letter to council asking to buy some of their land

[cocoa123]

I have been trying to source piece of land/site/back or side garden for infill self build house in my area for years without a success. Now I’m thinking to access local authorities to see if they have some land available for sale as but no not know how to wright the inquiry. Can you, guys, help me with the inquiry template? Thanks in advance.
