I have been a lurker on this thread for ages now, and have read through it repeatedly.  

The easy, low hanging fruit.  

I considered that house to no longer be "low hanging fruit".

Your budget looks healthy enough to produce fruit, but without knowing any of the specifics, I really can't comment.

And while @Michael Quarles is correct in that direct mail is only one source of great leads, it is...IMHO...the lowest hanging fruit, where you will get the most bang for your buck.He also speaks of key follow up systems including text, chat and email (like Calltext.com). 

From what I have read here and what I am starting to understand is that as your marketing budget increases (number of units mailed increases) the more one goes for the lower hanging fruit.

As for agents, I do have a license (and so am trying to navigate the terrain of doing both) though I primarily want to wholesale.

Farm - A farm is not fruit and vegetables.

Those are the low hanging fruit.

Defining your enough can be a good measuring stick to reasses, because spending time on forums like these you're likely to hit your enough, the key is being able to say "I have enough" and be able to enjoy the fruits of your labors.
