Self-preservation when submitting an offer without seeing a property?

[Jon Huber]

I am putting in an offer on a property I know to be a great deal. However, we all know a great deal on paper may not be a great deal in reality. I won't be able to actually go and see the property for at least a week, and the great deals in life never last that long. Besides a home inspection clause, what other "safety nets" can I use to protect myself to be able walk away?
