[DSCR](/blog/what-is-dscr-ratio) Loans for Commercial Mixed-Use Properties

Mixed-use properties—buildings combining residential units with commercial space (retail, office, restaurant)—represent one of real estate's most lucrative but misunderstood investment categories. While traditional lenders push these properties into complex commercial financing, [[[DSCR loans](/blog/dscr-loan-guide)](/blog/best-dscr-lenders-2026)](/blog/dscr-loan-guide) offer a simpler path for the right deals.

The key is understanding which mixed-use configurations qualify for residential DSCR treatment versus which require true commercial loans.

What Qualifies as Mixed-Use?

Mixed-use properties combine two or more distinct uses in one building or development.

Common configurations:

Vertical mixed-use:

• Ground floor: Retail/office/restaurant
• Upper floors: Residential apartments or condos

Example: Urban building with café on first floor, 4 apartments above

Horizontal mixed-use:

• Separate buildings on same parcel
• One or more commercial, one or more residential

Example: Strip mall with 3 retail units + 2 residential apartments in back

Live-work spaces:

• Combined residential and business use in same unit
• Common for artists, consultants, small businesses

Example: 1,500 sq ft space with storefront and living quarters behind

The 50% Residential Rule

Most DSCR lenders follow a critical threshold: If 51% or more of the building's income comes from residential use, it can qualify for residential DSCR treatment.

This rule transforms financing complexity:

51%+ residential income:

• Residential DSCR loan (simpler)
• 30-year amortization
• Residential appraisal
• Standard residential underwriting

50% or less residential income:

• Commercial loan required
• 20-25 year amortization
• Commercial appraisal
• More stringent underwriting

Example 1: Qualifies for DSCR

• Ground floor retail: $2,000/month
• 3 apartments: $1,500 each = $4,500/month
• Total income: $6,500/month
• Residential %: $4,500 ÷ $6,500 = 69%
• Qualifies for residential DSCR loan ✓

Example 2: Requires commercial loan

• Ground floor restaurant: $5,000/month
• 2 apartments: $1,800 each = $3,600/month
• Total income: $8,600/month
• Residential %: $3,600 ÷ $8,600 = 42%
• Requires commercial financing ❌

How Lenders Underwrite Mixed-Use DSCR Loans

Income Calculation

Lenders analyze both income streams separately, then combine them:

Residential income:

• Treated like standard DSCR rental income
• Lease agreements or market rent analysis
• Minimal haircut (5-10% for vacancy)

Commercial income:

• Requires lease agreements (no "market rent" assumptions)
• Higher haircut (15-25% for risk and vacancy)
• Scrutiny of tenant creditworthiness
• Lease term remaining (short leases = higher risk)

Combined DSCR formula: DSCR = (Residential Income + Commercial Income × Haircut) ÷ PITIA

Example Calculation

Property: 3-story building

• Units: 4 apartments + 1 ground-floor retail
• Apartment rent: $1,400 each = $5,600/month
• Retail lease: $2,400/month (3 years remaining)

Lender income calculation:

• Residential: $5,600 × 0.95 (5% vacancy) = $5,320
• Commercial: $2,400 × 0.80 (20% haircut) = $1,920
• Total qualifying income: $7,240/month

Loan details:

• Purchase price: $650,000
• Loan: $520,000 (80% LTV) at 7.75%
• P&I: $3,745
• Taxes: $650
• Insurance: $250
• Total PITIA: $4,645

DSCR: $7,240 ÷ $4,645 = 1.56 ✓

This property qualifies strongly due to high residential income percentage and solid commercial tenant.

• Residential income <40%

Requires: Commercial mortgage

3. Restaurant with Upstairs Apartment

• 1-2 small apartments
• Commercial income often >50%

Requires: Commercial mortgage (even if residential is 51%, restaurant risk profile changes underwriting)

• Warehouse, manufacturing, or industrial use
• Attached apartment or caretaker unit
• Different zoning, high liability

Requires: Commercial mortgage or specialized industrial lender

Underwriting Challenges and Solutions

Challenge 1: Proving Residential Income Dominance

Lenders require documentation proving 51%+ residential income.

Solution:

• Provide rent roll showing all units and income
• Lease agreements for commercial and residential
• Pro forma income statement breaking down sources
• Appraisal clearly allocating value to residential vs. commercial

Challenge 2: Commercial Tenant Credit Risk

If a commercial tenant represents 30-40% of income and has weak credit or short lease, lenders worry.

Solution:

• Target properties with strong commercial tenants (credit-worthy businesses, long leases)
• Provide tenant financial statements if possible
• Demonstrate low commercial space vacancy rates in area
• Show residential income alone can support debt service (commercial is "bonus")

Challenge 3: Valuation Complexity

Mixed-use appraisals are more complex than pure residential.

Solution:

• Use appraisers experienced with mixed-use properties
• Provide comparable sales of similar mixed-use buildings
• Request income approach appraisal (not just sales comps)
• Be prepared for longer appraisal timelines (2-4 weeks vs. 1-2 weeks)

Challenge 4: Zoning and Permitting

Mixed-use requires proper zoning. Illegal commercial conversions or unpermitted uses disqualify properties.

Solution:

• Verify zoning allows mixed-use before purchase
• Obtain certificate of occupancy showing legal commercial use
• Ensure all permits are in place for commercial operations
• Consult with zoning attorney if unclear

Challenge 5: Commercial Lease Expiration Risk

If commercial lease expires within 12 months, lenders discount that income heavily.

