Florida Tax Certificate API
Florida Certificate Holder Search — Liens by Investor & Fund
See every Florida tax certificate tied to an investor or fund in one query. Holder search ranks across holder/fund name, certificate number, county, and parcel — useful for certificate-holder due diligence, portfolio tracking, and competitive research. Holder data is drawn from the public certificate-sale records and grows as each vendor portal is onboarded; we label coverage honestly per county.
