The rate you sign is not the rate you keep

The two products

Read your offer letter for two things before you sign: the reversion margin, and whether the rate is tied to 1-month, 3-month or 6-month EIBOR. A bank offering 3.75% for two years with a 2.25% reversion margin is a materially worse product than one offering 3.99% with a 1.25% reversion margin, and the second one is almost never the one on the billboard.

Which to take

There is no universal answer, but there is a decision rule that survives contact with reality:

• Fix if the payment has to be predictable. If a 1.5-point rate move would break your household budget or your 50% debt burden ratio, you are buying insurance, and insurance costs money by design.
• Go variable if you may sell or settle early. Variable products generally carry lighter exit terms and start cheaper when the curve is flat.
• Ignore rate forecasts. The dirham is pegged to the dollar, so EIBOR broadly tracks US policy. Nobody selling you a mortgage knows where that goes, including the person quoting you a five-year fix.
• Price the whole package. Arrangement fee, life insurance loading and the salary-transfer condition routinely move the effective cost by more than the 0.10% you are haggling over on the headline.

Leaving early: the cap that makes switching possible

The early settlement fee is the one consumer protection in this market that genuinely bites. Under an amendment to Appendix 2 of the Central Bank's Regulation 29 of 2011, the fee for early or partial settlement of a home loan is capped at 1% of the outstanding balance or AED 10,000, whichever is lower — a cap introduced by Board decision effective October 2019, reversing the 3% some lenders had moved to.

The practical consequence is large. On a AED 1.2M outstanding balance, 1% would be AED 12,000; the cap makes it AED 10,000. Above a AED 1M balance, the exit cost is effectively fixed in dirhams and shrinks as a proportion of the loan — which is precisely what makes refinancing a large mortgage worth calculating rather than dismissing. Note that it is a maximum, not a tariff: banks are supervised against treating it as a default charge.

The buyout, costed

Moving a mortgage to another bank in Dubai means re-running the registration machinery, not just signing a form. On a AED 1.2M outstanding balance:

Now the payback. Cutting your rate by 0.75 of a point on AED 1.2M with 25 years to run saves about AED 490 a month — around AED 5,900 a year, and a four-to-five-year break-even. That is a marginal trade. But rolling off a fixed deal onto a 2.25% reversion margin puts you near 6.2%, and moving from there to a 3.89% fix saves roughly AED 1,610 a month — the entire switching cost back inside about fifteen months.

Which is the real lesson of this page: the money in refinancing is almost never in beating today's market by a tenth of a point. It is in not sitting on a reversion rate. Put the expiry date of your fixed period in your calendar with a three-month lead, and start shopping then — not when the first higher payment leaves your account. Model both rates in the mortgage calculator before you call anyone.

Three things buried in the offer letter

1. The salary transfer condition. The best rates require your salary to land at the lending bank. If you later change employer and the salary routes elsewhere, some contracts allow a rate uplift. Ask what happens if the transfer stops.
2. Life insurance. Usually mandatory, roughly 0.3–0.8% of the outstanding balance a year, and frequently bundled into the bank's own policy at a worse price than an assignable external one. Ask for the premium as a separate number, not as part of the rate.
3. Partial prepayment allowances. Many products permit a percentage of the balance to be repaid each year without charge. Used consistently, that is the cheapest rate reduction available to you — and it needs no new valuation, no new registration and no new bank.
