Passive Income from a Private Condo

The base case

A freehold three-bedroom private condo in the Clementi or Commonwealth corridor, bought at about $1.8 million, is the starting point for every strategy below. The numbers come from a computed model, not a broker's pitch.

Property tax is the hinge of the whole analysis. If you rent out the whole unit, you lose the owner-occupier concession and the bill jumps from about $3,470 to $13,500 a year, a delta of roughly $10,030. That is the single biggest hidden cost of whole-unit letting. IRAS property tax rates and owner vs non-owner rates confirm the progressive gap.

The eight strategies

Each strategy carries a legality verdict, a yield, and a modelled monthly cashflow. The winner for a family that actually lives in the unit is not the one with the biggest headline rent.

Legality follows the URA short-term accommodation rules and the HDB room-rental cap for the six-person limit. The short-term rule is unchanged in 2026.

Whole-unit letting: legal but negative-carry

Renting out the entire condo is straightforward and legal, but in 2026 the yield sits below the cost of debt, and you give up the owner-occupier tax concession.

Gross yields in the corridor run about 3.0 to 3.5 percent: Clementi 3.28%, Queenstown 3.35%, Commonwealth 3.06%, Holland 2.98%. On a $1.8M unit that is roughly $4,950 a month. PropertyGuru rental yield data and 99.co yield analysis track these figures.

After the non-owner-occupier property tax of $13,500, the mortgage-interest deduction of $20,250 and the 15% deemed expense of $8,910, the net taxable income is about $30,240, which lands near $208 of income tax. The net cashflow is negative, around −$834 a month. You are building equity, but the unit does not pay for itself. IRAS rental income and IRAS deductible expenses set the tax spine.

A corporate or expat lease (Strategy 4) is the best whole-unit option, carrying a 5 to 15 percent premium on 1 to 3 year terms and a 3.0 to 3.8 percent yield. At $5,250 a month the net cashflow improves to about −$534. ❓ The premium range is inferred from typical expat-leasing practice rather than a single published figure.

Rent out spare rooms: the winner for a family that lives there

If you live in the condo, renting out spare rooms keeps the owner-occupier concession on the full annual value, which is the whole trick.

Room letting is legal under the six-person cap, or eight with a 90-square-metre registration. Clementi and NUS-area rooms run about $1,300 to $1,600 a month for a common room and $1,300 to $2,500 for a master. PropertyGuru room rentals and HDB occupancy rules support the range.

Because you keep the owner-occupier rate on the full annual value, you save roughly $10,000 a year in property tax versus whole-unit letting. The mortgage interest is apportioned by rooms rented over total rooms, and the 15% deemed-expense shortcut still applies. One common room at $1,400 a month drops housing cost from about $4,948 to $3,548; two rooms at $3,600 drop it to about $1,348. IRAS room-letting treatment confirms the owner-occupier concession is retained.

Co-living master lease: guaranteed but thinner

Handing the whole unit to a co-living operator trades management effort for a guaranteed rent, at the cost of a lower yield and the owner-occupier concession.

Co-living is legal for sublets of three months or more. Operators such as Cove run 500-plus properties, but there is no confirmed Clementi or Commonwealth location, as the portfolio is city-fringe focused. Cove lists its locations and terms. ❓ The absence of corridor coverage is inferred from the operator's published city-fringe footprint.

Terms run two to three years with a guaranteed rent and an operator cut of roughly 10 to 20 percent. At a guaranteed $4,500 a month, the net cashflow is about −$1,284, the weakest of the legal whole-unit options. ❓ The operator-cut range is inferred from typical co-living fee structures.

Short-term letting: illegal, do not do it

The three-month minimum-stay rule is unchanged in 2026, which makes Airbnb-style letting illegal for a private residential condo.

Fines run up to $5,000, with heavier penalties and court action for repeat or multi-property offenders. This strategy is not modelled because it is not a real option. URA short-term accommodation guidelines and URA media releases document the rule and penalties.

Student, ancillary and commercial income

Three smaller or adjacent paths round out the list. Two are real for this unit; one is a separate purchase.

Student rental (Strategy 6). Near NUS, the same room rates apply as in Strategy 2, with high seasonal demand in Clementi and identical tax treatment. PropertyGuru room listings show the corridor's student demand.

Ancillary income (Strategy 7). Parking runs $150 to $400 a month with MCST approval, storage about $100 a month, and a helper room about $800 a month. HDB season passes cannot be sublet. ❓ The parking and storage ranges are inferred from typical condo ancillary fees. These stack on top of Strategy 2.

Mixed-use commercial (Strategy 8). Commercial-grade yield of 4 to 6 percent is only available on strata-titled commercial units, not a standard residential condo. It is a separate purchase path, not something this unit can do. IRAS property tax treats commercial and residential differently.

The tax spine

The tax rules decide which strategies are worth doing. The short version: whole-unit letting costs you the concession, room letting keeps it, and the deductions nearly wipe out income tax.

Sources: IRAS property tax rates, IRAS rental income, IRAS deductible expenses, and IRAS GST.

Macro context

Prices are still rising but moderating, and mortgage rates sit near three-year lows. The cooling measures are unchanged.

Private prices rose 0.5% quarter-on-quarter in Q2 2026 and 1.4% in the first half, with mortgage rates at three-year lows around 1.6 to 2.0 percent fixed and SORA bottoming near 1%. CBRE sees 2 to 4 percent full-year growth. URA price index releases and CBRE Singapore insights track the trend.

Cooling measures are unchanged: ABSD, LTV and TDSR still apply, the SSD was tightened in July 2025 from three to four years, and the 15-month wait-out was removed on 28 July 2026. MAS cooling measures and IRAS SSD document the rules.

The numbers, charted

Three charts pull the model together: net monthly cashflow by strategy, the property-tax gap between owner and non-owner occupation, and the housing-cost reduction from room letting.

The honest verdict

For a family that lives in the condo, the answer is clear. For a family that is moving out, the calculus changes.

Strategy 2 is the winner. Renting out spare rooms keeps the owner-occupier concession, saves about $10,000 a year in property tax, and cuts housing cost from roughly $4,948 to $3,548 with one room or $1,348 with two. Add Strategy 7 on top.

Whole-unit letting is negative-carry in 2026. Strategies 1, 3 and 4 all run between −$534 and −$1,284 a month because yields of 3 to 3.5 percent sit below the cost of debt, and you lose the concession. It only makes sense if you are moving out anyway and want to keep the asset and build equity.

Short-term letting is illegal. The three-month rule is unchanged. Never do it.

Co-living is a management trade. Strategy 3 only if you want zero management and accept a lower guaranteed yield, and there is no confirmed corridor coverage.

The tax deductions are the hidden upside. The interest and 15% deemed-expense claims nearly eliminate income tax on rental income, which is the quiet reason renting out pays better than it looks.

Commercial yield is a separate purchase. If you want 4 to 6 percent, that is a strata-commercial unit, not this condo.

What to do next

A short checklist before you act, so the numbers hold up against your actual unit.

• Verify the room-rental cap for your specific unit (six-person, or eight with the 90sqm registration).
• Get an AV-based property-tax quote from IRAS for both owner and non-owner scenarios.
• Check the MCST rules for subletting parking and storage.
• Compare co-living operator coverage for the Clementi and Commonwealth corridor before committing.
• Confirm the mortgage-interest apportionment with your bank and a tax adviser.
