#4 i would like to see some sort of reference to a house used in the logo. Colors are good but please make sure they are solid and not a fade. #6 not as much of a fan of this one. still the same comment as above in reference to a house.
ok, i really like #7! let's see it where the windows are incorporated into the R and the B. i would also like to see the roof color match the properties color.
