How are you meant to save any substantial amount of money (i.e. the 20k required for a deposit) when you are spending £800 on rent a month, try renting a single flat anywhere in Brighton for less that £750 a month, it is not possible. Then for most of Brighton you can stick £70 CT a month of top...
No its okay you rent out the tiny one bed flat for £850/month and cream it off to pay your mortgage. That is a cool and good thing to do well done you.
As somebody who is early 30s has a solid professional career and cannot imagine buying a house without a bunse from somewhere (which coming from a working class family is not going to happen) very valuable.
