Southern California houses nearly half of California’s equity-millionaire homeowners, with 540,000 mortgage-holders holding seven-figure equity stakes as regional property values continue a decade-long climb, according to Intercontinental Exchange data.
The regional distribution is calculated as follows. The five Southern California counties account for 540,000 equity millionaires:
- Los Angeles: 218,489
- Orange: 188,301
- San Diego: 119,057
- Riverside: 8,977
- San Bernardino: 5,182
- Record Wealth: U.S. mortgaged homeowners hold $17.5 trillion in total equity, with California accounting for $4.7 trillion of that total.
- Decade Gains: Median home prices across California surged 74% over the last ten years, led by Orange County’s 100% appreciation, according to the California Association of Realtors.
- Tax Relief Watch: The pending More Homes on the Market Act could double capital gains tax exemptions to $1 million for married couples, potentially unlocking home equity.
The accumulation of $1 million or more in equity stems from down payments, standard amortization schedules, and long-term property appreciation. Leverage allows buyers to control a major asset with a fraction of their own capital. When a property appreciates, the resulting equity gain applies to the entire new market value rather than just the initial down payment.
Consider the trajectory of median home prices over the decade ending September 2026, as reported by the California Association of Realtors. Statewide median prices reached $899,720 compared to $516,450 a decade prior, representing an increase of 74%.
| County | September 2026 Median | September 2016 Median | 10-Year Increase |
|---|---|---|---|
| Orange County | $1,480,000 | $739,000 | 100% |
| San Bernardino County | $531,090 | $251,750 | 110% |
| Los Angeles County | $994,670 | $550,705 | 81% |
| San Diego County | $1,050,000 | $569,000 | 84% |
| Riverside County | $620,000 | $352,250 | 76% |
Homeowners seeking to tap accumulated equity face shifting federal borrowing costs alongside potential tax relief. The 30-year fixed mortgage rate averaged 7.11%, dropping 7 basis points week-over-week, while the 15-year fixed rate averaged 6.45%, according to Freddie Mac data. Mortgage application volume rose 6.2% compared to the prior week, the Mortgage Bankers Association reported.
Meanwhile, federal legislation could alter selling incentives for equity-rich owners. The More Homes on the Market Act (H.R.1340 and S.3332) has drawn 159 House co-sponsors and 25 Senate co-sponsors, according to Congress.gov. The bill would double the capital gains tax exemption to $1 million for married joint filers, requiring two years of primary residence ownership.
“For current homeowners who have enjoyed massive appreciation and have thought about selling to move up, down or out of town, opportunity may be knocking soon,” said Jeff Lazerson, president of Mortgage Grader. Whether the legislative package clears Congress remains undetermined as market participants monitor inventory levels and prevailing interest rates.
