Tax-default investing, without the busywork.

California’s tax-defaulted property auctions are one of the last corners of real estate where a diligent investor can still find real value. But the information is a mess: 58 counties, each with its own site, its own schedule, and a bare list of parcel numbers and minimum bids. Finding the opportunities — and doing the homework to bid with confidence — means hours of hunting across county portals and assessor records.

Trelys was built to remove that friction. We aggregate every county’s auctions as their schedules publish, enrich each parcel with public assessor and GIS data, put it all on a searchable map, and hand you the tools to model a deal before you bid — so you can spend your time on decisions, not data entry.

We’re expanding county by county, and we’re transparent about what each county provides. Everything we surface comes from public records — county tax collectors, assessor rolls, and GIS services.
