LTV Question

Hi,

I purchased my new home in December 2012, purchase price 212k, valuation carried out in August 2012, which gave me a 21% LTV.

My main part of Mortgage currently on a 2yr fixed rate expires end of April 2013, question I have, is how long is the 21% LTV valid for, as I believe the LTV to be at 25% as I purchased the house cheap (due to my position at that time, no chain).

Trying to renew mortgae on line, but offers are limited due to the 21% LTV from last August.

Thanks

Dave
