Hi Justine
I think it's great that you have the time and energy to search for yourself but do make sure that you follow the tips of those here before you, especially the wise words of Player, Prop and those who've bought in the area. As you know
only too well, I've purchased for many clients in the Parra region and can at least offer comments on Bill's links above (if nothing I can at least save you some time traipsing around to the wrong properties!)
1. Bowden St in HP is ok but this end does suffer from exposure to the nearby M4 noise. It can also be a visual deterrent.
2. This one in Good St is actually on the corner of Bowden and suffers the same as 1. Been on the market now for a long time.
3. The other side of Wigram St is my preference as this side backs onto the rail line and doesn't have as much "ambience" as the other side. This unit is also very very small and in poor condition. Trust me on this
4. Not my preferred part of Westmead as there's a lot of complexes in competition with one another and anything under $400K here usually has a downside (large complex, busy position, poor floorplan, lack of secure parking etc) It also backs onto the Cumberland Hospital site (not everyone's first choice)
Bill is right, in that there is currently good competition for the lower priced units and those of good quality tend to sell quickly leaving little room for negotiation. As others have said it's IMPERATIVE that you know your values, have access to the latest sales data (please don't rely on the agent to give you this) and select the right complex. They are certainly not all equal.
A strata search is a must before going unconditional with any contract, and remember that here in NSW it's considered standard procedure to exchange under a cool off and perform your DD during this period. However, you need to be smart here and ensure your terms are accepted prior to exchange, preferably have a strata search underway (if not complete) and obtain a written rental appraisal from a PM so you can ascertain your likely yield. Also hop on realestate.com.au to check out current rentals in the area.
Despite what Evan believes, its my humble opinion that local knowledge is not something you can pick up over a few weekend visits so read read read as much as you can and ask those before you questions of the area. Knowing the individual agents and their "modes" of practice can also be highly helpful
however feel free to shoot me a PM if you come across a tricky one and I may be able to assist with my "professional opinion" here. Best of luck and happy searching!
