hi i am buying a 2 bed 1940's bungalow which needs lots of work,however i have just had the survey carried out and been informed it is not of traditional build and has concrete walls,i have been told i should be ok with my mortgage as i am with the halifax which is one of a few lenders that lend to non traditional build,but am concerned just how much it will affect the resale value once i have improved the dwelling.If anyone has any information on this it would be greatfully received.
