Can a 538 sqft 2BR deliver 4%+ Yield? River Modern Type B1 Examined
River Modern is a GuocoLand new launch in District 9 on a 99‑year leasehold tenure, with 455 residential units (plus 6 commercial shops on Level 1) and an expected Vacant Possession (VP) in 2H 2030. It is also positioned as being directly linked to the Great World MRT (TEL) and the mall.
This post zooms in on the 2‑Bedroom Type B1, a compact but “prime‑core” layout that’s officially 50 sqm / 538 sqft (harmonised) and configured as a 2‑bedroom, 1‑bath unit (the bathroom is the master ensuite; there isn’t a second common bath).
Because River Modern is a post‑harmonisation project, comparing its 538 sq ft headline size directly with older developments can be misleading. URA’s harmonisation circular (effective 1 June 2023) explains why: agencies aligned definitions and measurement approaches (e.g., measuring to the middle of wall, excluding voids from strata, and aligning strata/GFA treatment).
For a more “apples‑to‑apples” rental comparison against older projects, we adopt your best‑fit assumption: add ~48 sqft (estimated AC ledge area) to interpret Type B1 as ~586 sqft non‑harmonised equivalent for benchmarking.
Using Propnex’s ProTrend rental $psf graph of nearby condos, the 2025 baseline rent $psf ranges from ~$6.47 to ~$8.64 psf/month, which translates to around ~S$3,791 to ~S$5,063/month when scaled to 586 sqft. Under a balanced set of assumptions, a reasonable 2030 base‑case for River Modern Type B1 lands around ~S$5.5k/month gross rent and ~4.3% gross yield (with a purchase price of S$1,548,000), with sensitivity down to ~3.9% if the market anchors rent on 538 sqft instead of 586 sqft.
Key watch‑outs: (1) layout constraint (1 bath) can cap tenant willingness‑to‑pay versus a 2‑bath 2BR; (2) new competing supply around 2030, notably River Green (VP June 2030, 524 units, D9); and (3) financing and carry costs during the construction/holding period.
Project snapshot and what “Type B1 (1 bath)” really means
River Modern’s published project profiles are as follows:
- Developer: GuocoLand
- Tenure / District: 99‑year leasehold, District 09
- Scale: 455 residential units + 6 commercial shops (Level 1)
- Vacant Possession: 2H 2030
- 2‑bedroom sizing band: 538 to 689 sqft (with multiple 2BR types)
The development emphasises its direct connectivity to River Modern, its prime location along the Singapore River, and its direct link to Great World MRT Station and Great World Mall.
Type B1 specs (the unit this post analyses)
The River Modern 2-Bedroom Type B1 floor plan is 50 sqm (538 sqft) and starts from S$1,548,000. This unit layout comprises two bedrooms with a single master ensuite bathroom.
Rental Implications of the 1-Bathroom Configuration
In prime central rental markets, tenant segments willing to pay higher per-square-foot rents—such as professional sharers or small families—typically prefer 2-bedroom units with 2 bathrooms.
While a 1-bathroom 2-bedroom configuration remains rentable and can perform well, it generally appeals more to couples or smaller households. In competitive scenarios—particularly when benchmarked against marginally larger 2-bedroom, 2-bathroom alternatives—it may require more competitive pricing to sustain occupancy.

Harmonisation and why we use 586 sqft for comparables
URA’s circular “Harmonisation of Floor Area Definitions by URA, SLA, BCA and SCDF” (published 1 Sep 2022, effective 1 Jun 2023) explains the policy intent: different agencies had different floor area measurement definitions, creating productivity burdens and confusing owners; agencies then aligned to a harmonised approach.
The circular highlights several key changes that affect how “size” is understood and compared across project vintages, including:
- All agencies’ floor areas measured to the middle of the wall
- All strata areas included as GFA
- All voids are excluded from the strata area
Practical implication for buyers comparing 2020s vs 2000s/2010s condos
When you put a post‑2023 harmonised 2BR next to a pre‑harmonisation 2BR, the headline sqft can understate how the newer home “lives,” especially where functional external/utility elements (like AC ledges) are treated differently in the marketed strata figure across vintages.
Hence, the adjustment provides a defensible basis for an apples-to-apples rental benchmarking exercise.
- Official (harmonised) Type B1 size: 538 sqft
- Best‑fit comparability size (your assumption): 538 + ~48 = 586 sqft (to approximate non‑harmonised equivalence for older project comparisons)
In this blog post:
- For rental comparisons, we convert the surrounding condos’ rent per psf ft to monthly rent using 586 sq ft (your requested best‑fit basis).
- For purchase price/valuation anchors, we use the 538 sq ft basis when the market listing explicitly states that floor area.

