Just one parting comment regarding that Asbestos Siding. I'd paint it. It is usually a problem to dispose of, and the stuff is so hard (it lasts forever), Siding over it is going to be costly . . . . plus a Buyer may think you're hiding something.
Everything else you mention sounds reasonable . . . . or generous. I'd focus on whatever will enhance the Curb Appeal; and avoid making it perfect. You're finished with it, pass along a good price and let the next person do it their way !
P.S. The now defunct Asbestos Mines are here in Vermont about 25 miles to my west, scaring a mountainside.
