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

Calhoun County presents a price-versus-income-underwriting tension: Zillow reports a $203,873 median home value, up 2.72% year over year, yet no county market rent is published. Income-focused or leveraged buyers should be cautious, because gross yield cannot be computed without measured asking rent; buyers who can obtain property-level rent and expense evidence should investigate whether the price movement is supportable. This is a county reading, not evidence that Calhoun behaves like the St. Louis metro.

02Housing economics

HUD’s monthly $1,218 Fair Market Rent is a payment standard, not an estimate of Calhoun asking rent, so it cannot replace the missing rent or create a yield. Carrying-cost review is nevertheless material: the effective property-tax rate is 1.39%, with median annual tax of $2,644. Those county figures frame cost burden but do not establish a subject parcel’s assessment, tax bill, insurance, maintenance, vacancy, or debt service; without those inputs, price appreciation does not resolve cash flow.

03Demand & competition

Workplace and mover evidence is mixed rather than a demand verdict. QCEW reports 744 annual average covered jobs and a $721 average weekly wage; Education and health services, the largest disclosed private supersector, accounts for 111 covered jobs. These are jobs at county workplaces and a covered-worker wage average, not resident employment or unemployment. Tax-return migration shows 48 households moving in and 51 moving out, while incoming movers’ average AGI exceeded outbound movers’ by $25,429. Non-occupant borrowers made 3 of 39 purchase mortgages, a 7.69% investor share; that measures mortgage purchases, not all buyer competition.

04Risk & next checks

Inland flood is the dominant listed hazard, and modeled climate loss is 0.39% of building value per year; it is an expected-loss ratio, not a forecast or a property-specific insurance quote. FHFA annual HPI observations are not published, so Zillow’s direction cannot be checked with a repeat-transaction index or merged into another growth rate. Published Realtor.com MLS listing price, active listings, marketing time, and price-reduction data are also absent, preventing a read on visible supply and seller concessions. Next checks are property-level rent comps, flood history and insurance, taxes, and current listings.

Bear case

What can break the county thesis

  1. Unpublished market rent, vacancy, and operating-cost evidence could make the apparent price level unaffordable on a cash-flow basis.
  2. County modeled flood loss may not reflect parcel-level exposure, insurance availability, or actual repair costs.
  3. Missing FHFA and Realtor.com listing measures leave Zillow’s value movement untested against transaction-index and visible-supply evidence.
Underwriting questions

Before pricing a property

Can gross yield be calculated from the record?

No. County market rent is not published, and HUD Fair Market Rent is not a substitute for asking rent.

What does the QCEW employment figure represent?

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

What is the listed dominant hazard?

Inland flood; the record provides a modeled climate-loss ratio rather than a site-specific loss estimate.
