If you're in a market where houses sell very quickly, I wouldn't bother renovating--just clean and declutter. Consider as well the cost of the time delay involved in renovating vs. getting your house on the market sooner.
Realtors generally have a stable of "professionals" who do kitchens, bathrooms, decks, landscaping, painting, etc. They have to feed these guys on an ongoing basis in order to get their own house (of latest flipper house) fixed/upgraded at the bargain rate they will require in exchange for all the referrals. My point is that there are market forces at play here that have nothing to do with your house or the buyer expectations in your market. A realtor will sell your house once but will interact with these contractors time and again over the years.
We recently watched a neighbor plow an easy $50k (maybe much more) into kitchen/bathrooms and landscaping on a 1950s split level. It looked very nice, and may have added a little to the value of the house, but the increase can't have been as much as they spent. Ironically, the buyer tore the house down to build a spec yuppie mansion which sold for over twice the sale price of the split level. We did notice the new kitchen cabinets and fixtures were carefully removed, presumably for re installation elsewhere.
