The Bottom Line

Buy for appreciationAdams scores strongly overall, but a leveraged buy-and-hold loses $181/mo at current rates. Best fit for appreciation-focused buyers, all-cash operators, or value-add deals below median.

Adams County in Illinois scores 77/100, ranking #29 of 1,000 US counties (top 4%). At 20% down and current rates, a median-priced rental loses about $181/month; the 7.87% gross rent-to-price ratio doesn't survive debt service. The thesis here is appreciation, value-add, house hacking, or all-cash.
