Unsold completed terrace end-2018

We were looking at pricing for completed-remains-unsold terrace houses across the country as of end-2018.

We found that half of unsold terrace houses in Johor are priced more than half a million.

In Selangor, similar pricing is the most overhanged. On the other hand, Penang has very low of unsold terrace.

We are curious about Kedah and Perak. Any idea how that have sizeable overhang in terrace house?
