Best up-and-coming neighborhoods in Austin?

This question cannot be answered with the provided data. The available data includes only general housing market trends for the entire Austin-Round Rock-San Marcos metro area, not specific neighborhood information or indicators for "up-and-coming" areas.

I cannot answer which neighborhoods are "up-and-coming" because the data I have only covers the entire Austin-Round Rock-San Marcos metro area. I don't have information specific to individual neighborhoods to make that kind of recommendation. However, I can share some insights about the current market trends across the whole metro.
