Most skip tracing starts with a list somebody else assembled, priced per record whether or not the records are any good. We started from the county rolls instead: every Florida parcel, keyed by owner, so the list is something you build rather than buy.
The outreach side came from the same frustration. Texting property owners is heavily regulated, and most tools leave the compliance to you. Here consent records, opt-out handling and quiet hours are enforced by the software, not left in a help article.
