$500K is still a decent enough budget in Sydney to provide you with a plethora of choice when it comes to housing. From the Hills to Hornsby to Sutherland and West there are literally hundreds of houses on the market right now that would suit your $$$. However, with so many first home buyers obsessed with only buying NEW it seems to me they're missing out on the obvious benefits that established older housing provides ie: land size, established infrastructure, proximity to transport, schools, shopping centres etc
With a little paint and simple renos so many ugly ducklings can be fixed up to look like new and I'm continually amazed that people will sacrifice so many other features simply to live in a brand new home (that in 5-10yrs time suddenly won't be so new...) often with no yard or space between their neighbours.

Second your thoughts on Seven Hills- I've been an advocate of the area (south) you refer to, for some time now. Value for money, walking distance to rail and still close to the freeway.
Along with other suburbs out in the NorthWest and Western region, there are some top spots for first home owners, that represent real value and less pain in the hip pocket. You only need to look further north along the Seven Hills railway line (Richmond) for value for money- many suburbs with freestanding homes within walking distance of the station in the sub $400K price bracket.
Sydneysiders who are serious about finding affordable homes need to get out and about more, and discover these areas for themselves, perhaps sacrificing the media room, 4beds and DLUG on 400sqm for an older but smaller first home buyer abode on double the amount of land. Then, when time and debt reduction have run their course, upgrade to something bigger, just like several FHO's have done before them. At least get a foot in the door, because Sydney now, in many suburbs, represents a great time to buy, in my opinion.

Agree with your thoughts on units in premium positions within these suburbs. For the LNS, also consider Waverton and Wollstonecraft, even Artarmon, given the huge benefit of rail (that Neutral Bay, Cremorne and Mosman lack) and also proximity to the CBD and lifestyle generally. I also like Greenwich, St Leonards, Naremburn, Crows Nest as well for the same reasons. Wonderfully located, close to trains, buses, cafe society etc.The entire North Sydney area is in high demand for tenants and you're right about the rising rents. A budget a little more (up to $550K) is going to get you something better in the 2bed department, if that's what you're keen on. However, 1bedders are just as rentable, in demand and can be significantly cheaper (by up to $100K) so also consider these as well if you're purchasing for investment. There are more one person households in Australia now than there has ever been; something to keep in mind.
