I'd say that a pretty safe short hand is 3% of the purchase price or less. And I'd consider pre-paid items (like interest on your new loan, insurance, tax escrows) to be separate in most lenders's minds (unfortunately for buyers). But Matt's correct in stating that a mortgage professional will be able to give you the best idea about what the precise costs will be.

Every closing is different. Many factors can change how much your closing costs can be. Your best bet to get an accurate quote would be to contact your mortgage broker. They will be able to give you the best information for your particular situation.
