1. neighborhoods to rent a flat in. I'm looking for a place that is not too expensive; where the neighbors keep to them selves, but one in which the client will find appealing (as in not too dodgy or inconvenient to get to). Earl's Court is one of my favorite spots in London.
I still wouldn't work from home, but Earl's Court passes those tests and has a significant sex work scene. It's not cheap though - if you live there you get letters from estate / letting agents on a daily basis telling you how much you could rent the place for.
2. could we go over the landlord / tenant issue again; the landlord is not responsible for my activities; however, i would be responsible for any activity that took place if i were to sublet the flat (which i do not intend on doing). Is that correct?
Basically. If they know what you're doing, they'll either throw you out or charge you much more.
If you did sublet, the place becomes a brothel, and that's illegal for you (to control) and them (to allow). If they don't own the place themselves, they're also committing an offence if they knowingly let you use the place for 'habitual prostitution', another reason for making sure they don't find out.
3 if i hire a security guy, he is not liable for anything, e.g. can't be accused of being a pimp? yes?
What's illegal is 'control for gain'. He can gain for your work (i.e. you can pay him) but he cannot do anything like tell you who to see, what to charge, what to do etc etc. Obviously, that's not going to be the case but if you piss off the neighbours and the police take an interest in you and he's done things like answer the phone and chat with potential clients while you're busy, he's still likely to be ok, but they're going to start asking questions.
4. i read some info on punternet about walkups. are these worth it or a waste of time?
The people I know who've worked in one are mixed. You can make money, but it's by having a very large number of clients: if you look at the reviews on PN, you'll see the price in a Soho walkup tends to be low. They're not cheap to rent either and if you don't get the volume, it's quite possible to leave with less than the maid, despite having half a dozen or more clients.
When I first started, the internet was just beginning to take off; and so the isolation was tremendous; almost no websites providing this sort of info.
Yep. It's amazing how much difference the net, mobiles (US: cell phones, Germany: handy phones) etc have made.
