Extend Driveway for house hack

[Sean Link]

Still looking for my first house hack. One variable that has been problematic when searching for properties is the amount of parking available. Has anyone ran into this issue? Did anyone decide to increase the size of the driveway? If you did, what material did you decide to go with and would you do it again? I am considering gravel because it is cheap but thought it might be smart to ask in case there are other variables that I am not considering.
