If you want to, you can ask the sellers to provide a home warranty in the deal. They can either accept or refuse your request.
Once everyone has agreed on a price, there will be a contract to sign. Make your offer contingent on the house appraising at that price and the inspection being to your satisfaction. You’ll sign some papers, choose a closing date, then your realtor will help you with the next step.
Appraisal - It is the buyer’s job to get the appraisal, and this is a requirement of the bank. A professional appraiser will compare the house in question to other houses in the area to make sure you are getting a fair price.
Inspection - This step is up to you, but it is highly recommended. Hire an inspector to check the house over for things like wiring, plumbing, and structural soundness. If the seller has listed the house "as is" then you will not be able to ask for improvements. If there are many problems, it's better to find out now.
Closing Date - When the time comes, you and the sellers, along with your realtor, will meet at the title company to sign a WHOLE BUNCH of papers. I’m not even going to go into what all you have to sign - that’s what your realtor is for. Once all the i's are dotted and the t’s are crossed, the house is yours to move into!
