Cobb County's underwriting tension is a soft price signal against a positive rent screen. Zillow's county median home value is $429,051, down 2.46% year over year; median asking rent is $1,752, up 0.93%. The published gross yield is 4.90% before costs. That favors income underwriting, while investors relying on appreciation or assuming rent growth should be cautious; the record does not establish a countywide thesis.
Market rent and HUD FMR must remain separate: the published rent is a median asking-rent measure, while the two-bedroom FMR is $1,820, a payment standard rather than an asking-rent estimate; their ratio is 96.30%. The effective property-tax rate is 0.67%, adding carrying cost before insurance, maintenance, vacancy, management, financing, or flood coverage. FHFA's separate repeat-transaction HPI rose 2.10% and gained 60.90% cumulatively. That index supports positive appreciation in its own vintage, but is not a home value and must not be averaged with Zillow's observation.
Realtor.com MLS evidence shows active listings up 6.25% and 24.10% of listings price-reduced. Those are visible-supply and seller-concession signals, not closed-sale prices or proof of buyer demand; the pending ratio and marketing time should be checked at property level. QCEW's annual county record shows covered employment down 0.70% while average weekly wage rose 2.41%. The largest disclosed private supersector is Trade, transportation, and utilities; neither its employment concentration nor QCEW covers resident employment or the whole metro economy.
Demand evidence is mixed: net migration is -1,303, and the AGI gap is -$6,446, so average income among movers out exceeded movers in; check household and lease-up demand rather than treating population scale as momentum. Investors made 839 of 8,956 purchase mortgages, or 9.37%, a participation measure but not proof of buyer competition or rental demand. Inland flood is the dominant hazard; the modeled annual building-loss ratio is 0.11%. Obtain parcel-level flood maps, elevation, insurance and deductible quotes, claims history, operating expenses, vacancy, and financing terms. Without those, gross yield cannot become a net-return conclusion, and county evidence cannot establish metro representativeness.
