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

Grant County presents a two-sided underwriting case: measured asking-rent potential and positive price signals, but weaker demand and unresolved carrying costs. Zillow's 2026-06 median home value is $229,957, up 6.81%. FHFA's 2025 repeat-transaction HPI is up 3.59%; it is a separate vintage and method, not a home value and not an average with Zillow. The thesis is selective: investors who verify rent collection and flood exposure merit investigation; leveraged buyers relying on appreciation or population growth should be cautious.

02Housing economics

Published median asking rent is $1,208 per month, producing the supplied 6.3% gross yield before operating costs. HUD's $973 two-bedroom FMR is a payment standard, not a market-rent estimate, so it cannot validate asking rent. The 1.36% effective property-tax rate is a recurring carrying cost against gross yield. The modeled annual climate-loss ratio is 0.10% of building value, with inland flood dominant. Parcel-level insurance, deductible, elevation, drainage, condition, vacancy, repairs, management, financing, and lease collections are missing; net yield and cash flow cannot be underwritten.

03Demand & competition

Demand evidence is mixed. Net migration is -83, while average AGI is $50,716 for inbound mover households versus $56,510 outbound, so the recorded flow is not a high-income inflow. QCEW covered employment is workplace employment, not resident employment; it declined year over year while the covered-worker average weekly wage rose. Trade, transportation, and utilities is the largest disclosed private supersector, making local employer and wage depth more relevant than metro assumptions. Investor participation is 11.61% of 353 purchase mortgages, a minority share that does not establish intense investor competition or buyer demand.

04Risk & next checks

Next obtain Realtor MLS listing-market measures, closed-sale comparables, property-specific rent comps and lease terms, insurance quotes, flood-zone and elevation data, and vacancy, repair, financing, and management assumptions. These gaps prevent a net operating income, debt-service coverage, or reliable after-tax return conclusion. They also prevent deciding whether the Zillow value is supported by closed transactions or whether asking rent is collectible. The record supports screening, not a county-wide demand or exit-liquidity conclusion.

What can break the county thesis

  1. Asking rent may not translate into collected lease revenue, and the supplied gross yield excludes operating and financing costs.
  2. Inland-flood exposure may produce insurance, deductible, elevation, drainage, or repair costs not captured by the modeled loss ratio.
  3. Outmigration, lower inbound mover income, and declining covered employment may weaken tenant depth or resale liquidity.
Underwriting questions

Before pricing a property

Is the rent figure market rent or HUD FMR?

It is published median asking rent; HUD FMR is a separate payment standard and should not be treated as market rent.

How should Zillow and FHFA be used together?

Use Zillow as a median home-value observation and FHFA as a repeat-transaction appreciation index; their separate periods and methods should not be averaged.

What does the investor share establish?

It shows the share of purchase mortgages to non-occupants, but it does not by itself prove buyer demand or intense investor competition.
