also, i will add, and i don't mean to further put you off - living on your own is lonely, there is a fair amount of crime on the towpaths, moving a boat (depending on weather) (and other boaters - the London contingent of which are especially but unsurprisingly rude compared to elsewhere i've boated (up to Daventry)) on your own can be a true ballache. you would also need to factor in your commute which would change every 2 weeks. join the London Boaters facebook page and lurk for a bit.
