I hear you, I bought a flat in the Tokyo suburbs for the "massive" 300 square foot garden off the patio on the ground floor- great for letting cats out as well as planting a Japanese-style garden that I was sad to part with when I moved to HK. Although I had a giant rooftop 500 square foot balcony with views to die for on Peng Chau, I was afraid to start a massive garden due to the incredible watering commitment (very sunny and windy, dries potted plants out fast, what to do when traveling, etc.). Feel guilty that I never really used the space to its potential, especially when viewing some awesome gardens from neighbors.
It's a lot to uproot yourself if you are not sure of an improvement in life- I regret my move back to the US as I was pretty happy in my former job in HK, but for some reason felt I should move back to the US and put in more time on my social security in order to receive a larger monthly check when I retire and also to be nearer to family. Well, most of the family couldn't give two hoots about where I lived only my mother...so I wasted 5 years back in the states and two of those were about the most miserable of my life (long story).
Therefore I am the first person to say that if you are relatively happy, then don't risk a good thing. My move to TW involves the same job, same people so low risk. But sad that the original plan was to more or less split time between TW and HK and, in coronavirus reality, this is not actually possible for the foreseeable future. Hoping that some coworkers will keep the Peng Chau flat, I am still paying while my cats serve their 6 month waiting period to come to TW. After that, not sure if the current coworker will want to share it with friends and split the rent, or will move back home to save money. It's such a fabulous and unique place, I have spent a total of 4 years on Peng Chau and will never find something I like as much unless I win the lottery and buy something with a similarly fabulous view in Hawaii.
