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

Green County’s decision tension is a rising valuation against a pre-cost income return. The Zillow county observation is labeled 2026-06: median home value is $338,699 and median asking rent is $1,567 per month, with a supplied 5.55% gross yield. Income-focused buyers should investigate whether unreported costs leave margin. Zillow’s 5.59% year-over-year value change is directionally consistent with FHFA’s 5.17% repeat-transaction HPI annual change labeled 2025, but the methods and observation periods are different.

02Housing economics

Market rent—not HUD—underpins the yield. HUD’s $1,097 two-bedroom FMR is a payment standard, not an asking-rent estimate; the supplied asking-rent-to-FMR comparison is 142.8%. The effective property-tax rate is 1.6%, a carrying-cost input alongside insurance, repairs, vacancy, management and financing, none of which is published. FHFA’s 59.76% cumulative five-year HPI change is index movement rather than a dollar home value and must not be combined with Zillow’s change.

03Demand & competition

QCEW’s 2025 annual average records 15,755 covered jobs at county workplaces, up 1.36%, with an average weekly wage for covered workers. These are workplace rather than resident labor measures; Manufacturing is the largest disclosed private supersector, not the whole economy. Net tax-return migration is positive, and incoming movers’ average income exceeds outgoing movers’ by $7,076, a composition clue rather than proof of tenant absorption. The record shows investor purchase mortgages at 12.1% of 405 purchases, indicating a buyer segment but not its bidding behavior or local concentration.

04Risk & next checks

Inland flood is the dominant hazard, while modeled expected annual building-value loss is about 0.10%; that model is not observed loss and cannot replace property-level flood-zone, insurance and mitigation review. Realtor.com MLS listing-market figures are not published in this record, preventing assessment of visible supply, marketing time and seller concessions; they also would not be closed-sale evidence. Underwriting still needs lease comparables, vacancy, operating expenses, insurance, financing terms and closed sales. Without them, durable net income, hazard cost and resale support cannot be concluded.

Bear case

What can break the county thesis

  1. Flood insurance, mitigation needs, repairs or vacancy could consume the stated pre-cost yield.
  2. Missing MLS inventory, days-on-market and price-reduction evidence may conceal weaker listing conditions.
  3. County workplace employment and tax-return migration may not translate into demand for the specific property or submarket.
Underwriting questions

Before pricing a property

Is the gross yield based on market rent or HUD FMR?

It is supplied as a pre-cost gross yield based on measured market asking rent; HUD FMR is separately a payment standard.

What does the available employment evidence measure?

It measures annual average QCEW covered jobs located at county workplaces and the covered-worker average weekly wage, not resident employment or unemployment.

Can visible MLS supply and seller concessions be assessed from this record?

No. Realtor.com active listings, marketing time and price-reduction figures are not published in the record.
