GO FOR QUANTITY (the most you can touch in each mailing) and FREQUENCY (touch them monthly).

Another thing worth considering is - if you have only one or two properties, some people might be tempted to "roll the dice" and not set funds aside for the low-frequency high-cost repairs.

Does anyone know if evictions occur with greater frequency in certain times of the year?

With the frequency of phone number changes that people sometimes make, this has become a challenge for us.

It happens at a much higher frequency than you might think.  

I am also interested in groups that can not be tied to a single location but may meet via a web based medium at a regular frequency. 

Unless you've lived in one of those markets before and really know it well, you're not gaining any advantage by investing where friends and family live - you'll be hiring a PM that knows the area, and you shouldn't have to check in on the prop physically with any frequency unless you just want to.

If my numbers show 33% DTI but the official software says 47% (happens with shocking frequency), I know that one of the two is obviously wrong, and I know this early in the process.

If the goal is the long term play and money isn't a worry, it is more about the structure and content you are going to push (having a plan for it, frequency, content), rather than exactly what company you use to do so.
