Does having a loan secured on your home make it difficult to change mortgage lenders?

I bought a house in jan 2006 using a fixed discounted rate mortgage with northern rock which ends in jan 2008.in dec 2006 i got a loan which is secured on my house.in jan 2008 when my discounted rate finishes will i have trouble finding a new mortgage deal due to having the loan secured on the house?
Answer
Naw you should not have a problem, this is done on a daily basis, they call it a refinance. you get another mortgage company to refinance your house and when they do whatever is owed your current mortgage is paid off. the escrow closing agent will take care of all payoffs to your current mortgage. now in order to start this refinance you will need to contact a mortgage broker and complete a loan application, about a month prior to your discount rate expiring. you will find a mortgage broker in your local telephone book. i hope this has been of some use to you, nice luck.
