Dixon Has More Pre-1940 Homes Than New Builds. Appraising That Requires Local Knowledge of Every Era.

Dixon is a Rock River city with a housing stock that spans more than a century of construction. Thirty-one percent of homes predate 1940, and another 36% were built between 1940 and 1969. That 67% pre-1970 share means deferred maintenance, original wiring and plumbing, and functional obsolescence are standard appraisal considerations rather than exceptions. At the same time, new construction permits in 2024 averaged $296,600, more than double the city median. That gap between the older stock and what a new build costs is one reason the practical appraisal range in Dixon runs roughly $60,000 to $375,000, with tight comp volume at either end.

The Rock River creates the sharpest value divider in the city. North-bank properties closer to the historic downtown and waterfront parks generally command a premium over the south side. The river also creates real FEMA flood zone exposure along the floodplain. Lee County has seen four federal flood disaster declarations, and riverfront and low-lying properties require FEMA Flood Insurance Rate Map verification before the comparable search begins. A flood zone parcel cannot be held equivalent to a dry-land comparable without an adjustment that accounts for the insurance cost and narrowed buyer pool.

With a 46.8% renter-occupied share — well above the Illinois average of around 35% — Dixon carries a meaningful investment property appraisal market. Rental income, cap rate analysis, and gross rent multipliers are regular components of assignments here. The cost of living index sits at 75.5, which is 24.5% below the national average, and that affordability draws investors from the Rockford market and beyond. Appraising those properties requires a clean separation of investment value from owner-occupant comparables.

The Rock River divides Dixon's residential market in meaningful ways. The north side of the river, with its higher elevation and proximity to the historic downtown, Galena Avenue, and the War Memorial Arch, holds the established mid-century neighborhoods where values run roughly $90,000 to $220,000. The downtown and historic district area, where the National Historic District designation applies and Victorian and early 20th-century homes sit close together, trades in a $80,000 to $200,000 range depending heavily on condition and renovation quality.

South Dixon, closer to the industrial employers along the Route 2 corridor and the BorgWarner and Raynor Garage Doors plants, is the lower end of the market, with most homes in the $55,000 to $140,000 range. The Lowell Park area to the north and properties along the riverfront near the Reagan Boyhood Home and Lincoln Monument attract a different buyer profile and carry premiums of $150,000 to $350,000 or more for well-maintained or renovated properties. New construction near the Route 2 corridor and Plaza North area runs $250,000 to $375,000. Each of these sub-markets requires its own comparable pool to appraise accurately.
