Maryland files failure-to-pay-rent cases in District Court, and Baltimore City generates one of the highest per-capita filing volumes in the country. Because a filing becomes a public court record whether or not you lost the case — and whether or not you paid before the hearing — tenant screening companies routinely surface cases that never resulted in a judgment against you. Maryland's HOME Act also made source of income a protected class statewide, so a landlord cannot refuse you solely for paying with a voucher. That protection does not extend to credit scores or filing history, which is where most Baltimore denials actually happen.
That is the gap this program is built for. Nothing about your record changes — instead, your record stops being the thing under review. When the applicant on the lease is a company with its own credit file and lease references, the automated screen that would have rejected you never runs against your name.
