6.2 Transaction Model 4: Mortgage Buyer with Mortgaged Seller (Inter-Bank Settlement)

6.2 Transaction Model 4: Mortgage Buyer with Mortgaged Seller (Inter-Bank Settlement)

In the Dubai property market, a significant percentage of secondary transactions involve properties with an existing encumbrance being purchased by a buyer who also requires mortgage financing. This structure is designated as Transaction Model 4: Mortgage Buyer with Mortgaged Seller (Inter-Bank Settlement).

Model 4 is widely recognized by conveyancing professionals as the most intricate transaction model in Dubai real estate. It requires simultaneous coordination among eight separate stakeholders: the Buyer, the Buyer's Bank, the Seller, the Seller's Bank, the Master Developer, the Listing Broker, the Buyer's Broker, and the Real Estate Registration Trustee acting under the authority of the Dubai Land Department (DLD).

1. Operational Complexity and Timeline Architecture

Unlike cash conveyancing (Model 1: often 1 to 3 weeks) or single-encumbrance models (Model 2: often 25 to 45 days; Model 3: often 3 to 5 weeks), Model 4 transactions typically take 4 to 8 weeks (30 to 60 calendar days) from contract to transfer. These are market norms, not legal deadlines.

This extended timeline stems from the structural challenge inherent in Dubai property law: a property cannot be transferred to a new buyer while encumbered by an existing mortgage, yet the buyer's lending bank cannot advance long-term mortgage funds without securing first-priority legal charge over the underlying asset.

To bridge this gap safely, the UAE banking sector and DLD have established standardized inter-bank settlement protocols governed by strict commercial instruments and regulatory releases.

2. The Seller's Liability Letter (Bayan Madyouniya)

The procedural cornerstone of Model 4 is the Liability Letter (also termed a Payoff Letter or Settlement Certificate), requested by the seller from their existing mortgagee bank.

Essential Components of the Liability Letter

An enforceable Liability Letter issued by a UAE Central Bank-regulated institution must state:

1. Outstanding Principal Balance: The exact principal debt remaining on the mortgage facility.
2. Early Settlement Fees: Prepayment fees, which under Central Bank consumer regulations are capped at 1% of the outstanding balance or AED 10,000, whichever is lower (plus 5% VAT).
3. Accrued Interest and Daily Rate: Interest calculated to a specific date, accompanied by a specified daily interest accrual rate (per diem) to account for transit days.
4. Settlement Account Details: The bank's designated internal settlement account and IBAN for receiving payoff funds.
5. Strict Expiry Date: The letter carries a fixed validity window, typically 15 to 30 calendar days from the date of issuance.

Handling Negative Equity

If the seller's outstanding loan exceeds the agreed price (negative equity), the seller must fund the shortfall, for example by paying it to the bank or providing a manager's cheque for it, because the bank releases the mortgage only when the debt is paid in full.

3. The Inter-Bank Settlement Workflow

The settlement of the seller's debt is executed through direct institutional channels between the two commercial banks:

Step-by-Step Chronology

Step 1: Form F Execution with Extended Timelines

The brokers draft Unified Form F with special conditions reflecting Model 4 complexity:

• A completion timeline of at least 45 to 60 calendar days.
• An express mortgage contingency clause for the buyer (typically 20 business days).
• An explicit covenant obligating the seller to apply for and deliver a valid Liability Letter within 7 business days of the buyer receiving the Final Offer Letter.

Step 2: Buyer Valuation and Final Offer Letter (FOL)

The buyer's lender conducts the independent RICS valuation. Upon approval, the buyer signs the binding FOL and pays bank processing fees.

Step 3: Liability Letter Generation

The seller pays their bank's documentation fee (typically AED 200 to AED 500) and obtains the official Liability Letter.

Step 4: Payoff Cheque Issuance by Buyer's Bank

The buyer's bank inspects the seller's Liability Letter. To settle the debt, the buyer's bank issues a UAE Bank Manager's Cheque made payable strictly to the Seller's Bank:

• Scenario A (Buyer Loan $\ge$ Seller Liability): The buyer's bank draws the settlement cheque entirely from the buyer's approved mortgage proceeds.
• Scenario B (Buyer Loan < Seller Liability): If the buyer's approved loan is smaller than the seller's outstanding debt (for example, buyer is borrowing AED 1,200,000 but seller owes AED 1,500,000), the buyer must provide a personal Manager's Cheque for the difference (AED 300,000) drawn in the name of the Seller's Bank. Both cheques are presented simultaneously to clear the total liability.

Step 5: Loan Clearance and Mortgage Release

The settlement cheque is delivered to the seller's bank against an official stamped acknowledgment of receipt. The seller's bank processes the payoff through its clearing accounts, which typically requires 3 to 7 business days.

Once funds clear, the seller's bank:

1. Issues a clearance (no-liability) letter confirming that the debt is settled.
2. Issues the mortgage release letter, which is submitted to DLD so that the release can be registered (DLD charges AED 1,290 for the release procedure and AED 315 to the registrar).
3. Returns any original security documents to the seller.

4. Developer NOC and Final Trustee Closing

With the seller's mortgage discharged, the property is unencumbered, enabling the final closing sequence:

Developer No Objection Certificate (NOC)

The seller applies for the developer NOC, presenting the mortgage clearance certificate alongside proof of zero service charge balances on Mollak. The developer issues the e-NOC, which is valid for a short period.

Transfer Day at the Registration Trustee Office

All stakeholders convene at an authorized Real Estate Registration Trustee office:

1. The Buyer and Seller (or authorized POAs)
2. Both Licensed Brokers
3. The Buyer's Bank Mortgage Representative

Execution of Simultaneous Actions

At the Trustee office, the registrar executes the final financial and legal settlement:

• Disbursement of Remaining Equity:
  • The buyer's bank representative brings a Manager's Cheque for the net remaining loan balance payable to the Seller (Total Approved Loan minus Payoff Cheque previously issued to Seller's Bank).
  • The buyer brings a Manager's Cheque for the remaining cash equity payable to the Seller (Purchase Price minus Total Approved Loan minus Security Deposit previously paid).
• Payment of Government and Registration Fees: the DLD 4% sale fee, the fixed title deed and map fees, the trustee fee (AED 4,000 + VAT at AED 500,000 or more), the mortgage release fees (AED 1,290 plus AED 315 to the registrar) and the new mortgage fee of 0.25% of the loan; DLD waives the separate registrar fee for the new mortgage when it is registered the same day.
• Release, sale and new mortgage in one sequence: DLD's service description states that once the release letter is submitted, DLD completes the mortgage release, the sale and the new mortgage. Under Law No. 14 of 2008 the buyer's bank's mortgage takes effect on registration and ranks by its registration order.
• Title Deed Issuance: DLD generates the new electronic Title Deed in the buyer's name, annotated with the new mortgage lien in favor of the buyer's lender.
