Should i move from Western Europe to Brazil?

I’m a woman in her mid 40’s from Western Europe. Divorced, no kids. I’m living in the Canary islands, Spain. I have some questions, and it would be nice to hear some opinions from both europeans/americans living there as well as brazilians.

1. Safety

How likely is it to be assaulted/robbed inside your home? I'm not rich but my pets are loved deeply.

Specially curious about Santa Catarina : Flórianopolis, Jaragua do sul, rural SC, etc.

2. Residence permit

I’m a landlady here in the Canary islands... I'm not sure how i could get my Residence permit in Brazil.

I’m also considering opening a business in Santa Catarina... any advice about residence permits?

3. Dengue

It's not my intention to offend Brazilians ❤️ i just have an autoimmune condition (in remission now).

How likely is it to get dengue in Santa Catarina?

Specially curious about Flórianopolis, Jaragua do sul, rural SC, etc.

Notes: Language is not going to be a problem, i already understand a lot of portuguese. I’m good at languages.

Please be honest with me! 🙂

EDIT : Sure, I’m going to visit first!
