London is EXPENSIVE Decent 2 bedroom flat, average not palatial is maybe £1000 a month? Then theres your council tax, then your bills, maybe a service charge, food, transport.................£££££££££££££££££££££££ However, heres what I would personally do, secrete myself in the back of a lorry in calaise, clothe myself in Matalan garbs, pretend not to speak a word of english apart from "Asylum". I guarantee then your going to find the streets of london are indeed paved with gold
