I think I just fell in love with this logo! A circle broken into 4 parts ( group) the cirrus clouds also represented, but this time they are more direct...more agressive. The sphere sits slightly higher above the text to create the illusion of movement within the design.
Here is a version with buildings incorporated. I used 3 for the 3 partners. Looking at all the logos here, I wouldn't know that you were involved in real estate, so I included this one just for you to have that option.
