How to use this
What is this page?+
A public ledger of every investor purchase recorded in ZIP 21771 over the last 24 months, built from Maryland SDAT public records and refreshed nightly. It answers one question: who's buying in your backyard, and what are they paying.
What counts as an investor buy?+
An arms-length transfer with real consideration where SDAT's owner-occupancy code says the new owner does not live there. Owner-occupant purchases, gifts, foreclosures and family transfers are excluded.
Why are some buyers unnamed?+
Maryland's free statewide dataset hides owner names but publishes the owner's mailing address, so the Ledger groups purchases by that address. Baltimore City names are public. Open any buyer to reveal the name behind the group.
How do I use this to sell a deal?+
Open ZIP 21771 in the Ledger, filter to the asset class and recency that match your deal, then use Match a Deal to rank the buyers who already bought that kind of property nearby. Sync them to GoHighLevel or export a CSV.
