Who this market fits

Best for
  • +All-cash buyers: removing debt service flips the cap rate to actual yield
Skip if
  • −You need positive cash flow on day one at typical leverage
  • −You can't tolerate negative leverage (cap rate below mortgage rate today)
  • −You expect appreciation to carry the deal, but prices have declined year over year
  • −You rely on FHA-style financing: prices are stretched relative to local incomes

The Bottom Line

HoldKnox is a neutral market. Consider house hacking or targeting below-market deals.

Knox County in Maine scores 46/100, ranking #624 of 1,000 US counties (top 83%). At 20% down and current rates, a median-priced rental loses about $968/month; the 5.56% gross rent-to-price ratio doesn't survive debt service. The thesis here is appreciation, value-add, house hacking, or all-cash.
