Ever wondered just how much your fellow commuters are paying for their monthly mortgages? Now, a new study has identified the London tube lines with the most expensive monthly payments. As ever, it’s mind the mortgage gap as the Waterloo and City line has been named the most expensive for homeowners on the underground network with an average payment of £5,632 per month.

It’s little surprise considering that this line – colloquially known as ‘The Drain’ – has just two stops on it: Waterloo and Bank. Both are in zone 1, and the journey between them typically takes around four minutes, a fact which has seen disgruntled Redditors give it the title of ‘useless.’.

So, if there are only two stations, why was it built? In the late 1800s, a survey found that 12,000 per day needed to get from Waterloo to the City (and back home again, as many commuted in from Surrey and the surrounding home counties). And so, in 1894 work began on this short but sweet tube line – and it received its royal opening by Prince George, the Duke of Cambridge, in 1898.
History aside, data from estate agent Foxtons shows that in Waterloo, the average property price is £925,714 – and some even shoot up to £2,350,000. And so, it’s little surprise that this line is so dear in the mortgage world. It’s not much better in Bank, the financial heart of the city, where properties typically cost £825,000 – a whopping £527,834 over value of the average UK home, projected at £297,166 as per Halifax’s House Price Index for December 2024.
