Unless you are buying a new house with warranties on most equipment, it is highly recommended that you get a property inspection, a roof inspection and a termite inspection. This way, you will know what you are buying. Inspection reports are great negotiating tools when it comes to asking the seller to make repairs. If a professional home inspector states that certain repairs need to be done, the seller is more likely to agree to do them. If the seller agrees to do the repairs, have your inspector verify that they are done prior to close of escrow. Do not assume that everything has been done the way it was promised.
