Mercer County presents a yield-versus-durability screen: investors should investigate whether market-rent income survives property costs, while those needing stable demand should be cautious. In Zillow’s 2026-06 county observation, median home value was $193,661, median asking rent was $861 monthly, and supplied gross yield was 5.34% before costs. Rent increased 5.64%, ahead of Zillow value growth of 1.12%. FHFA’s separately labeled 2025 annual repeat-transaction HPI rose 1.80%; it supports the direction but is neither a home value nor the same vintage or method.
The $861 figure is measured market asking rent; HUD’s $996 two-bedroom Fair Market Rent is a payment standard, not a market-rent estimate. Market rent equals 86.4% of that HUD standard, but no yield should be inferred from HUD. The 1.18% effective property-tax rate and modeled expected annual building-value climate loss of 0.11%, tied to inland flood, narrow the pre-cost yield. Parcel assessments, insurance, maintenance, vacancy, management, and financing costs are not published, preventing a net-cash-flow conclusion.
Demand and buyer competition are mixed. Realtor.com’s MLS listing-market evidence reports 235 active listings and a 15.32% price-reduced share, measures of visible supply and seller concessions rather than closed-sale pricing or proof of buyer demand. Tax-return household flows were net negative by 218, although incoming movers had average income $4,605 above outgoing movers. Investors accounted for 51 of 766 purchase mortgages. Annual QCEW shows covered jobs at county workplaces declined while the covered-worker average weekly wage increased; this is not resident employment or a forecast. Education and health services is the largest disclosed private supersector, not the entire economy.
Risk limits are property-specific. The record does not publish closed-sale comparables, lease occupancy and turnover, parcel tax assessments, debt terms, flood-zone status, insurance quotes, or building condition. Their absence prevents an asset-level conclusion on acquisition price, net cash flow, debt coverage, and flood expense. Next checks should include lease and rent comparables, the current tax bill, flood disclosure and insurance terms, and closed transaction comparables; county evidence cannot substitute for them.
