Every tenant in Dubai has done the envelope math: "my rent is 120,000 a year, a mortgage on the same apartment would be 110,000 — renting is burning money." Sometimes the conclusion is right. The math never is. Here is how to do it properly.
The mistake: rent vs instalment
A mortgage instalment mixes two different things: interest (a true cost, like rent) and principal (forced saving — money moving from your bank account into your equity). Comparing rent to the whole instalment overstates the cost of renting. But owners have their own version of the error — forgetting every cost that is not the instalment.
The true annual cost of owning
For a fair comparison, add up what owning actually consumes each year:
- Interest on the loan (not principal)
- Service charges — in many Dubai buildings a substantial four- or five-figure annual sum
- Maintenance the landlord used to cover — a common rule of thumb is around 1% of property value a year
- Insurance — building/contents and the life cover your bank requires
- Amortised purchase costs — the roughly 7% you paid upfront in cash (the 4% DLD fee, about 2% agency, valuation, arrangement and registration fees) spread over your realistic holding period
- Opportunity cost of the deposit — your 20%-plus down payment could otherwise be invested; what it would plausibly earn is a real cost of choosing to own
Against that, owning earns you: principal repayment (equity build), any property appreciation, and immunity from rent rises. Renting's side of the ledger: the rent itself, plus the returns on the capital you did not lock into a deposit.
The variable that decides most cases: time
Purchase costs are the reason time horizon dominates this decision. That ~7% upfront cost is sunk the day you buy; sell within a couple of years and it rarely has time to be offset by equity growth and rent avoided. Hold five, seven, ten years and it amortises into irrelevance while principal repayment compounds. The honest generalisation:
- Under ~3 years in the property: renting usually wins.
- Past ~5 years: buying usually wins, and the margin grows with every year and every rent increase.
- In between: the details decide — run your own numbers.
"Time in the property" is the phrase, not "time in Dubai" — buying, outgrowing the place in two years, and selling repeats the transaction costs. Buy the home for the next chapter, not just the current one.
The Dubai-specific factors
- Rent volatility is real. Renters carry repricing risk at every renewal; owners on a fixed rate carry none, and even variable-rate owners (how those move) are hedged against the rental market specifically.
- Rates change the answer. The interest component is the biggest owning cost; compare today's actual market rates rather than a remembered number from two years ago.
- Yields vary by community. High-yield areas are, by definition, areas where rent is expensive relative to price — which tilts those communities toward buying. Low-yield prime areas tilt the other way.
A worked sketch
AED 1.5M apartment, 80% loan, illustrative interest around 4–4.5%: first-year interest lands roughly AED 50,000–54,000. Add, say, AED 15,000 service charges, AED 10,000 maintenance/insurance, ~AED 15,000 of amortised purchase costs (7% over seven years), and perhaps AED 12,000 forgone on the AED 400,000+ of cash deployed. True cost of owning: roughly AED 100,000–105,000. If renting the same unit costs AED 110,000–120,000 — buying wins from year one, before any appreciation. At AED 85,000 rent, renting wins today and buying is a bet on rent inflation and price growth. That is the calculation — everything else is mood.
