How many neighborhoods do you target?

[Eric NA]

In reading a book, it indicated that you should target around 5 neighborhoods. This seems like a low number to me, and I intended to target around 10+ neighborhoods, but I want to know what everyone else is doing.

It makes sense to only target areas within your city you can easily get to, or don't mind getting to on a daily basis. So how broad or narrow is your particular focus when looking for properties?
