Looking to compile a multiple family mailing list

[George Broderick]

Hi, the 3 counties I invest in dont have a easy way to get a list of multiple family mailing adresses for. I checked listsource and they were not able to do it for me.

How do you guys go about compiling a mailing list of owners of 2-4 unit buildings in specific counties, I am happy to pay if someone can recommend a service provider.
