Overview
Homes, roads and parks in Mehlville.
The housing mix is mostly single-family: brick ranches, split-levels and two-story homes on curving subdivision streets, plus a solid share of condominiums, villas and apartment communities near the main corridors. That range gives Mehlville one of the wider price spreads in South County, which makes pricing against the right comps especially important.
Lemay Ferry Road (Route 267) is the main north-south corridor, with Lindbergh Boulevard, Telegraph Road and Tesson Ferry Road close by. I-55 runs through the area and I-255 and I-270 are minutes away, connecting to downtown St. Louis and both sides of the river.
For outdoor space, Suson Park on Wells Road has an animal farm, stocked fishing lakes and playgrounds. Bee Tree Park and Cliff Cave Park along the Mississippi River are a short drive south in Oakville, and Jefferson Barracks Park is to the east in Lemay.

Buying in Mehlville
With condos, villas and single-family homes side by side, the first step is matching the property type to your loan. Condo and villa purchases need HOA budget and insurance documents early, and some loan programs review the association. Get a full pre-approval, then compare price per square foot within the same property type.
