oh the laundry sheets would have caused me to leave even if i loved the place-my eyes start swelling from the scent of them, same with scented candles. i would go for a "clean" smell (or the old chocolate chip cookie or apple pie scent).
i don't think you indicated that you have tile floors, but anyone with them who is selling consider hiring a clean-up (not housekeeping, more like servpro or others that do fire and water damage houses) company to clean the grout. i do my best to clean up spills but 6 years and 2 kids take their toll. i have no problem toothbrush cleaning tile counters but a large kitchen, entry way, 2 bathrooms and a laundry room-it would have taken me weeks (and weeks to recover

). i treated myself to hiring one of these firms last spring, they sent in a crew who got down on their hands and knees-my floors look new again-the best few hundred dollars i ever spent.
most shows strongly encourage you to invest in new bedspreads at least for the master bedroom (makes it look fresh and more inviting), and some go so far as to say if you plan on buying new furniture when you move to buy it before you sell to give a more appealing/updated appearance.
i'm not personaly put off by family photos, i'm looking at the bare bones of the house and the floor plan. i am put off by the potential of having to pull down wallpaper or paneling (you never know what lurks beneath

), so removing wallpaper and painting or drywalling over paneling can increase the appeal esp. with an older home.
because our current home is realy well insulated and our heating/air bills are lower than norm for the area i am saving utility bills from this past summer and will for the winter to have available for review because i know this will be a marketing element when we sell (it could be the greatest house but if the utility costs are too high it would knock it out of consideration for me).
