Fixed or variable: choosing a UAE mortgage rate type
Sarah ChohaibAuthorPublished 6 August 2026 · Last updated 23 August 2026
Choose a fixed rate if you need payment certainty or you are borrowing near your affordability ceiling; choose variable only if you expect EIBOR to keep easing or you will sell or refinance within about three years. In the UAE the decision hinges less on the headline rate than on the reversion margin — commonly EIBOR plus 1.5 to 2.5 percentage points — that applies once the fixed period ends.
How each product actually works
| Fixed | Variable | |
|---|---|---|
| Instalment | Locked for 1–5 years | Resets with EIBOR, usually quarterly |
| Pricing | Flat rate, e.g. 3.89% | Bank margin + 3M EIBOR |
| After the intro period | Reverts to margin + EIBOR | Continues on margin + EIBOR |
| Best for | Certainty, stretched affordability | Short holding period, falling rate view |
Almost every UAE fixed mortgage is a variable mortgage with a fixed period attached. That is why the reversion margin matters as much as the introductory rate — it is the rate you will actually be paying for most of a 25-year term.
Why EIBOR is the number that decides variable pricing
The dirham's peg to the US dollar means the UAE Central Bank's rate broadly tracks the US Federal Reserve, and EIBOR follows with a short lag. EIBOR has eased from its 2023 peak as the Fed's cutting cycle has played out, which has pulled variable-rate instalments down for borrowers already on that product. That direction of travel is not a guarantee for any specific quarter — EIBOR can also rise if the rate cycle turns — so a variable choice should be a deliberate view on rates, not a default.
The five-year test
Run every offer over five years, not over the fixed period. A one-year fixed at 3.89% reverting to EIBOR + 1.99% will usually cost more across five years than a five-year fixed at 4.24% unless EIBOR falls materially and stays there. If you cannot see the reversion margin in writing, treat the offer as incomplete — ask for it before comparing rates across banks.
| Product | Year 1 | Years 2–5 (illustrative) | 5-year total |
|---|---|---|---|
| 1-year fixed at 3.89%, reverts to EIBOR + 1.99% | AED 125,160 | ~AED 132,000/yr | ~AED 653,000 |
| 5-year fixed at 4.24% | AED 129,720 | AED 129,720/yr | AED 648,600 |
Worked example: a AED 2.4M loan, two paths
Consider a buyer taking a AED 2,400,000 loan over 25 years. Path one is a three-year fixed at 4.09%, reverting to EIBOR + 1.90% for the remaining 22 years. Path two is a five-year fixed at 4.24%, reverting to EIBOR + 1.65% for the remaining 20 years. The three-year fixed instalment is roughly AED 350 a month lower in year one, which looks like the obvious choice on paper.
| Product | Years 1-3 | Years 4-6 (illustrative) | 6-year total |
|---|---|---|---|
| 3-year fixed 4.09%, reverts EIBOR + 1.90% | AED 452,700 | ~AED 158,400/yr | ~AED 927,900 |
| 5-year fixed 4.24%, reverts EIBOR + 1.65% | AED 778,320 | ~AED 153,700/yr | ~AED 932,100 |
The two paths land within roughly AED 4,000 of each other over six years, despite an apparent 15 basis point gap on the headline rate. The narrower reversion margin on the five-year product does most of the work closing that gap. This is the calculation most borrowers never run because the headline fixed rate is the only number the bank leads with in conversation.
Islamic fixed and variable equivalents
Sharia-compliant lenders offer the same structural choice under different naming: a fixed profit rate for an introductory period under an Ijara or Murabaha contract, reverting to a variable profit rate benchmarked to EIBOR plus a margin. The decision framework is identical — compare the introductory profit rate, the length of the fixed period and the reversion margin, and run the same five-year test before choosing between a conventional and an Islamic offer.
When variable genuinely wins
- You plan to sell inside three years and want to avoid early settlement friction on a longer fixed product.
- You are refinancing an equity release you intend to repay quickly.
- Your income comfortably absorbs a 200 basis point rate move without breaching your own comfort margin, not just the bank's 50% debt burden ratio cap.
Split mortgages: fixing part of the loan
A small number of UAE banks allow a split structure, fixing a portion of the loan and leaving the rest on variable within a single facility. This suits a borrower who wants partial certainty without giving up all exposure to a falling-rate environment — for example, fixing 60% of a AED 3,000,000 loan and leaving 40% variable. It is not offered on every panel bank and the pricing on each portion is usually slightly worse than committing fully to one structure, so ask your broker whether it is available before assuming it is the default option.
How to decide: a short checklist
- 1Write down your holding period. Under three years leans variable or a short fixed; five-plus years leans a longer fixed.
- 2Ask for the reversion margin in writing before comparing any two offers on their fixed rate alone.
- 3Stress test your instalment at a 150 to 200 basis point increase to see if it still fits comfortably inside your budget, not just the bank's DBR cap.
- 4Check the early settlement terms if there is any chance you refinance or sell before the fixed period ends.
- 5Re-run the comparison three months before any fixed period expires, using the current EIBOR rather than the number in your original offer letter.
A quick note on rate comparison sites
Generic rate comparison tables, including the one on this site, are refreshed periodically and are always indicative. They are a useful starting point for narrowing which two or three banks to approach, but the number that matters is the one in your own written offer letter, checked against your actual LTV, income and employer.
What a rate shock actually looks like
Assume you took a variable mortgage on a AED 1,800,000 balance at EIBOR + 2.00% when 3-month EIBOR was near 4.00%, an effective 6.00%. If EIBOR rises by 100 basis points at the next quarterly reset, your effective rate moves to 7.00% and the monthly instalment rises by roughly AED 1,050. Stress testing that move against your budget before you choose variable, not after the first reset lands, is the single habit that prevents a rate shock from becoming a payment problem.
Switching later: rate switch vs buyout
If you choose fixed now and market pricing improves later, you are not locked in forever. A rate switch with your existing bank or a mortgage buyout to a new lender are both available once the fixed period ends, or in some cases earlier subject to the regulated early settlement cap. Both carry fees, so the decision comes down to the same five-year maths used to choose the product in the first place.
