13 Years Of Real Estate Experience At Your Fingertips
Ranked by real monthly ownership cost -- not just list price. Built from 7,006 MARIS sales across 79 zip codes. Where your budget goes furthest in St. Louis right now.
Affordability is not just list price. It is the monthly cost you actually pay after factoring in the mortgage, property taxes at the real local rate, and insurance. A $200,000 home in a high-tax St. Louis municipality can cost more per month than a $220,000 home in a lower-tax zip code.
These rankings use real MARIS MLS transaction data and local levy rates -- not Zestimate estimates or county averages. The median price shown is from actual closed sales in the past 12 months. Tax rates are municipality-specific where data is available.

What is the most affordable area to buy a home in St. Louis?
North County municipalities including Florissant, Hazelwood, and Berkeley offer the lowest median home prices in the St. Louis metro, typically ranging from $150,000 to $220,000 for median-priced homes. For buyers who prioritize South County schools and neighborhoods, Affton and Lemay offer the most accessible entry points in that region. True affordability depends on the specific zip code's property tax rate, which varies significantly across St. Louis County's 88 municipalities.
How do property taxes affect affordability in St. Louis?
Significantly. St. Louis County property tax rates vary from roughly 1.1% to 2.5% of assessed value depending on municipality and school district. On a $200,000 home, that range represents a monthly difference of $150 to $200. A home in a low-tax municipality can cost meaningfully less per month than a home at the same list price in a high-tax area. Always compare PITI -- not just purchase price -- when evaluating affordability across different St. Louis areas.
Are affordable St. Louis neighborhoods good investments?
Depends on the specific area and your definition of investment. North County affordable areas have shown more modest appreciation than South County and West County over the past decade. However, entry-level homes in stable owner-occupied neighborhoods in any part of St. Louis have generally appreciated with inflation or better. The investment risk in affordable areas is more about market liquidity -- how quickly and at what price you can sell in 5 to 10 years -- than about absolute price decline.
