Is This D9 3‑Bed Undersized—or Underrated? River Modern Type C1 in Numbers
River Modern is a District 9, 99‑year leasehold new launch by GuocoLand with 455 residential units (and 6 commercial shops on Level 1), targeted for Vacant Possession (VP) in 2H 2030.
This post focuses on 3 Bedroom Type C1, officially 74 sqm / 797 sqft (harmonised), with 3 bedrooms and 2 bathrooms (master ensuite + common bath), and positioned in the “standard 3BR” category of the project’s unit mix.
Because River Modern is a harmonised project, direct size comparisons with older developments can be skewed. URA/SLA/BCA/SCDF introduced harmonised floor area definitions effective 1 June 2023 (e.g., aligned measurement conventions such as measuring to the middle of walls, and excluding voids from strata).
For best‑fit comparability with older condos, we apply the Type C1 adjustment: add ~70.68 sqft of estimated “non‑strata” area to benchmark it at ~868 sqft on a non‑harmonised equivalent basis.
Using Propnex’s latest ProTrend 3‑bedroom rental $psf graph (generated on 27 Feb 2026), the 2025 rental landscape for surrounding projects ranges from ~$6.10 to ~$8.37 psf/month. When translated to a like‑for‑like 868 sqft basis, that implies monthly rents of about ~S$5,295 to ~S$7,265 for comparable family‑sized units.
Projecting forward to 2030, with three scenarios (and explicitly stated assumptions), River Modern Type C1 plausibly stabilises at ~S$7.9k to ~S$9.3k/month on the 868 sqft benchmark basis (or ~S$7.3k to ~S$8.5k/month if the market anchors rent to the official 797 sqft). Using an indicative purchase price anchor of S$2,298,000 for a 3‑bed/2‑bath/797 sqft River Modern listing, that maps to roughly ~4.1% to ~4.9% gross yield on the 868 sqft benchmark (or ~3.8% to ~4.5% on the 797 sqft basis).
This is scenario analysis, not advice. Real outcomes will hinge on lease‑up timing, competing new supply (notably River Green, VP June 2030, 524 units, also in D9), and financing/carry costs during the pre‑completion period.
What you’re buying: Type C1 layout, size, and why we benchmark at 868 sqft
River Modern’s 3-bedroom units start from 797 sqft (harmonised), with indicative prices from S$2,298,000 for this configuration.
Type C1 is identified in the floor plan list as a 3‑bedroom unit of 74 sqm / 797 sqft, with a balcony, a master bedroom with an ensuite, bedrooms 2 and 3, and a common bathroom (i.e., 2 baths total).
River Modern is also positioned as directly linked to Great World MRT Station (Thomson–East Coast Line), and Great World MRT has been operational since TEL Stage 3 opened for passenger service on 13 Nov 2022—a connectivity factor that tends to support tenant demand for central rentals once the project is completed.
Harmonisation, interpreted practically
The harmonisation circular introduced a unified approach across agencies and took effect on 1 June 2023. It highlights key changes, such as measuring floor areas to the middle of the wall and excluding voids from strata area—changes that can shift the marketed “headline sqft” compared to older projects.
Because of this, comparing a 2020s harmonised unit to a pre‑harmonisation unit can understate the newer home’s lived/functional footprint if you only compare the official strata figure. That’s why our best‑fit approach will be helpful: for benchmarking with older developments, treat Type C1 as:
- Official published (harmonised): 797 sqft
- Best‑fit benchmark for comparables: 797 + 70.68 ≈ 868 sqft (our estimated adjustment)
In the sections below, we use 868 sqft to convert surrounding condos’ rent $psf into “apples‑to‑apples” implied rents, while also showing sensitivity using 797 sqft (because some leasing conversations may still anchor on the official stated size).
