If the rooms need painting

paint them pale cream/magnolia.

If you have loads of clutter/ furniture that you want to keep but don't need all the time, think about renting a self store unit.

Keep fresh flowers around

Hide family photos - anything personal - this makes it look like YOUR house - your viewer wants it to look like THEIR house to be.

Keep the grass cut and garden tidy - make front door welcoming and tidy.

Clear hallway so it appears spacious and easy to walk through - hide pile of shoes/coats/ bikes etc
