Perth market has done very well in the last few years due of course to mining boom and resultant skills shortage bringing in high skilled & well paid migrants.
I remember when I arrived in sydney in 2003,Perthsiders telling me how cheap property was in Perth compared to Sydney.
How times have changed with Perth now the 2nd most expensive city in Australia and now less than 10% behind Sydney.
If the mining boom continues then your investment will pay off.
