Here are specifics from someone who has lived in Santa Clarita since 1987. First, Saugus is part of the city of Santa Clarita, as is Valencia, Newhall and Canyon Country. Valencia is the prime real estate, with prices to match. It is a master planned community within the city. Unless you're wealthy enough to purchase a very large estate in the hills of Newhall do not live there. It is the worst part of the city. Areas of Canyon Country are gang ridden. Saugus has few rentals, is very stable and low in crime. The City of Santa Clarita, in its' entirety, has been considered by FBI statistics as one of the safest cities in the country to live in.
Two significant reasons for the low crime rate is that much of the town is built with cul-de-sacs, making it difficult to navigate for robberies. Second, many from the LAPD don't want to raise their families in Los Angeles, so they, along with lots of LA firemen live here. Another reason is that we all watch out for each other as a community.
As a single woman, find a suitable home, then talk to neighbors. They're always going to be kind, considerate and helpful to you here in our city.
