Doesn't work for major cities an example from the UK 2 bed flat in Bedford a 35/50 min commute is £115,000 red lion square near our office its £625,000.
I've made a point of living biking distance from every job I've had. It's definitely cost me much more in rent than it's saved me in automobile costs because of the astronomical price of living in an urban center (downtown San Francisco and Manhattan, in my case), but for me the financial aspect was dwarfed by quality-of-life preferences (and the good fortune to be in a situation where I could make such a trade-off).
First capital connect is a bit longer (50-55 min) I normally catch 7:30 and am in the office at 8:40.
