Buyer protection is by reviewing the home carefully before writing the offer followed by the proper inspections during an inspection period.
The Arizona Association of Realtor contract frequently used provides a 10 day inspection period in it by default.
Of course your Realtor should be the one answering the question as that person should be the one that knows what you signed or plan to sign.
When you write the Offer, you put in a CONTINGENCY FOR INSPECTIONS, and include enough time to do all your Inspections.Then, even if it As-Is, you can walk away from the deal if you find something that is too much to accept.
You always want to include that, as well as Contingencies for Appraisal and Loan.
Good luck and may God bless
