I think a lot of people are scared of buying "unimproved land". The question is whether you can, or are willing to spend your time making improvements, and whether the money you put in will equal an increase in the eventual selling price.
If you can do the "start a food forest from seeds" technique, the money cost is negligible and the time cost not unmanageable. If the property doesn't sell, you will still end up with a source of food that involves driving out there on likely harvest days, and bringing back organic nuts and fruit to use yourself or sell to cover your carrying costs.
If you're prepared to spend more money, and willing to pull a bit of a fast one, I know of someone who pulled house plans "off the shelf" and then told the planners that he needed to build the garage first so he'd have a work space to build from. The "garage" was passive
solar oriented with an attached
greenhouse space and ~20x20 ft. The fellow moved into the garage and simply never built the "house" part that was supposed to go with it. With the kind of storms North America's been getting, build this thing tough but basic and definitely totally fire resistant. The community brass are probably just as aware as you are about the current housing situation, so if you say you're "trying to sell", they will likely let things slide for some time before actually threatening you. If I was doing this, I'd actually make sure the garage included an
underground cold cellar so you have a place to store some of those goodies from the food forest when it starts producing. A solid little outbuilding could easily be the selling feature that could make the difference in finding a buyer.
Good luck with however you decide to approach this problem.
