Walthall County is a valuation-verification case, not yet a demonstrated income case. Zillow’s county median home value was $157,654 in 2026-06, down 0.55% year over year, whereas FHFA’s repeat-transaction HPI increased 7.72% in 2025. The measures and labeled periods differ: Zillow is a value estimate and FHFA is an index of repeat transactions, not a home value. They should not be averaged or treated as one appreciation interval. Buy-and-hold underwriters should investigate the divergence; anyone requiring documented rent coverage should remain cautious.
Carrying costs are only partly visible. The effective property-tax rate is 0.72%, a known burden to test against the value estimate, but insurance, maintenance, financing, and parcel-specific taxes are not published. No county market asking rent is published, so gross yield cannot be computed. HUD FMR is $923 per month; it is a payment standard rather than an asking-rent estimate and cannot fill the rent gap. The price-to-rent relationship and any cash-flow conclusion therefore remain untested.
Workplace and buyer evidence is mixed but limited. QCEW reports 2,291 annual average covered jobs at county workplaces; this is neither resident employment, unemployment nor a forecast. Realtor.com MLS evidence shows 40 active listings, up 81.82% year over year. That measures visible asking-market supply, not closed-sale pricing or buyer demand, and requires inspection of the individual competing listings. Tax-return migration was negative by 13, while incoming movers’ average AGI was $1,960 below that of outgoing movers. The record counts 6 investor purchases among 105 total purchases, or 5.71%, an observed participation share rather than a measure of all local buyers.
Modeled annual climate loss is 0.16% of building value and aligns with inland flood as the dominant hazard, but it is not a parcel-level loss estimate. The central next checks are actual lease comps, executed sale comps, flood zone and elevation, insurance quotes, property condition, and title-specific tax bills. Their absence prevents a defensible gross-yield, resale-value, hazard-cost, or stabilized-expense conclusion from county evidence alone.
