Again, as long as the house isn't a short sale or being sold "as is" then whatever repairs the seller agreed to make before they should still make. They are also responsible to fix any structural damage (i.e. fire damage) Insect or termite damage, and heating.
Most things you can use to bargin. Anything minor-very minor, you usually have to do yourself.
Also if the seller refuses to make some of the repairs, again depending on what they are, you also might be able to get the price down based on the cost of the repairs.
Also under FHA guidelines the house has to be cleared so often they will send there own inspector depneding on the damage reported in the inspector's report. I would talk to yor mortgage broker to find out what the guidlines are.
Also as long as your agent calls back within a 5 hour period, it's cool, if they are taking like days to get back to you I would be concerned. School just started so I know here in NY the market is picking back up and calls get start pouring in.
Good Luck! I hope everything works for the best.
