How this was calculated
We picked the 3 comparable properties below — same town, within 5 miles, ±30% living area, ±50% lot acreage, that sold in the last 36 months for $50,000 or more in an arms-length transaction. Each sale price was translated to today's dollars using a 7% annual appreciation rate (fit from 259 Bethlehem sales over the last 10 years). The estimate range comes from the 25th–75th percentile of the adjusted price-per-sqft across those comparables, multiplied by this parcel's 2,489 sqft.
Only 3 comparable sales found within 5 miles in the last 36 months.

Sale prices are drawn from the Bethlehem Town Clerk via the VGSI assessor cards and the CT OPM statewide sales dataset. Family / estate / nominal transfers (recorded below $50,000 or flagged non-arms-length by the state) are excluded.
This estimate is informational only — not an appraisal, a comparative market analysis prepared by a licensed agent, or an offer to buy or sell property. Building condition, recent renovations, waterfront / view, and other property-specific factors are not accounted for and can move the actual value substantially in either direction.
