With the central spots of the District line within commutable distance of creative centres such as Old Street and Shoreditch, this line as a whole saw an average £152,158 deposit – despite having nine out of the ten most affordable stops in London.
Across all 265 stops analysed by the research, the average deposit stood at £105,898. This means that buyers looking for an average London home would see properties close to Hammersmith station where there was an average deposit of £105,456, or East Putney at £106,136.

“From our research, it’s important to highlight that there are affordable areas to buy in London that remain within a stone’s throw of a tube station.”
