Who are "they"? If you have a written contract executed, you should have everything covered.
Your realtor would have the answers or find them out for you.If this is a foreclosure and they accepted your offer in writing, they know, that they would have to make the place pass FHA appraisal( if they did agree that your offer consist FHA finance)
Without knowing details and see the signed contract, it is hard to answer your questions.
It raises more questions than give answers.
