For a major expensive home renovation (e.g. addition, finished basement, or new kitchen) should one pay cash or finance with a loan? Would such a loan be “good” debt?
The crucial question not addressed by other answers is your ability to repay the debt.   Borrowing is always about leverage, and leverage is always about risk.  In the home improvement loan case, default comes with dire consequences-- to extinguish the debt you might have to sell your home. With a stable job, reliable income, and sufficient cash flow (and, of course, comfort that the project will yield benefits you're happy to pay for), then the clear answer is, go ahead and borrow. But if you work in a highly cyclical industry, have very little cash saved, or for whatever other reason are uncertain about your future ability to pay, then don't borrow.  Save until you are more comfortable you can handle the loan.  That doesn't necessarily mean save ALL the money; just save enough that you are highly confident in your ability to pay whatever you borrow.
