WHOLESALERS how do you select or filter neighborhoods to look in?

[Andre Crabb]

For wholesalers...what approach have you found to be more successful?

Whatever your method of contact is...cold calling, door knocking, sending letters...

...how do you choose which neighborhoods to go after? Do you filter them down in any way? Are some usually better for deals than others?

Or if we're buying lists, do we just send to everyone? (spray and pray style?)
