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

AvoidKing may be challenging for traditional rentals. High prices or low rents make cash flow difficult.

King County in Washington scores 28/100, ranking #753 of 1,000 US counties (top 99%). At 20% down and current rates, a median-priced rental loses about $3110/month; the 3.11% gross rent-to-price ratio doesn't survive debt service. The thesis here is appreciation, value-add, house hacking, or all-cash.
