So just want some advice from you money savvy mumsnetters!
Long story short.
We have a mortgage of 146k live in London so pretty low, house valued at £450 this month ( only been here two years so house has doubled in value)
We have debts of around £15k on 0% cards/catalogues
for now...
My question is, we would like to borrow against the house to extend the property next year, perhaps take out £60k ish. Would you recommend borrowing £75k now and pay off debts and leave money for extension in the bank till we are ready or should we keep putting all our excess money into paying the debts before remortgaging?
Trouble is now, I'm loosing sleep with the debt taking up nearly all our spare cash a month and would feel so much happier knowing they've been paid and we could then actually over pay the mortgage quicker as we could have borrowed the money a year earlier if that makes sense? Sorry for the ramble but it's driving me mad and a bank won't give me such advise!
It's making me feel so anxious as I'm worrying of we apply now they'll think we have problems as we did borrow £15k last year to pay off a really stupid car loan we had 
Thanks for any relies!
