A DSCR loan for short-term rentals in California lets you finance an Airbnb, VRBO, or vacation rental property based on the property’s projected income — not your personal tax returns or W-2s. It’s the most powerful financing tool available for California STR investors, and DiVita Home Finance specializes in getting these deals done.

How STR Income Is Calculated for a DSCR Loan
This is the question every Airbnb investor asks — and the answer is better than most people expect. For short-term rental DSCR loans, lenders use one of three income sources:
| Income Source | When Used | Notes |
|---|---|---|
| AirDNA Market Data | New purchases with no rental history | Projected annual revenue for your specific address, typically at 75–80% of gross |
| 12-Month Actual History | Properties with existing STR track record | Bank statements or platform payouts used; lender averages the 12 months |
| STR Appraisal Narrative | Either new or existing | Licensed appraiser provides a short-term rental income narrative as part of the appraisal |
Key point: You do NOT need an existing rental history to qualify. AirDNA data for your specific California market — whether that’s Lake Tahoe, Palm Springs, Big Bear, Sonoma Wine Country, or Santa Barbara — can be used for DSCR qualification on a new purchase. This is a game-changer for first-time STR investors.
DSCR Calculation for Short-Term Rentals
DSCR = Monthly Rental Income ÷ Monthly PITIA (Principal + Interest + Taxes + Insurance + HOA)
For STR properties, “monthly rental income” is typically the AirDNA-projected annual gross revenue divided by 12, then multiplied by 0.75–0.80 to account for vacancies and platform fees. A DSCR of 1.0 means the property breaks even on debt service. Most lenders want 1.0 or higher, though no-ratio programs exist for properties under 1.0.
Example — Lake Tahoe cabin, $850,000 purchase, 25% down:
| Item | Amount |
|---|---|
| Purchase price | $850,000 |
| Down payment (25%) | $212,500 |
| Loan amount | $637,500 |
| PITIA (7.50% / 30yr) | ~$5,200/month |
| AirDNA projected gross revenue | $96,000/year ($8,000/month) |
| Income used (75%) | $6,000/month |
| DSCR | 1.15 ✅ Qualifies |

California STR Regulations to Know Before You Buy
Before financing a California STR property, verify local regulations. Several cities have restricted or banned short-term rentals:
- San Francisco: Must be primary residence; 90-night annual cap for unhosted rentals
- Los Angeles: Must be primary residence; 120-night annual cap
- Santa Monica: Home-sharing only (must be primary residence)
- Palm Springs: STR-friendly with permit; vacation rental overlay zones apply
- Lake Tahoe: El Dorado and Placer County each have separate STR permit systems
- Marin County / Unincorporated: Generally permit-based; check specific municipality
Vacation rental permissibility affects the STR appraisal and income projections. We always recommend confirming local STR ordinances before purchasing.
Frequently Asked Questions — STR DSCR Loans California
Can I use a DSCR loan for an Airbnb property in California?
Yes. DSCR loans are the primary financing vehicle for California Airbnb and vacation rental investors. Income is qualified using AirDNA projections, your 12-month STR history, or an appraiser’s STR income narrative — not your personal tax returns.
Do I need prior Airbnb hosting experience to qualify?
No. First-time STR investors qualify using AirDNA market data for the property’s address. No hosting history is required.
What is AirDNA and how does it affect my DSCR?
AirDNA is a data platform that aggregates short-term rental performance data from Airbnb, VRBO, and other platforms. Lenders use AirDNA’s projected annual revenue for your specific address to estimate income for DSCR qualification. Most lenders apply a 75–80% haircut to gross projections to account for vacancies, cleaning fees, and platform costs.
What if the seasonal income makes my DSCR below 1.0?
If your projected DSCR falls below 1.0, a no-ratio DSCR program may still allow financing with 30% down and a stronger credit profile. Alternatively, a 40-year interest-only loan can reduce your monthly PITIA enough to push DSCR above 1.0.
Can I finance an Airbnb condo in California?
Yes, but the condo must be warrantable or financed through a non-QM program. Many vacation condo complexes are non-warrantable (especially condotels), which requires specialized financing. We handle both — call us to discuss your specific property.
