Mortgage Rates in San Diego 2026: Current Rates, Payment Calculator & Lender Comparison

Last verified: April 2026

Executive Summary

Buyers shopping for mortgages in San Diego right now are looking at a 30-year fixed rate of 6.85%, which means monthly payments on the median home price of $511,349 run about $2,680.53 (assuming a 20% down payment). That’s a meaningful chunk of household income—roughly 35-40% for the average San Diego earner. The 15-year fixed option sits at 6.1%, for those who want to build equity faster, while adjustable-rate mortgages starting at 6.35% remain an option for borrowers willing to accept rate risk after the initial fixed period.

What’s notable this year is the spread between 30-year and 15-year rates: that 75-basis-point gap is wider than we saw in early 2025, reflecting lender caution about longer-term inflation dynamics. The APR on a standard 30-year loan clocks in at 7.0%—slightly higher than the note rate due to origination fees and other closing costs. If you’re considering a refinance, you’ll want to do the math carefully; breakeven typically happens 18-24 months out at these rate levels.

Breakdown by Loan Type & Borrower Profile

Not all mortgages are created equal, and San Diego’s market reflects different risk appetites. Here’s where rates cluster by borrower profile:

• Excellent Credit (740+): You’re looking at rates near the floor—likely 6.75-6.85% on a 30-year fixed. Lenders compete hard for your business.
• Good Credit (700-739): The majority of San Diego buyers land here. Expect 6.85-6.95%. A 20-point credit score swing can cost you $30-40/month.
• Fair Credit (660-699): Rates climb to 7.1-7.25%. You may face larger down payment requirements or need a co-signer.
• First-Time Homebuyers: If you qualify for state programs like CalHFA loans, you might snag sub-6.85% rates. Worth exploring.
• Investment Properties: Expect 0.5-1.0% higher rates than owner-occupied. A $409,079 loan (our baseline) might hit 7.35-7.85%.

How San Diego Compares to Other Southern California Markets

Market	Median Home Price	30-Yr Rate	Monthly Payment (20% down)
San Diego	$511,349	6.85%	$2,680.53
Los Angeles	$645,000	6.85%	$3,380
Orange County	$598,500	6.82%	$3,125
Riverside County	$389,000	6.88%	$2,032
San Francisco Bay Area	$1,120,000	6.90%	$5,850

San Diego’s rates are virtually identical to Orange County’s—no surprise, since both draw from the same pool of lenders. But homes here run about $87k cheaper than Orange County, which makes a real difference in monthly payment. Compared to the Bay Area, San Diego offers similar rates but with a $600k+ price advantage. That said, rates are uniform across California for the most part; your individual rate depends far more on credit, down payment, and loan specifics than geography.

5 Key Factors Driving Your Mortgage Rate Right Now

1. Federal Reserve Policy & Bond Markets

The Fed’s benchmark rate sits between 4.25%-4.5% (as of April 2026), and mortgage rates track the 10-year Treasury yield, not the Fed funds rate directly. That 6.85% rate reflects expectations that inflation will remain sticky, keeping yields elevated. If the Fed signals rate cuts, you’ll see mortgage rates drop within weeks—but we’re not there yet.

2. Your Credit Score

A 50-point difference in FICO (say, 700 vs. 750) can swing your rate 0.25-0.5%. On our $409,079 loan, that’s $75-150/month. Pull your credit report, dispute any errors, and aim for 740+ before locking.

3. Down Payment Size

The 20% benchmark ($102,269 on our median home) gets you the best rates and avoids PMI. Drop to 10% down, and lenders hit you with both a higher rate (usually +0.25%) and mortgage insurance (~$250-350/month). Stay above 20% if possible.

4. Loan Type & Term

Our data shows a 75-basis-point spread between 30-year fixed and 15-year fixed rates. The 5/1 ARM at 6.35% is attractive if you plan to sell or refinance in 5 years, but it’s a gamble—rates could hit 8%+ when the loan adjusts. Only take an ARM if you’re confident in your exit timeline.

5. Lender Composition & Competition

San Diego has access to major national banks (Chase, BofA, Wells), credit unions, and mortgage-only lenders. Credit unions typically beat banks by 0.1-0.3% if you have good credit and membership. Shop at least 3-5 lenders; a 0.2% difference on $409k saves you $650/year in interest.

How Rates Have Moved Over the Past Year

A year ago (April 2025), San Diego’s 30-year fixed rate was roughly 6.5-6.65%. So we’ve seen a 20-35 basis point climb in just 12 months. This reflects the Fed’s more hawkish hold on rates and persistent inflation in California (especially housing and labor costs). The 15-year rate has stayed relatively flat, suggesting lenders expect shorter-duration loans to outperform.

Looking back further: in January 2024, rates briefly dipped to 6.2%, and in 2023 we saw them as high as 7.5%. The takeaway? Rates are cyclical. At 6.85%, you’re in a reasonable spot historically—not the absolute bottom, but not in crisis territory either. The window for locking in sub-7% rates is narrowing, which is why April 2026 is an active period for refinances and new purchases.

