Why a 35 year mortgage could cost you £57,000 more

I was recently paying in a cheque (remember them) at an HSBC branch in affluent High Street Kensington and I couldn’t help but read the advert dotted above most of the machines.

‘More time to build that Swedish flat-pack’ read the headline and underneath, ‘with an HSBC 35-year extended term mortgage you could lower your monthly payments and take all the time you need to make it homely.’

In the small(ish) print a few lines down, it adds: ‘a longer term means more interest is payable overall.’

Advertising drive: HSBC Kensington was dotted with these adverts above the machines – it is well worth crunching your own sums independently when buying

This small print could be worth £57,500 to the lender. 

Why? Well, crunching the sums, if you borrowed £400,000 at 2.44 per cent –  a not unlikely scenario in Kensington – you’d pay back £595,203 over 35 years, if the mortgage rate remained constant.

Borrow a mortgage over 30 years, a now commonplace term, and the total cost would be £564,492.

But take out a mortgage over 25 years – the traditional length of a term, which has fallen out of favour thanks to surging property prices – and the bill would be £534,721.

That is a significant difference. Yes, monthly payments are £1,417 versus £1,568 for 35 years against 30 years, but that interest should make you seriously consider whether you can tighten your belt and pay an extra £150 per month.

The problem is that longer term mortgages are used as a way of getting borrowers to meet affordability tests based on monthly payments 

I’ve picked £400,000 as the sum to borrow as I was near This is Money HQ in Kensington and it is the maximum amount someone can borrow on a 10 per cent loan-to-value with the high street giant.

That said, you wouldn’t get much in the W8 postcode for below half a million quid. 

Meanwhile, 2.44 per cent is the best rate on offer from HSBC with a five-year fix with the same LTV.

Even if you downgrade the amount borrowed to a more normal sum, for example £150,000, the cost of having a 35-year mortgage rather than a 30 or 25 year one is significantly higher.

In the unlikely event that you could get a steady rate of 2.44 per cent over the lifetime of the loan, the 35-year mortgage will cost £216,539 to pay back, while the 25-year one will cost £196,036. That’s a difference of £20,500.

I’m not picking on HSBC here. The bank is offering an increased term and it is up to homebuyers to decide whether it is worth an extra five years’ worth of interest.

Furthermore, first-time buyer friends who have recently had an offer accepted on a home, tell me they have a mortgage-in-principle for beyond this term from a rival provider.

Around half of mortgage lenders are now said to offer 40-year mortgage terms – and if you added that to my example above, you’d be talking about £626,835 total payable, with a monthly outlay of £1,306.

They say they were recommended the product from the lender – which I will not name as it was confidential conversation – and that worries me.

Additionally, they told me they could overpay the mortgage by 10 per cent per year, which is fairly commonplace.

However, if that is the case and they have the means to do so, it probably makes more sense to go with a shorter mortgage term.

Many become so blindsided by the need to get on the property ladder, they may not be taking their time to look at the boring stuff, the stuff that can lump thousands of pounds of interest onto a property loan.

Instead, they be having their heads turned by the fact a lower monthly payment is good for their bank balance in the short-term.

I’m not saying a 35-year mortgage term may not fit for some buyers, either. 

The term is not set in stone and can be changed when you remortgage.  

But it’s food for thought after probably spending years cobbling together a deposit, that those who may not understand the full ins and outs of a mortgage, could be stung with a longer than needed term simply by not understanding how a property loan works.

And it is not entirely their fault. There was a distinct lack of financial education at school and many do not like talking about money, so are happy to swallow advice from staff at financial providers.

My £57,500 example above would be enough to buy more than a thousand Billy bookcases from Ikea, the Swedish furniture giant’s best seller. 

Although, I do not recommend building more than one item of flatpack furniture a month for your own well being.
