Okay here are my personal thoughts and preferences....
1. I think personal and caring is good because you're exploring a huge decision
2. I think photography is a huge thing on this type of site. I recall thinking "there's never enough photos...only floor plans." It's nice to see as many angles as possible before deciding to take the time to travel to view it.
3. Why not have the music going? People have the option of turning off speakers.
4. It's nice to hear a realtors background in a concise and not too wordy way.
5. A links option is nice...you can look if you really want to but again, it's just a personal option.
6. Warm is homey....so that would be my choice.
7. A lot of photographic options....you can really shop better that way.
