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

Monona County is a price-momentum-versus-underwriting-evidence case: investigators able to obtain property-level rent, flood and insurance files may proceed with diligence, while cash-flow-focused buyers should remain cautious. Zillow’s county median home value is $166,631 and rose 2.09%, whereas FHFA’s repeat-transaction HPI increased 10.37% annually. These are separate methods and observation windows: Zillow measures a value estimate, while FHFA is an index rather than a dollar home value. They should not be averaged into a single appreciation rate.

02Housing economics

No county market asking-rent measure is published, so gross yield cannot be computed. HUD’s $919 two-bedroom Fair Market Rent is a payment standard, not evidence of asking rent, and cannot substitute in the calculation. The effective property-tax rate is 1.03%; it creates a carrying-cost line item to verify against the specific assessment, rather than a conclusion about a given home’s tax bill. Rent, vacancy, insurance and operating-expense evidence are absent, preventing an all-in cash-flow conclusion.

03Demand & competition

Realtor.com’s MLS listing market shows a 45.87% year-over-year increase in median asking price, only 26 active listings, down 25.71%, and a 9.11% price-reduced share. These are visible supply and seller-concession signals, not closed-sale prices or proof of buyer demand. Tax-return migration was negative by 17 households, although movers in had average AGI $6,018 above movers out. Investors represented 14.14% of 99 purchase mortgages; that documents non-owner participation in this transaction count, not rental demand or resale liquidity.

04Risk & next checks

Inland flood is the dominant hazard, and modeled annual building-value loss is 0.16%; this county-level model is not a parcel loss estimate. QCEW annual covered employment at county workplaces grew 1.11%, with Education and health services the largest disclosed private supersector at 34.21% of private covered jobs. This is neither resident employment nor unemployment. Underwriting still needs parcel flood maps, insurance quotes and claims history, closed-sale comparables, and unit-level rent, lease-up and expense evidence; without them, hazard-adjusted acquisition cost, income durability and exit pricing cannot be established.

Listing price is an asking price, not a closed sale. Quality-flagged county rows are withheld instead of displayed.

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. Unpublished market rents, vacancy and operating costs may produce unattractive property-level cash flow.
  2. Flood insurance, elevation and claims evidence may reveal costs or exposure not captured by the county model.
  3. MLS asking-price and purchase-mortgage evidence may not translate into closed-sale pricing or buyer depth.
Underwriting questions

Before pricing a property

Can gross yield be calculated from the record?

No. County market asking rent is not published, and HUD Fair Market Rent cannot be used as market rent.

What does the FHFA measure represent?

It is a repeat-transaction home-price index, not a dollar home value.

Which hazard is identified as dominant?

Inland flood.
