In this decade, with all the available technology... use a whiteboard? Yes! A dry erase board is an easy way to help organize digital photos during the home search. Before looking at the property, write the address and list price on the whiteboard and take a photo of it in front of the house. Write "must-remember" features on the whiteboard and take another picture.
Home hunting gets confusing. You'll be surprised how this can help sort out a day of having seen 3, 4, or even 10 homes.
