I’ve used Room Snap on several houses now, even on houses that have had professional photography. I’m blown away by what I can do with my iPhone. With a professional photographer, you’ll definitely get a larger image, but comparing them on MLS and listing sites where people are looking on their phone, tablet, or computer YOU CAN’T TELL THE DIFFERENCE! I’ll be using this app to get my listings up faster, even when I use a photographer. Highly recommend trying this out!
