Purchases of homes are either done in cash (more rare) where the buyer owns the home entirely at the time of purchase, or they get a loan from a bank (a mortgage) usually spanning 15 or 30 years. If they are borrowing from a bank, then they must pay a portion of the loan and interest back monthly. This is the mortgage payment. At the end of the 15 or 30 years, the buyer owns the home entirely themselves and does not have to make a monthly payment on their home. I’m simplifying this a bit and ignoring that homeowners need to pay monthly insurance and taxes on their homes usually.
Those that either cannot afford to buy their home (or choose not to for other reasons) pay a monthly rent to the owner of the property (landlord).
Is this the same way people pay for their housing in Argentina, or does it work differently?
