Land and property not good because you can not take it with you or move from another place to another in some case the car would be even better asset to have.
I like land because of freedom it provides. You can build shelter over it, grow food on it, if you want to move from one place to another — you can always sell it.
land is not freedom
a. property taxes/ maintenance costs means its an ongoing costs
b. your not free to build anything, you need permits to do anything these days, the only thing you dont need permits for these days is to paint the internal walls. but things externally like building extensions, groundwork, even external paint usually needs permission from state or a HOA
c. if you wanted to change the purpose from agricultural to residential you need permit. or the opposite way round
d. as for selling it, thats not a guarantee. land can lay unsold for months/years or become valueless if the area becomes a ghosttown
