I would like to live in Chile. I'm thinking of applying for the Rentista visa for both the Temp and Perm visas. I have three questions:
1. I have an apartment at home and will get rental income (US$1200/month). But the mortgage is not yet paid off, that every month a sum of money (US$850/month) is transferred away as "Loan Payment" as shown in the bank statements. I will have tenancy agreement as proof but only 1 month of bank statement to show the rental income (because the apartment is recently rented out). What is Extranjeria looking at: Only the money coming into one's account monthly and not care about money going out? Or, do they study the bank statements to check carefully the money going in and out of the account? Has anybody with rental income also had a mortgage? I also have cash savings of US$60,000. Can I go with this option?
2. Another option (less preferred) is to borrow money from family to pay off the mortgage. So, I will have my rental income (US$1200/month). But, a sum of money will still be transferred away to my family's account to pay them back each month. The only difference from option #1 is that I can claim (showing "Title Deeds" as proof) that I own this apartment (worth US$350K), and also the money transferred away will not be shown as "Loan Payment" in the bank statements. Which option is better: Option 1 or 2?
3. Question 3 is something else: I have a PhD and years of work experience as a university teacher back home. Will sending in my degree certificates and work contracts help increase the success rate of my RENTISTA application? If so, must I also legalize my degree certs and work contracts?
What I want to do in Chile, briefly: Don't actually plan to have a job in Chile. Looking to "retire" into a simple, self-sufficient lifestyle in the campo in Chile. But I'm also open to changes... regarding e.g. finding work, if I have to to make my application stronger for perm residence. Anyway, my priority is to stay and live in Chile.
Any help will mean a lot to me. Many thanks!
