Smart Rental Index 2026: why a portfolio-wide renewal sheet is wrong by construction
Last updated: 18 September 2026. Written for landlords and property managers operating units in Dubai. This is operational guidance, not legal advice — verify every figure against the Dubai Land Department (DLD) calculator for the specific unit before you serve a notice.
Most landlords with 30–600 units still run renewals off one spreadsheet column: a single percentage applied across a building or a portfolio, sanity-checked once against the RERA calculator. That method worked when the index was a community average. In 2026 it no longer describes the thing it is trying to approximate.
What changed in 2026 (the short version)
- The index moved from broad community averages to sub-community and cluster-level tracking, so two buildings in the same community can carry different benchmarks.
- Furnished and unfurnished units are indexed separately, with studio categories added in communities where studio supply grew.
- A building classification system (reported as a 1–5 star rating driven by technical and service criteria) feeds whether a unit can justify an increase at all.
- The permitted-increase bands themselves (Decree 43 of 2013) are unchanged: the gap between your current rent and the indexed average determines the cap, from 0% up to 20%.
Consequence, stated plainly: the cap is a property of the unit, not of the building or the portfolio. A single percentage applied across 40 units will be too high on some (illegal, and a gift to the tenant at the Rental Disputes Centre) and too low on others (money you never collect and cannot retroactively claim).
The Decree 43 bands, as they apply at renewal
| Your current rent vs the indexed average | Maximum increase | |---|---| | Less than 10% below | 0% — no increase permitted | | 11%–20% below | 5% | | 21%–30% below | 10% | | 31%–40% below | 15% | | More than 40% below | 20% |
The bands are applied to the indexed average for that unit's category — which, from 2026, is a sub-community, furnished/unfurnished, size-and-type-specific figure. Change the category inputs and you change the band, not just the number.
The one rule that kills most increases: 90 days
An increase or any change of terms at renewal requires 90 days' written notice before the contract expiry date, unless the parties agree otherwise in writing. Miss it and the contract renews on the same terms. In a 60-unit portfolio with expiries spread across 12 months, that means roughly 5 notice deadlines a month, each of which has to be calculated, evidenced and served — not remembered.
This is why we treat the notice calendar as a compliance artefact, not a reminder: date of service, method of service, and the exact index figure used, stored per unit.
The per-unit renewal method (what to actually do)
Step 1 — Fix your Ejari hygiene first. The index is built from registered contract data. If your Ejari records carry the wrong furnishing status, unit type, size or building name, the calculator returns the wrong benchmark for your own unit. Bad registration data sets your own future cap. Audit furnishing status and unit type across the portfolio before renewal season, not during it.
Step 2 — Run the calculator per unit, and screenshot it. Dubai REST app or the DLD portal. Record: date of check, inputs used, indexed average returned, band, resulting maximum. That screenshot is the evidence that your notice was lawful — it costs nothing today and is very expensive to reconstruct later.
Step 3 — Split furnished and unfurnished in your own rent roll. If your system stores furnishing as a free-text note, you cannot compute caps in bulk. It is a field, and it must match Ejari.
Step 4 — Sequence by expiry, not by building. Sort all units by expiry − 90 days. Work that queue. Buildings are an accounting convenience; the law runs on contract dates.
Step 5 — Decide per unit whether to take the cap. The maximum is not the answer. A 20%-capable unit with a 4-year tenant, zero arrears and a clean cheque history may be worth 5% and a renewal; a 0%-capped unit in a weak building tells you the asset, not the tenant, is the problem. That decision needs per-unit net figures — rent minus service charge, maintenance, vacancy and collection cost — which is exactly the number most portfolio spreadsheets never produce.
What we could not verify (and will correct)
- We found no single official DLD page publishing the full 2026 building-classification criteria and their weights in a citable form. The 1–5 star description and the criteria list appear across secondary market sources (agency and brokerage publications, May–June 2026), not in a primary document we could locate.
- The often-quoted "furnished units index 20–40% higher than unfurnished" figure is a market estimate from secondary sources, not an official band. Do not put it in a notice. Use the calculator output for the actual unit.
- Reported 2026 benchmark shifts for specific communities (JVC, Business Bay, Dubai Marina, Dubai Creek Harbour) come from secondary market commentary and move over time — always re-check live.
If you hold a primary DLD source that corrects any line on this page, send it to us and we will update the page and credit the correction.
FAQ
Does the Smart Rental Index apply one cap per building? No. From the 2026 update the benchmark is tracked at sub-community and building level, with furnished and unfurnished units indexed separately, so caps are computed per unit and category rather than per building.
Can a landlord and tenant agree a rent above the indexed cap? A written mutual agreement above the indexed figure is reported to be permissible in practice, but it remains open to later challenge at the Rental Disputes Centre. Document agreement in writing and keep the index check on file.
How much notice is required to raise the rent in Dubai? 90 days in writing before the expiry of the current contract, unless both parties agreed a different period in writing. Without valid notice the contract renews on existing terms.
Does furnishing a unit raise the legal cap? It changes the category the unit is indexed against, which can change the benchmark and therefore the band. The change must be reflected in the registered contract, and the calculator output for that unit is the only figure to rely on.
What evidence should a landlord keep for a rent increase? The dated calculator output with the inputs used, the registered contract details, and proof of how and when the 90-day notice was served.

Where Rent360 fits — and where it doesn't. Rent360 is built for the landlord/operator side: per-unit renewal calendars with the 90-day gate, per-unit P&L so the "take the cap or not" decision has a number behind it, PDC cheque lifecycle, and a dated evidence ledger for anything that later goes to the Rental Disputes Centre. It is not the right tool if you need a brokerage/listings CRM, a full accounting ERP, or owners-association/service-charge administration as your primary system. We are invite-only while we onboard pilots; the free cost audit at /audit is the front door.
