What happens to your existing mortgage when you move house? Can you take it with you, or should you look for a cheaper deal? Our guide explains the options

Key takeaways

  • When buying a new home you need to decide whether to transfer (port) your existing mortgage to a new property or pay it off and take out a new one

  • Transferring your existing mortgage to a new home means you keep your current interest rate, but be sure to check if your mortgage is portable

  • Be aware of early redemption charges, exit fees, arrangement fees, booking fees, valuation fees, broker fees, and conveyancing costs when applying for a new mortgage

When it comes time to sell your home, one of the most significant decisions you'll face is what to do with your mortgage.

It's not just about finding a buyer and moving out; it's also about figuring out the financial implications of transferring your mortgage to a new property or settling it and starting fresh.

This decision can be complex, with various factors influencing the best course of action. It's not just about the numbers; it's about your future plans, current financial situation, and the terms of your existing mortgage.

Getting a mortgage for a new home

What are my mortgage options when moving home?

When you move home, there are two main options available when it comes to your mortgage:

You can transfer, or 'port', your mortgage to a new home. This can be a smart move, especially if you're currently benefiting from a low-interest-rate deal.

You can pay off your old mortgage and take out a new one. This could be the case if you're moving to a significantly more expensive property or if you want to take advantage of a better mortgage deal.

Porting your mortgage to a new home

One of the main benefits of porting your mortgage is the potential to keep your existing low-interest rate, which can save you from the fees associated with taking out a new loan. However, not all mortgages are portable, so it's crucial to check the details of your mortgage agreement.

If you're unsure whether your mortgage is portable, consult your mortgage documents or speak with a broker. They can help you understand the terms of your mortgage and whether porting is an option for you.

If your mortgage isn't portable, you'll need to apply for a new mortgage when you sell your house. This process involves reapplying and undergoing various checks, and you may need to pay for a property valuation, legal fees, and possibly stamp duty.

Keep in mind that changes in your financial circumstances since you took out your original mortgage could affect your approval for porting. If porting isn't possible, you'll need to consider getting a home mover mortgage.

When applying for a new mortgage, lenders will perform credit and affordability checks to ensure you can manage the loan. Be aware that you may face early redemption charges if you're paying off your existing mortgage before the end of your deal period.

How can I borrow more money?

If you're moving to a more expensive property, you might need to borrow additional funds, and potentially pay higher mortgage payments. Here are three options for borrowing more money:

  • Increase your existing mortgage – You can ask your current lender if you can borrow more on your existing mortgage. You may be able to do this via online or mobile banking.

  • Port your mortgage and take out an additional loan – If your mortgage is portable, you can transfer it and apply for a top-up loan.

  • Pay off your existing mortgage and get a new one – This option may be suitable if you're looking for a better deal or if your current deal isn't portable.

The additional amount you can borrow will depend on a few factors, such as your credit score. Try our mortgage calculators to check your eligibility and see what your options may be.

What’s the best option for my mortgage?

Moving house is a big financial decision and the best option for your mortgage will depend on your own personal situation. The following are all key points to consider when weighing up your options:

If your mortgage is portable, you can move to a new house without changing your mortgage. This is simpler if the value of the new home is the same or less than your current mortgage. If you need to borrow more, ensure the repayments are manageable.

Usually, changing mortgages means paying off the existing one, which can incur early repayment charges if you're still locked into a deal.

Using the equity in your home as a deposit for your next property is a common strategy. This involves selling your current home and using the profit as a down payment for the new property, which can influence your mortgage options.

If you're downsizing, you may be able to reduce your mortgage repayments, especially if your financial situation hasn't changed. It's even possible to buy a cheaper home mortgage-free if you have enough equity.

Porting your mortgage to a cheaper property can be a sensible option if you don't need to borrow additional funds. However, be mindful of the Loan to Value (LTV) percentage, which could increase and affect lender expectations.

Moving house when in negative equity is challenging. It's essential to consult with your mortgage provider to understand your options, as getting a new mortgage can be difficult and may come with restrictions.

If there's a delay between selling and buying a new property, contact your mortgage provider about the possibility of porting within a certain timeframe. If the move isn't immediate, you might need to look for a new mortgage deal.

Moving house with a mortgage - things to consider

What fees will I pay when taking out a home mover mortgage?

If you decide not to port your mortgage, you may incur extra fees when taking out a new mortgage. These can include:

  • Early redemption charges

  • Exit fees

  • Arrangement fees

  • Booking fees

  • Valuation fees

  • Broker fees

It's important to factor in these costs when deciding on the best mortgage option for your move, along with other fees such as conveyancing.

Get life insurance when you move house

For many homeowners, having financial protection in place makes sense. Life insurance can provide a financial safety net for your family, ensuring they're not burdened by mortgage payments if the unexpected happens. Learn more about our life insurance options.

You can also use our our mortgage re-payment calculator to see what your repayments will be based on how much you’re borrowing, the interest rate and fees of the deal, and how long you will have to pay it off for.
