If a house cost £200,000 and The average wage is £23,000/annum : how do you need to make so you can afford a house in UK ?
I assume you're asking how much do you need to earn to afford such a house? Well that depends on the lender. I've heard that some are allowing 5 times your annual salary so in that case, £40K per year. Of course, Edinburgh seems rather skewed on the house price vs wage ratio!
The houses around where we are in our specific area are about £200-230K for terraced, £250-350 for semi and £350 upwards for detached. High Wycombe as a whole is skewed lower, probably £150-200+ terraced, £175-300+ semi, £200 upwards for detached. Of course, it all depends on what part of town you're in.
If you're moving to a new town or city you'll just need to do a bit of legwork to familiarize yourself with different parts and what the estate agents are selling in those areas.
