You could start for instance by familiarising yourself first by reading various guidances and you might want to ask a more specific question.
Indonesia is very big so you will need to determine where you want to live first. But it seems you have decided to live in Bali. So the next step is to determine whether you want to live with a western lifestyle, atmosphere. If it is, than Cangu, Seminyak areas are the places to live which might be meeting your expectation. There are a lot of vloggers from foreigners living in these areas if you search it on youtube (YT). This will give you an impression about he day to day living in these areas. Whether you want to live there with similar lifestyle, with western budget or not.
Alternatively, if you are looking for a more affordable places to live in Bali, than stay away from places where there are a lot of NOMADS, exclusive tourist spots areas with posh apartments/accommodations, targeted for tourists. There are few places like this such as areas around Denpasar, Sanur, Ubud, Lovina.
