San Diego County is preparing to auction 686 tax-defaulted properties from May 8-13, 2026, potentially generating over $18 million in tax revenue. If you're a homeowner facing this auction or an investor seeking acquisition opportunities, the April 30, 2026 bidder registration deadline (5:00 PM) is fast approaching.

The auction includes 70 improved homes, 66 unimproved lots, and 550 timeshares across all San Diego County areas—from Pacific Beach and La Jolla to North Park and Mission Valley. These properties have been in tax default for at least five years, according to the San Diego County Treasurer-Tax Collector.

Critical fact for homeowners: You can still sell your property before auction to preserve equity and avoid the public sale process.

How the May 2026 Tax Auction Works

The online auction runs through sdttc.mytaxsale.com with strict requirements:

Registration deadline: April 30, 2026 at 5:00 PM

Required deposit: $1,000 (refundable) plus $35 non-refundable processing fee

Auction dates: May 8-13, 2026

Payment deadline: Full purchase price due within 5 business days of auction close

According to FOX 11 Los Angeles, properties in tax default for five or more years become subject to the county tax collector's power to sell. Properties range from residential homes in neighborhoods like Mission Beach and Point Loma to vacant lots throughout San Diego County.

For Homeowners: Sell Before Auction to Protect Your Future

If your property is heading to the May auction, selling to a cash buyer before April 30 offers significant advantages:

Preserve your equity

Auction properties often sell below market value with all proceeds going to back taxes and fees. Selling directly lets you keep any remaining equity.

Avoid public embarrassment

Tax auctions are public records. A private cash sale protects your privacy.

Faster, guaranteed outcome

Cash buyers can close in 7-14 days with certainty, versus the unpredictable auction process.

No credit impact—but you still lose the property

While tax liens no longer directly affect credit scores as of 2018 (when credit bureaus stopped reporting them), losing your home to auction means you walk away with nothing if there's no equity after taxes are paid.

The San Diego County property tax sale process gives owners until the auction date to redeem their property by paying all taxes and fees—but for many homeowners in five-year default, that's financially impossible. A cash sale is often the only realistic path forward.
