Quick Answer
What is a conventional loan in San Diego?
A conventional loan is a mortgage not backed by a government agency, conforming to Fannie Mae and Freddie Mac guidelines. The 2026 San Diego County conforming limit is $1,149,825. Minimum down payment is 3% for first-time buyers (5% for repeat buyers). PMI is required below 20% down but can be removed once equity reaches 20%, unlike FHA mortgage insurance.

What Is a Conventional Loan?
A conventional loan is a mortgage that is not insured or guaranteed by a government agency — unlike FHA, VA, or USDA loans. Instead, conventional loans are backed by private lenders and follow guidelines set by Fannie Mae and Freddie Mac, the two government-sponsored enterprises (GSEs) that purchase mortgages on the secondary market. This structure allows lenders to offer lower rates and more flexible terms than many portfolio loan products.
Conventional loans account for roughly 80% of all home mortgages originated in the United States, making them the most common financing option for San Diego homebuyers and refinancers. They offer a remarkable range of flexibility: you can finance primary residences, second homes, and investment properties; choose fixed or adjustable rates; and select terms from 10 to 30 years. Perhaps most importantly, conventional loans allow you to cancel private mortgage insurance (PMI) once you reach 20% equity — a significant advantage over FHA loans, which charge mortgage insurance for the life of the loan on most 30-year terms.
For San Diego buyers in 2026, conventional loans are especially attractive because the county's high-cost conforming loan limit of $1,104,000 covers the vast majority of transactions. Whether you're purchasing a starter condo in Mira Mesa, a family home in Scripps Ranch, or a multi-unit investment property in North Park, a conventional loan likely fits your price range without stepping into jumbo territory. The high conforming limit means you get access to the most competitive rates from the broadest pool of lenders — and as an independent mortgage broker, Cascada Mortgage Advisors, Inc. shops your loan across 50+ wholesale lenders to find the best combination of rate, fees, and terms.
Conventional loans also come in specialized low-down-payment flavors. Fannie Mae's HomeReady and Freddie Mac's Home Possible programs allow qualified first-time buyers to put down just 3%, with reduced PMI rates and flexible income sourcing that counts boarder income and non-borrower household income. When combined with California's down payment assistance programs (like CalHFA), San Diego buyers can often get into a home with less upfront cash than they expected.
For those with strong credit profiles (740+ FICO), conventional loans typically offer lower overall costs than FHA. The absence of an upfront mortgage insurance premium (FHA charges 1.75%) and the ability to cancel PMI mean that borrowers with good credit and moderate-to-strong down payments save tens of thousands of dollars over the life of the loan. Even with less than 20% down, PMI premiums for high-credit borrowers can be as low as 0.2–0.4% annually — significantly cheaper than FHA's fixed annual MIP rate.

Conventional Loan Pros and Cons

Your interest rate stays the same for the entire loan term (15, 20, or 30 years). Predictable monthly payments make budgeting simple. The most popular choice for San Diego homebuyers planning to stay long-term.
Adjustable-Rate Mortgage (ARM)
Start with a lower fixed rate for 5, 7, or 10 years, then adjusts annually based on market indexes. Great for buyers who plan to sell or refinance before the adjustment period.

Conventional Loans Across San Diego Neighborhoods
San Diego's diverse housing market means conventional loans work differently depending on where you're buying. With the 2025 median home price hovering around $900,000, the high-cost conforming limit of $1,149,825 covers the vast majority of purchases across the county.
In coastal communities like La Jolla, Del Mar, and Carmel Valley, median prices often approach or exceed the conforming limit. For these areas, buyers may want to explore putting more down to stay within conforming territory — the rate savings compared to a jumbo loan can be substantial. Alternatively, our jumbo loan program offers competitive rates for higher-priced properties.
Mid-range neighborhoods like Scripps Ranch, Rancho Peñasquitos, Tierrasanta, and Mira Mesa — with median prices in the $800K–$1M range — are the sweet spot for conventional financing. Buyers with 20% down avoid PMI entirely, and the loan amounts fall well within conforming limits for the best available rates.
For first-time buyers exploring more affordable areas like Chula Vista, El Cajon, Spring Valley, and National City (median prices $550K–$750K), conventional HomeReady and Home Possible programs with 3% down offer a compelling alternative to FHA — especially for borrowers with credit scores above 700. Check out our First-Time Homebuyer Guide for step-by-step guidance.
Investment-focused neighborhoods like City Heights, North Park, East Village, and Logan Heights offer strong rental yields on conventional investment property loans. The San Diego rental market remains exceptionally tight, with vacancy rates below 3% and median rents continuing to climb. Multi-unit properties (2–4 units) in these neighborhoods can be financed with conventional loans up to $2.2M.
