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

Washington County presents a yield-versus-growth decision, not a simple appreciation case. The median home value is $434,278, up 6.15%, while Zillow's measured median asking rent is $1,450 per month, up 7.97%; gross yield is only 4.01% before costs. That spread merits investigation by buyers willing to underwrite rent durability, but yield-focused investors should be cautious: vacancy, repairs, financing, or taxes can weaken a pre-cost return at this entry price.

02Housing economics

Measured asking rent is not HUD's payment standard: it is 8.4% above the $1,338 standard, which does not establish achievable asking rent. Price direction is supported, but not merged, by a separate FHFA repeat-transaction index: its annual change was 5.89%, versus a distinct five-year cumulative change of 53.87%. Neither FHFA measure is a dollar home value. Carrying cost is meaningful: effective property tax is 1.10% and median annual tax is $3,802. Test taxes, insurance, maintenance, vacancy, and financing against gross yield.

03Demand & competition

Demand evidence is mixed. Realtor.com MLS evidence shows 377 active listings and a 39-day median marketing time; its median listing price was flat, while days on market rose 12.14% and price reductions affected some listings. These measures describe visible supply, marketing time, and seller concessions, not closed-sale prices or buyer demand by themselves. QCEW adds a mixed labor signal: annual covered county employment contracted while average weekly wages rose; Manufacturing was the largest disclosed private supersector, not the whole economy. Net migration was negative 74 tax-return households, but the average-income gap favored arrivals by $3,216. Investor participation was 5.24% of 1,565 purchase mortgages, measurable but not evidence of dominant competition.

04Risk & next checks

Risk limits center on inland-flood exposure and missing property-level underwriting. The modeled annual building-value loss ratio is 0.08%; it does not replace a parcel flood map, elevation review, deductible, insurance quote, drainage history, or lender requirements. The record also lacks closed-sale comps, unit-level rent and vacancy data, operating expenses, financing terms, turnover costs, and reassessment details. Those gaps prevent a verified net yield, debt-service coverage test, or property-specific flood conclusion. Obtain those inputs before relying on the county thesis.

Bear case

What can break the county thesis

  1. Asking rent may not translate into collected rent; vacancy, turnover, repairs, and operating costs could erase the gross yield.
  2. Covered employment contraction and negative household migration could weaken demand despite higher average income among incoming movers.
  3. Inland-flood exposure, insurance terms, or parcel-level tax reassessment could materially change carrying costs.
Underwriting questions

Before pricing a property

Is the published rent market rent or HUD FMR?

It is median asking rent; HUD FMR is a separate payment standard and is not an asking-rent estimate.

What does QCEW say about the local labor base?

It reports annual covered jobs located in Washington County; employment contracted, average weekly wages rose, and Manufacturing is the largest disclosed private supersector.

Does the record show dominant investor competition?

No. Investor mortgages are a limited share of total purchase mortgages, and the MLS evidence shows visible listings and marketing time; those measures do not prove buyer demand.
