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

Martin County’s decision tension is a weakening value signal alongside stronger measured rent: the Zillow county observation for 2026-06 puts median home value down 2.88% year over year while median asking rent rose 4.61%. The annual FHFA repeat-transaction HPI observation for 2025 also fell 1.68%, so it directionally corroborates Zillow rather than serving as a valuation. Income buyers should investigate deal-level costs; buyers relying on appreciation should be cautious.

02Housing economics

At a $449,805 median home value and $2,291 monthly median asking rent, supplied gross yield is 6.11% before costs. This is measured market rent, not HUD’s two-bedroom Fair Market Rent payment standard; FMR cannot substitute for market rent in yield underwriting. The effective property-tax rate is 0.77%. Insurance, financing, vacancy, repairs, and assessed-value treatment are not published, preventing net-cash-flow or affordability conclusions.

03Demand & competition

Realtor.com’s 2026-06 MLS market has active listings down 23.29% year over year yet a 17.69% price-reduced share; these are visible supply and seller-concession evidence, not sales or demand proof. Tax-return movers produced positive net migration, and inbound movers’ average income exceeded outbound movers’ by $53,046. Investor purchase mortgages were 144 of 1,877 purchases, or 7.67%, indicating participation but not establishing the depth of investor competition beyond financed purchases.

04Risk & next checks

Hurricane is the dominant hazard, and modeled annual climate loss equals 0.36% of building value; it changes cost and resilience diligence rather than giving a property-specific loss. The 2025 QCEW annual average counted 77,703 covered jobs, up 1.56%, at county workplaces; it is not resident employment or unemployment. County aggregates cannot identify a property’s flood zone, roof condition, or insurance deductible. Next checks are address-specific hurricane and flood exposure, insurance quotes, tax bill and assessment, rent comps and lease terms, condition, and closed-sales comps. These omissions prevent a net-yield, replacement-cost, or exit-price conclusion.

Bear case

What can break the county thesis

  1. Address-level hurricane exposure, insurance premiums, and deductibles could overwhelm the pre-cost gross-yield figure.
  2. County-level asking rent may not match a specific property’s achievable rent, vacancy, lease duration, or condition.
  3. MLS listing evidence and price reductions may not translate into closed-sale value or exit liquidity.
Underwriting questions

Before pricing a property

Do Zillow and FHFA provide same-period price evidence?

No. Zillow’s county observation is labeled 2026-06, while FHFA’s repeat-transaction HPI is annual 2025 evidence.

Can HUD Fair Market Rent be used to calculate market gross yield?

No. The $1,757 two-bedroom FMR is a payment standard, while the record separately provides measured market asking rent.

What share of purchase mortgages went to investors?

Investor purchase mortgages were 144 of 1,877 purchases, or 7.67%.
