I'm a newbie as well, both on this forum and in Singapore. I have been here for 1 month now and did a lot of online research prior to coming, but obviously, seeing the neighborhoods and actual units in person is a totally different thing.
First, if your company or husband's co is providing you with temp housing at a Service Apartment
, you can use that time to do a lot of visits. If not, I would recommend even paying for the short term premium stay at a service apartment so you can have the time to do a proper search. Like you, I was very averse to high rise living...apparently, this is common with Americans according to my (local) broker. Whereas the locals prefer high floors, foreigners in general like to be low to the ground so you are not alone.
We ended up finding the perfect apartment, but no units were available on low floors...anyway, we asked our agent to just continue searching and we lucked out with a ground floor not too long ago so we are negotiating terms. The best thing is to be specific with what your needs are and then communicate that to your agent. In my opinion, all of the units appeared to be relatively child-safe - though I do not have children so I didn't look for that criteria. The windows for the high floors open a crack, but there is a latch or mechanism to fully open it to have air flow if you want. For 7k/mo, you're probably looking into a newer building so you may be surprised on the level of safety measures built in.
