Living outside London is definitely cheaper. Apparently, the further away, the smaller house prices are. Here’s the math:
60 minutes to the city = minus £480,000 off the property price
40 minutes to the city = minus $372,255 off the property price
20 minutes to the city = minus £299,328 off the property price
So choose how much time you are willing to spend on the road and make your savings budget!
