One thing you should always do when selling your home is take down your family photos. Buyers have a hard time picturing themselves living in your home when they are reminded of the family that currently lives there. You also don't want them spending their time focusing on your photos rather than the features of the home. Pretty sure you'd prefer they were checking out the awesome fireplace rather than commenting on Uncle Harry's flowing locks.... ;)
Agree? Ok, good!
Now here's a solution for you if you have family pictures hanging on the wall. Rather than taking down the frames and replacing it with artwork, just add some scrapbook paper or fabric in place of the pictures. Instant artwork, and you can leave all the pictures in the frames for you when you move.
Here's what I did in our place when we listed...
I kept all the pictures in the frames and just put scrapbook paper that tied in with my decor over the pictures....
Quick fix and won't cost you a new piece of artwork :)
