Know-How Exchange : Branding

As a new team, consider specializing: starter homes, historic homes, rural properties, fire-safe properties (a tie-in with your husband), senior-accessible homes (a tie-in with your background), etc. Don't worry about branding, social media, etc. until you're clear how you will distinguish yourselves in your community.

The first step should be figuring out what unique and compelling benefit your clients will realize when they deal with you. There must be a target audience perfect for what you can do.

Without a clear and specific definition of your target audience and the benefit they'll realize, you are just playing with words. Better if you go for communicating the essence of your unique benefit promise.

Branding advice, tag lines, and social media advice. That's a lot. Break it down. Where do you want to begin? What do you want to achieve? What's your timeline to accomplish all this?

Have you gone through your colleagues tag lines and boiler plates. There - and on competitor's sites - there are an abundance of good touching presentations. Don't waste your energy here: just "clone" from the best.
The real issue is to differentiate your dynamic duo. With that kind of background I'd put "SAFETY" as #1. It's almost like falling in love with your new dream home, but there's always a risk banging behind your brain. Write customer safety at the center or big blank paper and then everything related to new home safety around it: capital risk, value sustainability, neighbors, home tech, building materials, mold, ...
Then look with your professional background what you can tackle better than anyone.
BUT remember real estate is social network game. The wider the network, the larger the deal flow.
