The costs are negotiable, it depends on how your contract is written.
That being said, in some counties it is traditional for buyers to pay the title work, in others the seller traditionally pays it (exception being the buyer's lender title insurance & related endorsements, which is typically paid by the buyer).
Doc stamps on the transfer of title are traditionally paid for by the seller -- however, on bank owned sales they often specify that buyer will pay the doc stamps.
If a buyer is getting a mortgage, there will be doc stamps and intangible taxes on the note and mortgage, which are considered a buyer expense.
If your real estate agent is using the FAR-BAR contract form, these expenses are addressed in the contract.
