Staging is vital and we (Weaver Realtors of Storm lake Iowa) stage every property we list to some level. Most people think staging is for inside the house but I beg to differ. If you don't have good NO GREAT! curb appeal in this tough market you won't even get a buyer in the door!
This is how we do it - Clean, organized, reduced to the point of sparse, no pets, no pet smells, no smoke smells, no food smells, Plastic tubs for extra stuff, neatly stacked about 3 high in an unobtrusive area, this gives you the jump on being organized in the new place when you move. Reducing and cleaning will aslo make you feel like you just lost 10 pounds.
This is a good article on staging if you want to help someone or if you are thinking about selling. http://bit.ly/daAgyc
