It's a house. The yearly rent is £15.00. The reason I wish to buy is that I would like to build a garage and would need permission off the ground rent owner. I believe that if I were to build, the "agent/surveyor" could increase the rent and could keep increasing it every 3 years. £15.00 a year then suddenly becomes a good investment for them.
Thanks for the info-looks like it's going to be a long night
