How to Write an Offer with Contingency for Idaho?

[Matthew Netwon Marquess]

I'm wondering how do you write an offer with contingencies' for an investment property?  I'm looking at multifamily properties in Boise, Idaho and my Real Estate Broker said that I need to make an offer in order to see one of the properties.  I tried to find a template to follow but struck out.  

Also, what exactly would I put in the contingency to make sure I get out of the deal if when I walk through the property I don't like it?

Thanks!
