It now costs as much to buy a home as rent one, thanks to recent falls in mortgage rates.

An analysis by Hamptons, part of the Connells Group, shows the typical mortgage rates of just over 5% for a first-time buyer with a 10% deposit mean the average monthly mortgage payment (£1,328) is slightly cheaper than the average rental payment (£1,356).  

This time two years ago, as interest rates rose, renting became £48 per month cheaper than buying.

In all four regions of the south higher mortgage rates remain a bigger barrier to affordability.  In London, renting has been cheaper than buying since July 2022, when mortgage rates stood at 3.69%.  Today, the average Londoner could save £115 per month by renting.

While further north it typically remains cheaper to buy than rent on a monthly basis, even at much higher interest rates.  In the North East, the monthly cost of renting hasn’t been higher than the cost of buying since July 2011.

This reflects how the same mortgage rate is felt differently across the country.  Generally, the mortgage rate required to equalise the monthly cost of renting and buying tends to be lower across the south of the country than further north.  While Londoners with a 10% deposit require rates of around 4.6% to equalise the cost of renting and buying, further north, it takes mortgage rates of above 6.0% to make buying as expensive as renting (table 2).

The monthly cost of renting vs paying a mortgage with a 10% deposit

However, the agency says that for most of the last 40 years, it’s been cheaper to buy than rent.  In just 36% of the months since January 1987 it has been cheaper to rent than buy. 

Since January 1987, there have only been three occasions when renting has been cheaper than buying for someone purchasing a home with a 10% deposit over a 30-year mortgage term (chart 1).  During these three occasions, it was rising mortgage rates that pushed up the cost of buying rather than rents falling. 

Firstly, in the early 1990s, mortgage rates hit 15%, pushing the average monthly mortgage payment for someone with a 10% deposit up to £649, nearly double the cost of renting at £358.  As interest rates fell, the trend normalised and buying became cheaper throughout the rest of the 1990s and most of the 2000s. 

It wasn’t until around 2007 when banks raised rates on small deposit mortgages that the balance swung back in favour of renting again and remained that way until 2010.  The third instance when renting became cheaper than buying occurred just after the ‘mini budget’ (back in 2022), when mortgage rates rose steeply.

Hamptons says that today, higher mortgage rates that push up the cost of buying relative to renting are a reflection of the extra amount buyers pay in interest.  This is amplified when people buy more expensive homes, such as in the South of England. 

At the typical mortgage rate currently available to a first-time buyer with a 10% deposit (5.11% spread over a 30-year term), it takes 16.5 years for the repayment to outweigh the interest element of their monthly mortgage payment.

However, when interest rates peaked at 6.57% in August 2023, it would have taken an average of 19.5 years for mortgage repayments to outweigh mortgage interest.  This means that 86% of the first payment towards a mortgage taken out in August 2023 went to cover the interest being charged on the loan.  

Back in March 2022 when average rates were just 2.38%, mortgage repayments would have outweighed mortgage interest after just one year, with interest accounting for just 49% of a first-time buyer’s initial mortgage payment.  If mortgage rates remained the same for the whole 30-year term, a person paying the 2.38% rate would pay 69% less in interest (or £206,000 on the average loan) than the person paying the 6.57% rate.
