See now thats a different thing altogether and one I could agree to.
Have an inspection report available to all prospective buyers....
But if an agent came to me to sign anything other than an OTP after they've got a mandate on the property (and not sole) they would get told to get monumentally bent.
Generally a condition report declaration is available prior to but at the time of signing an OTP and any additional inspection clauses/conditions will form part of the OTP. It's prudent to do this as it generally protects both parties.
