Things into storage that you don't need, neutral colours as much as possible, no personal stuff around (photos, ornaments etc put away)
Yep all that is great.

Declutter, then declutter again. Most people don't realise how much stuff they have until a real estate agent comes in and says "get rid of it all", LOL.

A really nice bedspread with some throw pillows can lift a bedroom from drab to fab, just make it light so it makes the room appear bigger. We put a plain coloured sheet over a yucky dark brown couch and added two scatter cushions and it looks kinda funky instead of "omg that looks like a mashed banana stain".

Sugar soap the walls if you can. Get a professional real estate photographer.

Get rid of all your rugs, it makes rooms look smaller than they are.
