Fixed vs. Floating Interest Rates

Which one fits which kind of loan.

A fixed rate stays the same for the entire loan term, giving payment certainty. A floating (variable) rate moves with a market benchmark, usually SOFR, and is common on shorter-term bridge and construction loans.

Fixed vs. floating

A fixed rate stays the same for the whole term, so the borrower always knows the payment. A floating (variable) rate changes with a market benchmark, usually SOFR. Floating rates are common on short-term "bridge" and construction loans, where the lender needs flexibility and the borrower expects to refinance or sell before rates move much. Fixed rates are common on long-term permanent loans, where predictable cash flow matters more.
