Colleton County is a lower-cost market — the local AMI of $66,200 falls well below the national median of $96,300 and the South Carolina statewide average of $90,500. Income qualification thresholds for federal housing programs are correspondingly lower, meaning that a household relocating from a higher-AMI market might not qualify for the same programs here. For developers, lower AMI levels typically mean tighter operating margins on LIHTC projects.
Rent Affordability in Colleton County
Using the standard 30% rule — a household should spend no more than 30% of gross income on housing — here's the maximum affordable monthly rent at each AMI tier for a 4-person household.
30% AMI
$804/mo
Based on $32,150 annual income
50% AMI
$850/mo
Based on $34,000 annual income
80% AMI
$1,360/mo
Based on $54,400 annual income
The 30% Rule:HUD defines a household as "cost-burdened" when it spends more than 30% of gross income on housing costs (rent plus utilities). Households exceeding 50% are considered "severely cost-burdened." In Colleton County, a family of four earning exactly at 50% AMI ($34,000) should aim to keep total housing costs below $850 per month to avoid cost burden.

What These Numbers Mean For You
In Colleton County, the 2025 Area Median Income of $66,200 falls below the national median of $96,300. This means federal housing program income limits are set lower here — a household must earn less to qualify for the same programs that serve higher-income families in costlier markets.
For renters, the lower AMI can be a double-edged sword. While qualification thresholds are more accessible (50% AMI is just $34,000 for a 4-person household), the affordable rent ceiling of $850/month at that level may more closely align with actual market rents in Colleton County— potentially reducing the gap between "affordable" and "available."
For developers, the lower AMI tightens the economics of LIHTC projects. The 60% AMI cap for a 4-person household in Colleton County is $39,700, which constrains maximum allowable rents and may require additional subsidies or creative financing to achieve feasibility. For city planners in South Carolina, the gap between Colleton County's AMI and the statewide average of $90,500 highlights regional economic disparities worth addressing in housing policy.
