How your mortgage changes when you upgrade or downsize your home

Mortgages

As life changes and living arrangements follow suit, you may find yourself needing – or wanting – to upsize or downsize your home.

Perhaps you’ve a growing family or have just had a promotion with a wage increase and feel it’s time to upgrade. Or maybe your children have flown the nest, or you’re preparing for retirement and want to downsize.

Whatever your reasons for moving on, how this impacts your current mortgage depends on many variables.  

Impact on mortgage amount

When homes are outgrown, a new, bigger home will typically cost more, and you’ll need a bigger mortgage. This largely depends on location, and how much you have to put towards the deposit.

Naturally, if you’re downsizing, the cost will usually be less, and you’ll need a smaller mortgage – unless you’re able to buy your new property outright and don’t need a mortgage at all.

Changes in monthly mortgage repayments

Your monthly mortgage repayments are likely to be more if you upsize and less if you downsize. By how much depends on your current property and new property, plus any additional funds you’re putting towards the deposit.

Interest rates, loan terms and equity can also affect the difference in monthly cost.

Interest rates and mortgage loan terms

Finding the deal that’s most suitable for you – the type of mortgage, its term (length) and interest rate – is wise. A mortgage is one of the biggest financial commitments most of us make, so it’s important to be prudent. The deal you secure is likely to have a big influence on your financial standing for quite some time. Compare mortgage deals or talk to a broker who understands, and has access to, the whole market.

Be mindful of mortgage affordability. It’s about being able to afford your monthly repayments comfortably, along with any other financial commitments you may have.

Equity considerations

As touched upon already, if you’re downsizing your home, the equity from your current property could cover the cost of your new home or help keep your new mortgage small.

Though, if you’re upgrading to a bigger home, you might need to add additional funds to your deposit, even after using equity from your current home.

Costs involved in upgrading or downsizing

Whether you are upgrading or downsizing, you’ll need to factor in closing and moving costs – including potential early redemption mortgage charges, exit fees, valuation fees, stamp duty, estate agency and legal fees – and any anticipated renovations, even additional furniture.

Larger properties will generally bring higher council tax, insurance premiums, maintenance, repairs and utility bills.

While smaller properties typically cost less to run, renovate, repair and insure.

Mortgage portability vs new mortgage

Porting your mortgage simply means purchasing a new home but staying on your existing deal or rate. Note it’s not the loan itself which is ported.

You’ll need to reapply. First, check whether porting’s an option for you. If so, it can make things a little easier with less research and paperwork needed. Your lender will already hold a lot of your relevant information.

Changes in circumstance - including your home’s loan to value (LTV), lending criteria and your income and finances – could affect the outcome. If your mortgage isn’t agreed, go down the new mortgage path.

If you’re considering upgrading or downsizing, it will pay to compare all available mortgage options. An experienced mortgage broker will almost certainly have come across similar situations previously, so they’ll have an idea of the best routes you can take from the outset.
