Two Neighborhoods, One ZIP Code

ZIP code 63125 covers Lemay and part of Mehlville. The price difference inside the ZIP is significant. In 2026, the 63 Mehlville R-IX sales had a $265,000 median; the 27 Hancock Place sales had a $156,500 median. The houses differed too: a median of 1,500 sq ft built in 1960 on the Mehlville R-IX side, versus 1,050 sq ft built in 1940 in Hancock Place.

Lemay sits along the Mississippi River side of the county with Jefferson Barracks Park as the signature anchor. Its housing stock is the oldest in the ZIP.

The mailing city won’t sort it out for you: 65 of the 93 sales listed “St Louis,” 12 “Unincorporated,” 12 “Mehlville” and only 2 “LeMay.”

Three School Districts in One ZIP

This is a housing comparison, not a school comparison. The houses differ by district, so compare the same type of house before deciding what a district line is worth to you.

⚠ School district boundaries do not follow ZIP codes. The district shown for each sale is the one listed in MLS. Verify assigned schools by exact property address with the district before making any decision.

Mostly 1950s–60s Ranches

The housing stock in 63125 is mature. The median 2026 sale was built in 1957 and had about 1,440 square feet. By decade: 19 sales were built before 1940, 9 in the 1940s, 28 in the 1950s, 27 in the 1960s and only 10 in 1970 or later.

Ranches dominate: 56 of the 93 sales (60.2%) listed a ranch style, including ranch combinations, and 18 (19.4%) a bungalow. Split-level, split-foyer and raised-ranch homes were uncommon: 4 sales (4.3%).

83 of the 93 sales (89.2%) were built before 1970, so most houses here are 55 years old or older. HVAC, electrical panels, plumbing and roofing will need attention sooner rather than later.

The 63125 Inspection Checklist

A $190K ranch in Lemay will have $10K-$20K in deferred maintenance. That's the market. Here's what buyers actually find during inspections in this ZIP code:

Common in 1950-1980 construction. Known fire hazard. Insurance companies flag them. Replacement cost: $2K-$4K. Some lenders won't close until replaced.

Standard in pre-1970 construction. They rust from the inside out. Replacement cost: $8K-$15K. Finished basements make access harder and replacement more expensive.

If the home still has galvanized water supply pipes, they're corroded. Low water pressure is the symptom. Replacement cost: $5K-$10K.

Some homes in 63125 sit on slab foundations instead of basements. That means no drain line access without breaking concrete. If you have cast iron drains and a slab foundation, replacement gets expensive fast.

If the furnace or A/C is 15+ years old, budget for replacement. Cost: $6K-$10K for both. Sellers rarely replace HVAC before listing.

FHA and VA loans require roofs to have at least 3 years of remaining life. If the roof is shot, the lender won't close until it's replaced. Know the roof condition before you make an offer.

Who This ZIP Code Actually Fits

First-time buyers with budgets around $180,000–$290,000—the middle half of 2026 sales in 63125—who prioritize payment and understand they’re buying older housing stock.

VA buyers who need the lowest price points in South County and can handle FHA/VA condition requirements.

FHA buyers comfortable negotiating repairs or taking on post-closing projects.

Buyers who value Jefferson Barracks Park access and are comparing 63125 against 63123 (Affton) on monthly payment.

Buyers who want turnkey, zero-maintenance homes. Buyers whose search requires the Lindbergh School District: none of the 2026 sales in 63125 were in Lindbergh. Buyers who assume “South County” means Oakville or Crestwood pricing.
