The Real Cost of an Agent Over a 10-Year Holding Period
How much does an agent actually cost over 10 years of renting out a property?
Roughly five months' worth of rent, paid away in commission — about S$16,350 on a S$3,000/month unit re-let through an agent every time a tenant moves out, over a 10-year holding period. That figure never appears as a lump sum anywhere, because it's billed one small transaction at a time, which is exactly why it's worth adding up once.
The Council for Estate Agencies (CEA) sets no fixed commission rate — "there are no fixed commission rates nor prescribed guidelines on commission amounts" (CEA, Renting or renting out, checked 22 September 2026). What exists instead is a market convention, and it's the same one Rentora's own agent fee calculator runs on: roughly half a month's rent per year of lease on the landlord's side. On a S$3,000/month unit and a 1-year lease, that's S$1,500 before GST. Add 9% GST — the rate IRAS confirms has applied to standard-rated supplies invoiced or paid for on or after 1 January 2024 (IRAS, Overview of GST Rate Change, checked 22 September 2026) — and the bill for that single transaction is S$1,635.
Landlords rarely sign one lease and stop. Assume the same unit gets re-let to a new tenant every year for a decade, with a landlord's agent involved each time: S$1,635 × 10 = S$16,350 over 10 years, before any tenant-side fee is added on top.
Does a 2-year lease cost less than renewing every year?
No — the 10-year total comes out identical either way, which is the counterintuitive part. A 2-year lease costs more per transaction (1 month's rent instead of half a month, since the convention scales with lease length) but happens half as often. On the same S$3,000/month unit:
| Lease length | Fee per re-let (incl. 9% GST) | Re-lets in 10 years | 10-year total | |---|---|---|---| | 1 year | S$1,635 | 10 | S$16,350 | | 2 years | S$3,270 | 5 | S$16,350 |
The math cancels out because the convention is half a month's rent per year of lease — a 2-year lease simply charges two years' worth in one go. Over any fixed holding period, the total commission works out to about 5 months' rent (before GST) transferred to agents, whether that's collected in ten small payments or five larger ones.
That holds only if a fresh agent fee is actually charged at each re-let. If the same tenant renews in place — no move-out, no new tenancy — many agents don't charge again, since there's no new transaction to facilitate. Worth confirming in writing before signing, since the Estate Agency Agreement is what actually governs it, not the convention.
How much does the total change with the rent level?
Proportionally — the 10-year cost is roughly 5.45% of one year's rent, multiplied by ten, regardless of lease length:
| Monthly rent | 10-year agent cost (landlord's side only) | |---|---| | S$2,000 | S$10,900 | | S$3,000 | S$16,350 | | S$4,000 | S$21,800 | | S$5,000 | S$27,250 |
These are the same 0.5-month, 9%-GST assumptions Rentora's agent fee calculator uses, so you can run it against your own rent, lease length and holding period rather than relying on the table above.
What if the tenant pays their own agent too?
Then the total roughly doubles. Since 1 July 2024, the Singapore Estate Agents Association's (SEAA) Best Practice Guide for Co-Broking Commission has encouraged each agent to be paid by the client they actually represent — landlord's agent by the landlord, tenant's agent by the tenant — rather than the two splitting one commission. As of February 2025, 70 estate agencies representing about 90% of registered real estate salespersons in Singapore had adopted it (CEA, Key Things to Know about the SEAA Best Practice Guide for Co-broking Commission, checked 22 September 2026). It's a best-practice guide, not a regulation, so adoption varies by agency and by listing — but where both sides do engage separate agents on a S$3,000/month unit re-let annually, the combined 10-year total comes to roughly S$32,700 instead of S$16,350.
Does GST make a material difference over 10 years?
Yes, on its own it's a few thousand dollars. On the S$3,000/month, 1-year-lease example above, the pre-GST base over 10 years is S$15,000; the 9% GST adds S$1,350 on top, for the S$16,350 total. Not every agency charges it — GST only applies where the agency itself is GST-registered — so it's worth asking whether a quoted figure already includes it before comparing quotes.
How much of your total rental income does that represent?
About 4.5%, on the numbers above. A landlord collecting S$3,000/month for 10 straight years takes in S$360,000 in gross rent (3,000 × 12 × 10, before any vacancy). Against that, S$16,350 in agent commission works out to roughly 4.5% of everything the property brought in over the decade — not a one-off line item, but a recurring slice of gross income that compounds every time the unit turns over. Add a tenant-side agent fee on the same terms and it climbs to around 9%. Neither figure moves much with rent level, since both the income and the commission scale with the same monthly rent.
That's before accounting for vacancy between tenants, which agents don't guarantee against either — the Estate Agency Agreement covers finding and facilitating a tenant, not compensating for the weeks a unit sits empty.
Does going direct avoid this cost entirely?
Yes, structurally — there's no agent on either side to pay. That's the premise behind a direct landlord-to-tenant platform like Rentora: the eligibility checks, the tenancy agreement and the stamp duty filing happen without a middleman charging a running commission to coordinate them over the years you hold the property. It doesn't remove IRAS stamp duty, which is a tax on the tenancy itself and applies whether or not an agent is involved — only the commission disappears.
Q&A
Is this the same number as a single lease's agent commission? No — this is the commission added up across every re-let over a 10-year holding period, not one transaction. A single 1-year lease on a S$3,000/month unit costs S$1,635, not S$16,350; the larger figure only appears once you hold the property and re-let it repeatedly.
Does the fee still apply if the same tenant just renews? Usually not, if there's no new tenancy signed and no new agent engagement — but confirm this in the Estate Agency Agreement rather than assuming it, since the agreement is what's enforceable, not the general convention.
Is there a cap on how much an agent can charge across a long relationship? No. CEA sets no ceiling any more than it sets a fixed rate — the limit is whatever is negotiated and documented in writing before each engagement.
Does the 10-year figure include stamp duty or other taxes? No — it's commission only. Stamp duty is calculated separately and is owed to IRAS regardless of whether an agent is involved; see Rentora's stamp duty calculator for that figure on your own tenancy.
