Demand to Supply Ratio - the gap in supply and demand. The bigger the gap the higher and sooner prices should increase. The reverse is also true. The score is the single number we apply to this measurement of supply and demand imbalance. The score is also useful for sorting the thousands of suburbs you might want to consider from high to low. You should be looking mostly 'inbetween' as too high a score means bargains won't be available but also a low score means you might pay less but not enjoy a good investment return. Make sure you read our YIP magazine 9 part series on the DSR Score. It's available in one downloadable booklet.
