If the SWG book is correct, houses, extractors and other items that have a deed can be deconstructed. First make sure that you have fully paid the maintenance on the structure or that you click yes when it asks if you would like to make the required maintenance payment. If not, your item goes poof! Then click on destroy, then reconfirm, and the deed should show up in your inventory. I wasn't able to find any info on what happens to the items (like a couch inside of a house) when the deed is placed in your inventory. My guess would be that those also return to your inventory and you have to replace them once you replace your house.
Looks like if we don't like the neighbors we can move on!
