So I am thinking of buying this house, which the owners converted the garage to a rec room. I will want to convert it back. The window, trim etc, is put over the existing brick. (the brick was not removed during conversion). The owners built a subfloor inside to bring it to finished floor height. I am not sure what they did with the garage headers as its got drywall for the ceiling.

What kind of cost am I looking at? I am in the Nashville TN area. I figure the door, for a Lowes basic one is $300. Garage door opener, $250. Do the rails come with the door or are those seperate?

I am good at demo, so feel confident I can get the window and wall portion out as well as the subfloor. What am I looking at for the garage door and opener installation?
