Gross rent includes contract rent plus estimated tenant-paid utilities. It includes existing leases collected during the survey window and is not the rent for a specified bedroom count. Median selected monthly owner costs include mortgage payments where applicable, real estate taxes, insurance, utilities and relevant fees. Mortgage-free housing still has recurring costs.
The ratio of median home value to median household income is 3.2. Dividing these two medians does not pair the income of a buyer with the price of that buyer’s home, and cannot determine an affordable mortgage payment. The city and state tables use the same survey period, currency basis and source definitions. Differences in point estimates are descriptive; they are not tests of statistical significance.

This table’s percentages use all cash-rent units, including those with a ratio not computed. There are 1,638 units with a computed rent-to-income ratio. The “30% to less than 50%” and “50% or more” rows identify rent burdens in the source data; their displayed shares are not directly comparable with a publication that excludes uncomputed ratios from its denominator. Counting a high burden does not tell us why a household chose its home or predict a new renter’s circumstances.

Household incomes behind the median
At the median gross rent of $1,588 a month, a household would need about $63,500 a year to keep rent at 30% of income, a common affordability benchmark. That income falls in the $50,000–$74,999 bracket; 16.9% of all Lake St. Louis households, owners included, report incomes in lower brackets. The brackets cover every household, so they show how widely incomes spread around the $125,693 median.

Check a specific address before moving
City averages help compare places. A particular home’s school assignment, transit service and flood-map coverage need checks at the address.
- FEMA Flood Map Service Center — search the address, read the effective map and its date, and check any map changes. An unmapped location does not establish an absence of flood risk.
- NCES public school district directory — find district contact information, then use the district’s official address locator or enrollment office to confirm school assignment. A city name or district boundary alone does not assign a school.
- FCC National Broadband Map — check reported service at the exact location, then confirm availability and terms with the provider.
- Check the official transit operator’s route map and timetable for the address and your actual travel hours; the citywide commuting shares above do not measure service on a particular street.
What these figures do not measure
This page describes housing costs reported in the 2020–2024 survey, not current listings or a full cost-of-living index. Food, energy, transport, childcare and other prices are not measured for individual cities, and a metropolitan price index such as BEA regional price parities would describe the surrounding region rather than Lake St. Louis itself. For a move, get current lease or purchase quotes for the unit and address you are considering.
