How the RERA Rental Index Works (And How Agents Should Use It)

Rent disputes are one of the most common flashpoints in Dubai's property market. Landlords want maximum yield. Tenants want protection from arbitrary increases. And agents get caught in the middle if they don't know the rules.

The RERA Rental Index is the mechanism that governs all of this. Here's how it works, how to use it, and how it should shape every conversation you have with landlords and tenants.

What Is the RERA Rental Index?

The RERA Rental Index (officially called the Real Estate Rental Index) is a government database maintained by RERA — the Real Estate Regulatory Authority, part of the Dubai Land Department — that tracks current market rental values across Dubai's residential communities.

It serves two purposes:

1. Market reference: It tells you what the market rate is for any given property type in any given area
2. Rent increase regulation: It sets the legal ceiling for rent increases on renewal under Law No. 26 of 2007 (amended by Law No. 33 of 2008)

The index is updated periodically (typically annually) to reflect market conditions. RERA gathers data from registered Ejari contracts across Dubai to determine average rental values by area, unit type, and size.

The Legal Framework for Rent Increases

Dubai's tenancy law (Law No. 26 of 2007, amended 2008) combined with Decree No. 43 of 2013 created a specific formula for permissible rent increases on lease renewal.

Here's how the increase limits work:

"Market rate" here means the figure shown in the RERA Rental Index for that specific property category in that area.

So if a tenant is paying AED 80,000 for an apartment that the index values at AED 100,000 (20% below market), the landlord can increase by up to 5% — to AED 84,000. Not by the full 20% gap, and not by whatever the landlord thinks they can get.

Key rule: The landlord must give 90 days' written notice before the lease end date to increase the rent. Without proper notice, they cannot legally increase rent on that renewal cycle.

The RERA Rental Calculator

RERa provides a free online rental calculator tool that any agent, landlord, or tenant can use: it's available at dubailand.gov.ae under the RERA Rental Index section, and also accessible through the Dubai REST app.

To use it, you input:

• Property type (apartment, villa, office, retail, etc.)
• Number of bedrooms (for residential)
• Area/community (selected from a dropdown)

The tool returns the registered market rental value for that category — the figure that determines whether and how much rent can increase.

How to Use It as an Agent

Before a landlord meeting: Run the calculator for their property. Know the index figure before they ask. This tells you immediately whether they're currently above, at, or below market — and what increases they can legally demand.

Before a tenant renewal: Run it for the tenant's property. If the landlord is trying to increase rent beyond what's legally permitted, show the tenant the RERA figure. This is their protection.

When pricing a new listing: The index gives you a market anchor. If you're pricing significantly above index, be prepared to justify the premium (renovation, views, floor level, furnished, etc.).

In a dispute: RERA's Rental Disputes Center (RDC) uses the index as the primary reference in rental increase disputes. If a case goes to the RDC, the index figure is essentially dispositive. Knowing it in advance prevents your client from wasting money on a losing case.

How Landlords Should Use the Index

The index isn't the enemy of landlords — it's a planning tool. Smart landlords use it to:

Set competitive initial rents. If you list at or slightly below index from day one, you attract quality tenants faster and reduce vacancy. A two-week vacancy on a AED 120,000 apartment costs more than the marginal rent difference.

Plan increases strategically. If your current rent is 25% below market, you can increase up to 10% per renewal cycle. That's a clear roadmap — two renewal cycles to close the gap. Communicate this timeline transparently to tenants and they're less likely to dispute or vacate.

Understand the ceiling. No matter what rents are doing in the broader market, the index figure caps what's legally enforceable. Promising a landlord they can jump from AED 80,000 to AED 110,000 in one renewal because "the market moved" is incorrect — and sets you up for a dispute.

How Tenants Should Use the Index

Tenants have as much right to the RERA calculator as landlords do. As an agent, share this openly — it builds trust and prevents the kind of disputes that consume everyone's time.

Verify any proposed increase. Before accepting a landlord's increase notice, check the index. Many landlords (or their agents) request increases above what's legally permitted, banking on tenants not knowing the rules.

File a dispute if needed. If a landlord insists on an above-index increase and won't negotiate, the Rental Disputes Center is the remedy. Filing is relatively simple, fees are modest, and the RDC moves cases through at a reasonable pace.

Understand what "notice" means legally. A WhatsApp message is not sufficient notice. Written notice — letter, email, or registered communication — 90 days before lease expiry is required. If the landlord misses this window, no increase is enforceable on that renewal.

Recent Trends in Dubai Rental Market (What Agents Are Seeing)

Dubai's rental market has been significantly above the RERA Index in many communities since 2022, as demand outpaced supply following major population inflows. This created a practical tension: market rates moved faster than the index was updated.

In practice, this has meant:

• Many tenants in long-standing leases are paying rents well below current market, but landlords can only increase by the Decree 43 formula — regardless of how far markets have moved
• Turnover tenancies (new leases, not renewals) aren't bound by the increase formula — landlords can price new lets at full market rate
• Some landlords have attempted to end tenancies by claiming personal use, then re-listing at higher rents — a practice that is illegal and subject to RDC challenge if proven

As an agent advising landlords: if their property is significantly below market and they want to close the gap quickly, the most legitimate path is working within the increase formula each renewal. Attempting to circumvent it creates legal exposure.

As an agent advising tenants: understand that renewal protection only applies to existing tenancies. When a tenant voluntarily moves, the new landlord sets price at market.

Indexed vs. Free-Market Properties

The RERA Rental Index and Decree 43 apply to residential and commercial property in Dubai governed by the tenancy law. However, some free zones (like DIFC) have their own regulatory frameworks and are not covered by Dubai tenancy law.

If you're working in DIFC properties, the DIFC Rental Disputes Tribunal and DIFC's own rules apply. Don't assume Dubai mainland tenancy law covers everything.

A Practical Scenario

Here's how this plays out in a real agent conversation:

A landlord calls you. Their tenant has been in the property for three years paying AED 85,000/year for a 2-bed apartment in JLT. Market rents for comparable units are now AED 120,000. The landlord wants to increase to AED 115,000 on renewal.

You run the RERA calculator. It shows the index figure for 2-bed apartments in JLT is AED 108,000.

The current rent (AED 85,000) is about 21% below the index figure (AED 108,000). That means the maximum permissible increase is 10% — to AED 93,500.

Not AED 115,000. The landlord's ask is legally unenforceable.

You explain this, show the calculator output, and advise: take the 10% increase now, then 10% again next year, and by year three they're at market rate — all within the law, no dispute, no vacancy.

That's what a knowledgeable agent looks like.

The Bottom Line

The RERA Rental Index isn't bureaucratic noise. It's the rulebook for an enormous share of your day-to-day agent conversations. Agents who know it cold handle disputes faster, advise clients more credibly, and avoid the embarrassment of recommending increases that will never hold up at the RDC.
