Is it possible to make money by getting a mortgage?
I think this is possible under very special conditions.  The important part of the description here is probably retired and rich.  The answers so far apply to people with "normal" incomes - both in the sense of "not rich" and in the sense of "earned income." If you sit at the top tax bracket and get most of your income through things like dividends, then you might be able to win multiple ways with the strategy described.  First you get the tax deduction on the mortgage interest, which everyone has properly noted is not by itself a winning game - You spend more than you save.   BUT... There are other factors, especially for the rich and those whose income is mostly passive: I'm not motivated enough on the hypothetical situation to come up with a detailed example, but I think it's possible that this could work out.  In any case, the current answers using "normal sized" incomes and middle tax brackets don't necessarily give the insight that you might hope if the tax payer really is unusually wealthy and retired.
