SheHecheyanu: Acquisitions: When To Bless over New Home

If you buy a house, condominium, apartment, or other accommodation, say she'hecheyanu:
  • When you buy it, if it is ready to move in when you buy it (if you will live there by yourself).
  •  When you move in, if it is not ready to move in when you buy it (if you will live there by yourself). 
Note If you are married, say ha'tov v'ha'meitiv instead of she'hecheyanu.
