Help! Stumped on Colorados Contract to Buy and Sell!

With 16 pages on this, lots of unnecessary stuff. But line 144 what is the difference between "Due on Transfer-Strict" and "Due on Transfer-Creditworthy"? And as an investor which one is better for me?

Also line 57 it asks if Buyer will/will not provide a mortgagees title insurance policy. Since its a cash deal, do I just say 'will not' ??

Any other hints for me to cover my butt???

Thanks in advance all!!
