First American Title has a fee calculator that can give you an estimate of their fees, as well as some standard closing costs like transfer tax and recording fees for your county. These fees obviously only apply if you use First American as your escrow company. I like them because they provide great service, they're competitive, and they don't tack on a lot of additional fees; their pricing is generally all inclusive and straightforward.
You will have to choose sale type - prices will vary depending on whether there are loans involved or if this is an all cash deal.
You can adjust the estimate based on the what percentage the seller is paying, and what percentage the buyer is paying, according to your contract.
