The most argued question at every UAE dinner table, answered with arithmetic instead of opinions. Model both paths over your own horizon: the mortgage, the fees, the rent rises, and what a disciplined renter's investments would grow into.
Computed: DLD transfer 4% AED 72,000 · agency 2% + VAT AED 37,800 · registration AED 3,600 · admin AED 5,000
Computed: agency commission 5% of the first year’s rent, AED 6,000
Sensitivity. The answer flips to renting if appreciation drops below 0.74% per year (you assume 3%). The closer those two numbers are, the less confident you should be.
Most rent-vs-buy arguments fail because the two sides count different things. This model counts everything, on both sides, symmetrically.
The calculator simulates both lives month by month and compares net position: what you own minus what you owe, at the end of each year. Each month, whichever side pays less for housing invests the difference, so both paths spend exactly the same cash and the comparison stays fair.
The buyer's path. At month zero the buyer pays the down payment plus the one-off buying costs. Every month after that they pay the mortgage instalment, computed with standard amortizationAmortization: the fixed monthly payment that repays a loan over its term. Early payments are mostly interest; later ones are mostly principal., plus service charge, maintenance and insurance (held flat, in today's dirhams). Their asset is the home: its value compounds at your appreciation rate, and equity is that value minus the remaining loan balance.
The renter's path. At month zero the renter pays only the agency fee (the deposit is refundable, so it is excluded), and invests the cash the buyer just spent: the down payment plus buying costs go straight into a portfolio earning your investment return. Every month they pay rent, which steps up once a year at your rent-inflation rate. Their asset is the portfolio.
The symmetry rule. Early on, owning usually costs more, so the renter keeps adding to the portfolio. If rent inflation eventually pushes rent above the owner's costs, the flow reverses and the buyer invests the surplus.
What the model leaves out, deliberately: selling costs at exit (another ~2% agency if you sell, which pushes the real break-even slightly later), the refundable rental deposit, moving costs, and rental income (this compares living in the home, not landlording). There is no property tax or capital gains tax in the UAE, which genuinely tilts the math toward buying compared with most countries. Returns are applied at one twelfth of the annual rate each month; rent steps annually; property value compounds annually.
The sticker price is not the price. Between signing and getting the keys, roughly 7-8% of the property's value goes to fees, and none of it builds equity.
The big line is the DLD transfer feeDLD: Dubai Land Department. Its 4% transfer fee is charged on every property sale, ready or off-plan, and is usually paid by the buyer in practice. at 4% of the purchase price, payable at transfer. On an AED 1.8M apartment that is AED 72,000 gone before you own a single tile. Agency commission adds 2% plus 5% VAT, another AED 37,800. If you take a mortgage, the DLD charges 0.25% of the loan to register it, and the bank wants a valuation (AED 2,500-3,500) plus assorted admin, trustee-office and no-objection fees. Some banks also charge an arrangement fee up to 1% of the loan, which you can often negotiate down or roll in. Call the entry toll 7-8% of the price all-in; the calculator's default of about 6.6% is the conservative core (DLD, agency, registration, valuation) and you can edit the lump to match your own quote.
Owners then discover the costs renters never see. Service charges fund the building: cleaning, security, chiller plants, the pool you use twice a year. In Dubai they typically run AED 10-30 per square foot per year, so a 1,200 sqft apartment can cost AED 12,000-36,000 annually just to sit in a maintained building. Add maintenance of the things inside your walls, roughly 1% of the property's value per year averaged over AC replacements and repainting, plus AED 2,000 or so of home insurance. None of this is optional, and all of it lands on the owner's side of the ledger.
This is why buying starts behind in the chart above. The buyer begins the race carrying the toll, and only appreciation, principal repayment and rising rents pull the buy line back over the rent line. The horizon slider decides whether they get enough years to do it.
The rent path only wins on paper if the renter actually invests the difference. Most do not, and that single fact decides more rent-vs-buy outcomes than any interest rate.
Be honest with the sliders: if you know you will not invest the difference, set the investment return to 0% and watch the verdict. For an undisciplined renter, buying often wins not because property is a great asset, but because it is the only savings plan they will actually follow.
Look at the model again: the renter's entire case rests on a portfolio built from the down payment they never paid and the monthly gap they never spent. A mortgage is many things, but above all it is forced savings. Every instalment quietly buys a slice of the home whether you feel disciplined that month or not. Renting has no such mechanism. The AED 478,000 the default renter keeps in year one has a way of becoming a nicer car, a longer summer, a lifestyle that expands to fit the cash.
The fix is to make investing as automatic as a mortgage would be. Set a standing instruction that moves the difference the day your salary lands, before you can see it. Park the near-term portion where it still earns: current UAE savings accounts pay meaningfully different rates for the same dirhams, and the gap between a lazy account and a good one is real money at this scale. Put the long-term portion in diversified, low-cost investments and let time do the compounding; if you want the intuition for why the renter's portfolio can outrun property at all, how compounding works walks through it.
Away from the knife edge, some situations are not close. If several of these describe you, you probably do not need the calculator to tell you the answer.
Spread the 7-8% entry toll over 15 years and it barely matters; over 3 years it is ruinous.
If annual rent runs 7-8% of the price, you are handing your landlord more than a mortgage would cost.
If the difference would in truth be spent, a mortgage is the one savings plan you will actually follow.
Under roughly five years, the entry and exit costs almost never earn themselves back.
Paying the bank more than the landlord would charge is speculation wearing a homeowner's clothes.
Emptying every account for the deposit leaves you illiquid in a country where visas follow jobs.

An educational model, not financial advice.
This tool illustrates the arithmetic of one decision under assumptions you control. Real outcomes depend on the actual property, the mortgage offer in front of you, fees that vary by bank, developer and emirate, and market movements nobody can forecast. Appreciation and investment returns are not guaranteed and can be negative for years at a time. Before committing, get the bank's full fee schedule, the building's service-charge history, and independent advice for your situation.
Before you compare paths, see what a UAE bank would actually lend you, and what it costs per month.
