Liens that survive

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.

Verify before you bid

This record was compiled from the published sale list. Parcels are pulled, redeemed, and re-priced up to the moment of sale. Confirm the lot is still in the sale, and confirm the opening bid, directly with the county.

p(redeem) prior

12%

History n=614: median sold $3,853 is well below oracle $584,973 — target ~82% of ceiling.

Your assumptions

After-repair value (ARV)

Override the derived estimate with real comps

Rehab budget

You cannot inspect before bidding — budget for the worst plausible condition

Known surviving liens

Municipal code enforcement, special assessments, federal tax liens

Target margin — 30%

Required profit as a share of ARV. 30% is a common floor for tax-sale flips.

How that number is built

Provider market estimate of $978,000. This is an as-is valuation, not an after-repair one — enter your own comparable-sales figure if the property needs work.

After-repair value: $978,000
Selling costs on exitassumed 8.0% of ARV — agent commission plus seller-side closing.: −$78,240
Rehabassumed No rehab budget entered — assumed $0. Tax-sale parcels are sold unseen and un-inspected; this is rarely correct.: −$0
Quiet title (required)assumed Midpoint of the typical CA range ($3,000–$7,000, ~9 months).: −$5,000
Deed recording and transferassumed Typical CA recording and deed issuance cost.: −$250
Holding costs (11 months)assumed Taxes, insurance, and securing the property at ~$1,467/month.: −$16,137
Surviving liensassumed Assumed $0 — not verified. Municipal code-enforcement liens, special assessments, and federal tax liens can survive the sale.: −$0
Target profit (30% of ARV): −$293,400
Maximum bid: $584,973

Before you bid

Rehab is assumed to be $0. You cannot inspect these properties before bidding — budget for the worst plausible condition.
Surviving liens assumed $0. No post-sale redemption. The owner's right ends at 5pm on the last business day before the sale, so the deed conveys without that overhang.
California assesses at full cash value, but Proposition 13 fixes the base year and factors it forward at up to 2%/yr. On a long-held parcel the assessed value can sit far below market, so an ARV derived from it understates the property — get comparable sales before bidding.
