DSCR is the single most important number in DSCR loan underwriting. The minimum DSCR threshold determines whether the deal funds at all, and the actual DSCR (above the minimum) determines the loan's pricing and leverage.
The standard minimum DSCR thresholds
- 1.25x: most conservative tier, qualifies for the lowest rates and highest LTV (typically 75–80%)
- 1.10x to 1.20x: standard tier on most rate sheets, mid-range pricing
- 1.00x to 1.10x: the entry threshold for most programs, lower LTV (65–70%), higher rate
- 0.75x to 1.00x: "no-ratio" or low-DSCR tier — fewer programs, sub-65% LTV, materially higher rate
- Below 0.75x: rarely fundable as a DSCR loan; the property doesn't service the debt and the lender would be funding a cash-flow shortfall
How the DSCR gets calculated
DSCR = NOI ÷ Annual Debt Service. Sounds simple, but the inputs are where deals slip.
NOI: gross rents (current leases or market rents per appraisal) minus operating expenses (taxes, insurance, HOA, management 6–10%, repairs and maintenance 5–10%, vacancy 3–7%). Lenders often use minimum expense ratios even if the borrower claims lower — they don't want to underwrite an artificially low expense load.
Annual Debt Service: principal + interest on a fully amortizing loan, OR just interest on an interest-only program. Interest-only DSCR is always higher (no principal in the denominator), which is why I/O DSCR loans qualify for higher leverage at the same property cash flow.
How to push your DSCR higher
- Choose interest-only over amortizing: cuts debt service by 30–40%, lifts DSCR proportionally
- Lower the LTV (more borrower equity): smaller loan = smaller payment = higher DSCR
- Choose a longer amortization period (30-year vs 25-year)
- Use a market rent appraisal if current rents are below market — lenders will underwrite to market with proof
- Add a long-term lease in place (typically commercial or BTR) to lock in higher in-place rents
- Refinance after rents increase and 90 days of seasoning
Why lenders care about DSCR above the minimum
A 1.0x DSCR is technically qualifying, but the property has zero cushion. Any vacancy, repair, or expense spike sends the deal underwater. So lenders structure rates to reward cushion: a 1.30x DSCR property pays 50–100 bps less than a 1.05x property at the same LTV, because the lender's downside scenario is much less painful at 1.30x.
For the borrower, the math usually says: stretch for the better DSCR by using interest-only or lower LTV in year 1, then refinance to optimize once rents season.