Solution:

• Time purchases around long-term commercial leases (3+ years remaining)
• Negotiate lease renewal before closing
• Demonstrate strong demand for commercial space (low vacancy, comparable leases)
• Ensure residential income alone meets 1.20 DSCR (commercial is bonus)

Maximizing DSCR on Mixed-Use Properties

Strategy 1: Optimize Residential Income

Residential income counts more favorably than commercial in DSCR calculations (lower haircut).

Tactics:

• Renovate residential units to command premium rents
• Maximize number of residential units
• Offer furnished or upgraded units for rent premiums

Example: Increasing residential rent from $1,200 to $1,400 per unit (4 units) adds $800/month qualifying income with minimal haircut.

Strategy 2: Secure Long-Term Commercial Leases

Lenders favor commercial tenants with 5+ year leases.

Tactics:

• Negotiate longer lease terms before purchase (seller incentive: stronger sale)
• Offer tenant improvements (TI) for long-term commitment
• Include rent escalation clauses (2-3% annual increases)

Impact: 5-year lease vs. 1-year lease can reduce lender haircut from 30% to 15%, significantly improving DSCR.

Strategy 3: Convert Marginal Commercial Space to Residential

If commercial income is 49% and DSCR is marginal, consider converting commercial to residential.

Example:

• Current: 3 apartments ($1,500 each) + retail ($2,500)
• Total: $7,000 (residential 64%)
• Convert retail to 2 apartments ($1,600 each)
• New total: $7,700 (residential 100%, higher net after lower commercial expenses)

Consideration: Requires zoning approval and market demand for additional residential units.

Strategy 4: Lease Commercial Space Below Market to Strong Tenant

Counterintuitively, accepting lower commercial rent for a creditworthy, long-term tenant improves DSCR.

Why: Lenders apply lower haircuts to strong tenants. A $2,000 lease to a solid tenant with 7 years remaining may count more than a $2,500 lease to weak tenant with 1 year left.

Calculation:

• Weak tenant: $2,500 × 0.70 = $1,750 qualifying income
• Strong tenant: $2,000 × 0.90 = $1,800 qualifying income

Plus, lower vacancy risk and consistent cash flow.

Strategy 5: Use Commercial NNN Leases

Triple-net (NNN) leases where tenant pays property taxes, insurance, and maintenance improve DSCR.

Why: Lender sees commercial space as lower-cost to landlord (tenant covers expenses).

Example:

• Gross lease: $2,500/month, landlord pays $400 expenses = $2,100 net
• NNN lease: $2,200/month, tenant pays expenses = $2,200 net

NNN structure may allow lender to count full $2,200 without expense deductions.

FAQ

Can I use a DSCR loan if commercial income is exactly 50%? It's a gray area. Most lenders require 51%+ residential to clearly qualify for residential treatment. If you're at 50/50, some lenders may still approve but with more conservative underwriting or slightly higher rates. Shop multiple lenders.

Do I need commercial property insurance for mixed-use? Yes. Standard residential [landlord insurance](/blog/landlord-insurance-guide) won't cover commercial operations. You need a mixed-use or commercial policy covering both uses. Lenders will verify appropriate coverage at closing.

Can I convert a fully residential property to mixed-use after getting a DSCR loan? Check your loan documents. Some loans restrict property use changes. Converting residential to commercial use may violate loan covenants or trigger due-on-sale clauses. Consult your lender before converting.

What if my commercial tenant vacates mid-loan? Your loan doesn't change, but cash flow suffers. You're responsible for debt service regardless of occupancy. This is why strong reserves (12-18 months) are critical for mixed-use properties.

Can I count residential income from a unit I occupy? No. DSCR loans are for investment properties only. If you owner-occupy any residential unit, the property may require different financing (conventional multi-unit with owner occupancy or mixed-use commercial loan).

Do lenders require personal guarantees on mixed-use DSCR loans? Generally no. True DSCR loans are non-recourse or limited recourse. However, some lenders may require guarantees on properties with significant commercial income (40-50% range).

What if zoning is mixed but current use is 100% residential? Lenders underwrite based on actual income, not potential. If all income is residential, it's treated as residential DSCR. The mixed-use zoning adds flexibility for future conversion but doesn't affect current underwriting.

Can I use projected commercial income from a vacant commercial space? Rarely. Most lenders require executed leases or won't count commercial income at all if vacant. Focus on ensuring residential income alone meets DSCR minimums.

Are mixed-use properties harder to sell than pure residential? Sometimes. Mixed-use appeals to investors, not owner-occupants, shrinking the buyer pool. However, strong cash flow often attracts investors willing to pay premium prices. Exit strategy depends on property performance.

Should I hire a commercial property manager or residential property manager? Ideally, hire a manager experienced with both. If you must choose, prioritize residential [property management](/blog/property-management-complete-guide) (since residential is the dominant income source) and self-manage the commercial relationship if it's a single, stable tenant.

---

Bottom Line: Mixed-use properties with 51%+ residential income can qualify for residential DSCR loans with 30-year terms and competitive rates, offering superior financing to commercial alternatives. Success requires strong residential income, creditworthy commercial tenants with long-term leases, proper zoning and permits, and lenders experienced with mixed-use underwriting. When structured correctly, mixed-use properties deliver superior DSCR ratios and cash flow compared to pure residential rentals while maintaining residential financing advantages.
