New Launch Condos Now Cost 20-30% More Than Resale. But Is the Premium Justified?
Last month a buyer asked me to compare River Modern against Martin Modern. Same developer. Same street. “River Modern is 22% more expensive leh. Is it worth it or not?”
I pulled out a spreadsheet I’ve been refining for years. 4 adjustments later, the “22% premium” shrank to about 1-3%.
That’s the thing about the “new launches cost 20-30% more” line everyone loves to throw around. You see it on PropertyGuru articles, YouTube thumbnails, agent slides. But nobody ever breaks down whether the premium is actually justified for a specific project.
A 25% premium could be a steal. Or a rip-off. Depends on the age gap, the PSF measurement, the layout, and even the quantum. Let me show you the framework.
The $50 PSF per year formula
Start here. It’s simple and surprisingly accurate.
Take the difference in TOP years between the new launch and the resale. Multiply by $50. That’s roughly how much more per square foot the new launch should cost, all else being equal.
I first used this comparing Lentor Mansion against The Panorama. Panorama TOP-ed in 2019, Lentor Mansion was targeting 2028. 9 years apart. Justified premium: $450 psf.
Panorama 2-bedders were averaging $1,883 psf, so a fair new launch price would be $2,333 psf. Lentor Mansion launched at $2,083 psf (pre-harmonized). Below formula. Good deal.
But this is just the starting point. You need 3 more adjustments.
Adjustment 1: Harmonized vs non-harmonized PSF
This one trips up almost everyone.
Since 2023, new launches use harmonized floor area. Air-con ledges, RC ledges, planter boxes, all counted in strata area now. Before 2023, those spaces were excluded. Your 1,000 sqft unit from 2018? Its “real” liveable area might be the same as a 960 sqft harmonized unit today.
The practical adjustment: add about 4% to the harmonized area to get a pre-harmonized equivalent. Or subtract 4% from older units to normalize.
When I compared Chuan Park vs Emerald of Katong for a buyer, this mattered. Chuan Park’s C2a was 1,033 sqft including a 50 sqft air-con ledge. Emerald of Katong’s C5F was 990 sqft excluding it (harmonized). Added 40 sqft to EOK, giving 1,030 sqft. Suddenly the “size difference” evaporated.
So if you’re comparing a new launch at $2,200 psf against a pre-2023 resale at $1,800 psf, you might think that’s a 22% premium. Adjust for harmonization and the new launch’s effective psf is closer to $2,112. Real gap is 17%. Not nothing, but not 22%.
Adjustment 2: Layout efficiency
Not all square feet are created equal. Some are corridors. Some are oversized air-con ledges that you will literally never stand on unless you’re repairing the aircon.
La Fiesta is the poster child. Massive AC ledges that add to strata area but do absolutely nothing for liveability. You’re paying for dead space.
Things to check:
- Long corridors (waste of space, older designs love these)
- Oversized AC/RC ledges (3% discount if excessive)
- Bay windows (3% discount, pre-2009 projects)
- Dumbbell layout vs linear (dumbbell is more efficient)
- Study/flex room vs dead storage
Apply a +/- 1-3% adjustment per factor. A well-designed new launch layout genuinely earns part of its premium. A poorly designed one (yes, some new launches have terrible layouts) doesn’t.
Adjustment 3: Location micro-factors
Even condos in the “same area” aren’t the same.
| Factor | Premium |
|---|---|
| < 5 min walk to MRT | +10% |
| < 10 min walk to MRT | +5% |
| >= 10 min walk to MRT | 0% |
This alone explains a huge chunk of “premiums” that people mistakenly attribute to new vs resale. A condo 3 minutes to the MRT vs one 12 minutes away in the same district? 10% gap right there. Nothing to do with being “new.”
Schools, highway access, facing, floor level. All matter. But MRT proximity is the single biggest micro-factor. It’s not even close.
Case study: River Modern vs Martin Modern
Let’s put the framework to work.
