Paying all seller closing costs & contract language

[Adam Roberts]

Team -

I'm in the midst of getting a SFR under contract in Keller, TX area and seller has finally agreed to my price in exchange for me paying all of their (seller) closing costs. Basically they named the price that they want to walk away from closing with and expectation is I cover the net difference.

My question is this: while I am pretty certain that the closing costs will comprise of the typical costs (attorneys fees, title fees, etc), should I be protecting myself from any unknown closing costs that may be a surprise when I get to the table, by way of language in our written contract? I have never been surprised by this, but it seems like something that could be an "unknown" when I agree to pay their closing costs "in general".

Thanks
