If you’re looking into second home mortgages and are wondering how much you can afford first, it makes sense to research and start your budgeting with our specialist calculators.

While they can’t replace a fully-informed broker having access to very specific likely cost scenarios, they are useful to get those all-important initial estimate figures to get you started on your mortgage application.

Here we provide more information on how much you might be able to borrow for your ideal second home.

How much can you borrow for a second home?

This will depend on your income and financial circumstances as a whole. Of the lenders out there who are willing to offer mortgages on second homes, the majority are far more focussed on how well you are able to afford the loan, rather than caps on how much.

So, while they’ll still work out affordability on salary multiples – usually about 4.5x times or 5 times your annual salary – the deal breaker will always be whether you can comfortably afford repayments on both a first and second mortgage, which you will have to prove in your application. Some will even stretch to 6x income multiple for attractive borrowers. For example, HSBC stipulates that loans will be considered ‘if both loans can be serviced entirely from an applicant’s salary, subject to normal credit assessments’.

Calculate your maximum borrowing

You can get a better idea of how much you might be able to afford with a second home mortgage in our calculator, but please note, this is for guidance only. A broker who specialises in second home mortgages, like the ones we work with, can help you to determine figures more precisely.

Mortgage Affordability Calculator

Use this calculator to determine how much you could potentially borrow for a mortgage, based on the typical salary multiples used by most UK lenders.

Most lenders would consider letting you borrow

This is based on 4.5 times your household income, the standard calculation used by the majority of mortgage providers. To borrow more than this, you will need to use a mortgage broker to access specialist lenders.

Some lenders would consider letting you borrow

This is based on 5 times your household income, a salary multiple you might struggle to qualify for without the help of a broker. This income multiple is not widely available to customers who are applying directly with a lender.

A minority of lenders would consider letting you borrow

This is based on 6 times your household income, a salary multiple you will struggle to get without a broker. Six-times salary mortgages are usually only available under very specific circumstances.

It’s also worth bearing in mind that your existing mortgage commitments will also be factored into the lender’s affordability assessment. If the repayments and other fixed expenses on your primary residence are high, this could reduce the amount you’re able to borrow.

Other borrowing conditions

All lenders are different and implement their own framework when it comes to granting loans. There are some who will have further restrictions for second mortgages in order to mitigate risk, such as Newbury Building Society, which insists that the second property’s price does not exceed the first. Stafford Railway Building Society will only lend to people with a minimum income of £40,000, and Harpenden Building Society has a minimum loan cap of £75,000 and a maximum of £2m.

How much deposit you will need

The majority of willing lenders are willing to provide a loan-to-value (LTV) ratio of 75%, requiring a 25% deposit from the borrower for a sale to be feasible. The likes of Virgin Money and Halifax have previously said this is based on whether the customer is able to afford all credit commitments, including any other mortgage you might have.

You can read more about deposit requirements in our guide to second home mortgages.

How a broker can help you navigate the second mortgage market

As we are exploring here, there are no hard and fast rules when looking for a second mortgage, so understanding exactly how much you can afford and what deals are available to you is almost impossible to ascertain at the planning stages.

Finding an experienced broker in this field should be the first step you take in this process because they have advanced knowledge and access to a marketplace that is constantly fluctuating and involves many variations of lender practices.

We're so confident in our service, we guarantee it.

What if you’re releasing equity to buy a second home?

If the sums add up so that you have enough equity in your first home to put towards a second, releasing it to finance this move might be possible. Again, it will all come down to convincing a lender that you are able to afford both loans without a struggle.

Some lenders may want to know how you intend to use the second property in order to sanction this move, with popular scenarios being investing in a buy-to-let or commercial property, or buying a holiday home. See our guide to remortgaging to buy another property for more information.
