Having owned land is a blessing. It has lots of potential; however, the term you may be looking for is that it is an illiquid asset. Meaning, it has value, but not easy to sell and convert to cash. If cash is needed, the fastest way to sell it is to lower the price (discount). There will always be a buyer at a certain price.

As you pointed out, owning land can also be a burden due to taxes. But this is a good problem to have! I think the best way to turn this around is to find ways to make it productive. Find a farmer partner who can help till the land. It definitely is not easy, but that is how the economy can grow. Doesn't necessarily mean you'll get rich by it, but at least your assets are productive. :)

The land might not be convenient now, but it is a finite resource. Population grows, the cities will never be enough. During the pandemic, a lot of people moved out of the cities and went home to their hometowns, especially those who are able to work in a remote setup. Land values can rise up immediately as soon as development within the area starts. Timing though really depends, can be soon, or can be 30 years from now.
