The bank lends on value, not price
Your loan-to-value is applied to the bank's valuation, not the price you agreed. If you offer AED 2.0M but the valuer says AED 1.9M, the bank sizes the mortgage off 1.9M — and you cover the AED 100k gap in cash on top of your deposit.
What the valuer looks at
Recent comparable transactions in the same building/community, the unit's size, floor, view and condition, and current market trends. Off-plan handovers and unique units are harder to comp and can swing more.
Who pays + when
The buyer's bank instructs a RERA-approved valuer once your mortgage application is in motion; the buyer typically pays the valuation fee (a few thousand dirham). It happens before final loan approval, so it can reshape the deal late.
A down-valuation is a financing gap, not a deal-breaker
If the valuation comes in low, you can pay the difference in cash, renegotiate the price with evidence, or — if your MOU allows — withdraw. Knowing the comps before you offer is the best defence.
