Hi Christina, the usual escrow fees are $325 base and $170 per $1,000 of the sales price. It varies between escrow companies, but this is the usual standard that we see. "Seller to pay closing costs up to $11,500" means that the seller is paying up to that amount of the buyer's closing costs. The seller will have their own fees, such as the comission and escrow fees, in addition to the $11,500. The buyer might have - for example - $20,000 in closing costs - and they would be responsible for paying the difference. The term "Escrow fees 50/50 split" means that buyer and seller has their own escrow fees. As for what those fees are for, I sgguest you contact that escrow company and ask them straight out. I hope this was helpful - I know it can be confusing, and I wish you the best of luck with your sale.
