Prepper Assessment

Living in this area offers a blend of rural charm and natural beauty, with 1,557 square miles and a low population density of 5.8 people per square mile. The climate features an annual mean temperature of 46.1°F and receives about 19.2 inches of rain per year, supporting a growing season suitable for a range of crops in USDA zone 7a. However, the dry sub-humid classification may limit water availability for extensive agricultural pursuits, making efficient water management essential for self-sufficiency.

Custer County faces notable natural hazards, including a high wildfire risk, ranked 94 by FEMA, which could pose a threat to homesteaders. Additionally, winter weather (ranked 60) can create challenges for year-round living and transportation. The median home price is $294,700, which may be a barrier for new residents, particularly those looking to establish a homestead. While the area has a low violence percentile (97/100), the rural setting may still present challenges in terms of access to emergency services.

This county is well-suited for individuals or families seeking a tranquil, rural lifestyle and who are comfortable with limited amenities. Those with skills in self-sufficient living, such as farming or animal husbandry, may thrive here. However, individuals reliant on urban conveniences or those unprepared for harsh winter conditions may find the area less accommodating. The hidden gem for homesteaders is the low property tax rate of 0.83%, which can help offset the initial investment in land.
