Round this way, in the cheapest area, a small one bed flat is at least £130,000.
So if the average wage is £25,000 and you can borrow 3 1/2 x your salary, this is about £90,000.
This leaves you to find about £50,000 cash to buy the flat and pay fees and buy some second hand furniture and some cheap appliances.
Takes a bit of saving living with your parents and very difficult if you are renting a room, which round here is about £120 a week.
