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

Stephenson County’s tension is a gross-yield case versus rent, tax and flood uncertainty that can erode it. Investors able to verify lease durability and parcel costs should investigate; those needing evidence of household expansion or low carrying-cost uncertainty should be cautious. In Zillow’s 2026-06 county reading, median home value was $162,128 and median asking rent was $893 monthly; the supplied gross yield is 6.61% before costs.

02Housing economics

The rent is measured market asking rent, not a subsidy benchmark. HUD’s two-bedroom FMR exceeds this rent, but it is a payment standard rather than an estimate of asking rent and cannot be substituted for rent or yield. The 2.40% effective property-tax rate makes carrying-cost diligence central, while gross yield excludes taxes, insurance, maintenance, vacancy and flood-related expense. The rent-price relationship requires unit-level lease and renewal evidence rather than extrapolation.

03Demand & competition

FHFA’s annual 2025 repeat-transaction HPI increased 12.35%. It supports Zillow’s positive price direction, but it is not a home value and cannot be averaged with Zillow’s 2026-06 value trend because the methods and time labels differ. Realtor.com’s MLS evidence carries the same 2026-06 label and shows 94 active listings, with 17.48% reduced; this is visible asking-market supply and seller-concession evidence, not closed prices or standalone proof of demand. QCEW describes annual covered employment at county workplaces, not resident employment; Manufacturing is the largest disclosed private supersector.

04Risk & next checks

Demand signals are mixed: net migration was negative 37 tax-return households, while outgoing movers’ average AGI exceeded incoming movers’ by $8,581. Investor purchase mortgages accounted for 30 of 379 purchases, or 7.92%; this measures financed investor participation, not all buyers. Inland flood is the dominant hazard, with modeled annual climate loss of 0.12% of building value; that is county-level modeled exposure, not a parcel loss estimate. Missing closed-sale comps, unit-level rent and occupancy history, insurance quotes and flood-zone details prevent conclusions on acquisition basis, durable income and all-in operating costs.

Bear case

What can break the county thesis

  1. Asking-rent growth may not translate into executed leases or renewals.
  2. Flood exposure, insurance costs and property taxes may absorb pre-cost yield.
  3. Net outmigration and lower incoming mover income may constrain tenant or buyer depth.
Underwriting questions

Before pricing a property

What does HUD FMR represent in this record?

What does QCEW employment measure?

Annual covered jobs at workplaces in the county, not resident employment or unemployment.

What do Realtor.com listing figures measure?

MLS asking-market prices and visible active supply, not closed-sale prices.
