I like where your head is at with these designs. I was thinking about possibly have a design where the P and F are both laying flat, forming the bottom of a home where the round part of the P and the prongs of the F meet to form a doorway perhaps?
Also, maybe you can try something which outlines the Flow, the process, of buying a home which our site is trying to create.
I like your new version #33. I think perhaps the "P" needs another element around it instead of a roof on top of it. Please reference entry #45. I am not in love with #45's "hoops" but something that shows fluidity and movement. Also, I think it makes sense to have the "prop" and "flow" text the same size. I know previously I said do them differently, but based on feedback, they should be the same font size. Thanks!
