Upcoming Visit (Singapore)

Good Day,
My wife, daughter and I will be doing a whirlwind tour of Singapore in a couple of weeks (schools, estate agents etc.) and was wondering if anyone has any advice on what we might specifically investigate while we are there in advance of making the decision to relocate. I guess there are the "known knowns" but I am wondering if there are any "unknown knowns" that we can glean from this great forum.

Thanks
