Every mortgage calculator asks the same question: what monthly payment can you afford? The bank asks three questions, and applies whichever gives the smallest answer.
This is why the amount you are actually offered so often comes as a shock.
The three ceilings
- Debt Burden Ratio (DBR). All your monthly debt — the new mortgage, car loans, personal loans, and a slice of your credit card limits — must stay within 50% of gross income. This is what binds most people.
- Loan-to-Value (LTV). The loan cannot exceed a set percentage of the property price. For an expat buying a first home under AED 5 million, that is 80%.
- Income multiple. Financing is also capped at roughly seven times annual income.
Being comfortable on one and blocked on another is entirely normal. It is the lowest of the three that decides your number.
Find your actual limit
The UAE Mortgage Affordability Calculator applies all three Central Bank limits and shows which one is binding you.
The stress test nobody mentions
Banks do not assess you at the rate you are quoted. They add roughly three percentage points and check that the higher payment still fits inside the 50% limit. A loan quoted at 4.25% is underwritten at about 7.25%.
This single rule is why the bank's offer is routinely 20% smaller than a simple payment calculator suggests. Most online calculators mention the stress test in their text and then quietly fail to apply it in the maths — which is why their numbers look so much more generous.
Your empty credit cards are costing you a house
Banks count 5% of your total credit card limit as a monthly commitment — whether or not you owe a single dirham on it.
A card with an AED 100,000 limit therefore eats AED 5,000 of your monthly debt allowance before you borrow anything. On a AED 30,000 salary, that is a third of your entire DBR headroom, consumed by a card sitting unused in a drawer.
In practical terms, AED 100,000 of unused card limits can cost you roughly AED 690,000 of borrowing power. Cutting those limits is often faster and more effective than a pay rise. Allow up to six months for the change to show on your Al Etihad Credit Bureau record.
Age quietly shrinks your loan
The loan must normally be repaid by around age 65 if you are salaried, or 70 if self-employed, with a maximum term of 25 years regardless.
So a 50-year-old salaried buyer is limited to a 15-year mortgage, not 25. Shorter term means higher monthly payments, and through the DBR that cuts borrowing power substantially — from roughly AED 2.08 million down to AED 1.64 million on the same income. Every year you wait costs you.
Deposits
- Expat, first home up to AED 5m — 20%
- Expat, first home above AED 5m — 30%
- UAE national, first home up to AED 5m — 15%
- Second or investment property — 40%
- Off-plan, anyone — 50%
And remember the fees — roughly 7% of the price — sit on top and cannot be financed. Work out the full cash requirement with the Property Purchase Cost Calculator before you commit.
How to increase what you can borrow
- Cut unused credit card limits. Usually the single biggest lever.
- Clear short-term loans before applying — car and personal loans eat DBR directly.
- Do not wait. Age shortens the term and shrinks the loan.
- Talk to a broker. Banks apply their own policies on top of the Central Bank rules, and some are more lenient on the rule that happens to be limiting you.
