6 months rent is over £4000 which I'd rather put into a mortgage.
That's only a month's wage for you though. Peanuts.
Also, just rent somewhere crap for six months, not somewhere decent. As in a couple of hundred quid a month, not £600.
It's certainly not peanuts. And I have a child and a wife, we need a house and you can't rent a house for much less than £750 PCM.
Anyway, Sarnie might be able to actually help.
