Assigning an Assignment

I know this has come up before, and I know it can be done.

My main question is the wording.

The first paragraph is the main paragraph I use and would be the deal being assigned to me. The second paragraph is the same paragraph, but reworded slightly. Is this the way to do it?
Advice appreciated, I have a buyer lined up for this one who I will hopefully be meeting tomorrow.

I noticed you did not receive any comments on this assignment contract form you created. Did you use it after all. If so, how was it accepted by seller? Did it pass as one that could be legit? I am new to all this and just looking for all ideas that have been acceptable.
