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

Clark County presents a price-momentum-versus-income-and-risk tension: investigators seeking a rental acquisition should test site-level rent and flood costs, while buyers relying on appreciation or quick resale should be cautious. Zillow’s county median home value was $150,341 in 2026-06, up 8.77% year over year. FHFA’s 2025 annual repeat-transaction HPI rose 3.10%. Both point upward, but they are different vintages and methods: FHFA is an index rather than a home value, so neither figure supplies a common growth rate or a valuation conclusion.

02Housing economics

Housing economics remain unproven for rentals. No county market asking rent is published, so gross yield cannot be computed. HUD’s $1,009 two-bedroom FMR is a payment standard, not a market-rent estimate and cannot fill that gap. The effective property-tax rate is 1.56%, a carrying-cost input that must be underwritten beside purchase price, insurance, maintenance and actual lease evidence; no tax bill tied to a target property is supplied.

03Demand & competition

Visible MLS conditions require care rather than a demand claim. Realtor.com recorded 25 active listings and 11.69% of listings with price reductions. These are active-listing asking-market measures, not sale prices or proof of buyer demand. QCEW annual covered employment at county workplaces fell 2.16%; Manufacturing is the largest disclosed private supersector, not the whole economy. Migration was negative by five tax-return households, while average income of departing movers exceeded incoming movers by $1,954. That combination warrants verification of tenant and buyer depth. Investor mortgages numbered three of 69 purchases, limited observed investor competition but too small a base to characterize all buyers.

04Risk & next checks

The principal modeled climate limit is inland flood: expected annual building-value loss is 0.13%, a modeled ratio rather than a property-specific damage estimate. It should be checked against address-level flood exposure, insurance availability and premium quotes before a rent conclusion. Missing closed-sale comparables, market asking rents, lease-up and vacancy data, property condition, insurance costs and debt terms prevent estimates of achievable yield, resale proceeds, cash flow or coverage. County-level evidence cannot establish the target home’s flood risk or tenant demand.

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. Actual market rents and vacancy could be insufficient relative to price, tax, insurance and maintenance costs.
  2. Property-specific flood exposure or insurance pricing could exceed the county-level modeled risk.
  3. Workplace job losses and out-migration could coincide with weaker tenant or resale depth than listing data indicates.
Underwriting questions

Before pricing a property

Can gross yield be calculated from the record?

No. County market asking rent is not published, and HUD FMR cannot be substituted for market rent.

What does the record show about investor mortgage participation?

Three of 69 purchase mortgages were to non-occupants, indicating limited observed investor participation in this measure.

What is the named dominant hazard and modeled loss ratio?

The dominant hazard is inland flood, with modeled expected annual building-value loss of 0.13%.
