Which is fine, but it's sad how it's just assumed a site on a .com is for america only. Of course a monoculture of 350 million customers is more than pretty much any other country which explains why SV produces so many successes.
Defaults are crazy too - $2,750 for home insurance?!
HOA: I can translate it to the monthly payment in my building to pay for the cleaning, electricity for the lift, and other stuff.
House vs Apartment: I think it's confusing. It's correct for the personal case of the OP, but it's confusing for everyone else.
Mortgage interest <= 10%: In pesos? :) Most mortgages here are now in a fake money "UVA" that somewhat tracks the inflation. So if the interest is 5% in UVAs and the annual inflation is 40%, the actual interest is 45% (approximately, read the fine print before signing).
It would be nice to auto update the graph every time something changes.
It's nice that it has tips. Hi from Argentina! We have a somewhat different customs here so some fields are hard to guess. For example, I don't know if I can fill my taxes jointly.
Another detail that confused me is that I didn't expect to sell the home after 14 years. It's not usual here, but I guess it changes in each country.
Protip: Add a field that says "My S.O. want's to move anyway" :)
