Direct marketing - Finding information on a current owner

[Chris Mancini]

BP,

For those of you that do their own direct marketing, has anyone found a way to locate a current home owners phone number?  For example, when I find a potential house that seems like an opportunity, I check the tax record and get the owners name and mailing address, but I was looking to see if anyone has found a way to take it a step further and identify a current owners phone number..?

Thanks for the help,

Chris
