It goes for £2000 a month ($2500) and is in Zone 1, a 25 minute stroll from the London Stock Exchange. You aren't going homeless if you have £2000 a month to spend on rent, and Zone 2 is one stop away on the Jubilee line. You're moving to Zone 2/3, or moving into a flatshare. Or out of London.
Given the location, pricing and finish I suspect it's more likely to be used as a pied a terre -- a second (weekday) home -- for someone in the City.
Some people own more than one house, and perpetually rent those properties out via sites like Airbnb.
So we have:
Buying a property that you don't intend to live in, so that you can rent it out to other people as a short term let.
Buying a property that you live in, and occasionally renting out a spare room as a short-term let while you continue to occupy the property.
These are not the same.
