Before buying a home, people need a homeowner's license. To get this, you must show you have a basic set of tools (inspected every two years to make sure you haven't done something like lose the screwdrivers by using them as garden stakes), and demonstrate basic homeowner's skills, like resetting a breaker, fixing a toilet flapper valve, cleaning the dryer outlet, and so on. Retested every five years, and must show an added new skill at each retest. Well, that's how it should be.
