The central tension in Naugatuck Valley Planning Region is strong historical index appreciation against softer later MLS asking-price evidence. Cash-flow buyers should investigate only with property-level rents and expenses; buyers relying on continued price momentum should be cautious. FHFA’s 2025 repeat-transaction HPI increased 6.41% year over year and 64.87% cumulatively over five years. That index tracks repeat transactions, not a home value, and must not be averaged with the separate Realtor.com observation.
In Realtor.com’s 2026-06 MLS market evidence, median listing price fell 2.31% year over year, and 11.03% of listings had price reductions. These are asking-price and seller-concession signals, not closed-sale evidence; active listings measure only visible supply. Market rent is not published, so gross yield cannot be computed. HUD Fair Market Rent is a payment standard, not market or asking rent. ACS owner-occupied values and occupied-unit gross rents are separate survey contexts, not current asking measures, and cannot be paired into yield. The 1.88% effective property-tax rate is a carrying cost that must be applied at the parcel level.
Buyer competition is visible but qualified: the 130.76% pending-to-active ratio compares pending listings with active listings and is not proof of buyer demand by itself. Investors accounted for 396 of 4,776 purchases, or 8.29%, so non-owner participation is present but not the whole buyer base. Net migration was positive, yet arriving movers’ average AGI was $4,025 lower than departing movers’. The annual QCEW workplace record shows covered employment down 0.25%; it is neither resident employment nor an unemployment measure. Education and health services is the largest disclosed private supersector, not the county’s entire economy.
Inland flood is the dominant hazard, and the modeled annual climate-loss ratio equals 0.17% of building value; it is not a parcel-level loss estimate. The supplied ACS vacancy, tenure, rent-burden, and housing-stock measures are descriptive survey estimates, not forecasts. Parcel-level flood maps, elevation, insurance quotes, property condition and capital needs, current rent rolls, closed-sale comparables, and debt terms are not published in the record. That absence prevents a defensible parcel NOI, debt-service coverage, flood-adjusted carrying-cost, or exit-price conclusion.
