You can learn to write contracts, etc through the classes.

Make it part of the contract...it serves both the contractor and client well.

Would love to get some schooling from you more experienced Pro's out there on the best completely legal and ethical way to structure this.

Some of those that you consider as competition might be nice to you.Always do the math analysis and try to look at the prospective property before you make an offer or at least have a clause in the sales contract that allows you some time (probably about 15 days) to make a detailed inspection and possibly back out of the deal without a penalty that will hurt you too much.  

From signing the contract to closing title I try to have the house purchased within 30 days.
