How Much Mortgage Can You Afford in the UAE? The Full Calculation

Mortgage affordability in the UAE is easily calculable, because all three constraints are written into the Central Bank regulation. Here is the full arithmetic; our free Mortgage Affordability Calculator runs it for your numbers instantly.

Constraint 1: The DBR, with a stress test

All monthly debt commitments (proposed mortgage instalment plus car loans, personal loans, and roughly 5% of credit card limits) must fit within 50% of gross salary plus regular income. The general rule is covered in the CBUAE 50% DBR cap explained; the mortgage twist is the stress test. The regulation requires lenders to test the instalment at 2 to 4 percentage points above the offered rate. Offered 4.25%? The bank checks whether you'd still be under 50% at roughly 6.25 to 8.25%.

Constraint 2: LTV caps

The Central Bank caps how much of the property's value a bank can finance: 80% for expat residents on a first home up to AED 5 million (85% for UAE nationals), lower tiers above AED 5 million and for second properties, and 50% for anything off-plan. The full grid is in LTV caps and down-payment rules. LTV binds against the lower of purchase price and bank valuation, which matters when a bank values a property below the agreed price.

Constraint 3: Tenor

Maximum 25 years. Banks additionally require the loan to finish by roughly age 65 (salaried) or 70 (self-employed) under their own policies, so a 50-year-old effectively gets a 15-year tenor, which raises the instalment and cuts the affordable loan sharply.

Worked example: Omar, AED 30,000/month, no other debt

Step 1: DBR headroom. 50% × 30,000 = AED 15,000/month maximum instalment.

Step 2: Apply the stress test. At an offered 4.25% over 25 years, AED 15,000/month would service about AED 2.77 million. But stressed at 7.25%, that same AED 15,000 only services about AED 2.08 million. Banks apply their internal version of this test; in practice Omar's approvable loan lands around AED 2.2 to 2.5 million depending on the lender's stress margin.

Step 3: Check LTV. At 80% LTV, a AED 2.4 million loan supports a property of AED 3.0 million, requiring AED 600,000 down.

Step 4: Check cash, not just income. The down payment is not the full cash need. Transaction costs add roughly 6 to 7% of the property price (DLD transfer fee, mortgage registration, valuation, bank and agent fees), and since early 2025 banks can no longer roll these fees into the loan, so they must come from savings. On Omar's AED 3 million purchase that's roughly AED 200,000 on top of the AED 600,000 deposit; the full breakdown is in mortgage fees and hidden costs.

What moves the number most

In order of impact: existing debt (a AED 2,000/month car loan removes roughly AED 300,000 to 350,000 of mortgage capacity), tenor (each lost 5 years cuts capacity noticeably), then rate. Cutting unused credit card limits before applying is the cheapest capacity gain available, with the credit file trade-offs noted in what hurts your AECB score.

The two gates beyond affordability

Affordability is necessary, not sufficient. Your AECB file must clear the bank's risk bar (working comfort zone around 700 for mortgages, detailed in minimum AECB scores by product), and your income must be verifiable: salary, or documented business or rental income. End-of-service benefits cannot be counted.

A planning note

The 50% DBR is the regulatory maximum. A mortgage at the ceiling leaves no buffer for rate resets, job changes, or life. Most planners aim nearer 30 to 35% of income for housing debt; the calculator shows both figures so you can choose deliberately.
