DSCR Is Not One Number

When operators say "DSCR" they mean different things depending on context. Different lenders use different formulas. Different property types attract different thresholds. Knowing the variations matters when you are underwriting your refi exit.

The Standard Formula

DSCR equals NOI divided by annual debt service.

Some lenders use a variant: PITIA-based DSCR equals monthly rent divided by monthly PITIA (Principal, Interest, Taxes, Insurance, Association dues). This treats taxes and insurance like debt service for sizing purposes.

The PITIA version is more common for online DSCR lenders working on 1 to 4 unit residential. The NOI version is standard for 5-plus unit multifamily and commercial.

DSCR Targets By Property Type

1 to 4 unit residential (SFR rentals, duplex, triplex, quadplex):

  • Online DSCR lender minimum: 1.0 (some go to 0.75 with high credit and reserves)
  • Conventional Fannie/Freddie investor loan: 1.0 to 1.20
  • Conservative lender: 1.20 to 1.25

5 to 10 unit small multifamily:

  • Specialty DSCR lender: 1.10 to 1.20
  • Community bank: 1.20 to 1.25
  • Most lenders require this be the borrower's primary asset class focus

11 to 30 unit mid-multifamily:

  • Specialty multifamily lender: 1.20 to 1.25
  • Community bank: 1.25
  • Bank credit committees scrutinize more

31-plus unit multifamily:

  • Agency (Fannie/Freddie/HUD): 1.20 to 1.25 with some flex
  • CMBS: 1.25 to 1.40
  • Bank balance sheet: 1.20 to 1.30

Mixed-use (retail down, residential up):

  • Highly lender-dependent: 1.20 to 1.30
  • Often falls back to community bank since CMBS treats mixed-use harshly

Self-storage:

  • Specialty lender: 1.20 to 1.30
  • Some go higher because of perceived volatility

Commercial (office, retail, industrial):

  • 1.25 to 1.40 depending on tenant strength
  • Single-tenant net lease can go to 1.10 to 1.20 if the tenant is investment grade

Lender Variations

Online DSCR lenders (Visio, Kiavi, Lima One, CoreVest):

  • Use PITIA-based DSCR primarily
  • Tier rates by DSCR brackets: lowest rate at 1.25 plus, higher rates at 1.0 to 1.25, highest rates below 1.0
  • Standardized programs, minimal flex

Community banks:

  • Use NOI-based DSCR
  • Apply their own vacancy, reserve, and management add-backs
  • Will sometimes accept 1.10 from a strong borrower with relationship

Agency lenders (Fannie Small Loans, Freddie Small Balance):

  • Use stabilized NOI with prescribed underwriting standards
  • Strict minimum DSCR (1.20 to 1.25)
  • Take longer to close

CMBS:

  • Use stabilized NOI with conservative underwriting
  • Typically 1.25 plus on multifamily, 1.40 plus on commercial
  • Only for larger loans ($1M-plus)

The Hidden DSCR Calculation Issue

Two lenders looking at the same property can calculate different DSCRs because of underwriting normalization differences.

Example:

  • Subject property: 12-unit, your reported NOI: $90,000, your debt service request: $75,000
  • Your reported DSCR: 1.20

But lender adjustments:

  • Adds 5 percent vacancy (you claimed 2 percent): subtracts $4,800
  • Adds 8 percent management fee (you self-manage): subtracts $11,500
  • Adds $300 per unit replacement reserves: subtracts $3,600
  • Lender-recognized NOI: $70,100
  • Lender-calculated DSCR: $70,100 / $75,000 equals 0.93

That deal does not qualify at the lender's threshold even though your numbers showed 1.20.

This is why pre-refi due diligence matters. Underwrite with lender-style adjustments, not your operational best-case.

What To Do When DSCR Is Tight

If your underwriting shows DSCR will be tight:

Option 1: Wait for more stabilization. Time lets rents grow into market and operating numbers normalize.

Option 2: Bring more cash to refi. Reducing the loan amount improves DSCR.

Option 3: Different lender. Some lenders allow lower DSCR with higher rates or higher equity.

Option 4: Restructure as a bridge. Bridge lender at higher rate, then permanent loan after another 12 months of stabilization.

Option 5: Sell instead of refi. If the deal cannot support permanent financing at reasonable terms, it may not be the long-term hold you thought.

DSCR Trends That Matter

DSCR thresholds tighten when:

  • Interest rates rise (debt service increases for the same loan amount)
  • Lenders pull back from risk
  • Asset class falls out of favor

DSCR thresholds loosen when:

  • Capital is abundant
  • Asset class is in demand
  • Borrower has track record and reserves

Lock in long-term debt during loose-DSCR periods. Avoid being forced to refinance during tight-DSCR periods.

The DSCR Underwriting Discipline

For every seller-financed acquisition, calculate your projected refi DSCR before you close.

Stabilized NOI estimate divided by projected refi debt service. If you cannot show 1.20 plus at projected refi, the deal is leveraged tightly on assumptions going right.

Walking away from a tight-DSCR deal hurts in the moment. Holding a property you cannot refi out of hurts for years.
