Valuing a 150 m², 5-bed detached home in Singapore at S$1,776,000

I’m torn between valuing this Singapore detached home from the one completed comparable and treating that sale as too thin a basis on its own. The light and location are appealing, but the dated finishes and wider ownership costs may be getting less attention than they deserve.

The home has five bedrooms, is stated as about 150 m² and is offered at S$1,776,000. Three nearby properties provide asking-price context, yet only one actual sale looks potentially comparable. I still need to confirm whether 150 m² means internal area or land area, as well as tenure, micro-location, parking, outdoor space and any shared or service charges.

Would you start with the completed sale and adjust item by item, or set a broad range until those facts are known? I’m trying to separate likely market value from the maximum price that still leaves room for maintenance, insurance, tax and updating.
 
Use the completed sale as the anchor and treat the three asking prices as context, not equal evidence. For condition, I would estimate the near-term work item by item rather than apply a generic percentage. Floor-area adjustments should come from genuinely similar homes; they are rarely linear.
 
One thing I missed: does the 150 m² describe internal floor area or the land parcel? For a detached home, that distinction could change the entire comparison. I would not calculate an adjustment until both figures are known.
 
Exact tenure and remaining lease length would be my biggest missing fact, followed closely by land area. The completed comparable is only persuasive if its tenure and micro-location are similar. Two homes in the same broad area can still differ because of their particular street position.
 
I also disagree with treating every extra square metre as equally valuable. A useful living area, awkward circulation space and an extra cramped bedroom do not contribute in the same way. With five bedrooms inside roughly 150 m², the actual layout deserves close attention.
 
Parking and private outdoor space could explain part of the gap before condition does. Compare the number and practicality of parking spaces, access, garden or terrace usability, and privacy. Those features need to match reasonably well across the four properties.
 
Build a simple comparison table with sale or asking status, date, tenure, floor area, land area, bedroom count, condition, parking, outdoor space and precise location. Leave blanks visible. It will quickly show whether you have one real comparable or four properties that merely look similar in listings.
 
Property tax, insurance and maintenance belong in the ownership budget, but I would not automatically subtract their projected totals from market value. Buyers may react to recurring burdens, yet the relationship is not necessarily dollar for dollar. Verify the Singapore-specific tax position separately.
 
On the stated floor area, the asking price works out to S$11,840 per m². That is useful arithmetic but potentially a misleading valuation metric if the comparable prices reflect different land areas, leases or outdoor space.
 
For condition, separate cosmetic datedness from deferred maintenance. Old colours and finishes are one category; ageing building elements or unresolved defects are another. Obtain estimates for work you would actually undertake, then test the valuation both with and without optional cosmetic upgrades.
 
The maintenance concern is too vague at present. What appears dated during a viewing may be serviceable, while less visible items may matter more. An inspection and realistic maintenance plan would tell you whether this is mostly taste or a genuine near-term cash requirement.
 
I partly disagree with Diego on recurring costs. They should not be deducted mechanically, but unusually high unavoidable costs can affect what a buyer will pay. The key is establishing whether these expenses are actually unusual relative to the completed comparable.
 
How recent and how close is the completed sale? Also, was it in comparable condition at the time of sale? If either answer is weak, I would avoid giving that one transaction too much authority despite it being better evidence than asking prices.
 
Do not average the three asking prices. Sellers can ask aspirational amounts, and each listing may require different adjustments. Their useful role is showing the current alternatives a buyer could consider, not proving that those amounts are achievable.
 
Agreed with Laura. If those asking-price homes remain available, that may itself suggest buyers have not accepted the prices yet, although the listing timeline is needed before drawing conclusions. Their current status and any price changes would add context.
 
If financing matters, model the consequence of a formal valuation below S$1,776,000 before negotiating. The practical risk is not only overpaying; it is also having to contribute more cash or reconsider the purchase if the lender's figure differs.
 
Because light and location are the strongest features, visit the street at different times and identify exactly what creates that premium: orientation, outlook, noise, access, privacy or parking convenience. “Good location” is too broad to adjust against another property reliably.
 
I would produce low, central and high cases rather than one adjustment range. Start from the completed sale, insert refurbishment estimates for condition, and leave floor-area value as a sensitivity until a close size match appears. That makes the uncertainty visible instead of hiding it in one percentage.
 
Confirm how the 150 m² was measured and which spaces it includes. If one listing counts areas differently from another, a per-square-metre comparison becomes false precision. The formal appraiser can also explain which area basis is appropriate locally.
 
Service charges were mentioned as a possible angle, but are there actually any shared-estate or common-area charges here? A detached home should not simply be assumed to have none or to have them. Establish the arrangement and compare like with like.
