Deductions & credits

I didn’t see a method to edit my post, but the questions I have are basically how to split all this up. Do we split up the closing costs of 4887 between us? To figure fair market value, which I think would be $15K (based on value of home at sale of $55K and sales price of $70K), do we split that down the middle too and report it that way? It’s confusing when you’re dealing with more than one person on this. Thanks again.
