Buying Contract Opinions and Options

Hello all,

Lately I have been searching for a buying and selling contract. However I have a few questions.

  1. Is this the same as a warranty deed? Does a warranty deed break off into other subtypes? I think I have heard of a limited warranty deed.

  2. If this is true what are the differences?

  3. I have seen contract packs at Office Depot. Are these any good for investing? Can I make copies of them?

  4. Is there anywhere else i can get a good contract?

Thanks all!
