Financing a short-term rental (STR) in California is fundamentally different from financing a traditional investment property — and most conventional lenders aren’t equipped to handle it. Short-term rental income is variable, seasonally driven, and doesn’t appear on tax returns the way W-2 or self-employment income does.
That’s where short-term rental loans come in. DiVita Home Finance works with a specialized network of 40+ wholesale lenders who offer STR mortgage products designed specifically for Airbnb, VRBO, and other vacation rental properties across California. These loans qualify you based on the property’s projected or actual rental income — not your personal income, not your tax returns, and not your W-2s.
How Short-Term Rental Loans Work in California
Short-term rental loans in California are typically structured as DSCR loans (Debt Service Coverage Ratio loans) — a category of non-QM lending where the property’s income-to-debt ratio is the primary underwriting criteria. Unlike conventional loans, there is no personal income verification.
The key question for STR lenders: Does the property generate enough rental income to cover the mortgage?
For short-term rentals, lenders calculate projected income one of three ways:
- AirDNA income projection: The most common method. AirDNA is an industry-leading STR analytics platform that aggregates actual booking data from Airbnb and VRBO. For any property address, AirDNA can project annual gross revenue based on comparable STR properties in the same market. Lenders apply a 75–80% haircut to the projected figure to account for vacancy and management costs, then use that number to calculate the DSCR.
- 12-month actual revenue history: If you’ve been operating the property as an STR for at least 12 months, lenders will use your actual gross receipts from Airbnb/VRBO payout statements. This is ideal if your property outperforms the market average.
- Appraiser STR income addendum: Some lenders commission a specialized appraisal that includes an STR income projections page. The appraiser assesses typical nightly rates, occupancy for the market, and seasonality to project annual revenue.
Once income is established, the DSCR is calculated: Monthly STR Income ÷ Monthly PITIA = DSCR. Most lenders want 1.0 or above. Some allow below 1.0 with higher down payment and stronger credit.
Best California Markets for Short-Term Rental Investment (2026)
Not all California markets are equal for STR investors. The most successful STR investments combine strong demand drivers (tourism, events, outdoor recreation) with favorable local regulations. Here are California’s top STR markets and what you need to know:
Palm Springs & Coachella Valley
STR Status: Highly favorable. Palm Springs is one of the most Airbnb-friendly cities in California and in the country. The city actively licenses STRs, and there are no caps on the number of permits. Desert modernist architecture, year-round golf, Coachella Festival, and the shoulder-season shoulder demand create exceptional revenue. AirDNA data for Palm Springs typically shows annual gross revenue of $45,000–$85,000+ for 3–4 bedroom homes, making DSCR qualification relatively straightforward even at today’s rates.

Big Bear Lake & Lake Arrowhead
STR Status: Favorable, with permit requirements. The San Bernardino mountain resort communities permit STRs with a business license. Big Bear Lake generates strong winter ski-season demand plus summer lake activity — a dual-season profile that keeps occupancy high year-round. AirDNA projections for Big Bear are typically $35,000–$65,000 annually. Properties near Snow Summit or the lake command significant premiums.

Lake Tahoe (South Lake Tahoe, Truckee, Tahoe City)
STR Status: Varies by jurisdiction — research before buying. South Lake Tahoe has implemented STR caps (capped at approximately 1,900 permits) with a waitlist and compliance requirements. Truckee and Tahoe City have their own permit frameworks. Despite regulatory complexity, existing licensed STRs in Tahoe command some of California’s highest revenue — $80,000–$150,000+ annually for premium lakefront or ski-in/ski-out properties. If you already hold a permit, or are buying a property with a transferable permit, Tahoe STR DSCR loans are very viable.
Joshua Tree & Yucca Valley
STR Status: Favorable, permit required. The Joshua Tree National Park adjacency drives extraordinary demand for unique, architecturally interesting STR properties — geodesic domes, desert modernist retreats, container homes. The unincorporated areas of San Bernardino County (which include much of the Joshua Tree STR market) permit STRs with a county license. Revenue varies widely by property quality and uniqueness, ranging from $25,000 to $80,000+ annually. Niche/design properties significantly outperform generic listings.

