Sub-1.0 DSCR

A sub-1.0 DSCR loan is a DSCR loan that qualifies properties with debt service coverage ratios below 1.0 — meaning the property's rental income doesn't fully cover the mortgage payment. Specialty lenders accept these scenarios with stronger borrower profiles in exchange for slightly higher rates.

Standard DSCR programs require a minimum 1.0 ratio (rent equals or exceeds mortgage). When a property doesn't hit that floor, sub-1.0 programs become the fallback before no-ratio DSCR. They're the middle ground.

How sub-1.0 DSCR works

The lender accepts that the property doesn't fully cash flow on paper, but compensates with stricter borrower requirements:

• Minimum DSCR floor: Different programs accept different floors. Common tiers: 0.95, 0.90, 0.85, 0.80, 0.75.
• Higher credit score requirement: Often 700+ minimum vs. 660-680 on standard DSCR.
• Higher reserves: 9-12 months of PITIA in liquid reserves typical.
• Lower LTV: Usually 70-75% maximum vs. 80% on standard DSCR.
• Rate premium: Typically 0.25-0.75% above standard DSCR rates.

The deeper the DSCR drop, the tighter the qualifying box.

When sub-1.0 makes sense

Property cash flows but barely. A DSCR of 0.90 means rental income covers 90% of the mortgage payment. The borrower covers the 10% gap from personal cash flow. That's still profitable when factoring in tax benefits, appreciation, and principal pay-down — but it doesn't qualify under standard 1.0+ DSCR rules.

Strong borrower, weaker property. A high-credit, well-reserved investor wants a property with marginal rent comps. Standard DSCR declines. Sub-1.0 program may approve based on borrower strength offsetting property weakness.

Markets where rent comps don't keep up with appreciation. In rapidly appreciating markets, rent growth lags price growth. A property at $500K with $3,200/month rent might fail standard DSCR with a $375K loan, but sub-1.0 fills the gap.

Bridge to no-ratio. If you can't qualify at 1.0 but don't quite need no-ratio (which has lower LTV caps and higher rates), sub-1.0 splits the difference.

The DSCR ladder

Think of DSCR programs as a tiered ladder:

• 1.25+: Best pricing tier. Property comfortably covers payment.
• 1.0-1.24: Standard program tier. Property covers payment with margin.
• 0.95-0.99: Slight sub-1.0. Property nearly covers, borrower bridges gap.
• 0.85-0.94: Moderate sub-1.0. Stronger borrower requirements.
• 0.75-0.84: Deep sub-1.0. Strict qualifications, rate premium.
• Below 0.75 (most lenders cut off here): No-ratio territory. DSCR not used in qualification. Rate Hero finances down to 0.00 minimum (no rental income required).

The ladder lets you optimize: get the lowest acceptable rate by qualifying at the highest possible tier your scenario supports.

Sub-1.0 vs. No-Ratio

Both programs handle properties that don't hit standard 1.0. Differences:

• Sub-1.0: Still uses DSCR in qualification. Lower DSCR requires stronger borrower profile. Better LTV than no-ratio.
• No-ratio: Doesn't use DSCR at all. Qualifies purely on credit, reserves, and LTV. Lower LTV cap (70-75%), higher rate premium.

If you're at 0.85 DSCR with a strong borrower profile, sub-1.0 is usually the better deal (better LTV, lower rate). If you're at 0.60 DSCR or have no rental history yet, no-ratio is the only path.

Rate Hero's sub-1.0 DSCR program

Rate Hero offers the full DSCR ladder including no-ratio (0.00 minimum) for both purchases and refinances. We don't stop at sub-1.0 floors — qualified borrowers can finance properties at any DSCR level, including deals where the property doesn't generate rental income at all.

The advantage: most lenders cut off at 0.75 minimum, declining everything below. We don't have that floor. Properties at 0.50 DSCR, 0.25 DSCR, or 0.00 DSCR (no rental income at all yet) can still close — qualified on credit, reserves, and LTV instead.

The right tier for your deal depends on the math. A 0.85 DSCR deal closes at standard sub-1.0 pricing — better LTV and rate than no-ratio. A 0.40 DSCR deal closes via no-ratio at the cost of lower LTV and slightly higher rate. We'll show you both options and let you pick the one that maximizes your scenario.
