Property ManagementOne Month of Vacancy Erodes Almost the Entire Gain
Your neighbour just re-rented at a higher rate. Your tenant pays on time and never calls about a burst pipe. Before you raise the rent, run the number most landlords skip: what a vacancy actually costs against the increase.
Direct Answer
A rental increase only clearly pays off if your current tenant accepts it, or a replacement tenant is found almost immediately. On a S$4,300 unit with a 10% increase, a tenant who stays nets you S$10,320 over 24 months. But if the tenant leaves and it takes even one month to re-let, agent commission and lost rent cut that gain to roughly S$36 a month. Two months of vacancy turns the increase into a net loss. The math favours retaining a good tenant at a moderate increase over chasing market rate at vacancy risk.
Where the 2026 Market Actually Stands
Singapore private rents ended 2025 up 1.9% for the year, reversing 2024's 1.9% fall (Rentify). The median monthly rent for private homes is around S$4,300 (Relocity). Rent growth in 2026 is expected to stay moderate, helped by limited supply and slowly rising demand (ERA). Rents dipped 0.5% quarter on quarter in Q4 2025, the usual year-end softness, before the full year closed positive. So you have some pricing power in 2026, but it's limited. If your rent is already at or near market, the case for a big increase is weak. If you've been below market for two years, a moderate correction makes sense, and the numbers below show how much.
The Five Scenarios, Side by Side
Assumptions: current rent S$4,300, proposed 10% increase to S$4,730, agent commission on a new 2-year lease at one month's rent (S$4,730), 24-month lease term.
| Scenario | Net over 24 months | Net per month |
|---|---|---|
| Tenant accepts the increase | +S$10,320 | +S$430 |
| New tenant found immediately | +S$5,590 | +S$233 |
| New tenant found in 1 month | +S$860 | +S$36 |
| New tenant found in 2 months | −S$3,870 | −S$161 |
| New tenant + S$2,000 reno contribution | −S$1,140 | −S$48 |
A rent increase only clearly pays off when your tenant stays, or a new one moves in almost immediately. In 2026's steadier market, you can't count on that. New tenants increasingly ask for fresh paint or a new appliance before signing, and a S$2,000 contribution like that is enough on its own to turn a one-month vacancy into a loss.
Three Variables That Move the Result
What Actually Changes the Calculation for Your Unit
Your current rent versus market rate. If you're 15% to 20% below market, a correction is justified even after a month of vacancy, because the gap is real and it keeps growing. If you're already at or above market, the upside is small and the downside grows fast.
Your location and demand profile. A 2-bedroom near an MRT interchange attracts replacement tenants faster than a 3-bedroom in a suburban OCR location without direct MRT access. Know where your unit sits in the demand hierarchy before assuming a fast turnaround.
Your tenant's profile. A tenant of 4-plus years who has personalised the space and has children in nearby schools carries high switching costs. A tenant of 2 years is more mobile. This stickiness changes the real probability of each scenario above.
The Honest Verdict
Most landlords do better keeping a good tenant at a moderate increase, or even no increase, than chasing market rent and risking two empty months. One month of vacancy wipes out almost all of a 10% increase over a 24-month lease. Two months turns it into a loss. In practice: if your tenant has been reliable, offer a modest 3% to 5% rise and present it as keeping pace with inflation, not opportunism. Most good tenants would rather accept a fair increase than move. If you're well below market, catch up in steps; 10% now and more at the next renewal keeps tenants better than one 15% to 20% jump. And if your tenant has already said they're looking elsewhere, price to fill the unit fast. An empty unit always costs more than a slightly lower rent.

Frequently Asked Questions
Should I raise my tenant's rent at renewal in 2026?+
It depends on how your current rent compares to market and how sticky your tenant is. If you're already near market rate, a significant increase risks a costly vacancy. If you've been 15-20% below market for a while, a moderate, phased correction is usually justified.
How much does a vacancy actually cost when raising rent?+
On a S$4,300 unit raised 10% to S$4,730, one month of vacancy plus agent commission cuts a 24-month gain of S$10,320 down to roughly S$860 -- about S$36 a month. Two months of vacancy turns the increase into a net loss of about S$3,870 over the lease term.
What percentage rent increase is reasonable for a good tenant?+
A modest 3-5% increase framed as inflation-linked, rather than opportunistic, tends to retain reliable tenants better than a sharp jump. Most good tenants will accept a reasonable adjustment rather than deal with the cost and disruption of moving.
Do new tenants ask for renovation contributions in Singapore in 2026?+
It's becoming more common. New tenants in a stabilising market sometimes negotiate a one-time contribution -- new curtains, fresh paint, or an updated appliance -- as a condition of signing, which can offset a meaningful share of any rent increase.
How do I know if my rental unit is priced below market?+
Compare against recent transacted rents for similar units in your building or immediate vicinity, factoring in unit size, floor, and condition. If you've held the same rate for two years or more without adjustment, it's worth checking -- the market has moved even if your rent hasn't.
