Well I just bought a 4 year old brick town house with 3 bedrooms (all with built in robes), 2 bathrooms, double lock up garage in quiet no through road in Seaford for $275K.
I have rented in Carrum and Carrum Downs for a few years now, no way in hell I'd want to buy a house in Frankston North or Carrum Downs to live in. An Investment Property maybe, but definitely wouldn't want to live there.
The street in Carrum Downs where I am currently renting (until I move into the place I just bought in a few months) has really nice, new town houses (to rent or buy), but there are scum bags around everywhere. My brothers car was stolen, neighbours constantly fighting, obvious drug dealings, ppl doing burn outs all hours of the night, cars without number plates arrive at all hours of the night, etc..
They seem to leave me alone, but my brothers and g/f have been harrassed when I'm not around. There will always be nice people and scum bags where ever you go, but for some reason the "other side of the Frankston Dandy Rd" is a lot better area to live. And why wouldn't you buy in Seaford, in many cases costs the same to rent!
