Rate-and-Term Refinance on a DSCR Loan, Explained
A rate-and-term refinance replaces your current DSCR loan with a new one at a different rate or structure, with no cash out — new balance equals payoff plus closing costs. The DSCR is still recalculated on the new PITIA, so a lower rate helps the ratio, but a shorter term or added costs can offset it.

What a rate-and-term refi does and doesn't change
Unlike a cash-out refi, a rate-and-term refinance isn't about pulling equity — the new loan amount is sized to pay off the existing balance plus closing costs, nothing more. The goal is usually a better rate, a different amortization structure, or getting out of a prepayment penalty window that's about to end anyway.
Because the loan amount barely moves, the main driver of a new PITIA is the rate itself. A lower rate on a similar balance produces a lower payment, which raises the DSCR. A move to a shorter amortization — say from a 30-year to a 25-year structure — raises the payment even at a lower rate, which can offset some or all of the ratio gain.
Worked example: rate drop vs. term shortening
Now take that same lower rate but paired with a 20-year amortization instead of 30. The payment can end up close to where it started, because a shorter term forces more principal into each payment. The DSCR gain from the rate drop gets eaten by the term shortening — sometimes entirely.
| Scenario | Rate direction | Term | Payment vs. before | DSCR impact |
|---|---|---|---|---|
| A | Lower | Same (30-yr) | Lower | Improves |
| B | Lower | Shorter (20-yr) | Similar or higher | Flat to worse |
| C | Same | Shorter | Higher | Worse |
When a rate-and-term refi is worth doing
It clears the bar when the new rate materially improves the ratio or removes a structural problem — an expiring interest-only period, a prepayment penalty that's about to convert to a worse one, or a rate that's simply out of step with what the property could get today. It's worth running the numbers on your specific balance rather than assuming any rate improvement automatically helps.

- Get a live quote for the new rate and structure at current DSCR rate assumptions.
- Rebuild PITIA under the new terms — rate, term, and any escrow changes.
- Compare the new ratio to your lender's floor before committing to closing costs.
Key takeaways
- A rate-and-term refi pays off the existing balance with no cash out — the loan amount barely changes.
- A lower rate improves the DSCR only if the amortization structure doesn't offset it.
- Shortening the term while lowering the rate can leave the payment, and the ratio, roughly flat.
- Run the new PITIA before assuming any rate improvement helps your qualification.
