Do two methods point the same way?

Zillow estimates a current home value. FHFA tracks repeat mortgage transactions. Their growth rates should be read side by side, not averaged.

County brief

What the local evidence says

01Decision frame

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.

02Housing economics

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.

03Demand & competition

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.

04Risk & next checks

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.

No rent index is published for this county.Zillow’s county rent series does not cover every county, and estimating one from a neighbouring county would be a guess wearing a number’s clothes. Everything above is measured here; no wider market is mapped for it either.
Bear case

What can break the county thesis

  1. Actual market rent, vacancy and operating costs may not support the acquisition price or carrying costs.
  2. Thin purchase and population counts may make county-level price and investor measures unstable or unrepresentative of a specific property.
  3. Inland-flood exposure, insurance terms and parcel tax assessment may differ materially from county-level modeled and median figures.
Underwriting questions

Before pricing a property

Can gross yield be calculated from this record?

No. Market rent is not published, and HUD Fair Market Rent cannot be substituted for asking rent.

Does the record show investor competition?

It records no investor purchases, but the total purchase count is too small to establish the level of competition.

Is Zillow’s price direction independently confirmed by FHFA?

No. No FHFA annual repeat-transaction HPI observation is supplied.
