One thing that stuck out to me about the other place (only looked at the first) was the parking. I think your place looks nicer overall. Also, back yard of yours nice? That was one of their pics.
As far as the pre-pics...I'm not sure...I guess I'd have to say it would be nice to have if someone asked but if not then they don't need to know what it used to look like. That might give them the thought that you bought it cheap and try to bid lower...but then again...I'm not a realtor, I don't even play one on TV. Seems your right in the sweet spot on price though.
