The option is labeled something like 'destroy structure' (or something similar I'm away from game). It is the top option on the options menu.

If you have enough mantinenace in the harvester then it will NOT destroy the deed. When you first issue the command it will display how much money you have and if it is enough then it will be in green but if it isn't enough it will be in red. Then if you proceed by saying OK or YES or whatever then it will prompt you to enter a 6 digit number just to make sure you're not selecting the option accidentally.