The competitive set and comparability reality check
We selected five condos that sit naturally in the same tenant/buyer consideration set (central river‑adjacent living, modern positioning, MRT access, and “newer” design language). Still, there is a crucial nuance: several are much larger 2BR formats, which inflates absolute monthly rent even if the $psf is comparable.
Here’s the structured comparison:
| Condo (benchmark) | Tenure | District | Completion info | Typical 2BR size (published) | Relevance to River Modern Type B1 (538 harmonised / ~586 best‑fit) |
| Martin Place Residences | Freehold | D09 | VP 2011 | 1044–1163 sqft | Prime D9 address but far larger 2BR; helpful for “location prestige,” less helpful for matching rental quantum. |
| Riviere | 99‑year | D03 | VP Q4 2022 | 818–840 sqft | Modern river‑adjacent product, closer design expectations, still meaningfully larger than B1. |
| The Avenir | Freehold | D09 | VP 1 Aug 2025 | 807–829 sqft | Strong “new freehold D9” benchmark; bigger 2BRs likely command higher absolute rent than B1. |
| Martin Modern | 99‑year | D09 | VP 31 Dec 2021 | 764 sqft | Possibly the closest positioning proxy (GuocoLand lineage and modern luxury cues), but still larger than B1. |
| Rivergate | Freehold | D09 | VP 2009 | 1023–1055 sqft | Strong lifestyle/location proxy near the river, but older + much larger 2BR sets a different rent quantum band. |
The takeaway: for River Modern Type B1, $psf comparisons are more diagnostic than absolute rent, because B1 is structurally a smaller, more efficiency-driven 2BR format.
From the ProTrend rent $psf graph to implied monthly rents
Below is the ProTrend report showing yearly rent $psf movements for the selected condos.

2025 baseline rent $psf inputs
Based on the graph, we adopt the following 2025 rental $psf figures from the ProTrend data:
- Martin Modern: ~$8.64
- Riviere: ~$8.12
- The Avenir: ~$7.76
- Rivergate: ~$6.91
- Martin Place Residences: ~$6.47
Implied 2025 monthly rents (scaled to 586 sqft) + a “what‑if” yield preview
To translate psf into dollars using our best‑fit size basis:
{Implied Rent (S$/month)} = ({Rent psf}) x 586 sqdt
And to preview gross yield at the 2026 price anchor (for intuition, not as a promise):
The price anchor comes from the current listing, used as a reference point.
| ProTrend comp (2025) | 2025 rent $psf | Implied monthly rent @586 sqft | Implied gross yield on S$1,548,000 |
| Martin Modern | 8.64 | ~S$5,063 | ~3.92% |
| Riviere | 8.12 | ~S$4,758 | ~3.69% |
| The Avenir | 7.76 | ~S$4,547 | ~3.53% |
| Rivergate | 6.91 | ~S$4,049 | ~3.14% |
| Martin Place Residences | 6.47 | ~S$3,791 | ~2.94% |
This frames an important intuition: if River Modern Type B1 can “clear” rents roughly in the Riviere / Avenir band, it is already in the mid‑S$4k/month rental quantum at a 586‑sqft comparability basis—before any 2030 newness effect.
Projecting River Modern Type B1 rent to 2030 and estimating gross yield
What we’re assuming (and what we are not)
Because River Modern only hands over around 2030, 2025 is used here as a current-cycle reference point (from ProTrend), not “the rent River Modern will get now.”
We treat this as a scenario exercise, where:
- Rent movement is expressed in $psf (consistent with how Singapore’s rental indices are computed using rental contracts and methods that control for attributes like age and unit size).
- “Rent” is treated as gross rent per month (per URA’s rental statistics definitions; we are not netting out service charges, vacancy, agent fees, property tax, etc.).
- No special constraints were provided for vacancy/MCST/repairs; therefore, we assume no specific constraint and flag these as key variables for any real underwriting.
Step 1: Set a 2025 “anchor” rent $psf for River Modern Type B1
Instead of picking a single comparable blindly, we anchor on the Tier‑1 newer/modern set (Martin Modern, Riviere, The Avenir) and then apply a mild B1‑specific adjustment:
- Tier‑1 2025 average psf ≈ (8.64 + 8.12 + 7.76) / 3 ≈ $8.17 psf
- Adjustment logic:
- + River Modern is newer (2030 VP) and directly linked to Great World MRT/Mall (a convenience premium)
- – Type B1 is 2BR but 1 bath, which can cap pricing versus a 2‑bath 2BR in prime rentals
For transparency and conservatism, we round the 2025-equivalent anchor slightly down to:
- Anchor (2025‑equivalent) for B1: $8.10 psf/month
Step 2: Apply three rent growth scenarios to the VP year (2030)
We model 5 years of growth (2025 → 2030). Growth rates are not predictions; they are scenario levers.
