Buying a building with two flats, can I rent one out and still get a residential mortgage?
NO Even worse, most BTL(buy to let) lenders will not lend if you are going to be living in the property.    There are very few lenders that will touch something like this.    It is likely you will also need to use bridging for the time the building work takes at something like 1.5% per month!
