Hello, #3 is a no go. #2 I like the lettering and wave on this one but can't seem how I would be able to incorporate and advertise with the bird for future real estate listings.
#1 I like the houses, boardwalk background and water. Don't like the palm tree since I can't incorporate it in our area. I like the wave but would like it to be more visible.
take a look at these. I like the lettering and color on this one

http://99designs.com/logo-design/store/26033I hope this helped and hopefully I didn't mix you up on things. Just trying to incorporate sand, beach, sun and real estate into one thing if possible. I want to go after outside buyers from Silicon Valley and I know that many when they think of Santa Cruz, they think of the beach boardwalk or beach first.
