Research by mortgage adviser Alexander Hall show just how much buyers pay for a mortgage on homes close to different London tube stops. 

The firm analysed the current cost of a mortgage across every station on the London Underground, including the Elizabeth Line and DLR, looking at the monthly repayment for an average house price in each station postcode, minus a 15% deposit, and based a two year fixed rate mortgage with a loan to value of 85% and a rate of 4.77%.

High Street Kensington is home to the highest monthly mortgage payment at £9,890 per month. Heathrow is the most affordable with an average monthly payment of just £1,316.

At an average of £5,632 per month, the Waterloo and City line tops the table when it comes to the highest average monthly mortgage payment across all network lines.

The Circle line comes in second, with the average cost of a mortgage across the line costing £5,323 per month. The Victoria line is the third most expensive with a mortgage costing an average of £4,027 per month, with the Northern (£3,894) and District (£3,891) lines also amongst the most expensive for a mortgage.

The DLR ranks as the most affordable with an average monthly mortgage cost of £2,610 per month, just beating the Elizabeth line (£2,620).

When it comes to the line with the largest mortgage market gap between the most and least affordable station, the District line tops the table. There’s a difference of £8,248 per month between the average monthly mortgage payment in High Street Kensington (£9,890) and Upney (£1,642).

The Piccadilly line and the Elizabeth line are home to the second largest mortgage gap. The average monthly cost of a mortgage in both Piccadilly Circus and Tottenham Court Road (£8,496) comes in some £7,181 higher than Heathrow (£1,316).

Across the Hammersmith and City line, a property around Great Portland Street will set you back £6,854 more per month for the average mortgage versus buying in Barking.

An Alexander Hall spokesperson says: “One weapon in the arsenal of London homebuyers is the capital’s outstanding transport links and the London Underground, in particular.

“As our research shows, you can dramatically reduce the cost of your mortgage by looking further along the tube line that runs through your ideal destination. Whilst you may not want to adjust your expectations from High Street Kensington to Barking, you may well find that even a stop or two can help to cut the cost required to climb the London ladder.”
