Interest-only vs. amortizing on a rental loan
Should I take an interest-only rental loan instead of a fully amortizing one?
An interest-only period and a fully amortizing schedule produce a different payment on the exact same loan amount and rate. Here is what that difference actually does, month to month and later.
- Interest-only DSCR loan The lower interest-only payment raises the DSCR ratio directly, which is the specific lever a deal sitting close to a lender’s coverage floor often needs.
- Interest-only as a way to avoid a real cash flow problem It lowers the payment during the interest-only period, but the balance does not shrink and the payment resets higher afterward — it defers the problem rather than solving it.

No lender here publishes a rule for this
This is an underwriting judgment, not a published threshold. None of the 37 lenders in the directory states a policy on it, so there is no honest way to build a shortlist — and a list computed only from which products a lender writes would tell you nothing you could act on.
What matters here is how the file is presented rather than which lender receives it. The sections below cover that. When you are ready to approach lenders, the directory shows what each one does publish, with the date it was verified.
What changes in the payment itself
A fully amortizing payment covers interest plus a slice of principal every month, so the balance shrinks over time. An interest-only payment covers interest only during the IO period — the balance stays exactly where it started, and the monthly payment is lower for the same loan amount and rate.
Why investors reach for it
The lower payment does two things: it improves monthly cash flow directly, and because DSCR is rent divided by payment, it also raises the coverage ratio itself. That second effect matters most for a deal that is close to a lender’s minimum DSCR — an interest-only structure can be the difference between clearing the floor and not, for a property whose rent has not moved.
What it costs later
No principal paydown during the IO period means more balance remains outstanding whenever you sell, refinance, or reach the end of the IO term. If the loan reverts to a fully amortizing schedule after the IO period, the payment recalculates upward to pay off the remaining balance over the remaining term — a real payment increase, not a hypothetical one, and worth modeling before it happens rather than after.
What this directory can and can’t confirm
Lender records here do not track which lenders offer an interest-only option or for how long. The roster below is the set of verified rental-DSCR lenders in this directory generally — it is who to ask, not a confirmed interest-only list.
What to have ready
- Your DSCR at the fully amortizing payment versus at an interest-only payment
- How long you plan to hold the property relative to the IO period offered
- What the payment recalculates to once amortization starts

Terms used on this page
- Interest-Only DSCR Loan — An interest-only DSCR loan requires only interest payments for an initial period, typically five to ten years, before converting to fully amortising payments for the remaining term.
- Debt Service Coverage Ratio (DSCR) — DSCR is a property’s gross monthly rent divided by its total monthly mortgage payment. A DSCR of 1.00 means the rent exactly covers the payment; 1.25 means rent exceeds the payment by 25%.
- Net Operating Income (NOI) — Net operating income is a property’s annual income minus its operating expenses, calculated before any mortgage payment. It measures what the property earns, independent of how it was financed.
