Collinsville Home Values

Collinsville's housing stock splits into two distinct layers. In town, a thin inventory of small-lot homes from the 1920s through 1960s sits on quarter-acre parcels — pier-and-beam cottages and mid-century ranch houses, many updated with modern mechanicals beneath original bones. Beyond city limits, the market shifts to custom homes on multi-acre tracts with equestrian infrastructure: pipe-fenced pastures, hay barns with stalls, riding pads, and working pens. Patterson Premier builds new construction on three-quarter-acre to one-acre sites with cedar beams, knotty alder interiors, and metal roofing. Raw land parcels of ten to twenty-plus acres with ag exemptions and pond features dominate upper price tiers.

Collinsville's recent closings are landing at roughly $265 per square foot — a meaningful step up from the trailing annual average near $205, suggesting the most recent transactions reflect a higher-price segment of the local housing stock. The median sale price among recent closings settled around $570,000, based on MLS data for 2026-05 closings in Collinsville, with sellers receiving close to 98 cents on the dollar. About one in five closed transactions included a seller concession, down from roughly one in three over the prior year, indicating that price negotiation has compressed on deals that are actually closing. Year-over-year price appreciation registers near 19 percent.

Active inventory in Collinsville holds at roughly 83 homes, while the pending count has pulled back to around 14 — a notably lean pipeline relative to the volume of listings on market. Months of supply sits near 12, well above the threshold that signals balanced conditions. New listings continue to arrive at a moderate pace, with about 41 added over the trailing three months. Days on market for recent transactions has compressed sharply, though the mismatch between active and pending inventory suggests selective buyer engagement rather than broad-based absorption.
