Castle mountain is a Low Income Housing Tax Credit (LIHTC) apartment community in White Sulphur Spring, Montana. 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 White Sulphur Spring. These properties are among the most affordable apartments available without a Section 8 voucher.
To qualify, your total household income must fall at or below the income limit set for this property — currently 60% AMGI of AMI. 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. Castle mountain was placed in service around 2010, keeping rents income-restricted at least through ~2056. This property has an extended 46-year affordability commitment — providing long-term housing stability well beyond the minimum.
You must be of qualifying age. Your income must fall within HUD's Area Median Income (AMI) limits for White Sulphur Spring.

Yes. HFA records classify this as a new construction LIHTC property, meaning units were purpose-built as affordable housing rather than converted from existing stock. New construction properties often feature modern layouts and energy-efficient systems. It's worth asking management about the age of appliances and any known maintenance issues before applying.
According to HFA records, this LIHTC property is specifically designated to serve elderly residents. This means it may have specialized services, accessible units, or preference policies that prioritize these groups. Contact management to understand their current preference and waitlist selection process — being in a designated group does not guarantee priority without a formal application.
