When Selling Your Home, What Happens When Your Mortgage Is Higher Than Your Sale Proceeds?

Selling a property usually feels like a win. The buyer is ready, contracts have been exchanged, and settlement is approaching. However, there is one issue that can quickly turn a straightforward sale into a financial challenge. If the amount owing to your lender is greater than the net sale proceeds, the bank will not simply “write off” the difference. The shortfall must be paid before the mortgage can be discharged.

In New South Wales, a property cannot be transferred to a purchaser until any registered mortgage over the title has been paid out. If the sale price, after adjustments and costs, is not enough to clear the loan, the vendor must contribute the difference. Without those additional funds, the outgoing lender may refuse to release its mortgage, causing settlement to be delayed.

This is why early financial calculations are so important. The final settlement figure is not simply the sale price less the mortgage balance. Council rates, water charges, strata levies, mortgage payout figures, legal fees, agent commissions and other adjustments can all affect the amount available at settlement. The Financial Settlement Schedule within PEXA helps identify whether there will be a surplus or a shortfall before settlement takes place.

Common Reasons a Vendor May Need to Contribute Additional Funds

SituationWhy It Matters
Mortgage exceeds sale proceedsThe lender will require the full loan balance to be repaid
Softening market conditionsA lower sale price may create a funding shortfall
Outstanding rates or leviesThese reduce the funds available at settlement
Multiple secured loansMore than one loan may need to be discharged
Agent commissions and legal costsSelling expenses can affect the final balance
Settlement adjustmentsRates, water and strata adjustments may alter the final figures

From a seller’s perspective, discovering a shortfall late in the process can be stressful. A vendor may believe the sale is progressing smoothly, only to find out shortly before settlement that additional funds are required. This can place pressure on moving plans, create financial strain and potentially expose the seller to contractual risk if settlement cannot proceed on time.

The good news is that shortfalls can often be managed smoothly when identified early. Funds may be transferred into a trust account before settlement and then directed into the PEXA workspace at the appropriate time. This enables the mortgage payout to be completed, the lender’s mortgage to be released and the transaction to proceed without unnecessary delays.
