I work at CKS airport and started a thread recently about where to live in Taipei with easy access to the airport. forumosa.com/taiwan/viewtopic.php?t=47290
Currently, we live in Nankan, which is ideal for commuting to CKS daily, but not so good for social life in Taipei. To be honest, commuting between Taipei and CKS take 1-1.5 hrs each way…but heading into Taipei from Nankan to go out typically takes 30mins, because generally that’s not during rush hour.
We are in the process of looking for a place in Taipei that is close to the freeway, but even so the thought of 1hr+ each way everyday commute does not impress me. If your husband works a normal 8-5 job at CKS and lives in Taipei, it will mean he will be gone around 6.45am and back home about 6.30pm - which makes for a big day. In somewhere like Nankan, it would be 7.45am and home by 5.15pm.
Nankan is up-and-coming with many new apartment complexes (like about 20+) all nearing completion. I expect there will be some great rental deals coming along, so it really depends if you want quality of life at HOME or quality of life out and about in Taipei. IF you go out for a dinner once or twice a week only, then living closer to the airport and driving into Taipei afterhours might suit. IF you plan on spending a lot of time out in Taipei, then letting your husband do the commuting might work better.
I am not a parent, so this is an unqualified opinion, but if it was me I would put our 4 year old into a school out here. I’ve seen friend’s western kids around that age pick up mandarin so fast it really is an opportunity for you to think about. By the time he is around 6, you could look at more formal education and by then you will know more about what you want from Taiwan.
Anyway, please PM me if you want anymore specific information. There might even be a good chance I will see your husband out at CKS from time to time.
hope that helps,
