Chattanooga's rental market is fragmenting under rent pressure: -3.17% T12 rent growth accompanies a wave of new SFR entrants displacing incumbent operators. The continuing cohort is small (27 operators), so share swings are amplified, but the directional story — institutional MF gaining on SFR independents — is structurally legible.

Mission Rock Residential dominates the gainer column with +93.19pp share, driven by near-doubling of its listing count (122 to 240) — the clearest consolidation signal in the dataset. Four SFR independents (H&H, Link, Ampere, AVS) also gained meaningfully, suggesting the SFR segment is not uniformly retreating. The loser side is concentrated among SFR independents: Tahini South Broad (Large MF/BTR Independent) is the outlier, shedding roughly half its prior listing volume. Auben Realty, Gig City, HomeRiver, and The Real Estate Mavericks collectively shed significant share. Five new SFR independents entered coverage above the 20-listing threshold, further pressuring incumbents.

The 7-cell quadrant data carries no per-cell metrics in this pull — DOM and rent figures are unpopulated across all six reported cells — so operator-mix characterization relies on taxonomy counts alone. The active operator base (152 operators, 49 eligible for cohort) skews heavily toward SFR Independent by both operator count and new-entrant composition. The sole institutional MF presence with measurable share movement is Mission Rock Residential. Hybrid representation is thin. This is a market where SFR independent operators collectively set the structural tone, with one large institutional MF operator punching disproportionately above its weight.

Mission Rock Residential is the lead signal: a 10-market national platform also active in Phoenix and Knoxville, it nearly doubled Chattanooga listings YoY — the kind of purposeful scaling that warrants monitoring across its full footprint. Generation Property Management (135 T12 listings, new in coverage) and Doorby Property Management (105 listings, new in coverage) are the largest SFR entrants, together adding material supply-side volume. Tahini South Broad LLC warrants attention as the sharpest volume-absolute loser: 126 to 62 listings in a softening rent environment suggests operational contraction, not just share dilution.
