The cities inside Lake County

The highest-risk locations in Lake County are Madison and Sinai, each scoring 1.6/10. Madison is by far the county's largest city at 6,094 residents, making it the dominant rental market in the county. Its score reflects the modest concentration of economic and demographic risk factors that come with any county seat, though a 1.6 is still firmly low by any statewide or national measure. Sinai, with a population of 215, reaches the same score at a much smaller scale.

On the lower end, Brant Lake South scores 1/10, the lowest in the county, and Brant Lake comes in at 1.1/10. Wentworth sits at 1.2/10. Chester, Lake Madison, and Ramona fall in the 1.4 to 1.5 range. The spread from 1 to 1.6 is narrow in absolute terms, but it is meaningful: risk is hyper-local even in a uniformly low-risk county, and landlords operating in Madison should not assume their conditions mirror those in Brant Lake South or Wentworth.
