Interest-Only Loan
An interest-only loan requires the borrower to pay only interest (not principal) during a specified period — commonly the full term of a bridge loan, or the initial years of a permanent loan.
What it means
Interest-only (IO) payments are typical in bridge financing and in the initial years of permanent loans. IO reduces monthly cash outlay and preserves capital for property improvements, but does not reduce principal balance. At the end of the IO period, payments either shift to amortizing (increasing monthly payment) or a balloon comes due.
IO loans are riskier than amortizing loans because the borrower has no principal paydown cushion. In rising-rate environments, IO loans often fail to refinance at previously assumed rates.