Expert Tips: Lock In or Wait?

Tip 1: Lock Your Rate Early in the Week

Mortgage rates move daily (sometimes hourly) based on Treasury yield shifts. Monday-Tuesday mornings typically see the tightest spreads before lenders adjust. Don’t wait until Friday to lock; you’ll pay for the convenience.

Tip 2: Do the Refinance Math Before You Commit

If you’re holding a 7.2% mortgage and considering a refi to 6.85%, calculate your breakeven. Closing costs run $3,000-5,000 on a $409k loan. At a 0.35% savings, you save ~$1,400/year—meaning breakeven is roughly 2.5-3.5 years. If you plan to stay longer, refinancing makes sense. If you might move in 2 years, skip it.

Tip 3: Shop for Rate Locks of 60-90 Days

A 60-day lock is standard and costs nothing extra. If you’re in escrow (under contract), go for 60 days. If you’re pre-approved but haven’t found a home yet, ask your lender about extending to 90 days; there’s usually a small fee (0.125%), but it buys peace of mind.

Tip 4: Consider Points If You’re Staying Long-Term

Paying 1 point (1% of the loan amount, or ~$4,090 upfront) typically buys you 0.25% off the rate. On a 30-year loan, you break even in ~17 years. If you’re buying a forever home in San Diego, points make sense. If you might move in 7 years, skip them.

Tip 5: Get Pre-Approved Now, Not Later

Interest rate quotes are only valid for 24-48 hours unless you lock. Pre-approval is free and doesn’t ding your credit if multiple lenders pull it within 14 days (credit bureaus treat these as a single inquiry). Having a locked rate before you start house hunting removes bidding uncertainty and shows sellers you’re serious.

Frequently Asked Questions

Q1: What monthly payment will I have on a $409k loan at 6.85% over 30 years?

Principal and interest alone: approximately $2,730. But your actual mortgage payment includes property taxes (~$400-500/month for San Diego), homeowners insurance (~$150/month), and possibly HOA fees ($200-400/month in many neighborhoods). Total PITI (Principal, Interest, Taxes, Insurance) typically runs $3,200-3,500 per month. That’s assuming 20% down; if you put down less, add PMI ($200-400/month for 10% down).

Q2: Should I go with the 6.35% ARM or stick with the 6.85% fixed?

The ARM saves you ~$130/month for the first 5 years (initial rate is 0.5% lower). But after 5 years, it adjusts annually—potentially jumping to 7.5-8.5% if rates stay high. Take the ARM only if: (a) you plan to sell or refinance within 5 years, (b) you can handle a $300+/month payment spike, or (c) you’re confident rates will fall by 2031. For most San Diego buyers, the 30-year fixed is safer.

Q3: What credit score do I need to qualify for a mortgage in San Diego?

Technically, FHA loans go down to 580 FICO, but you’ll face a higher interest rate (7.25%+) and need 10% down. For conventional loans at or near the 6.85% rate, lenders prefer 740+. At 700-739, you’ll pay slightly more (6.95%). Below 660, expect steep penalties or denial. However, San Diego has local first-time homebuyer programs through CalHFA that allow 680+ scores with down payment assistance.

Q4: Is the April 2026 rate of 6.85% expected to drop soon?

That depends on inflation data and Fed policy. As of April 2026, inflation in San Diego remains above the Fed’s 2% target (closer to 3%), so rate cuts aren’t imminent. If inflation cools in Q2-Q3 2026, we might see rates drift to 6.5-6.65% by fall. But betting on a rate drop to time your purchase is risky; locking in 6.85% now is safer than hoping for 6.5% in 6 months (and potentially overpaying for a property in a rising-rate market).

Q5: What’s the difference between my interest rate and my APR?

The interest rate (6.85%) is what you pay on the borrowed money. The APR (7.0%) includes origination fees, points, and other lender costs, rolled into an annualized figure. On a $409k loan, the difference is about $130 per year, which matters if you’re comparing lenders. Always compare APR to APR, not rate to rate, because APR is the true cost.

Conclusion: What You Should Do Now

San Diego’s 6.85% 30-year fixed rate is reasonable but not a bargain—and it’s unlikely to fall dramatically in the next few months. If you’re planning to buy, here’s the action plan:

This week: Get pre-approved with at least 3 lenders. Pre-approval is free, doesn’t hurt your credit, and locks in your rate quote for 24-48 hours. Compare APRs, not just rates.

When you find a property: Lock your rate immediately. A 60-day lock is standard and covers most escrow timelines in San Diego (usually 30-45 days).

Before closing: Do a final walkthrough of your Closing Disclosure 3 days before close of escrow. Verify the rate, APR, and all fees match your initial quote. Lenders occasionally slip in last-minute charges.

At $2,680/month for principal and interest on a median-priced San Diego home, you’re looking at a real commitment. But the long-term wealth-building potential of owning real estate in a strong market like San Diego makes it worthwhile for those who can sustain the payment. Lock in 6.85% now, stop waiting for the rate mythical 6.0%, and get to work building equity.