Competitive set: surrounding 3BR benchmarks and the size reality check
River Modern’s 3BR Type C1 is by far the smallest 3‑bedroom in the comparison set, and the closest mainstream 3BR sizing among these is Martin Modern. Here’s how the 3-bedroom unit sizes compare across the surrounding developments:
- River Modern Type C1: 797 sqft
- Martin Modern smallest 3BR types: 1,012 sqft (3BR Type C1/C2 variants)
- The Avenir 3BR Type (3)a: 1,141 sqft
- Riviere 3BR types include 1,141 sqft, 1,173 sqft, 1,249 sqft (plus larger “premium” stacks)
- Martin Place Residences 3BR Type C1: 1,421 sqft
- Rivergate 3BR examples: ~1,507 to 1,711 sqft (and larger variants exist)
Here’s a structured “fit for purpose” comparison table:
| Project (benchmark) | Tenure | District | Completion info | Typical 3BR size (published) | Relevance when comparing to River Modern’s C1 (797 harmonised; ~868 benchmark) |
| Martin Place Residences | Freehold | D09 | VP 2011 | 3BR 1,421 sqft (C1); 3BR+Study 1,722 sqft | Prime D9 address but far larger 3BRs; good “location prestige” reference, weaker on rent quantum comparability. |
| Riviere | 99‑year | D03 | VP Q4 2022 | 3BR 1,141–1,249 sqft mainstream; larger premium types | Strong modern river‑adjacent reference; still much larger than River Modern’s C1. |
| The Avenir | Freehold | D09 | VP 1 Aug 2025 | 3BR starts at 106 sqm (~1,141 sqft); larger private‑lift variants exist | High‑quality “new freehold D9” rent benchmark; size makes the absolute rent higher than River Modern’s C1. |
| Martin Modern | 99‑year | D09V | VP 31 Dec 2021 | Smallest 3BR 1,012 sqft | Closest size/position proxy in the set; still ~27% larger than RM C1 (1,012 vs 797). |
| Rivergate | Freehold | D09 | VP 2009 | 3BR often ~1,507–1,711 sqft in shown plans | Lifestyle/river‑proximity proxy but much older and much larger; rent quantum not directly comparable. |
The key analytical implication: for a compact 3BR like RM C1, $psf rent comparisons are more diagnostic than absolute rents, but tenant budget psychology still matters (families often shop by monthly rent quantum first).
What the latest ProTrend 3BR rental graph says today
Below is the ProTrend chart (generated 27 Feb 2026) showing yearly rental trends from 2015–2026 for the surrounding projects.
From the visible 2025 labels on the chart, the 2025 rent $psf/month baselines are approximately:
- Martin Modern: $8.37 psf
- The Avenir: $8.03 psf
- Riviere: $7.89 psf
- Rivergate: $6.39 psf
- Martin Place Residences: $6.10 psf
This naturally splits into two groupings:
The higher band (newer/prime‑positioned modern condos): ~$7.9–$8.4 psf (Martin Modern, The Avenir, Riviere).
The lower band (older/larger‑format stock): ~$6.1–$6.4 psf (Rivergate, Martin Place Residences).
Translating 2025 rent $psf into implied monthly rents using 868 sqft
Using our adjusted 868 sqft comparison benchmark (797 sqft + 70.68 sqft), the implied 2025 monthly rental estimates are as follows:
| Comparable (2025 baseline) | 2025 rent $psf (from ProTrend) | Implied monthly rent @868 sqft |
| Martin Modern | 8.37 | ~S$7,265 |
| The Avenir | 8.03 | ~S$6,970 |
| Riviere | 7.89 | ~S$6,849 |
| Rivergate | 6.39 | ~S$5,547 |
| Martin Place Residences | 6.10 | ~S$5,295 |
A practical “translation” for River Modern Type C1: a compact 3BR in this micro‑market that can justify rent psf in the ~$7.9–$8.4 band would typically clear high‑S$6k to low‑S$7k monthly on an 868 sqft benchmark, and ~8% lower if a tenant/agent insists on using 797 sqft as the rentable‑size anchor.
Projecting River Modern Type C1 rents and gross yields in 2030
Why a scenario approach is the cleanest method here
River Modern is expected to deliver around 2030 (VP 2H 2030; listings may state TOP Jan 2030). That means any forward rent estimate must bridge multiple uncertainties (macro rental cycle, supply pipeline, and tenant demand).
For transparency, we’ll use a scenario framework grounded in two principled choices:
- Use the ProTrend 2025 “modern prime” 3BR band (Martin Modern, The Avenir, Riviere) as the starting anchor for what this neighbourhood clears in rent $psf today.
- Use official methodology context: Singapore’s private residential rental index is computed from IRAS tenancy information, and (from 1Q2015) uses a stratified hedonic regression to control for attribute differences like age and unit size, which is consistent with thinking in $psf and adjusting for size comparability.
Assumptions used for projection
Anchor rent psf:
– Take the average of 2025 rent psf for Martin Modern (8.37), The Avenir (8.03), Riviere (7.89) ≈ ~8.10 psf as a “prime modern 3BR” neighbourhood anchor (from the ProTrend chart).
