The Basics
What conventional loans are and how they differ from government-backed programs.
Conventional loans are mortgages that conform to guidelines set by Fannie Mae and Freddie Mac. Unlike FHA, VA, or USDA loans, conventional loans are not insured or guaranteed by the federal government. They offer flexibility for primary residences, second homes, and investment properties.
Key distinction: Conventional loans require private mortgage insurance (PMI) only until you reach 20% equity. Once you achieve 20% equity through payments or appreciation, PMI can be removed, reducing your monthly payment. FHA loans require mortgage insurance for the life of the loan if you put down less than 10%.
2026 San Diego County loan limits:
- Baseline conforming: $832,750 (nationwide standard)
- High-balance conforming: $1,104,000 (San Diego County high-cost area)
- Jumbo (non-conforming): $1,104,001+ (see Jumbo Loans)
How Conventional Loans Work
The qualification process and documentation requirements.
Conventional loans evaluate your credit score, income stability, debt-to-income ratio, and down payment capacity. Lenders verify income through pay stubs, W-2 forms, and tax returns. Self-employed borrowers provide two years of tax returns and profit/loss statements.
Down Payment Options
Available for first-time homebuyers through HomeReady and Home Possible programs. Requires PMI until 20% equity.
Standard minimum for repeat buyers purchasing primary residences. Requires PMI until 20% equity.
Eliminates PMI requirement and qualifies for best interest rates. Recommended for buyers with sufficient savings.
PMI Removal Process
Once you reach 20% equity (80% loan-to-value ratio), you can request PMI removal by contacting your lender and ordering an appraisal. If the appraisal confirms 20% equity, the lender removes PMI. PMI automatically terminates at 22% equity (78% LTV) without requiring borrower action.
Who Conventional Loans Are For
Borrower profiles that benefit most from conventional financing.
- First-time buyers with good credit: San Diego County buyers with 680+ credit scores who want 3% down payment options and removable PMI
- Repeat buyers with equity: Homeowners upgrading or relocating with equity from previous home sales to use as down payment
- Strong credit borrowers: Buyers with 740+ credit scores who qualify for best rates and lowest PMI costs

When Conventional Loans Don’t Fit
Situations where alternative programs may be better.
- Credit scores below 620: FHA loans accept credit scores as low as 580 (3.5% down) or 500 (10% down)
- Limited savings for down payment: VA loans offer zero down payment for eligible military service members and veterans
- High debt-to-income ratios: FHA loans allow DTI ratios up to 57% with compensating factors (conventional typically caps at 50%)
- Recent credit events: FHA waiting periods after bankruptcy or foreclosure are shorter than conventional requirements
- Self-employed with complex income: Bank statement or profit/loss non-QM loans may be easier than conventional full documentation

Common Use Cases in San Diego County
These are scenario patterns — not promises, not timelines, not guarantees.
Scenario 1: First-Time Buyer in Chula Vista
A first-time homebuyer in Chula Vista qualifies for a 3% down payment conventional loan through the HomeReady program. They purchase a $650,000 property with $19,500 down (3%) and finance $630,500. With a 680 credit score, they pay PMI monthly. After several years of payments and property appreciation, they reach 20% equity and request PMI removal, reducing their monthly payment by approximately $250.
Scenario 2: Move-Up Buyer in Carlsbad
A San Diego County homeowner sells their current property and uses $150,000 in proceeds as a down payment on a $900,000 home in Carlsbad. With 16.7% down, they finance $750,000 and pay PMI. Their 750 credit score qualifies them for competitive rates. Within two years, property appreciation brings them to 20% equity, and they request PMI removal.
Scenario 3: High-Balance Loan in La Jolla
A buyer purchasing a $1,050,000 property in La Jolla requires financing above the baseline conforming limit ($832,750) but below the San Diego County high-balance limit ($1,104,000). They put 20% down ($210,000) and finance $840,000 with a high-balance conventional loan. They avoid PMI and secure competitive terms without entering jumbo loan territory.
