Hi Madam,
I just want to alert you to the fact that you may not qualify for a 100% mortgage, although these have been marketed as new products etc, they may have fairly demanding income criteria. Additionally, as far as I know they will only be offered on certain types of home, eg. 1 bedroom apartments do qualify for some of the lenders. Your best bet is to contact a broker, they will be only too glad to help you, I am sure that someone here can recommend one for you.
