If you want to make an offer on a home in Florida, you can write it on anything you want in any way you want. As a realtor, I cannot use anything other than the contract form provided to me by the Florida Association of Realtors, or I am practicing law without a license. But, if you buy a home where you and the seller have agreed to the terms in writing, that is entirely up to you.
I would ask, why would you do this. By using the FAR or the FAR/BAR contract, there are many built in protections for you the buyer and the seller. Why you wouldn't want these protections is beyond me. Furthermore, as the buyer, you don't pay anyone--the service of a realtor is FREE!! The seller pays the realtor the commission--part of the LISTING agreement. I can't imagine why you would do anything else. The realtor has access to the best information and personnel to help you through your transaction, from loan officers that have done good work for them to title companies who are going to manage your transaction through to the closing.
Not using a realtor to buy a home just doesn't make good sense financially or legally!!
