Market rent and voucher rent by ZIP code in Saint Louis
Each row is one tracked ZIP code. The last column compares a two-bedroom HUD reference with Zillow's all-size rent index. A positive number is not a matched-unit premium or proof that a voucher tenancy can support more rent. Check bedroom-matched comparable rentals and the authority's adopted schedule separately.

What this means if you own a rental in Saint Louis
- Check the local comparison set. The highest tracked ZIP index is 2.0 times the lowest. Check unit type and bedroom-matched comps before using that spread to price a property.
- Verify the voucher calculation independently. HUD references and all-size ZORI describe different things. Obtain the housing authority's payment standard and utility allowance, then check rent reasonableness for the actual unit. The table cannot determine a voucher premium, turnover rate or collection outcome.
- Test the deal without future rent increases. County rents are up 3.6% from a year ago. That observation does not establish the increase available on a particular lease. Compare a flat-rent case before choosing a growth assumption.
To test a specific property, run it through the Section 8 rent analyzer, which compares voucher rent and market rent for your ZIP and unit size. The Missouri HUD-to-rent-index comparison provides broader research context; its ratios do not establish property-level premiums.
Where these numbers come from
- Market rent: the Zillow Observed Rent Index by ZIP code, refreshed monthly. It blends all unit sizes, so compare it with voucher figures as a guide and not as a like for like two bedroom rent.
- Fair Market Rents and Small Area FMRs: HUD User, published each fiscal year.
- County rent history: Zillow rent data, last reading of each calendar year.
Confirm the current payment standard, utility allowance and applicable rules with the administering housing authority before underwriting a voucher tenancy. Use matched comparable rentals for the market-rent assumption.
