Joint Mortgage in the UAE: Buying With a Co-Borrower

A co-borrower can increase the income a lender assesses, but the debts of both borrowers count too, and each lender sets its own policy on joint applications.

A joint mortgage in the UAE lets two people apply together so the lender can assess both incomes, which can raise the amount you qualify for. The Central Bank regulation (CBUAE "Regulations Regarding Mortgage Loans", C 31/2013) does not set a specific rule for co-borrowers: each lender sets its own policy on who can be a co-borrower and how incomes are combined. What the regulation does fix is the framework: the 50% debt burden ratio applies to the incomes and debts that are assessed (Article 3.1), and each borrower can claim only one property as a first home (Article 3.2).

What the regulation covers

Income and debts are assessed together

Article 2.2 asks lenders to collect "a full income and liabilities history for each applicant". If two people apply, the lender looks at both incomes and both sets of debts. Article 2.3 lists what is taken into account: other debt payments (including credit cards), security of employment and household expenditure. Only reliable and sustainable income counts, with bonuses discounted.

The DBR (Article 3.1)

The maximum DBR is 50% of gross salary and regular income, and lenders should not apply the maximum automatically. The loan is stress tested 2 to 4 percentage points above the loan rate.

The income multiple (Article 3.4)

Up to 7 times annual income for expatriates and 8 times for UAE Nationals. How a lender applies this to two applicants (for example on the combined assessed income) is part of its own policy: ask your lender.

One first home per borrower (Article 3.2)

In the first home / owner occupier category, "each borrower can only claim one property". If one co-borrower already uses that category for another property, the lender may treat the new loan under the second-home limit (60% for expatriates, 65% for nationals). Check with your lender how it applies this to your file.

Worked example: one income vs two incomes

Assumptions (examples): Borrower A earns AED 22,000 a month with a car loan of AED 3,000; Borrower B earns AED 13,000 with a credit card payment of AED 1,000. Stress rate 6% (example rate 4% + 2 points), 25 years, all income counted, no household allowance. Expatriates, first home.

On a property of AED 2,400,000 (first home, 80% LTV cap = AED 1,920,000), the couple could fit a loan of AED 1,920,000 in this example, while A alone would be limited to about AED 1,242,000. The monthly payment on AED 1,920,000 at an example rate of 4% over 25 years is about AED 10,134.

Note that Borrower B's credit card payment reduces the joint room: a second income always comes with its own debts.

Practical points before applying together

1. Ask each lender for its co-borrower policy: who can be added and how incomes are combined.
2. List both sets of debts: credit cards, car loans and personal loans all count (Article 2.3).
3. Fund the down payment from own resources (Article 2.4), not personal loans or credit cards.
4. Check the first-home status of each borrower (Article 3.2).
5. Read the loan documents together: each borrower signs each page and receives a copy signed by both parties (Article 4).
6. Plan costs: 4% DLD transfer fee (usually paid by the buyer in practice), 0.25% of the loan for mortgage registration + admin fees, AED 250 title deed, trustee office fee AED 4,000 + VAT.

What the loan documents must show you both

Article 4 of the regulation protects every borrower, and in a joint application it protects both of you:

• Total cost: the lender must set out the total cost of the loan over its lifetime.
• Fee schedule: all fees and charges in a separate schedule attached to the contract, with the method used to calculate interest or profit.
• Key terms: property details, your contribution, loan amount, repayment period, instalment, rate, insurance requirement, disbursement method and a clear pre-payment policy.
• No unilateral changes: the lender cannot alter the terms during the loan unless the borrower agrees in writing, and fee changes require at least two months' notice.
• Refinancing: there should be no impediment to refinancing with another institution, and early repayment or refinancing charges are capped at the lender's actual break cost and/or the fees in Regulation 29/2011.

These protections matter if your situation changes later, for example if one of you wants to repay early or refinance. See your rights in the mortgage contract.

FAQ

Does a co-borrower always increase the loan?

Not always. A second income adds capacity, but the second borrower's debts reduce it, and each lender decides how it combines incomes.

Can two expats buy together with a mortgage?

The regulation does not prohibit it; the decision depends on each lender's policy. The same LTV, DBR and income caps apply. See also mortgages for salaried expats.

Can a UAE National and an expatriate apply together?

The regulation does not address mixed applications. Ask your lender which LTV and income cap it applies; nationals' rules are in our UAE Nationals guide.

What happens if one of us is self-employed?

That borrower's income is verified and weighted as described in our self-employed mortgage guide.
