How does the 50% DBR rule work for a UAE mortgage?
Last updated: · By Aknaz Mortgages, RERA ORN 48584
The 50% debt-burden ratio (DBR) rule caps your monthly debt repayments, including the new mortgage, at half of your gross monthly income. Banks also apply their own internal stress rate, so the instalment they test can be higher than your actual one, which lowers the most you can borrow.
Key numbers
| Rule | Value |
|---|---|
| Maximum debt-burden ratio (all monthly repayments ÷ gross monthly income) | 50% |
| Maximum loan-to-value, expat first home below AED 5,000,000 | 80% |
| Maximum loan-to-value, expat first home at AED 5,000,000 and above | 70% |
| Maximum mortgage term | 25 years |
| Age at the end of the term, expats | 65 |
| Fixed rate for 1 year | from 3.75% |

What counts towards the 50% DBR?
Every regular monthly debt repayment counts towards the 50% debt-burden ratio, together with the new mortgage instalment. The ratio compares those repayments with your gross monthly income, which is your pay before deductions. If the total is within the limit, the DBR test is passed. If it is above the limit, the bank must reduce the loan until it fits.
Typical commitments are car loans, personal loans, existing mortgages, student loans and the minimum payments on other credit. Only repayments that are certain and recurring are included, which is why a bank reads your credit report and bank statements before it decides.
Which limit applies first?
The lower of two limits applies: the DBR-limited loan and the loan-to-value (LTV) limit, which is the largest share of the property price a bank will lend. A bank calculates both and approves the smaller, so there is no fixed order and no single rule that always decides.
In practice, the DBR usually decides for borrowers with existing commitments, because every dirham of debt cuts into the 50% allowance. The LTV limit decides when the property is the limit, such as a modest purchase price for a high earner, and it sets the minimum deposit. For an expat buying a first home below AED 5,000,000, the LTV limit is 80%, so the deposit is at least the rest of the price.
The table below lists the LTV limits for each type of buyer. The DBR-limited loan is not in the table, because it depends on your own income, debts, term and rate.
| Buyer and property | Price below AED 5,000,000 | Price AED 5,000,000 and above |
|---|---|---|
| Expat, first home | 80% | 70% |
| UAE national, first home | 85% | 75% |
| Second property (first one mortgaged) | 60%, varies by bank | |
| Non-resident | salaried 60–65%, self-employed 50–60% (up to 65% with some banks); varies by bank. | |
| Off-plan | 50% | |
How do banks stress-test the rate?
Banks apply their own internal stress rate, which affects your DBR eligibility and the maximum loan. Instead of testing the instalment at the rate you will start paying, a bank may test it at a higher rate, to check that you could still afford the loan if rates rose. The test rate differs by bank and by product.
A stress test works on the same principle as the debt-burden ratio: it asks whether your income can carry the repayments in a worse case. If the bank applies a higher test rate, the loan it will approve falls, even when your actual starting rate is lower. That is one reason two banks can give different answers for the same salary.

Frequently asked questions
Is the DBR calculated on gross or net salary?
The debt-burden ratio is measured against gross monthly income, which is your salary before deductions. Banks use the income shown on your payslip and salary statement, so the instalment you can be approved for may feel high against the money that actually reaches your account.
Do the DBR and the loan-to-value limit both apply to the same loan?
Yes. A bank checks the debt-burden ratio and the loan-to-value limit on the property, then approves the lower of the two results. Which one decides depends on your salary, your existing debts, the price of the home and the term you choose.
How do existing loans change my maximum mortgage?
Every monthly repayment you already have, such as a car loan or personal loan, is added to the debt-burden calculation. That reduces the room left for the new instalment, so the DBR-limited loan falls. We check how each bank counts your commitments before anything is submitted.
Can a longer term raise the amount I can borrow?
The term affects the instalment and therefore the loan, within limits. It is capped at 25 years and must usually end by age 65 for expats, although some banks allow 70 and selected banks 75. We work out the right term for your age and bank.
