Greenery is not for everyone ! There are loads of reasons for not moving back to UK, the Brexit fiasco being one!
Anyway one more idea for the "where to live" question
There's a firm called Cityloft, which has a good "package".
They rent out low end apartments, mainly on HK Island
And you can book a place in Sheung Wan, Causeway Bay, Wanchai etc just for one month
The deposit is very small.
The rooms are fully self contained (bed sheets provided, and changed weekly)
ALL utilities are included in the rent.
Prices start at $8000/month.
If you booked a room for a month you could explore HK at weekends and decide where you want to rent in the long term.
Final thought, a drinking buddy is between contracts and has a room in a 4 star hotel for $250 a night
With the current protests, which aren't going to end any time soon, Hotels are hurting and there are some great deals !
