@Nick Foundas Often, though not always, the Every Door Direct Mail Route on the USPS website will tell you how many homes are on the route.

Some counties web sites are more user friendly than others you may have to look at a tax parcel map and search by the parcel in the search function.  

Some take commercial breaks and pitch stuff like hard money lenders, business credit, virtual assistants, landlord services, deal partnering, websites, marketing services, home security devices, etc.

Most counties have that information online go to the counties website and search around there is usually a link to a database that houses the property tax information and you can pull up property taxes by address which will give you the current tax bill.

You may not need a lot of money to start but you will be competing with some who have large budgets, send out thousands of mailers monthly, maintain multiple websites, hire answering services, and attend many meetings to keep themselves in front of buyers. 

Also a lot of thrifty multifamily owners know how to hide themselves so your tax assessor's website won't always do the trick.

I just visited your website and seen that it ansewed my questions. 

This is a great website to learn from set up your keywords that you want to be notified with, read lots of post and subjects and I love the podcast.
