Green rows hit the 1.25 DSCR threshold for best pricing. Yellow rows qualify for broad lender access. Below 1.0 you still have options — but LTV caps tighten and rate add-ons apply.

Why rate scenarios matter for DSCR deals
DSCR lenders use your interest rate to calculate P&I, which is the largest component of PITIA. A half-point rate difference on a $300,000 loan is roughly $100/month — enough to move DSCR by 0.05–0.08 points depending on your rent and fixed costs. On a deal where you're targeting 1.25 DSCR, that swing is the difference between best-pricing and a rate add-on.
The rate scenarios table shows you, at a glance, whether your deal has cushion. If every rate from 6% to 8.5% produces a 1.25+ DSCR, you can be selective about timing. If only the 6% row clears 1.25 and today's market is at 7.5%, you know you need to adjust your strategy before locking.
The two DSCR thresholds that matter most
Most DSCR lenders use two key thresholds in their pricing matrix:
- 1.25+: Best pricing. Full LTV access. Widest lender pool. No DSCR add-on to rate.
- 1.00–1.24: Mainstream pricing. Broad lender access. LTV up to 80% for strong credit. No or minimal rate add-on.
Below 1.00, you start to see material rate add-ons (typically +0.25 to +0.50%) and LTV caps that tighten to 70–75%. The rate scenarios table color-codes each row to show you which tier each rate produces.
How much does each 0.5% rate move affect DSCR?
On a 30-year $300,000 loan with $2,800/month rent, the approximate DSCR impact per 0.5% rate move:
| Rate | P&I | DSCR (at $700/mo TIHA) |
|---|---|---|
| 6.0% | $1,799 | 1.12 |
| 6.5% | $1,896 | 1.07 |
| 7.0% | $1,996 | 1.03 |
| 7.5% | $2,097 | 0.99 |
| 8.0% | $2,202 | 0.95 |
| 8.5% | $2,308 | 0.91 |
TIHA (taxes + insurance + HOA) assumed at $700/month in this example. Each 0.5% rate increase costs roughly 0.04–0.05 DSCR points on a deal with $2,800/mo rent.
How to use the rate scenario table
- Start with your actual deal numbers. Use the loan amount you plan to borrow, the actual current monthly rent (or market rent from a comparable), and your best estimate of tax and insurance.
- Identify the break-even rate. Find the lowest rate where your DSCR drops below 1.25, then below 1.00. These are your pricing inflection points.
- Check today's market rate. Is it above or below your 1.25 threshold rate? If above, consider whether you can bring the deal to 1.25 via more down payment, I/O structure, or lower purchase price.
- Build in a buffer. Rates between quote and close can move 0.125–0.25%. Run the scenario at today's market rate + 0.25% to see if your DSCR tier holds even in a modest rate rise.

Frequently asked questions
Why does rate matter so much for DSCR?
On a $300,000 DSCR loan, the difference between a 6.5% and 8.5% rate is roughly $366/month in P&I. If monthly rent is $2,800, that payment difference moves DSCR from 1.31 to 1.02 — from the best pricing tier to just above the break-even tier. A single rate point costs you about 0.15 DSCR points on a typical deal. This is why rate-shopping across multiple DSCR lenders is so important.
What rate should I use for DSCR underwriting?
Use the actual rate from the lender's quote — not a guess or a national average. Rates vary 0.375–0.75% across DSCR lenders on the same deal. For projections before you have a quote, use a conservative assumption (current market rate + 0.25%) so your DSCR doesn't look better on paper than it will at closing.
What DSCR do I need to get the best rate?
A DSCR of 1.25 or higher unlocks the best available rate across most DSCR lenders. Below 1.25 you start to see rate add-ons (LLPAs). Below 1.00 you're looking at add-ons of 0.25–0.50% on top of base rate. Below 0.75 you're in a specialty sub-tier with the most restrictive pricing. The rate scenarios table shows you exactly which rate still clears 1.25 for your deal.
At what rate does my deal stop qualifying?
There's no hard stop — DSCR lenders will fund deals at almost any DSCR above about 0.60 (some lower), but the LTV and rate get worse as DSCR falls. The practical threshold most investors care about is 1.00: below that, most lenders cap LTV at 70–75% and add rate pricing. The table highlights which rates clear both the 1.00 and 1.25 thresholds for your specific deal.
Should I lock a rate when it hits my DSCR threshold?
If the rate produces a DSCR you're comfortable with and your acquisition price and rent assumptions are solid, locking is reasonable. Floating in hopes of a lower rate means deal uncertainty and potential re-underwriting if rates move. Most DSCR investors lock within 45–60 days of expected close when the economics work.
How do taxes and insurance affect which rates qualify?
Taxes and insurance are fixed costs in PITIA — they don't change with rate. But they set your 'floor' — the minimum payment your rent must cover regardless of rate. Higher tax or insurance means fewer rates clear 1.25. On high-tax states like NJ (2.49% effective rate) or IL (2.27%), the tax component alone can push DSCR well below 1.0 even at favorable rates. Always include actual tax and insurance in the calculator.
What does it mean when only one or two rates hit 1.25?
It means the deal is rate-sensitive — small movements in the rate environment can push you out of the best pricing tier. Strategies to widen the number of qualifying rates: larger down payment (reduces P&I directly), interest-only structure (cuts monthly payment 10–14%), or identifying undervalued rents that could support a higher rent at lease renewal. The rate scenarios table quantifies exactly how much rate headroom you have.
Can I use a rate scenario analysis during the offer stage?
Yes, and you should. Before making an offer, run the rate scenarios at your anticipated purchase price and down payment. If only the lowest available rates clear your target DSCR, you have limited margin for error. If multiple rate scenarios produce a 1.25+ DSCR, the deal has a wider safety margin for rate volatility during the purchase process.
