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

Marion County’s decision tension is whether rising price measures can support an acquisition when rent coverage is unmeasured. At Zillow’s 2026-06 observation, median home value was $199,480, up 4.54% year over year, while FHFA’s 2025 repeat-transaction HPI rose 9.14% annually. Both point upward, but they use distinct measures and vintages; HPI is not a home value and should not be blended with Zillow’s change. Investors should investigate rent coverage; cautious buyers should not treat appreciation evidence as cash-flow evidence.

02Housing economics

No county market asking rent is published, so gross yield cannot be computed. HUD’s two-bedroom FMR of $952 per month is a payment standard, not an asking-rent estimate, and cannot substitute for rent. The effective property-tax rate is 0.82%; it adds a known carrying-cost line but does not establish tax on a specific acquisition. Underwriters need rent comps, operating expenses, insurance, and assessed-value treatment to test coverage against the observed price.

03Demand & competition

Realtor.com’s MLS evidence shows 49 active listings, a 65-day median marketing time, and 20.35% of listings with price reductions. These are visible asking-market supply, marketing-time and seller-concession measures—not closed prices or standalone proof of buyer demand. QCEW’s annual average reports covered employment at county workplaces up 0.59%, with education and health services the largest disclosed private supersector; this is neither resident employment nor an employment forecast. Net tax-return migration was negative 15, and the mover-income gap was negative $4,140. Investor participation was 11.64% of 292 purchase mortgages; together, these measures warrant scrutiny of tenant and owner-occupier depth rather than a conclusion about demand.

04Risk & next checks

Inland flood is the dominant hazard, and modeled expected annual building-value loss is 0.18%. That model is a risk screen, not a parcel-specific loss or insurance quote; it should be tested against flood zone, elevation, prior claims, deductible, replacement cost, and available coverage. County evidence cannot determine neighborhood rent resilience, property condition, financing terms, or actual buyer mix. Next checks are address-level flood and insurance diligence, rent comps and lease turnover, tax bills and assessment appeal status, and closed-sale and contract data.

Bear case

What can break the county thesis

  1. Comparable rents may not support acquisition costs after taxes, insurance, and operating expenses.
  2. Parcel flood exposure or insurance terms may be worse than the county-level model indicates.
  3. County labor, migration, and MLS measures may not describe the tenant pool or buyer mix for a specific property.
Underwriting questions

Before pricing a property

Can gross yield be calculated from this record?

No. County market rent is not published, and HUD FMR is not a market-rent proxy.

What does the QCEW employment measure represent?

It is annual covered employment at workplaces in the county, not resident employment, unemployment, or a forecast.

Which hazard requires address-level diligence?

Inland flood; the county-level climate-loss model does not replace parcel flood, insurance, and claims review.
