San Diego stands as one of the strongest real estate investment markets in California, with a county GDP of $267 billion, a military economy contributing $61.3 billion in annual output, and a thriving biotech corridor that collectively drive sustained rental demand. For real estate investors, DSCR (Debt Service Coverage Ratio) loans offer a pathway to financing that relies on property cash flow rather than personal income verification, making them particularly well-suited to San Diego's high-value rental market.
Whether you are eyeing a multifamily property in North Park, a short-term rental in Pacific Beach, or an ADU conversion in Chula Vista, understanding how DSCR loans work in San Diego can help you build a profitable portfolio in America's Finest City.

What Is a DSCR Loan and How Does It Work in San Diego?
A DSCR loan qualifies borrowers based on the rental income a property generates relative to its monthly debt obligations. Instead of requiring W-2s, tax returns, or employment verification, lenders evaluate whether the property's income can cover the mortgage payment, property taxes, insurance, and any HOA fees.
The formula is straightforward:
DSCR = Gross Rental Income / Total Debt Service (PITIA)
A DSCR of 1.25 means the property generates 25% more income than needed to cover its debt payments. Most lenders prefer a minimum DSCR of 1.0, though ratios of 1.25 or higher unlock better rates and terms.
In San Diego, where the median home price sits around $875,000 and rental demand remains strong across virtually every submarket, DSCR loans solve a critical problem: many successful investors, self-employed professionals, and business owners cannot show the personal income documentation that conventional lenders require, even though their properties generate substantial cash flow.
Why Is San Diego Such a Strong Market for DSCR Loan Investors?
San Diego's investment appeal comes from the convergence of several powerful economic forces that create reliable, long-term rental demand.
Military and Defense Employment: The military supports nearly 357,000 local jobs and accounts for 22.2% of the region's Gross Regional Product. With $39.3 billion in direct defense spending and contracts awarded to over 2,000 companies, this sector provides a steady flow of tenants, particularly around bases like Naval Base San Diego, Marine Corps Air Station Miramar, and Camp Pendleton to the north. Military personnel and defense contractors represent a dependable tenant pool that is largely recession-resistant.
Biotech and Life Sciences: San Diego has the third-largest concentration of biotech companies among all U.S. metro areas, with more than 32,000 jobs across 499 companies in the Sorrento Valley corridor and surrounding areas. These high-income professionals need housing, and many prefer to rent given the region's elevated home prices.
Tourism Economy: With over 35 million annual visitors drawn to beaches, Balboa Park, the San Diego Zoo, and the Convention Center, the tourism sector supports robust short-term rental demand in designated areas.
Young Demographics: San Diego's median age is 34.9, with 25% of residents under 20. This youthful population drives rental demand as younger households delay homeownership due to high property values.
What Are Current DSCR Loan Rates and Terms in San Diego?
As of early 2026, DSCR loan rates have improved significantly compared to 2023 and 2024. Here is what investors can expect when financing San Diego investment properties:
Interest Rates: DSCR loan rates currently range from approximately 5.99% to 6.62%, depending on your credit score, LTV ratio, and the property's DSCR. This represents a meaningful decline from the 8% to 9% range seen throughout much of 2024.
Down Payment: Most DSCR lenders require 20% to 25% down for standard investment properties. Higher-value properties or lower credit scores may require 25% to 35% down.
Credit Score Requirements: A minimum credit score of 620 is standard, though scores of 720 or higher will secure the most competitive rates.
Loan Amounts: DSCR loans in San Diego typically range from $150,000 to $3 million or more, accommodating everything from a condo in El Cajon to a multifamily building in Hillcrest.
Prepayment Penalties: Most DSCR loans include prepayment penalty structures, commonly 5-4-3-2-1 or 3-2-1 formats, meaning the penalty decreases each year.
Loan Terms: 30-year fixed-rate options are standard, with some lenders offering 5/1 or 7/1 ARM products at lower initial rates.

Which San Diego Neighborhoods Offer the Best DSCR Loan Opportunities?
San Diego's diverse neighborhoods present different investment profiles for DSCR loan borrowers. The key is matching property type and rental strategy to the right submarket.
North Park and Hillcrest: These urban neighborhoods attract young professionals and offer strong long-term rental demand. Median home prices range from $650,000 to $850,000, and walkability combined with nightlife and dining make units easy to fill. Two-to-four-unit properties in these areas often achieve DSCR ratios above 1.2.
Pacific Beach and Ocean Beach: Coastal communities where median values reach $1.39 million (Pacific Beach). Short-term rental potential exists under San Diego's STRO licensing system, though whole-home vacation rentals are capped at 1% of housing stock citywide. Long-term rentals to young professionals and military-affiliated tenants also perform well here.
