LienHarbor started as a spreadsheet. Shea Mentges buys tax lien certificates himself, and got tired of tracking rates, maturity dates, and a folder of scanned county documents by hand — so he built the tool he actually needed, and is opening the harbor to every other investor doing the same thing.
Portfolio, in one view
Every certificate, its rate, and its return, tracked in one place — not scattered across a spreadsheet and a folder of county paperwork.
A statement your bank will take
Generate a holdings report for your certificates — illiquid, sure, but about as close to guaranteed as an asset gets.
AI does the data entry
Upload a scanned list, a PDF, or a photo of a sale sheet. LienHarbor reads it and fills in the records for you.
