Petroleum County presents a narrow underwriting tension: a $212,265 Zillow county median home value, down 1.41% in 2026-06, sits alongside improving covered-payroll measures but only five of eight evidence groups. Investors who can verify property-level rent, condition, insurance and resale liquidity should investigate; those needing demonstrated cash flow or reliable transaction depth should be cautious. The population is 447, so county aggregates may be especially thin and should not substitute for parcel-level diligence.
Housing economics are incomplete. Market rent is not published, so gross yield cannot be computed. HUD’s $1,548 two-bedroom Fair Market Rent is a payment standard, not an estimate of asking rent and cannot be used to infer yield. The effective property-tax rate is 0.60%, while median annual property tax is $1,211; neither figure establishes the tax bill for a home at the Zillow value. Modeled annual climate loss is 0.18% of building value, consistent with inland flood as the dominant hazard and requiring property-specific flood and insurance review.
Covered employment at county workplaces averaged 104 jobs in 2025, up 4.00%, across 25 establishments. Average weekly covered-worker pay was $709, up 6.46%. These are workplace measures rather than resident employment, unemployment or a forecast. Natural resources and mining is named as the largest disclosed private supersector, but its supplied employment and share are both zero, preventing a usable sector-concentration assessment. Two purchases were recorded and none were investor purchases, so the reported investor share is 0.00%; this indicates no observed investor participation in a very small purchase count, not an absence of buyer competition. No migration, mover-income, or Realtor.com listing metrics are published for the 2026-06 inventory period.
Key limits remain transaction and income verification. No FHFA annual HPI observation is supplied, so Zillow’s 2026-06 decline has no independent repeat-transaction index check. Missing MLS median listing price, active listings, days on market and price-reduction share prevent an assessment of visible supply, marketing time or seller concessions; those measures would still be listing-market evidence rather than closed sales. Obtain current rent comparables and leases, closed-sale records, flood-zone and insurance quotes, tax assessments, and property condition evidence before drawing conclusions on yield, exit price or carrying costs.
