[@mnkee] That is actually going to depend on something I meant to ask you before and totally forgot about. His residence is listed near the London Docks. Now the official London Docks are far to the eastside of London. Yet there are other "docks" in London, some of which are between Westminster Bridge and Blackfiars Bridge. Now the housing over near the official London Docks wouldn't be "estate" like, but run down, poor side of town. Where between the two bridges it would be much higher since it is so close to the Palace, Westminster Abby, and so forth. 

So if you are wanting him down by the actual London Docks, yes, he could walk but it will take till this evening in RP >.> Now if you want him to have his housing near a "Dock in London" closer to the Strand, we can do that and just assume that I meant by foot instead of by horse back with the time frame.
