Second take: I thought the call for attention should be the For Sale stamp. My initial sketch with this approach left too much negative space to fill the inner circle shape I wanted until I thought of using a graphic. (Also, I found Futura LT which includes more weights.) The supposed icon (described below) ended up too detailed so it's a work in progress. Also the 'For Sale!' text is now protruding out of the inner circle which was my original goal but it's placed lower than the vertical center to make room for the icon. But more importantly the visual hierarchy of information is in order.