Chula Vista: With median prices around $750,000 to $760,000, Chula Vista offers a more affordable entry point compared to coastal neighborhoods. The city's ongoing bayfront development and proximity to the border create consistent demand. Cap rates here tend to run higher than coastal areas, often reaching 5% to 6%.
La Mesa and El Cajon: East County markets provide the most accessible price points in the San Diego metro. Median prices fall well below the county average, making it easier to achieve favorable DSCR ratios. These areas attract families and military personnel stationed at nearby installations.
Escondido and Vista: North County inland markets with emerging investment potential. Escondido's cap rates reach 5% to 6%, offering higher returns for investors willing to look beyond the coast. Brewery districts, downtown revitalization projects, and growing transit connections add to the appeal.
How Do San Diego's Short-Term Rental Regulations Affect DSCR Loans?
San Diego's short-term rental landscape is governed by the Short-Term Residential Occupancy (STRO) ordinance, and understanding these regulations is essential for investors planning to use rental income for DSCR qualification.
License Tiers: The city operates a four-tier licensing system. Tier 1 allows up to 20 rental days per year ($226 annual fee). Tiers 3 and 4 permit full-time vacation rental operation ($1,170 annual fee) but are subject to the citywide cap of approximately 5,400 whole-home rentals.
Mission Beach Exception: Vacation rentals can equal up to 30% of Mission Beach's housing stock, translating to roughly 1,100 permitted STRs, making this the densest short-term rental zone in the city.
Tax Obligations: As of May 2025, San Diego implemented a tiered Transient Occupancy Tax (TOT) based on proximity to the Convention Center. Zone 1 properties pay 11.75%, Zone 2 pays 12.75%, and Zone 3 (closest to the Convention Center) pays 13.75%.
ADU Restriction: Accessory dwelling units built after January 1, 2020 cannot be used for short-term rentals, a rule designed to preserve affordable long-term housing.
DSCR Implications: When underwriting a DSCR loan for a short-term rental property, lenders will evaluate projected rental income carefully. Properties with existing STRO licenses and documented rental history will qualify more easily than speculative STR income projections. Many investors find that long-term rental income provides a more straightforward path to DSCR qualification.
What Role Does the ADU Boom Play in San Diego DSCR Lending?
California's progressive ADU legislation has made San Diego one of the most active ADU markets in the state, and these secondary units create compelling opportunities for DSCR loan investors.
Current Allowances: Single-family lots in San Diego can have up to three ADUs by right: one detached ADU, one conversion from existing space, and one Junior ADU (up to 500 sq. ft.). The Affordable ADU Bonus Program can bring the total to five units on a single lot.
SB 1211 (January 2025): Multifamily property owners can now build as many ADUs as there are existing units, with a maximum of eight detached ADUs. No owner-occupancy restrictions apply.
AB 1033 Adoption: San Diego became the first city in the county to allow the sale of ADUs as separate units, creating new exit strategies for investors.
Size Standards: ADUs range from 150 to 1,200 square feet, with Junior ADUs capped at 500 square feet.
For DSCR loan purposes, adding an ADU to a property can dramatically improve the debt service coverage ratio. A property that generates $3,000 per month in rent from the primary unit might add $1,500 to $2,000 monthly with a well-positioned ADU, potentially pushing a marginal DSCR above the 1.25 threshold that unlocks premium loan terms.
If you need short-term financing to acquire and renovate a property before adding an ADU, explore bridge loan options that can transition into permanent DSCR financing.
What DSCR Ratio Do You Need for San Diego Investment Properties?
The required DSCR varies based on the lender, loan amount, and property type, but here are the general thresholds San Diego investors should target:
1.0 DSCR (Break-Even): The property's income exactly covers its debt service. Some lenders now accept 1.0 DSCR for well-qualified borrowers with strong credit scores (740+) and lower LTV ratios. Rates will be higher at this level.
1.15 to 1.20 DSCR: A comfortable range that most lenders consider acceptable. You will have access to standard DSCR loan products with competitive terms.
1.25+ DSCR: The sweet spot for the best rates and terms. At this level, the property generates 25% more income than needed, providing a healthy cushion for vacancies, maintenance, and market fluctuations.
No-Ratio Programs: Some lenders offer DSCR loans without a minimum ratio requirement, though these come with rate premiums of 0.5% to 1.0% above standard DSCR products.
Given San Diego's high property values, achieving strong DSCR ratios requires careful property selection. Areas like Escondido, El Cajon, and Vista, where purchase prices are lower relative to achievable rents, tend to produce better DSCR numbers than premium coastal locations where property values are high relative to rental income.
How Does the DSCR Loan Application Process Work?
Securing a DSCR loan for a San Diego investment property follows a streamlined process compared to conventional financing. Here is what to expect from start to close:
Step 1: Property Analysis. Before applying, run the numbers using a commercial mortgage calculator to estimate your monthly payment, then calculate the expected DSCR using projected or actual rental income.
