So how do we get rid of the reflections on the windows?
Separate exposure for outside with lights from inside off and just mask/blend in photoshop?
Ceiling fan, on or off?
Good looking stuff, I wouldn't worry about the reflections, in my experience this kind of work doesn't pay enough to warrant that much post work.
Since you're asking, it's relatively simple you take your frame with lights on, and take another immediately after with same settings, with all interior lights off. Stack the layers in PS, and brush in the layer for the windows. If it gets too dark, you may need to take a different exposure, and replace the windows entirely. In this case, you'll need to use the pen or polygonal lasso tool to outline the window, make sure to feather the selection a tiny bit, and then bring the new exposure in.
Your compositions are all pretty good, but think about shooting less wide when it makes sense. The exterior is nice, but doesn't need to be that wide. Realtors generally want the widest interior images possible, so these should thrill this client. Shooting super wide can distort the space, and often doesn't capture the real character, sometimes you need to go tighter to get that. If you ever intend to do interiors beyond RE listings, this is important to understand and implement appropriately.
Also your yellows are electric, so I would either color balance some of these more on the cool side, and/or desaturate the yellows to some degree.
