Austin mid-range in expansion cycle?

[Marian Smith]

"Despite the fact that thousands of units of apartments recently have been completed and thousands more are under construction, Integra believes there is still plenty of room for additional inventory. Austin is right in the mid-range of the expansion cycle. Investor demand also drove prices in the multifamily sector up 43 percent year-over-year in Austin. Integra notes that the high wage earners in the tech sector are driving the persistent demand. Prices are up about 29 percent in another tech hub — San Jose but down substantially in Boston."

Quoted out of Austin Business Journal.  Does anyone know who Integra is?  

I know no one can predict the future....but the RE cycle graphs I have seen show the expansion cycle overshooting demand and creating a downward trend.

43% sounds like a lot.  I guess that could mean a higher class of properties dominated sales.
