How does having a fixed-rate mortgage affect the sale of my house?

Having a fixed-rate mortgage does not prevent you from selling your house, but it can affect the amount you receive from the sale and the decisions you need to make about timing. The key issue is whether the mortgage is redeemed during the fixed-rate period and what your mortgage terms say about doing so.

Check the exact terms of your mortgage. Your mortgage offer and annual statements should identify the date on which the fixed-rate period ends, any early repayment conditions, the balance owed and any permitted overpayments. The charge for repaying during the fixed period may be calculated according to your lender’s specific formula, so do not rely on a general estimate. Ask the lender for a written redemption statement based on the expected completion date.

A redemption statement is important because the balance shown on an ordinary mortgage statement may not be the exact amount required to close the account. The redemption figure can take account of interest up to a specified date, applicable charges and any other amount due under the mortgage. It is normally obtained by your conveyancer or solicitor as part of the sale process and may need to be updated if completion is postponed.

Calculate your expected net proceeds. Start with the anticipated sale price, then deduct the mortgage redemption figure and the other costs connected with the transaction. These may include conveyancing costs, estate agency charges if you use an agent, removal expenses and any applicable mortgage-related fees. This calculation will show whether the sale is likely to leave you with funds to put towards your next home or whether you need to arrange additional finance.

Fixed-rate mortgages can also affect the timing of a move. If the sale completes before the fixed period expires, the lender’s early repayment terms may apply. If completion takes place after the fixed period ends, the mortgage may move to the lender’s follow-on rate unless another arrangement has been made. The relevant date is generally the date the mortgage is redeemed, not simply the date you instruct an agent or accept an offer, so confirm the position with your lender and conveyancer.

Do not assume that selling the property automatically ends every mortgage obligation. Until completion takes place and the lender receives the required funds, you remain responsible for the mortgage under its existing terms. If the sale is delayed, continue making the contractual payments and check whether the updated redemption figure has changed. Your conveyancer will usually arrange for the lender’s legal charge to be dealt with from the completion funds.

Before marketing the property, it is sensible to:

• confirm the fixed-rate end date and the lender’s repayment conditions;
• request an indicative redemption figure for budgeting purposes;
• ask whether the lender applies administration or discharge fees;
• check whether any overpayments or other account adjustments affect the balance;
• obtain an up-to-date statement if the expected completion date changes; and
• give your conveyancer the lender’s details at the start of the transaction.

If the expected sale price is close to the amount needed to redeem the mortgage, obtain professional advice before committing to the transaction. A conveyancer can check the legal requirements, while the lender can confirm the precise amount needed on the proposed completion date. Where timing or the property’s condition makes a conventional sale difficult, a UK cash buyer may be another route to consider, but the mortgage still needs to be properly accounted for and settled as part of completion.
