After the 6th question we fall to a longer script however we use the short version to get non motivated people off of the telephone. 

Is this the BiggerPockets version of Ginger vs Mary Ann?

Well for the post here I gave you all the short story of how it's done.Full version is that people opt-in to receive free information every two weeks on how to keep their lawn healthy.

It would be very difficult to run a test of 20 bandit signs with individual phone numbers, with slightly different sign designs to calculate what version of the sign works best, and which of the 20 unique phone numbers (representing a unique area the sign is placed) increases the conversion rate, The variable of signs being removed makes this even more difficult to know with a high degree of confidence. 

The latest version was entitled "How I turned $1,000 into Five Million In Real Estate."

The old hardware store in my neighborhood still sells a "new and improved" thin plastic version .

. :) That was great advice and I had debated making the letter shorter….or even longer and sending along a summarized version of my investing resume (which is short, honesty) along with the terms I am proposing and how their money would be protected (first position, reasonable ltv, insurance, automatic monthly payments deducted directly from my checking account, pre-signed deed in escrow so foreclosure proceedings could be avoided in the event of default, etc.).

And I am translating the entire thing in to a spanish version as well.

We opted not to use a typed version, only the two handwritten that I attached.

Since that is my strategy, I'm trying hard to come up with follow up letters that don't sound too "professional-like".Here is a (basic) version of what I have so far:Letter 1: We are interested in buying your house.
