Title risk

Liens that survive the sale

A California tax deed conveys free of most liens existing before the sale, but federal tax liens survive (the IRS keeps a 120-day post-sale redemption right), as do taxes/assessments that become payable after the sale.

Quiet title

Not a statutory prerequisite, but practically required — most title insurers in California won't insure a tax-deed property without a completed quiet title action (commonly 3-6 months, $3,000-$8,000+ in legal fees), and many won't insure until a year after the deed is recorded.

Cal. Rev. & Tax. Code § 401: property is assessed at full cash value, so the statutory ratio is 1.0.
