I sorted the CSV by column E so all the blank addresses would be grouped together but I don't see any kind of pattern in the remaining columns that would cause these families to be blank:
- Some have family phones, some don't.
- Some have family emails, some don't.
- Some have kids, some don't.
- Some are active, some aren't (although MLS doesn't know this)
- Some have local area code phone numbers, some don't
- All are married, some have a spouse phone and/or email, some don't
