Where you will find yourself successful is providing support to your PMs and making them as efficient as possible so they can (comfortably) handle as many properties as possible.I don't know what market rate in your area is but your per door rate seems awfully low.

Buy at the right time to catch a wave of rent growth and force the value up through repairs and efficiencies.

What is the most efficient way to obtain list of absentee owners, tired landlords, distressed owners, or vacant properties?

The learning curve was frustrating the first year but over time I've learned to do it much more efficiently.

I was hoping to get some recommendation for where can I obtain a free or cost efficient business domain and or email address, business phone/ efax number.

I know there is a more efficient way to do this and that is why I am seeking advice.
