Siskiyou County presents a rental-income case whose support from market rent must be weighed against a softer home-value reading, weakening workplace employment and flood exposure. It warrants investigation by operators able to verify property-level costs and insurance; buyers dependent on a near-term resale or broad job expansion should be cautious. Zillow’s 2026-06 median home value was $286,988 and lower year over year. FHFA’s 2025 repeat-transaction HPI increased, but it is an index, not a home value; differing labels and methods cannot be merged into one appreciation rate.
Median asking market rent was $1,578 per month, and the supplied gross yield was 6.6% before costs. HUD’s $1,249 two-bedroom FMR is a payment standard, not an asking-rent estimate and was not used to derive yield. The effective property-tax rate was 0.64%, so the reported yield is not net income after tax, insurance, repairs, vacancy, management or financing. Rent is published, but those expense inputs are not; net cash flow cannot be calculated.
QCEW’s 2025 annual covered employment at county workplaces fell 2.36%; it is neither resident employment nor unemployment. Education and health services is the largest disclosed private supersector. More tax-return households moved out than in, although inward movers’ average AGI exceeded outward movers’ by $10,943. Investor purchase mortgages accounted for 6.53% of 291 purchases. In Realtor.com’s 2026-06 MLS evidence, median marketing time was 66 days and 15.44% of listings had reductions. These are asking-market supply and concession measures, not sales prices or standalone proof of buyer demand.
Modeled climate loss equals 0.40% of building value per year, and inland flood is the dominant hazard; this is a modeled ratio, not an insurance quote or a dollar loss. The county-level record does not publish flood-zone or elevation exposure, premiums or deductibles, property condition and repair scopes, vacancy, operating costs, debt terms, or closed-sale comparables. Those absences prevent defensible property-level net-cash-flow, insurability and exit-value underwriting; county aggregates also cannot establish a specific neighborhood’s tenant depth or resale liquidity.
