A lien search is a photo. Your portfolio is a movie.
A lien search tells you exactly one thing: what was on file the day you ran it. It's accurate, it's useful, and it starts going stale the moment the report is delivered.
A snapshot in a moving record
County recorders, courts, and state filing offices process new documents every business day. A clean search on Monday says nothing about a mechanic's lien recorded on Tuesday or a judgment docketed next month.
For a single acquisition, that gap is manageable. For a portfolio of hundreds of loans or assets, held for years, it becomes the main source of blind risk.
What slips through
The filings that matter most tend to arrive after the search: involuntary liens from contractors, tax authorities, or judgment creditors; new mortgages recorded against a property you already lend on; lis pendens signaling a lawsuit that affects title; ownership transfers that change who you're actually exposed to; and UCC filings against the entities behind the deal.
Each one can change the risk profile of a deal. None of them show up in a report you ran last year.
Rerunning searches doesn't scale
The obvious fix is to search more often. In practice, that means paying for repeated reports, assigning analysts to review them, and still only catching filings at whatever interval you can afford. Quarterly is expensive. Monthly is rare. Continuous is impossible by hand.
From snapshot to live feed
The answer isn't more searches. It's monitoring. Alefy watches the public record for every property and entity in your portfolio and surfaces new filings as they appear. A lien search tells you where things stood. Alefy tells you what just changed.
