Thinking about retiring early here, questions

I initially wrote this post about Panama but in doing my research I realized that the world is big and I might be casting my net a little small. There is a lot of conflicting information on the Net, this site seems to have quality people and info.

I'm a Singaporean national who doesn't like his country of origin and is looking for a fresh start somewhere else. I'm also openly bisexual and polyamorous, in my early 40s.

I can prove about 1k+ income a month from private investment income.

a) What are the real costs of living there? I'm single and just need a basic room. Don't care about location as long as basic needs are met, but fast internet is a necessity as I WFH.

I cook for myself and don't eat out much, so I can keep that down. I also am not big on entertainment and don't watch movies.

I do need some place to exercise, preferably a park or similar.

What is healthcare like?

b) What are the visas like? Are retirement visas easy to obtain?

c) What is the LGBT situation like? While I'm not militant about my orientation, it is who I am. In my experience there is always some queer community in all countries, even the conservative ones.

d) I'm assuming the infrastructure is relatively decent? When I moved to the USA I had to get used to where the barbers where, dentists etc.

e) Is the bureaucracy as horrible as they say? In my experience it's been bad everywhere. (I've lived in many countries)

I'd appreciate any help, as well as anything I haven't considered.
