People get interest-only mortgages for lower initial payments, freeing up cash for investments or other expenses, often when expecting higher income later or planning to sell/refinance before principal payments begin. Benefits include increased short-term cash flow, affording more expensive properties, and flexibility, but they risk higher payments later and no equity build-up during the interest-only phase, requiring a solid repayment plan like refinancing or selling.
