How does selling my house instantly online impact my current mortgage?

Selling a property through an online cash-sale process changes how the buyer is found and the sale is arranged; it does not change the terms of your mortgage. The loan remains secured against the property until completion, so the sale must account for the lender’s legal and financial requirements before ownership can transfer.

An online offer is not the same as mortgage clearance. An indication of value or purchase offer does not, by itself, settle the loan. The conveyancing process still has to establish the amount required by the lender and confirm that the title can be transferred without the mortgage remaining attached to the property.

What happens to the mortgage during conveyancing? Once a sale is agreed, your conveyancer normally contacts the mortgage lender and requests the information needed for completion. This can include:

• the amount required to repay the mortgage on the proposed completion date;
• interest or other charges that may accrue before completion;
• the lender’s requirements for releasing its charge over the property; and
• details of any additional secured borrowing linked to the property.

The exact amount can change between the initial calculation and completion, particularly if the completion date moves. Your conveyancer should use the lender’s current figures when preparing the financial statement for the sale.

Your available equity determines whether the sale can complete without extra funds. Equity is broadly the property’s sale price less the mortgage and any other secured debts or sale-related amounts that must be paid. If the sale price is more than the total required for redemption and completion, the remaining funds are normally due to you after completion, subject to the conveyancer’s final account.

If the sale price is insufficient, the position is different. You may need to provide the shortfall from your own funds, or obtain the lender’s agreement to an alternative arrangement. A lender is not generally required to release its security for less than the amount owed simply because the property has been sold. Do not assume that an online buyer’s offer will cover a negative-equity position unless this has been expressly confirmed in writing.

Mortgage arrears can make the process more urgent and more complex. Missed payments, enforcement action or a repossession threat should be disclosed to the conveyancer and lender at an early stage. A sale may still require the lender to confirm how the arrears, enforcement costs and redemption amount will be dealt with. Selling before possession proceedings progress further does not automatically cancel the debt or any legal costs already incurred.

Check whether other borrowing is secured on the property. A second charge, secured loan, home-improvement finance or another restriction may also need to be repaid or formally dealt with. Unsecured personal borrowing is treated differently, but it should not be assumed that every debt connected with the home is outside the conveyancing process. Your conveyancer can identify registered charges and explain what must be cleared.

Joint mortgages require all relevant parties to be considered. Where two or more people own the property or are named on the mortgage, the sale and repayment arrangements usually require the appropriate parties to participate. Divorce, separation or disagreement over the distribution of the proceeds can delay matters even where a buyer is ready to proceed. Obtain independent legal advice if ownership, consent or the division of equity is disputed.

There may also be practical consequences for your next mortgage. Clearing the existing loan does not guarantee acceptance for a new mortgage, and a lender may assess your income, credit history, affordability and deposit separately. If you are relying on the sale proceeds for another purchase, make sure you understand when the net funds will be available and whether your onward transaction depends on a particular completion date.

Before accepting an online cash offer, ask for a clear financial breakdown. This should show the proposed sale price, any charges deducted by agreement, the estimated amount needed to redeem the mortgage, and the expected balance payable to you or required from you. The figures are subject to the lender’s formal redemption information and the conveyancer’s final statement, but a written breakdown helps identify a potential shortfall early.

It is also sensible to tell the mortgage lender that you intend to sell, particularly if the account is in arrears or the property is subject to enforcement action. Keep copies of correspondence, check whether the lender requires specific forms, and provide your conveyancer with complete details of every loan secured against the property. These steps help prevent the online nature of the transaction from creating a mistaken expectation that normal mortgage and conveyancing checks can be bypassed.