- Conservative: 0% CAGR (slow growth / subdued rental cycle)
- Base: 0% CAGR (steady prime rental growth)
- Optimistic: 5% CAGR (tight prime rentals / strong tenant demand)
Step 3: Convert 2030 psf → monthly rent and gross yield
We compute:
- Monthly rent @586 sqft (your comparability basis)
- Monthly rent @538 sqft (sensitivity case: if the rental market anchors on the harmonised number)
- Gross yield using S$1,548,000 purchase price reference
| Scenario | Assumed CAGR (2025→2030) | Projected 2030 rent $psf | 2030 rent @586 sqft | 2030 gross yield @586 sqft | Sensitivity: 2030 rent @538 sqft | Sensitivity: gross yield @538 sqft |
| Conservative | 2.0% | ~8.94 | ~S$5,241 | ~4.06% | ~S$4,811 | ~3.73% |
| Base | 3.0% | ~9.39 | ~S$5,503 | ~4.27% | ~S$5,052 | ~3.92% |
| Optimistic | 4.5% | ~10.09 | ~S$5,915 | ~4.59% | ~S$5,431 | ~4.21% |
Interpretation: across scenarios, Type B1 plausibly sits in a ~S$5.2k to ~S$5.9k monthly rent band at VP (using the 586 sqft comparability approach). On the S$1.548M price anchor, that’s roughly ~4.1% to ~4.6% gross yield, before costs and vacancy.
Risks, competing supply, and practical takeaways
Competing supply risk around 2030: River Green as a nearby benchmark
One tangible, dated supply risk is River Green, also in District 9 and likewise served by Great World MRT, with Vacant Possession in June 2030 and 524 units. That means the market could see a meaningful amount of “new / near‑new” rental stock in the same micro‑catchment around the same time River Modern is leasing up.
Product‑specific risk: the “1 bath” constraint
Type B1’s biggest underwriting variable is not location—it’s configuration.
A 2BR/1‑bath layout can work extremely well for: – Couples who don’t need a second bath – Tenants prioritising MRT convenience and prime central living over space – Price‑sensitive tenants who want “D9 address + modern condo” at a lower absolute quantum than 800–1,100 sqft 2BRs nearby
But it can be less competitive for: – Two‑adult sharers – Small families with frequent guests – Tenants who insist on a common bath (especially in premium rentals)
In softer rental cycles, this often shows up as greater price sensitivity and potentially longer leasing times unless positioned correctly.
Harmonisation perception risk: what if tenants/agents price using 538 sqft?
Even if we believe 586 sqft is a better lived‑space comparison, leasing conversations sometimes default to published marketing sizes. That’s why the sensitivity column matters: if the market prices rent off 538 sqft, the base‑case gross yield could look closer to ~3.9% than ~4.3% in 2030 (all else equal).
Financing and carry risk: the “2030 is far away” reality
If you buy during launch/pre‑TOP, you’re also underwriting:
– Potential interest rate volatility through construction
– Changes in household income or rental demand
– The opportunity cost of capital tied up until Vacant possession
A simple mental model (not advice): if your expected gross rent in 2030 sits around ~S$5.5k/month, you’ll want to stress‑test whether the household/investor balance sheet can tolerate periods of negative carry (mortgage + fees > rent), especially in the first lease‑up year.
Practical recommendations for homeowners vs investors (without financial advice)
For potential homeowners: – If your lifestyle strongly values rail convenience + city-edge living and you’re comfortable with a single bathroom household routine, Type B1 can be a very efficient “prime core” home. River Modern’s positioning emphasises direct access to Great World MRT, which is already an operational TEL station (TEL3 opened 13 Nov 2022). If you foresee frequent guests, multi‑generation stays, or sharer scenarios, you may want to compare B1 against the 2BR types with two bathrooms within the same project (even if the price is higher), as this can materially affect day‑to‑day livability.
For investors: – Underwriting Type B1 is fundamentally about tenant pool fit and pricing discipline. The location can support a strong $psf, but the 1‑bath layout may need a sharper rent point than 2‑bath 2BRs. – Treat the gross yield math here as a screening tool. Real performance depends on vacancy downtime, leasing commissions, furnishing, MCST fees, maintenance, and the broader supply pipeline (including projects like River Green in the same lease-up window). – Consider documenting two rent strategies in advance: (1) a “fast lease” rent to minimise vacancy, and (2) a “premium positioning” rent if the market is tight during vacant possession.
