The "HIghlands" neighborhood is a large one , probably the largest neighborhoood in White Plains
Overall, it's my opinion that the Highlands is a sought after location, has wide range of house prices and has an active neighborhood association.
Grandview Avenue is located in the middle of the Highlands neighborhood.
There's a Church on the corner of Grandview and Bryant which can generate additional traffic and street parking in the immediate area. Some people have a problem with this, others don't.
I've lived in White Plains my whole life and have never heard anything bad about Grandview Avenue area.
Google's street view mapping application is now available for most parts of White Plains. I've provided you with a link to the area on Grandview where the church is located. You can (virtually) drive up and down the neighborhood streets to get a better feel of the are. http://tinyurl.com/6xcogg.
