I hate to pull you up here but that's not true at all. With just 41 transactions it is very easy to find the stats. I took only 10 mins.
The fact is most of them recorded on average 100-150k gains over a 4-5 years period. And that is gross. I will argue that that is in fact not very good at all.
Add to the total 4% subsale/resale figures provided by Newbie bro, you can form your own conclusion.
100-150k within 4 years is pretty decent imo, let us compare this to Eight Riversuites (RCR relatively same walking distance to MRT as SUO) and the most outstanding proj High Park Residences (just taking transactions from the past 6 months as I am a non premium subscriber).
Eight Riversuite (purchased in 2012-2013 sold in 2020)
8 positive resale transactions ranging $8-$124k v 1 unprofitable transaction $111k loss
Sims Urban Oasis (purchased in 2015 sold in 2020)
15 profitable resale transactions ranging $59-142k
High Park Residences (purchased in 2015 sold in 2020)
26 profitable resale transactions ranging $111-$255k
SUO resale transactions are actually decent, cos no losses and then decent gains I would say, since property dabbles uses leverage. Eight Riversuites is actually already 8 years old though.
