Just FYI, if you own a house, you are by no means obligated to DIY home improvement projects; you can, indeed, just call a plumber and “run away”. And such service is by no means free when you rent; it is totally bundled as part of your monthly rent payment.
And while selling a home for more than you paid is hardly guaranteed, buying a home is unique in that it’s an asset you live in. (In financial terms, this is called “imputed rent”… while even with that, it’s not a sure thing, it does swing the pendulum in favor of buying vs. renting, all else being equal. In the end, it comes down to Return vs. Risk, like all investments do.)
