Baltimore-Towson's eligible cohort is mid-sized at 80 operators, and share movement is dominated by SFR independents expanding listing volume rapidly. The one large institutional presence — Mission Rock Residential — shed roughly half its tracked listings year-over-year, a structurally meaningful contraction in a market where no other institutional scale is visible.

Share gains are concentrated entirely among SFR independents, with five operators each posting triple-digit percentage-point gains driven by listing-count doubles or near-doubles — Vita Zonis (+136.86pp, 210 listings), Sungate Property Management (+138.94pp, 153 listings), and True Property Management LLC (+137.58pp, 110 listings) are the largest by volume. Losses are broadly distributed across SFR independents and one institutional operator. East Coast Management Company LLC, Bay Property Management Group, and Mission Rock Residential each contracted sharply. The overall pattern reads as fragmentation with active churn: incumbents losing ground to a wave of mid-scale SFR independents.

The 7-cell quadrant data is not populated for this market in the current data pull — cell-level DOM, rent, and operator-count breakdowns are unavailable. Directionally, the operator list and share data show an SFR-independent-dominated market with minimal visible institutional or large MF/BTR presence. Mission Rock Residential is the sole large institutional name with meaningful listing volume (223 T12), and it is contracting. No other institutional operator appears in the gainer or loser cohorts.

Mission Rock Residential — a 10-market institutional operator also active in Phoenix, Knoxville, and Chattanooga — cut its Baltimore-Towson listing count by roughly half year-over-year, the sharpest absolute contraction in the cohort. Sungate Property Management appears in both the continuing gainer list and as a separate new-in-coverage entity, suggesting a possible entity split or rebranding worth monitoring. Statewide Management shows a similar pattern — a continuing-cohort loser alongside a new-in-coverage LLC variant with 95 listings — which may reflect operator restructuring rather than true market exit and entry.
