I was talking about renting eh. Yeah living with your parents it's quite convenient, specially if you can save a good amount to be in a good position when you do move out without having to worry of not knowing if you'll make it till the end of the month or not.
Yeah ideally you'd get a mortgage, in that case the minimum down payment is 5% of the value of the property, average is around 17%. Here mortgages practically didn't exist till this year since a long time ago, you could only get credits and they were impossible to get for about 70% of the population and they had silly interest rates. So most people who bought a house either saved most of the money and then got an small credit to cover the rest, or they rented which is/was not easy to get in downtown Buenos Aires neither as you needed a house in the same town to use it as a guarantee apart from 4 months in advance (current month, one month deposit and two months as payment for the real-state company) it was almost impossible to achieve for most people. Luckily things are getting better in that aspect recently as the government has made credits of to about £100k payable in 30 years available to people earning upwards two minimum wages. That's not impossible to get, but you do need to either be on a registered job, but that's kinda difficult when 35% of the working population does so in unregistered jobs, and that's precisely the majority of people who don't own a house.
