An interest-only DSCR loan lets you pay only interest for the first several years, often 10. Your payment drops, cash flow improves, and because many lenders qualify on the lower payment, your DSCR goes up too.
The Math
| $400,000 loan at 7% | 30-yr amortizing | Interest-only |
|---|---|---|
| Principal & interest | About $2,661 | About $2,333 |
| Taxes, insurance, HOA | $650 | $650 |
| Full payment (PITIA) | About $3,311 | About $2,983 |
| DSCR at $3,200 rent | 0.97x | 1.07x |
Same property, same rent. The interest-only payment moves it from below 1.0x to above it.
Advantages
- Qualifies tighter deals without a no-ratio program
- Higher monthly cash flow for reserves, repairs, or the next purchase
- Flexibility: you can usually pay extra principal when you want
Tradeoffs
- Higher rate: interest-only usually adds to pricing
- No principal paydown: equity comes only from appreciation or extra payments
- Payment jump: when the interest-only period ends, the loan amortizes over the remaining years, so the payment rises more than it would on a standard 30-year schedule
Who It Fits
Investors focused on cash flow, those planning to sell or refinance within the interest-only period, and properties just below 1.0x. It's a weaker fit if you want to pay the property off or can't absorb the later payment increase.

Interest-Only DSCR FAQ
How long is the interest-only period?
Usually 5 or 10 years, followed by a fully amortizing payment over the rest of a 30- or 40-year term.
Does interest-only increase my DSCR?
Often, yes. Many lenders use the interest-only payment to calculate DSCR, which is lower than an amortizing payment.
Do interest-only loans cost more?
Usually slightly. Interest-only typically adds to the rate.
