The counts on this page are free and update daily. The address-level list — every pre-foreclosure, auction and bank-owned home in Petaluma with the owner of record, open loans, liens and an equity estimate — is inside Properant, which starts with a free trial. Foreclosure filings are public record, so you can also read them one at a time at the Sonoma County recorder; Properant simply links all of them to their properties statewide.

It depends on the stage. Homes at foreclosure auction (3 scheduled in Petaluma right now) are sold to the highest cash bidder, and anyone can bid. Bank-owned homes (53 in Petaluma) belong to the lender and usually list with a real-estate agent after the sale. Pre-foreclosure homes (18) are not on the market yet — their owners still hold title, which is why investors approach them directly before the auction. Properant tracks every stage daily, with the owner, open loans and equity behind each address.

A pre-foreclosure begins when the lender records a notice of default with the Sonoma County recorder; roughly three months later a notice of trustee sale can follow, which sets the auction. Both are public documents. Properant reads every filing as it is recorded, removes the ones that were cured or cancelled, and shows the 18 that are live in Petaluma today on the map, filterable by stage, equity, absentee owner and more.

Most California foreclosures are non-judicial trustee sales: after the notice of default period, the trustee records a notice of sale with the date, time and place, and the property is auctioned to the highest cash bidder (the lender's opening bid is typically the debt owed). Sales are frequently postponed at the podium. Petaluma currently has 3 auctions scheduled; each one in Properant carries the sale date, published opening bid, the trustee, and the owner and loan history behind it.

Petaluma currently shows 278 properties with delinquent property taxes on Sonoma County records. Nothing about tax delinquency is public-facing — no filing, no sign — but five years of it makes a property eligible for the county tax-deed sale, and owners on this list disproportionately hold real equity with a cash-flow problem a sale would solve.

Yes. Notices of default, notices of trustee sale and trustee's deeds are recorded with the county recorder and are public record; tax-delinquency status is on the county tax roll. What is hard is reading them at scale — hundreds of filings a day across 58 counties — which is the part Properant does, updated daily.
