Five-Year San Diego Housing Market Data
San Diego Single-Family Home Prices: 2021 to 2026
San Diego County's single-family home market has undergone a dramatic transformation over the past five years — from a pandemic-fueled frenzy with 7-day sales and sub-$900K medians, to a rate-constrained market hovering above $1.1 million. Understanding this arc is the foundation for any serious buying strategy in 2026.

Mortgage Rate History: 2021 to 2026
When mortgage rates rise, price growth stalls. When rates fall, prices surge. This is more pronounced in San Diego than most markets because local supply cannot expand — the county is bounded by ocean, mountains, Mexico, and Camp Pendleton.

Days on Market & Months Supply: 2021 to 2026
Days on market dropped to just 7 days in 2021. By April 2026 that figure has risen to 35 days, giving buyers more time than at any point in five years. Months supply remains at 2.3 months — still firmly a seller's market, but the most balanced it has been since 2019.

Why San Diego Home Prices Don't Crash
Unlike many U.S. metros, San Diego home prices have never experienced a sustained multi-year decline. The reason is structural: the county cannot build its way out of a supply deficit. Geographic constraints on all four sides mean that when demand drops, inventory also drops as sellers stay put rather than accept lower prices. The 2022–2023 correction was a 3% dip followed by a fast recovery to new highs. Being ready to act is more important than waiting for a perfect moment.
Interest Rate Analysis — 2025 to 2026
Fed Funds Rate, 10-Year Treasury Yield & 30-Year Mortgage Rates in 2026
Three interest rates drive the San Diego housing market: the Federal Reserve's benchmark rate, the 10-year Treasury yield, and the 30-year fixed mortgage rate. Understanding how these interact is essential for any buyer in 2026.
The Federal Reserve Rate Path: From 5.5% Peak to 3.75% Hold
The Fed raised its benchmark rate from near zero in 2022 to a peak of 5.25%–5.50% by mid-2023. After holding for over a year, the FOMC cut rates by a total of 175 basis points in late 2024. The current target of 3.50%–3.75% has been held steady since December 2025. An unusual 8–4 vote at the April 29, 2026 meeting revealed deep internal disagreement, with four hawkish members signaling potential rate hikes if Iran-war inflation persists.
The 10-Year Treasury Yield: The Real Mortgage Driver
Mortgage rates do not directly follow the Fed funds rate — they follow the 10-year Treasury yield. In 2026 this distinction is critically important: even as the Fed held its benchmark steady, the 10-year yield rose from 4.21% in January to 4.57% in May, driven by Iran-war oil price inflation. The spread between the Fed funds rate and the 10-year yield reflects the market's expectation that rate cuts are off the table for now.
30-Year Fixed Mortgage Rates in 2026: The War's Fingerprint
The 30-year fixed mortgage rate entered 2026 at 5.98% — the lowest since 2022. That window was shattered when the Iran conflict erupted in late February. By May 21, 2026, the rate climbed to 6.51% per Freddie Mac PMMS — adding approximately $283 per month to the payment on a $1.1M San Diego home.

"The 30-year mortgage rate is not set by the Fed — it is set by the bond market's fear of inflation. As long as the Iran conflict keeps oil prices elevated, mortgage rates will remain higher than they otherwise would be. A ceasefire is the most powerful rate catalyst on the horizon."
Geopolitical Market Impact
How the U.S.–Iran War Has Affected San Diego Home Prices & Mortgage Rates
The U.S.–Iran military conflict that began in late February 2026 has had a measurable and direct impact on San Diego's housing market: conflict → oil disruption → inflation → higher Treasury yields → higher mortgage rates → reduced buyer purchasing power.

Strategic Buyer Analysis
The Post-War Buying Opportunity: Why Prepared San Diego Buyers Win
Every major geopolitical event that temporarily suppressed mortgage rates has been followed by a sharp rebound in buyer demand when it resolved. San Diego's structural supply deficit makes the price response likely to be faster and sharper than in most other markets.
Monthly Payment at Key Rate Scenarios: $1.1M San Diego Home
On a $1,100,000 home with 20% down ($880,000 loan), here is what your monthly principal and interest payment looks like at four rate scenarios — from today's war-elevated rate to a post-ceasefire recovery.
Monthly P&I Payment — $880K Loan, 30-Year Fixed
P&I only. Excludes taxes, insurance, HOA.
Assumes $1.1M purchase price, 20% down payment ($220K), $880K loan, 30-year fixed amortization.
Rate vs. Price: Which Costs You More?
A 1-point rate drop (6.5% to 5.5%) saves $565 per month — and that savings can be captured anytime through refinancing. A 10% price increase while you wait costs $575 per month permanently. The math strongly favors buying at today's prices and refinancing later over waiting for rates to fall and competing against a flood of returning buyers.
Rate drops 1 pt to 5.5%
$6,780 saved per year — refinanceable anytime
Price rises 10% if you wait
$6,900 more/yr — permanent, cannot be refinanced
The Historical Pattern: Rate Drops Trigger San Diego Price Surges
When the 30-year rate dropped from 7.79% in October 2023 to 6.61% by year-end 2024, San Diego prices jumped from $870,000 to over $1,000,000 — a 17% gain in approximately 18 months. When rates dropped during COVID-19 in 2020–2021, San Diego prices surged over 25% in a single year. Buyers who act early in the rate-drop cycle capture the most equity.
Frequently Asked Questions
San Diego Housing Market FAQ: 2026 Buyer Questions Answered
The questions San Diego buyers are asking most frequently right now. Click any question to expand the answer.
As of April 2026, the median sale price for a detached single-family home in San Diego County is $1,100,000, a 2.3% year-over-year increase per SDAR. This compares to $840,000 in 2021 — a 31% increase over five years despite periods of elevated mortgage rates.
The U.S.–Iran conflict beginning late February 2026 disrupted the Strait of Hormuz, spiked oil prices, and drove the 10-year Treasury yield near 16-month highs. The 30-year fixed mortgage rate rose from a pre-war low of 5.99% to 6.51% as of May 21, 2026 — adding approximately $283 per month to the payment on a $1.1M San Diego home.
The current market — 35 days on market and 2.3 months of inventory — gives buyers more preparation time than at any point since 2020. When the Iran conflict resolves and rates drop, pent-up buyer demand will flood back simultaneously against limited supply. Buyers who complete pre-approval and tour homes now will be positioned to act within 24–48 hours of a rate drop, before competition intensifies.
As of May 21, 2026, the 30-year fixed mortgage rate is 6.51% per Freddie Mac PMMS, up from a 2026 low of 5.98% in January. Fannie Mae projects 6.3% through year-end if the conflict persists, or approximately 5.9% if a ceasefire is reached.
As of April 2026, the median days on market is approximately 35 days, up 9.4% year-over-year. This compares to just 7 days in 2021. The increase reflects the dampening effect of higher mortgage rates on buyer urgency, not a fundamental softening of demand.
A ceasefire would likely push the 30-year rate below 6.2% within weeks. Historical precedent shows San Diego prices respond sharply to rate relief: the 2023–2024 rate drop triggered a 17% price gain. With 2.3 months of inventory and significant pent-up demand, a post-ceasefire rate drop could produce similar dynamics quickly.
No. The 30-year mortgage rate is primarily driven by the 10-year Treasury yield, not the Fed funds rate. This is why mortgage rates rose sharply in 2026 even while the Fed held its benchmark rate unchanged — the bond market was responding to Iran-war-driven inflation fears, not to Fed policy.
