Actually, there are key items in your 'aside from.' Take the deep cleaning to the max. We have experience with selling four in one area on very short order. Potential buyers and agents commented on the upkeep and cleanliness. This doesn't mean hospital-like walls, floors and counters. It was from getting out spider webs from gutter corners, shutters, fixing cracks or places were there were gaps. Ensure room corners don't have pet hair build-up and drains are only chrome-on-porcelain (no rust, crud, black stuff). Grout should be white, everywhere. Caulking around toilets and moldings not all dusty or clumpy. It will take work. Of course the aim is to maintain your home like this in the first place... live this way and I believe that even odd-colored walls become a moot issue for the potential sale. It's the skin and bones that matter and not so much the makeup. IMHO.
