Gentemann iii is a Low Income Housing Tax Credit (LIHTC) apartment community in O Fallon, Missouri. LIHTC properties — also called Section 42 housing or tax credit apartments — are income-restricted rentals developed with federal tax credits administered by state Housing Finance Agencies (HFAs). Qualifying residents pay rent based on a percentage of the Area Median Income (AMI) for O Fallon. Based on 2024 data, the local AMI for the 63366 zip code is $83,794 for a single person and $119,707 for a 4-person household. These figures make O Fallon tax credit apartments among the most affordable rentals available without a Section 8 voucher.
To qualify, your total household income must fall at or below the income limit set for this property. Unlike public housing, LIHTC income-restricted apartments are privately managed and require you to apply directly to the property. Rent is fixed at a discounted rate tied to AMI — not to your specific income — so your monthly payment stays predictable.
By law, LIHTC properties must remain rent-restricted for a minimum of 30 years. Gentemann iii was placed in service around 2010, keeping rents income-restricted at least through ~2010.
You must be of qualifying age. Your income must fall within HUD's Area Median Income (AMI) limits for O Fallon. Based on the 63366 zip code AMI (2024), this property's 50% income limit is approximately $41,897/yr for 1 person / $59,854/yr for a 4-person household.
