The Bottom Line

HoldJohnson scores well overall, but a typical leveraged buy-and-hold loses $718/mo at current rates. Consider house hacking, value-add, or all-cash; otherwise a worse score with positive cash flow may be the better deal.

Johnson County in Iowa scores 62/100, ranking #0 of 0 US counties (top 50%). At 20% down and current rates, a median-priced rental loses about $718/month; the 5.34% gross rent-to-price ratio doesn't survive debt service. The thesis here is appreciation, value-add, house hacking, or all-cash.
