I've always wanted to build my own house and I've found a brilliant piece of land - it's already fenced off from a row of houses and backs onto a little lane. I've been watching it for about a year but the problem is, I don't know who it belongs to and if it's for sale. I've looked in the Land Registry and there's nothing about it there and there's no planning history on the site. No one seems to be doing anything with it other than parking a couple of cars on it.
So, how do I find out who it belongs to and, more importantly, open up a dialogue with them about price without them simply plucking a figure out of the air and doubling it because I seem keen?
