I have sold three properties of my own and also my parents house when they died. Although all the properties were different and each was targeting a different type of buyer these standard items always worked so my houses sold faster and for a higher price than my competitors (I sold in city, suburbs, commuter belt and country village).
First declutter - hire a skip or a mini ship and get rid of everything you have stored in your shed and in your spare room and random cupboards (people do open drawers and check all storage cupboards and if yours are full, they will assume there is not enough storage for the size of the house).
Second - depersonalise.
People need to be able to walk in and imagine themselves living in the house. Therefore remove all but two to three photos - you need some life in the place so it looks lived in but not enough to prevent people seeing their furniture and photos in the place.
Third
Clear out the garden front and back and make sure the front of the house is clean and tidy - get rid of bins from the front area.
Fourth
Go around all the house and see if you need to repaint any walls or woodwork - if the paint looks shabby, unless your house is an executors sale, you need to paint it or touch it up.
Fifth
Clean, clean and clean again - your house needs to look like a show house for each and every visit
Sixth
Have fresh flowers in the kitchen or dining area - at the kitchen table.
On the day of the photos, review them all with the photographer before they leave and make them redo photos if they do not look good.
All the items you remove of yours like photos should be packed and stored away ready to move to your next house (and they might even spend the next decade in the box, if, like me, you forget about them).
