I am looking for a house to do up and sell on for profit but not to live in. One of dh's clients lives next door to a house which is perfect for us and to cap it all the owners have done a bunk. So, having done a search at HM Land Registry to obtain details of the mortgage company and other title information (they have owned it since 1977) I approached the mortgage company who cannot say whether it will be repossessed. The title information also gives a c/o address for when they purchased the property. Having searched the details of that property I find that there is still someone living there by the same surname (possibly mother?). Would it be immoral to write to that address to enquire about their wish to sell the property privately?
