You could probably get it for less if you negotiate well.
19 Fraser Street Rosebery Tas 7470 - House for Sale #114239035 - realestate.com.au

or if you want an uninterrupted place for a dirty weekend then this little hideaway in country Qld should do just fine at $20,000
Rubyvale address available on request - House for Sale #114600987 - realestate.com.au

or live in airconditioned comfort in NSW for $22,000 (Sydney eat your heart out)

or in beautiful and sophisticated downtown Norseman WA for $25,000

you're too late and you've missed out on this Mologa Vic house for $30,000

and you have missed out on this two bed two bath unit in Surfers Paradise that went for a little more than just $50,000. I think that Penny said it sold for $80,000 at the auction bought by some rich bastard.
