Property expense ratio for a Singapore rental condo typically runs 18–28% of gross rental income — property tax (10% of annual value for non-owner-occupied), MCST management fees, repairs, agent commission on tenanting (typically half-month for 1-year lease), and income tax on the net rental are the main components.
Singapore rental property looks deceptively simple on a yield basis — 3.5% gross often quoted, before any costs are deducted. In practice, the gap between gross and net yield is significant: property tax alone is 10% of annual value for non-owner-occupied residential, and MCST fees, repairs, depreciation, and agent commissions further compress the net. Understanding the expense ratio is what separates landlord arithmetic that works from arithmetic that looks good on paper.
Singapore property tax has been progressively raised across multiple Budgets since 2022, with the non-owner-occupied rate flat at 10% of annual value (AV) since 2024 (as of 2026-05). For higher-AV properties (above S$30k AV), the 2026 schedule still applies a progressive structure with the top tier at 27% for owner-occupied premium properties. This means yield modelling must use the correct tax tier for the rental scenario.
What Does It Mean?
Expense Ratio
The percentage of gross rent set aside for vacancy periods, repairs, agent fees, and other recurring costs. A typical expense ratio is 10-20% of gross rental income.
Condo Management Fee
Monthly condo management fee paid to the MCST (Management Corporation Strata Title) for building maintenance, security, and facilities.
Property Tax
Annual property tax in Singapore. Non-owner-occupied residential properties are taxed at progressive rates from 12% to 36% of the Annual Value (estimated annual rent).
How Is It Calculated?
Expense Ratio
A 15% expense ratio on $3,800/mo rent = $6,840/year in expenses.

Worked example: S$1.5M leasehold condo rented out at S$4,200/month (3.36% gross yield).
| Line item | Annual (S$) | % of gross rental |
|---|---|---|
| Gross rental | 50,400 | 100% |
| Property tax (10% × AV S$48,000 estimated) | 4,800 | 9.5% |
| MCST maintenance (typical S$320/month) | 3,840 | 7.6% |
| Repairs & replacements (allowance) | 1,800 | 3.6% |
| Agent commission on tenanting (half month, 1-yr lease) | 2,100 | 4.2% |
| Building insurance (fire only, mandatory) | 200 | 0.4% |
| Income tax on net rental (assume 15% marginal) | 5,640 | 11.2% |
| Total expense | 18,380 | 36.5% |
| Net rental income | 32,020 | 63.5% |
Net yield = S$32,020 / S$1,500,000 = 2.13%. The gross-to-net haircut here is 36.5% — within the typical 18–28% band for a more efficient unit, but pushed higher by the 15% marginal income tax assumption. Lower-income landlords see a smaller tax drag.
- Calculate net yield, not gross — the gross-to-net difference is at least 18%; often 25%+ once income tax is included.
- Know your AV — IRAS publishes property AV, used for property tax. AV is reviewed periodically and tends to rise with market rents.
- Budget repairs at 3–5% of rental annually — AC servicing, plumbing, paint touch-ups, occasional appliance replacement.
- Optimise agent fees — direct-let via PropertyGuru or 99.co listings saves the half-month commission but adds your time. Repeat tenants save the most.
- Document everything for income tax — every expense reduces taxable rental income; IRAS allows itemised or 15%-of-rental simplified deduction.
Frequently Asked Questions
Is property tax different for owner-occupied vs rented?
Yes — owner-occupied rates are tiered from 4% up to 24% (top tier for AV > S$140k), much lower than the flat 10% for non-owner-occupied.
Can I deduct mortgage interest from rental income?
Yes. Mortgage interest on the rental property is deductible against rental income for tax purposes. Capital repayments are not deductible.
What's the simplified 15% deduction option?
Instead of itemising every expense, IRAS allows a flat 15% of rental income as deductible expenses (plus mortgage interest). Most efficient for landlords with low actual expenses.
Does MCST fee usually rise over time?
Yes — typically 2–4% per year as the building ages and sinking fund contributions are reviewed. Older developments often see step-changes when major works (e.g., re-painting, pool refurbishment) require fund replenishment.
What if the unit sits vacant for months?
You still pay property tax, MCST, and insurance. Property tax can be reduced via the IRAS Vacant Property Rebate (request within prescribed time, typically with proof) — partial refund of tax for verified vacancy.