Step 2: Lender Selection. Not all DSCR lenders serve the San Diego market equally. Look for lenders experienced with California investment properties, familiar with local rental comps, and offering competitive terms for your specific property type.
Step 3: Application and Documentation. You will provide property details, a rent roll or market rent analysis, proof of funds for the down payment, and authorize a credit check. Unlike conventional loans, you will not need to submit tax returns, W-2s, or employment verification.
Step 4: Appraisal and Rent Analysis. The lender orders an appraisal that includes a rental income analysis (Form 1007 for single-family or Form 216 for multifamily). This establishes the market rent the property can command.
Step 5: Underwriting. The lender evaluates the DSCR, LTV, credit score, and property condition. Most DSCR loans close in 21 to 30 days, faster than many conventional investment property loans.
Step 6: Closing and Funding. Once approved, you close on the property and begin generating rental income.
What Are Common Mistakes San Diego DSCR Loan Borrowers Make?
Avoiding these pitfalls can save you time, money, and frustration when pursuing DSCR financing in San Diego.
Overestimating Rental Income: San Diego's average apartment rent is approximately $2,938, but this varies dramatically by neighborhood and unit type. Use conservative estimates based on comparable properties in the specific submarket, not citywide averages.
Ignoring Vacancy Assumptions: San Diego's vacancy rate reached 5.7% in late 2025, the highest since 2009, driven by a surge in new apartment deliveries. Budget for 5% to 8% vacancy in your DSCR calculations rather than assuming 100% occupancy.
Underestimating Insurance Costs: California's insurance market has tightened considerably. Wildfire risk, coastal exposure, and rising replacement costs mean insurance premiums may be higher than expected, directly impacting your DSCR.
Overlooking HOA Fees: Condo investments in areas like Pacific Beach or downtown San Diego may carry HOA fees of $400 to $800 or more monthly, which are included in the DSCR calculation and can significantly reduce your ratio.
Not Accounting for Short-Term Rental Regulations: Purchasing a property with the intention of running a short-term rental without securing a STRO license first can leave you with income projections that cannot be realized.
How Do San Diego DSCR Loans Compare to Conventional Investment Loans?
Understanding the differences between DSCR loans and conventional investment property mortgages helps you choose the right financing for your situation.
Conventional investment loans require full income documentation, typically limit investors to 10 financed properties, and use debt-to-income ratios for qualification. DSCR loans bypass income verification entirely, have no cap on the number of properties you can finance, and qualify based solely on the property's cash flow.
The trade-off comes in pricing. DSCR loans typically carry rates 0.5% to 1.5% higher than conventional investment property loans. However, for investors who cannot document sufficient personal income, who own multiple properties already, or who want to scale their portfolios quickly, the premium is well worth the flexibility.
For San Diego investors specifically, DSCR loans are particularly valuable because the region's high property values mean larger loan amounts, and the strong rental market provides the income to support those larger balances.
Frequently Asked Questions About San Diego DSCR Loans
Can I use a DSCR loan to buy a short-term rental in San Diego? Yes, DSCR loans can finance short-term rental properties in San Diego, but you must comply with the city's STRO licensing requirements. Lenders will evaluate the property's rental income potential, and documented STR income from an existing operation strengthens your application. Keep in mind that whole-home vacation rentals are capped citywide at roughly 5,400 units, and ADUs built after January 2020 cannot be used as short-term rentals.
What credit score do I need for a San Diego DSCR loan? Most lenders require a minimum credit score of 620, but scores of 680 or higher will qualify you for significantly better rates. Borrowers with 740+ credit scores paired with a DSCR of 1.25 or higher receive the most competitive terms available.
Can I finance an ADU addition with a DSCR loan? DSCR loans are primarily for acquiring or refinancing rental properties. If you are looking to finance construction of a new ADU, a bridge loan or renovation loan may be more appropriate for the construction phase, which can then be refinanced into a DSCR loan once the ADU is complete and generating rental income.
How many properties can I finance with DSCR loans in San Diego? There is no limit on the number of properties you can finance with DSCR loans, which is one of their primary advantages over conventional financing that caps investors at 10 mortgages. Each property is evaluated independently based on its own cash flow.
Do I need reserves for a San Diego DSCR loan? Yes, most lenders require 3 to 6 months of principal, interest, taxes, and insurance (PITI) payments in liquid reserves. Given San Diego's higher property values and corresponding larger loan amounts, reserve requirements can be substantial. Plan for $15,000 to $30,000 or more in reserves depending on the property.
What property types qualify for DSCR loans in San Diego? Eligible property types include single-family homes, condos, townhomes, 2-4 unit multifamily properties, and in some cases small apartment buildings (5+ units). The property must be intended for rental use. Owner-occupied properties do not qualify for DSCR financing.
