed sale should be reconstructed rather than merely converted to a per-m² figure. My next steps would be: confirm the 250 m² basis, obtain the lease details and recurring charges, identify what parking and outdoor rights transfer, and compare the two micro-locations. Only then run low, middle and high condition scenarios. If those facts cannot be verified, the valuation range should stay wide despite the three asking comparables.
