Since you didn't indicate the exact wording used we can only assume your agent did not use the wording "seller shall pay $XXXX.00 toward buyer's cc, pp and credits as allowable..." Here are some things you should do:
You or your Realtor should talk to the Escrow agent and ask how they are 'required' to handled it the way its written in the contract. From there you will know how to approach the seller regarding any remaining funds. Depending on the type of loan you have, you may be able to have the remaining funds applied to some of the prepaids or to have your interest rate bought down a bit. Your mortgage broker should be able to tell you if they can do that and should have suggested that to you. Check with all of these parties Escrow agent, (as described with the question above), Mortgage Broker (to ask if the loan will allow the extra funds to buy down the rate and cover pre-paids), and your Realtor (to request any needed changes to seller in writing right away). You may, as some of the other agents mentioned, ask to have some applied by seller providing a Home Warranty as well. However, because the negotiation peiod is already ended this will have to be approached very diplomatically because the listing agent will be representing the best interests of the seller and it would seem pretty obvious that they are pleased that they may not have to put out all the money written into the contract if your agent didn't word it to be all inclusive. Best to you!