Newness premium at/near completion:
– River Modern will be brand new at 2030 handover; we apply a modest “newness + fresh‑facility” premium, recognising that other comps will also still be relatively modern but older by 5–9 years (e.g., 2021–2025 completions). River Modern’s direct‑MRT positioning is part of its value proposition.
Growth rates (2025→2030 CAGR):
– Conservative: 2.0%
– Base: 3.0%
– Optimistic: 4.5%
Newness premium applied on top of market growth:
– Conservative: +2%
– Base: +4%
– Optimistic: +6%
2030 rent and yield outputs using a S$2,298,000 price anchor
For yield, we need a price reference. We will use the S$2,298,000 “starting from” price for a 3‑bedroom, 2‑bathroom, 797 sqft unit, with VP in 2030 and a 99‑year lease stated.
We compute: Gross Yield = (Monthly Rent x 12)/$2,290,000
and present both the 868 sqft benchmark (for comparability) and the 797 sqft sensitivity (if the market anchors on the official size).
| Scenario | CAGR (2025→2030) | Newness premium | Projected 2030 rent $psf | 2030 rent @868 sqft | Gross yield @868 sqft | Sensitivity: 2030 rent @797 sqft | Sensitivity: gross yield @797 sqft |
| Conservative | 2.0% | 2% | ~9.12 | ~S$7,918/mo | ~4.13% | ~S$7,270/mo | ~3.80% |
| Base | 3.0% | 4% | ~9.77 | ~S$8,477/mo | ~4.43% | ~S$7,783/mo | ~4.06% |
| Optimistic | 4.5% | 6% | ~10.70 | ~S$9,287/mo | ~4.85% | ~S$8,528/mo | ~4.45% |
Two important interpretations:
First, River Modern C1, being the smallest 3BR in the set, can be a double‑edged sword: it may achieve competitive $psf rent (small family units often rent “efficiently” on psf), but its absolute monthly rent will typically sit below the big 1,4xx–1,7xx sqft 3BRs that dominate older prime stock.
Second, the sensitivity column matters: if leasing norms “price rent” off the official 797 sqft, your monthly rent (and yield) is roughly ~8% lower than the 868 sqft benchmark math.
Key risks and competing supply into 2030
A few risks deserve explicit attention (because they can swing lease‑up results far more than a decimal point of CAGR):
Competing new supply in the same MRT catchment: River Green is another major development in the same District 9 River Valley/Great World catchment, listed with 524 units and Vacant Possession in June 2030. That is nearly the same completion window as River Modern and could compete for the same tenant pool in the first 6–18 months of lease‑up.
Lease‑up and tenant profile fit: Type C1 is a compact 3BR. The tenant pool may skew to households who want a third room but are willing to accept a more compact living/dining footprint. This can be great in a tight market, but in a soft market, it can increase negotiating pressure from tenants compared to larger “legacy 3BRs” nearby.
Financing and holding‑period sensitivity: A 2030 delivery means you are exposed to multi‑year interest rate and household income variability before rental income begins (if investing) or before you can move in (if owner‑occupying). The “carry” risk is often the practical limiter, not the headline gross yield.
Data/volume caveat on micro‑series: The ProTrend chart is directionally helpful, but year‑to‑year volatility can be influenced by transacted rental mix and smaller sample sizes, especially for specific bedroom segments in specific projects.
Practical takeaways for homeowners and investors
For homeowners considering Type C1: River Modern’s positioning (direct Great World MRT connectivity; D9 river‑adjacent living) supports a lifestyle proposition that remains strong even if market rents soften.
The key personal question is whether the compact 3BR format fits your “real life” needs for living/dining comfort, storage, and work/study use.
For investors: Type C1 is fundamentally a “compact family 3BR” bet, where your edge is often a lower rental quantum than the huge legacy 3BRs nearby, while keeping prime‑core accessibility. The scenario analysis suggests a plausible 2030 gross yield band of roughly ~4%–5%, but those are gross figures and do not include vacancy, agent fees, maintenance, furnishing, or property tax.
A practical approach (not advice) is to plan two leasing strategies now: a “fast‑lease” rent to reduce vacancy risk during initial lease‑up, and a “premium‑positioning” rent if the 2030 market is tight—especially considering competing completions like River Green.
