I have read the posts on forum. We are moving from US to Singapore in June. Afterall, everyone needs to do smthg diff at one point in life

We are planning to live in East Coast. My DH will be working in Changi Business Park. I really like Costa del Sol but looks too expensive. Bayshore is better in terms of affordability. I looked at Mandarin Garden also, the attractive feature is underpass to East Coast park and a Kindergarten school within the complex.
Our kids are 5 and 3. NPS is a choice right now but considering other Kindergarten options also.
I'm contemplating to put my older one to local school next year, lets see..
Pls comment on condo and school, two most imp decisions.
Also, what is a good service appt? Is there anyone in East Coast. I cudnt find any. If not, then on Orchard Rd will do.
