I've barely started and I already hate house hunting. Then, once you have finally found a reasonable/good place, you then have to move which (especially with all my stuff - for those that have never been to my house, I have a lot. No really, I mean A LOT. I can't stress how much junk I have enough. Think of ALOT and then multiply it by SOME MORE. Now you're getting close. Yeah, I know, I need to get rid of some of it. Why do you think I've been putting things up on ebay all week?).
Everything is also so expensive and so small.
London rents are verging on the ridiculous. We're looking at £1400 a month for a 3 bedroom house (that's about $2,800 for you New Worlders) and it's still a struggle finding somewhere! If we lived in Notting or Leicester we'd be able to find a 3-bed place for between £500-600 a month! Even Brighton would be between £900-£1000 a month.
I love London, but the city is doing it's damndest to get me to relocate.
