06  ·  Context

What a gap in sales means

Recent closed sales are the main reference point buyers, lenders and appraisers use to value a unit. When a building goes an extended stretch without one, there are fewer current data points to support a price, and this generally coincides with lower buyer demand and lower sale prices.

At Ka Hale Moi, the record since the last accepted contract shows:

  • Units on the market7
  • Listings cancelled or expired6
  • Units with a lower asking price than originally listed3
  • Units that went under contract0
