Remember one thing, you do not get what you expect, you get what you inspect. You are purchasing the largest financial purchase of your life, and to not know what you are purchasing leaves you open for having very expensive future repairs to your home. You do not know what you do not know. If you have to negotiate without an inspection contingency, I recommend that instead of waiving your inspection, negotiate that your inspection is for your information only and that you will not ask for repairs, but have the right to walk away due to negative inspection results. What I have found on inspections have many times surprised my clients. They have admitted to me they would not have known and the cost to repair would have financially difficult.
