nah £300k isn't average, they're in a 7 bedroom house. its a fucking mess and they have about 10 people living there at any one time. the kitchen stinks, is full of fly corpses and has a rat.
i think house prices in the area are about the national average, maybe slightly lower.
i've been looking 2 bed terraces in golden triangle go for between 120 - 140, i'd probably get a 120 one and do it up a bit on the cheap.
GT is a good investment because when you're ready to move you can make quite a bit from renting if you can keep it on. upmystreet.com say the average house price for NR2 is £200k. Tis probably the nicest central area of norwich i know, it votes green and has good primary schools. 3 or so big parks nearby too, the anglians seem to love their green.
east anglia is great, its like a different world with all the freaks and their norfolk ways
