DSCR loans help real-estate investors qualify based on property cash flow instead of personal income. This guide covers how lenders calculate DSCR, typical requirements, today’s documentation asks, real examples (with math), and the pitfalls to avoid before you sign.

Quick facts

• DSCR (Debt Service Coverage Ratio) = Net Operating Income ÷ Annual Debt Service.
• Many lenders want DSCR ≥ 1.20×–1.25× on 1–4 unit investor deals; multifamily often targets higher. Requirements vary by lender/program.
• LTV caps and rate quotes depend on DSCR, credit, reserves, property type, and market risk.
• Documentation: rent schedule/lease(s), market rent comp(s), T-12 or pro-forma, taxes/insurance quotes, appraisal with income approach.

What are DSCR loans (and why investors use them)?

DSCR loans (Debt Service Coverage Ratio loans) underwrite primarily to the property’s income rather than your W-2s or tax returns. If the building pays its own debt with a safety margin, you can often qualify without full-doc personal income. That’s attractive for investors with variable income or multiple properties.

How lenders calculate DSCR

DSCR = NOI ÷ Annual Debt Service

NOI = Market Rent (or Lease) − Vac/Collection − Taxes − Insurance − HOA/Utilities (where landlord-paid) − Professional Management (if applicable) − Maintenance/Reserves.

Annual Debt Service = Principal + Interest (and sometimes HOA special assessments if financed).

Note: “NOI” conventions vary. Many programs impute a management line even if you self-manage. Always ask for the lender’s DSCR worksheet so your underwriting matches theirs.

Typical requirements for DSCR loans

• Minimum DSCR: commonly 1.20×–1.25× for 1–4 unit investor loans; higher for small multifamily or riskier markets.
• LTV limits: purchase and rate/term refi often higher LTV than cash-out refi (cash-out typically capped lower).
• Credit & reserves: mid-score floors and months-of-reserves vary; more reserves can offset risk elsewhere.
• Seasoning: cash-out refi may require time in title; “delayed financing” exceptions sometimes apply after a cash purchase.
• Appraisal: expect income approach (and sales comparison). Short-term rentals may require a two-tier analysis (market vs. actual STR income).

Rates & fees: what moves the needle

Quoted rates on DSCR loans typically float above conforming investment property rates and shift with market yields. Expect adjustments for lower DSCR, higher LTV, STR income, smaller loan sizes, condos/condotels, or rural locations. Watch add-ons: points, lender fees, prepay penalties (yield maintenance or step-downs), and escrow requirements.

4 real examples (with math)

Numbers are rounded. Always re-compute to your lender’s DSCR worksheet and today’s rate environment.

Example 1 — 1–4 unit, long-term rental

• Purchase price: $350,000; 20% down; loan $280,000 @ 6.6% (≈$1,788/mo; $21,456/yr)
• Market rent: $2,600/mo; Vacancy 5% → $2,470/mo
• Taxes/Ins/HOA/Mgmt/Maint: $1,050/mo total
• NOI ≈ ($2,470 − $1,050) × 12 = $17,040
• DSCR = $17,040 ÷ $21,456 = 0.79× → Fails typical minimum; needs more down, lower rate, or higher rent.

Example 2 — Same property with better terms

• 25% down; loan $262,500 @ 6.1% (≈$1,592/mo; $19,104/yr)
• NOI unchanged: $17,040 → DSCR = $17,040 ÷ $19,104 = 0.89× → Still light; tighten expenses or raise rent.

Example 3 — Duplex with stronger NOI

• Price $400,000; 25% down; loan $300,000 @ 6.3% (≈$1,856/mo; $22,272/yr)
• Gross rent $3,600/mo; Vacancy 5% → $3,420; Expenses $1,100/mo → NOI ≈ $2,320 × 12 = $27,840
• DSCR = $27,840 ÷ $22,272 = 1.25× → Meets common minimums for many DSCR loans.

Example 4 — STR (short-term rental) sensitivity

• Average monthly net varies by season; lender may haircut projected income or use long-term market rent.
• At NOI $36,000 and debt service $28,800 → DSCR = 1.25×. If NOI dips 15% in off-season, DSCR falls to 1.06×.

Lesson: Model off-season before you rely on peak-season numbers. Some lenders will underwrite DSCR loans to long-term market rent for conservatism.

9 steps to qualify (copy/paste checklist)

1. Get the DSCR worksheet your lender uses; mirror their inputs and vacancy/management assumptions.
2. Rebuild NOI bottoms-up: taxes, insurance, HOA, utilities you’ll pay, maintenance, and a management line item.
3. Pull market rent comps (or an appraiser rent schedule) if leases are new or you’re converting STR/LTR.
4. Quote insurance early—premiums can make or break DSCR in some markets.
5. Price two rate points (par and par+buy-down) and test DSCR at each.
6. Test LTV scenarios (e.g., 70–80%) to see where DSCR clears ≥1.20×–1.25× with a cushion.
7. Document reserves—months of PITI or DSCR-specific reserve math per program.
8. Review prepay penalties (2-3-5 year step-downs or yield maintenance) before you accept the term sheet.
9. Order the right appraisal (income approach needed; STR treatment clarified) to avoid rework.

7 costly mistakes to avoid

• Underwriting to seller pro-formas. Always re-build NOI with your own taxes/insurance quotes.
• Ignoring reserves and liquidity. Thin cash is the #1 deal killer after DSCR itself.
• Misreading STR income. Lenders may haircut or default to long-term rent—ask before you contract.
• Skipping rate/DSCR sensitivity. Model ±100–200 bps and ±10–15% NOI to see breakpoints.
• Forgetting tax impacts. Depreciation helps after-tax returns; cash-out refi may change basis and interest deductions—talk to a tax pro.
• Assuming max LTV on cash-out. Cash-out LTV typically lower than purchase or rate/term refi.
• Signing heavy prepay without a plan. If you might sell/refi soon, negotiate a shorter step-down.

FAQ

What DSCR do I need? Many programs want ≥1.20×–1.25× for 1–4 unit investor loans; higher thresholds are common for small multifamily. Ask for the lender’s matrix.

Are rates higher than conforming? Often, yes. DSCR loans usually price above agency investment rates. Get multiple quotes and compare all-in APR with points and prepay terms.

Can I self-manage? Yes, but many lenders still include a management cost in NOI for underwriting.

Can I use STR income? Some lenders allow it with history; others underwrite to market long-term rent. Clarify early.
