Most Dubai landlords approach a renewal with one question: how much does the rental index allow? They run the calculator, find the permitted percentage and send the notice. The index answers a legal question, though, not a commercial one. It tells a landlord the most they may ask. It says nothing about what a good tenant will accept when an equivalent flat in the next building is being let for less.
That gap has become the whole problem in 2026, and it is a judgement call landlords increasingly hand to a manager. Anyone weighing Dubai property management for landlords should ask how a firm decides between a higher rent and a longer tenancy, not only how it calculates the legal maximum. The market data explains why. New-lease rents in the same building and unit type were 15.3% below January levels by August, while renewal rents had fallen only about 1%, according to fäm Properties’ analysis of Dubai Land Department data reported by Khaleej Times. In July and August, new leases outnumbered renewals for the first time since the dataset began in January 2023.
The Index Sets the Ceiling, Not the Price
Dubai’s rules on increases are specific. Under Decree No. 43 of 2013, a landlord cannot raise rent at all if the unit is let at no more than 10% below the average for similar units. Between 11% and 20% below average, the maximum increase is 5%. The cap rises in steps to 20% for rents more than 40% below average. Any change to rent terms must be notified at least 90 days before the contract ends, as Khaleej Times’ guide to rent increase notices sets out, and the tenant can take a dispute to the Rental Dispute Centre.
Since 2025, the comparison has been made through the Dubai Land Department’s Smart Rental Index, which links a building’s rental values to its star classification. DLD officials told Khaleej Times when the index launched that landlords who want to raise rents need to raise their building’s classification and rating.
All of that defines what is allowed. None of it tells the landlord whether using the full allowance is wise.
The Market Has Moved Against Renewals
For three years, renewals dominated Dubai’s rental market because moving was expensive: new leases cost more than staying put, so tenants accepted increases rather than face a higher rent elsewhere plus the cost of moving. The 2026 data shows that logic weakening. When new-lease rents fall faster than renewal rents, a tenant facing an increase can often find a comparable flat at a lower price, sometimes in the same tower.
That changes the landlord’s position. A sitting tenant used to be a captive one. Now the tenant may have a better offer on a property portal before the notice has even been read. Landlords who apply the index mechanically are, in effect, testing whether their tenant has noticed.
What a Vacancy Actually Costs
Take an illustrative apartment let at AED 120,000 a year, where the index allows a 5% increase. The rise is worth AED 6,000 a year, or AED 500 a month.
Now suppose the tenant leaves instead. One empty month costs AED 10,000 in lost rent, before any leasing fee, repainting, cleaning or the landlord’s time spent on viewings. If the new tenant signs at a rent that reflects today’s lower new-lease market, the landlord may end up below the old rent, not above it. On those numbers, a single month of vacancy wipes out the first 20 months of the increase, and a lower new rent can mean it never pays back at all.
The arithmetic does not argue against ever raising rent. It argues for treating the increase and the risk of vacancy as one decision, priced together.
Timing the Conversation
The 90-day notice is the legal minimum, not the best time to start. A tenant who first hears about an increase three months before renewal has just enough time to look elsewhere and not enough goodwill to stay. Landlords who keep good tenants tend to open the conversation earlier and informally, then follow with the formal written notice once both sides know roughly where they will land.
Order matters too. Settle any outstanding maintenance before raising the rent. A tenant who has waited six weeks for an air-conditioning repair will read an increase notice very differently from one whose last request was fixed within days.
Give the Tenant a Reason to Stay
A good tenant weighs an increase against what they get and what moving would cost them. A landlord can change both sides of that comparison. Repainting, replacing a tired appliance or upgrading worn fittings costs far less than a month of vacancy and gives the tenant something visible in return. Fast, reliable maintenance through the year does the same work more quietly.
Remember who carries the cost of moving. A tenant who leaves pays for removals, a new security deposit, agency fees and often a new Ejari and DEWA connection. A modest, well-explained increase usually sits below that total. An aggressive one often does not.
Trade Terms, Not Just Price
Rent is only one term in the contract. A landlord who wants more income and a tenant who wants stability can often meet on something other than the headline number. A smaller increase in exchange for a two-year commitment reduces vacancy risk for both sides. Accepting more cheques instead of one or two eases the tenant’s cash flow at little real cost to the landlord. Agreeing to an upgrade before the new term starts can make a full increase feel fair.
None of these changes what the index permits. They change what the tenant is willing to sign.
When Not to Raise at All
Sometimes the most profitable renewal is a flat one. If the unit is already close to the area average, the index may not allow an increase anyway. If new leases in the building are being signed below the current rent, an increase risks pushing a reliable tenant into one of those cheaper units. And if the tenant pays on time, looks after the property and has asked for nothing beyond routine maintenance, their value over the next year may be worth more than any increase the index allows.
Holding the rent is not generosity. In a falling new-lease market, it is often the higher-return choice.
Before You Send the Notice
Run through these before the 90-day deadline:
- What does the Smart Rental Index allow for this unit, and how far is the current rent from the area average?
- What are comparable units in the same building being let for today, on new leases?
- How many months of vacancy would cancel out the proposed increase?
- Is there any outstanding maintenance that should be fixed before the conversation?
- Would a longer term, more cheques or a modest upgrade get a better result than the full increase?
- Has the tenant been told informally before the formal written notice arrives?
A landlord who can answer all six is negotiating. One who has only checked the calculator is gambling that the tenant has not looked at the market.
Rent rules, the index and notice requirements are set by the Dubai Land Department and RERA, so confirm the current position with them, and check the permitted increase for your specific unit, before serving notice.
