Mortgages: As a First Time Buyer, What Should I Do ?

mortgages

I know small of the banking logic and even less about mortgages. I am in the scarey property market place for the first time. I rang up a mortgage lender and they sent me a ‘Key facts illustration’ I rang them 3 days after receiving it to apply for a mortgage and they told me that that particular mortgage (10 year fixed) had been withdrwn two days ago.

Whats going on at the moment and what should I do ?
