just googled the place, one of my friend use to live in that area. Here's my $0.02
1, Yes. very expensive if all use elec
2, Depend on which side it faces.
3, It's a relatively safe place (west of 152st is bad). It's not very close to the mall.
4, Schools are bad for that area.
Additionally, 5. this place is very close to the high way 1, be careful about the noise.
1+3+4+5 = NOT a good location.
