(Meaning you can control real estate by buying an option to purchase it later and exercise the option when the time is right)

Then while passing out the Business cards write who the person is on the cue card. you'll find that when you go out of your way to actually accomplish this exercise buying houses will come very easy.

I learn a lot from books, but hands on exercises and games I get more out of. 

Let's look at WHY - WHY you want to get involved in the mailing exercise ---- TO FIND A DEAL AND MAKE MONEY?

The we let out client pick 3 favorites and see them in person as an educational exercise, not to write an offer. 

In the event Seller is unable with the exercise of due diligence to satisfy said objections within thirty days after said notice, Buyer may, at Buyers option: (i) extend the time period for Seller to satisfy said objections, (ii) accept title subject to the objections raised by Buyer, without an adjustment in the purchase price in which event said objections shall be deemed to be waived for all purposes, or (iii) rescind this Agreement, whereupon the deposit described herein shall be returned to Buyer and this Agreement shall be of no further force and effect.

I understand sales process exercises like scripting, overcoming objections, take-aways, and all of that.  

As a wholesaler myself, I think I would rather go with "Cash For Houses" approach. for me I am up front with my intentions and if I choose to buy then I already have that in the contract so I exercise that option.

All rights, powers, options or remedies afforded to Buyer either hereunder or by law shall be cumulative and not alternative and the exercise of one right, power, option or remedy shall not bar other rights, powers, options or remedies allowed herein or by law.

You will definitely learn a lot from this exercise and I recommend all new investors do it.
