"I always thought the outer as in regional were last to boom , theory being inner city or close to city rose first and money spread outwards until the outer burbs got so dear then money hit the regional centres causing them to boom"
Another theory is that as inner city rises, 2 things happen. Yields fall (because prices have gone up relative to rents) and rates rise (to take heat out of the market). Yield investors keep moving outward until they find the yield required. But they are a small percentage.
One is perception of value, the other is viability of return.
Regional is last to boom, and last to fall (usually, because it's yield makes it self sustaining and prices don't have as far to fall to return to the mean)
