My wife and I have had a response from a letter we sent out asking people if they would consider selling us part of their garden for a new build. We went to view the plot today and it is lovely. We would like to get the plot valued in order to know if it would be in our price range or not. What is the best way to get a valuation on a plot? We know that a mortgage lender would have to send a valuer to a plot before lending us money (we need to get a mortgage for the combined cost of the plot and the build) on the plot. Is there someone we could use in the mean time?