River Modern launched in March 2026 at an average of $3,266 psf. 91% sold on opening weekend. The obvious comparison is Martin Modern. Same developer (GuocoLand), same district (D9), same street.
The raw numbers:
| River Modern | Martin Modern | |
|---|---|---|
| TOP | 2030 | 2021 |
| Tenure | 99-year | 99-year |
| Units | 455 | 450 |
| 3BR PSF | ~$3,420 | ~$2,793 |
| Quantum (3BR) | ~$2.73M | ~$2.5M (resale avg) |
At face value, River Modern is $627 psf more expensive. That’s a 22% premium. Looks steep, right?
Step 1: TOP age adjustment. 2030 vs 2021 = 9 years. At $50/year = $450 psf premium justified. That accounts for $450 of the $627 gap. Remaining: $177 psf.
Step 2: Harmonized PSF. River Modern uses harmonized floor area. Martin Modern (TOP 2021) is pre-harmonization. Adjusting by 4% gives an effective $3,288 psf. Gap narrows to ~$495 psf, of which $450 is explained by age. Remaining: ~$45 psf. That’s 1.6%.
Step 3: Layout and design. River Modern is a 2026 design with modern efficiency. Martin Modern has solid layouts (it’s GuocoLand, they generally don’t mess this up). Call it a wash, maybe +1% for River Modern’s newer specs.
Step 4: Location. Both on the same stretch of River Valley. Both near Great World MRT. No meaningful difference.
After adjustments, River Modern’s “premium” is roughly 1-3%. The headline “22% more expensive” melts away when you do the math.
That’s why 410 out of 455 units sold on opening weekend. Buyers who ran the numbers knew it was fairly priced. Not cheap. But fair.
When the math doesn’t work
Here’s where it gets uncomfortable.
Compare River Modern against The Avenir. Also D9, also GuocoLand, but freehold. Avenir’s 3BR resale PSF is around $3,291. River Modern’s 3BR is $3,420.
A 99-year leasehold new launch that costs more than a freehold resale that’s practically brand new? The $50/year formula gives only $250 premium for 5 years (2030 vs 2025). But Avenir already trades above that. And it’s freehold.
On paper, this doesn’t make sense.
But quantum tells a different story. The Avenir 3-bedders are bigger units at higher absolute prices. Budget of $2.7M? River Modern gives you a 3BR. At The Avenir, you might need $3M+ for a comparable unit. Different target buyer entirely.
PSF comparisons only work when the quantum range overlaps.
You live in quantum, not PSF
Nobody wakes up and says “I can afford $2,400 psf.” You say “I can afford $2.5M.” Completely different starting point.
A new launch 2-bedder at 538 sqft and $3,362 psf costs $1.81M. A resale 3-bedder at 1,100 sqft and $2,400 psf costs $2.64M. The resale has a “lower PSF” but costs $830K more. Comparing their PSFs is meaningless unless you’re looking at the same bedroom count, same size range.
When I help buyers, I always start with quantum budget first, then work backwards to what that gets you in new launch vs resale. Sometimes the resale gives you an extra bedroom for the same money. Sometimes the new launch gives you a newer, smaller unit at lower monthly outlay thanks to progressive payments.
There’s no universal answer. Which is exactly why the “new launch or resale?” question is the wrong question.
What I actually tell my buyers
Run the formula. Apply the adjustments. Look at the quantum.
If the unexplained premium after all adjustments is under 5%, it’s probably fair. If it’s 10%+, you’re paying for hype, for the showflat experience, for the feeling of being “first.”
I’ve seen buyers stretch for a new launch because the showflat marble looked amazing, only to realize the resale next door was $400K cheaper with bigger rooms and an established neighbourhood. I’ve also seen buyers refuse to pay any premium at all, then watch the new launch appreciate 15% in 2 years while their “bargain” resale stayed flat.
Both mistakes come from the same place: not doing the math.
If you’re spending $2M+ and your decision is based on vibes and a showflat visit, you’re doing it wrong.
