They also sell the list of complex - about $100-$120 per complex. So pick the complex with more apartments. Simple. Great service that you can use in your real estate business.
This is one of the invaluable tools that you can use - if you want first time home buyers as your client. Their motto is simple - the address does not change, people do!
