This hint relates to the foyer space:
This is really your first impression of your home. Make it as inviting as you can.
Less is more in this case. Do not have extra table, chairs, coatracks and shoes out to see.
Make sure the woodtrim is painted, the staircase is in good shape and clean the carpets on the stairs.
Have a new door mat to welcome the Buyers.
And as always a mirror is a nice touch, along with a decorative shelf and fresh flowers.
