Warren County presents a yield-versus-liquidity tension: Zillow’s median home value is $338,800 while median asking rent is $1,225 per month and supplied gross yield is 4.34% before costs. Value rose 1.94% year over year while asking rent rose 8.71%, a spread worth testing through lease comparables and operating costs; resale-dependent underwriting deserves caution. HUD FMR is a payment standard, not a market-rent estimate, and is not used to derive yield.
Carrying costs may narrow the gross spread: effective property tax is 0.70%, but parcel assessment and insurance costs are not published. Zillow’s value movement and FHFA’s repeat-transaction HPI use different methods and supplied periods. FHFA shows a 5.58% annual index change and a 61.47% cumulative five-year index change, not a dollar value; these rates should not be averaged. Realtor.com MLS evidence shows listing prices down 1.62%, 63 median days on market, and 14.01% of listings reduced. These are asking-price, marketing-time, and concession measures—not closed sales or proof of buyer demand.
Demand evidence is mixed rather than conclusive. Net migration was 236 tax-return households, while incoming movers’ average income exceeded outgoing movers’ by $187. That gap does not establish local rental absorption. Investor participation was 39 purchases among 531 total purchases, so buyer mix and investor depth need local transaction review. QCEW describes annual covered jobs at county workplaces, not resident employment or unemployment; Manufacturing is the largest disclosed private supersector, not the entire economy. Its wage is a covered-worker average, not household income.
Risk limits are material. Inland flood is the dominant hazard, and modeled expected annual climate loss equals 0.15% of building value; it is a model, not an insurance quote or parcel outcome. The thesis can fail if property-specific flood exposure or insurance erodes gross yield, if the softer MLS posture persists into closed-sale pricing, or if migration does not translate into rental absorption. Obtain parcel flood history and insurance, lease comps and vacancy records, and closed-sale financing data; their absence prevents net-yield, exit-price, and tenant-demand conclusions.
