Park View transacted price trend

Recently my friend is looking for 3 rental units at Park view.
I send out the notification to all my Park view unit holder.
Two of them rented out successfully for $1500 per month.
This is real good rental yield.
If based on the purchased price below, the minimum yield is 6.1% and maximum can go up till 8%!

Table below is compilation of my circles of friends who own the Park View units.

We started to scout this area since last May 2013 with the initial $220/sqft. The highest purchased price is peg at $330/sqft. The appreciation is 50% for the past 18 months!

As such, it will be still a good potential for this area for the upside.