Sonoma & Napa Wine Country
STR Status: Varies — Sonoma more favorable than Napa. Sonoma County permits STRs with a license (capped at 1,200 permits county-wide). Napa County restricts STRs significantly, with very limited permits in unincorporated areas and bans within city limits in most municipalities. Wine country STRs generate premium revenue from harvest-season demand (September–November), weddings, and culinary tourism. AirDNA projections for Sonoma wine country range from $40,000–$90,000 annually.

San Diego & Oceanside
STR Status: Regulated but permissible. San Diego requires an STR license (Tier 2 for whole-home rentals), with no cap as of 2026 but compliance audits. Oceanside has a streamlined permit process and is popular with military families and beach tourists. Year-round demand from military activity, tourism, and conferences supports consistent STR revenue. Coastal properties generate $50,000–$100,000+ annually.
California Cities That Restrict or Ban Short-Term Rentals
Before purchasing an STR investment property in California, understanding the regulatory environment is critical. These cities have significant restrictions:
| City/Area | STR Status | Key Rule |
|---|---|---|
| Santa Monica | Heavily restricted | Host must be on-site during guest stays; no whole-home rentals while away |
| San Francisco | Primary residence only | Must be your primary residence; maximum 90 unhosted nights/year |

| Beverly Hills | Banned | STRs prohibited entirely |
| Calistoga | Banned | STRs prohibited entirely |
| Concord | Banned | STRs prohibited entirely |
| Marin County | Capped | County-wide permit cap at 1,200; waitlist likely |
| Napa (unincorporated) | Heavily restricted | Very limited permits; most municipalities ban within city limits |
| South Lake Tahoe | Capped | ~1,900 permit cap with compliance requirements and waitlist |
Important: STR regulations change frequently. Always verify current local regulations with the specific city or county before purchasing an STR investment property. DiVita Home Finance can connect you with local real estate attorneys who specialize in STR compliance.

Why Use a Broker for Your STR Loan?
Not all DSCR lenders accept STR income, and among those that do, there is enormous variation in how they calculate income (AirDNA vs. actual vs. appraiser) and how aggressively they price the loan. The difference between a well-shopped STR loan and a poorly shopped one can be 0.5%–1.0% in rate — thousands of dollars per year in interest.
DiVita Home Finance has deep relationships with STR-specialized wholesale lenders and knows exactly which ones:
- Accept AirDNA income without requiring 12 months of actual history
- Offer the most competitive rates for California STR markets
- Allow lower DSCR ratios for high-quality properties and strong borrowers
- Handle non-warrantable condos in resort markets
- Work with foreign national investors purchasing U.S. STRs
Frequently Asked Questions: Short-Term Rental Loans
Can I use projected Airbnb income to qualify for a mortgage?
Yes — through a DSCR STR loan, lenders use AirDNA market projections to estimate your property’s annual Airbnb or VRBO revenue. They then apply a 75–80% haircut and use that figure as qualifying income for the DSCR calculation. No personal income, W-2s, or tax returns are required.
Do I need to already own the property or have a rental history?
No. For purchase loans, lenders use AirDNA projections or an appraiser’s STR income addendum — no prior rental history required. You can finance your first Airbnb investment property using projected income.
What if my target city has STR restrictions?
Many STR-restricted cities (LA, SF, Santa Monica) only allow primary residence STRs. DSCR STR loans are intended for investment properties, not primary residences. Before proceeding, verify that the specific property you’re targeting is legally permitted to operate as a short-term rental investment. We can help you evaluate markets where STR investment is feasible.
What’s the minimum credit score for an STR loan?
Most STR DSCR lenders require a minimum of 660–680. A higher credit score (720+) will significantly improve your rate. STR loans are priced slightly higher than long-term rental DSCR loans due to the income variability.
Can I refinance my existing Airbnb with an STR loan?
Yes. STR DSCR loans are available for rate-and-term refinances and cash-out refinances (up to 75% LTV). If you’ve built equity in an existing STR property, a DSCR cash-out refinance can fund your next acquisition without selling.
