I currently work at ReMax Leading Edge in Gambrills, Md. I have seen the same trends in our marketplace as well.

One of the items that I found that I wanted to add in our area was instant text responses when people drive past our listings with the ability to follow up with those interested parties. I was surprised when I wanted this that nobody seemed to offer the service about 16 months ago. Together with a partner, we developed a service (originally I wanted it just for personal use) however due to the market trends and the fact that we deal with Buyers from all over the country, we decided to develop the service with national coverage ability.

As another agent who appreciates technology, you may find it interesting and a compliment to the marketing that you are already doing. http://www.texttoknow.com
