Hi Griff,
For a welcome service I would start with the sales end. Am I going to sell advertisers blocks of 50 or 100 or more New homeowners? Then go to:
https://www.melissadata.com/lists/ez...omeowners.aspx
Put in the zip codes and you will get the monthly counts on new homeowners for each zip code.
If a zip code contains only 10 or 12 new move in each month then I have to combine two or more zip codes. If a zip code contains 2,000 new move ins each month then I have to break that zip code down into streets or neighborhoods. Then I sell the businesses in that area so the new homeowners are always within easy reach of a business.
Best of success,
Skip Rosell
