I love how people say 'buy a few properties' like it's nothing. Either your parents are rich and you're well taken care of, hence not knowing the value of a dollar, or you just have no idea what you're talking about..
You do realize that even if you did want to do what you said, no bank is going to give you a 100% loan for 1 house, so that you can use your savings for the 'few properties' you plan to buy with your savings, which you'd want to be in excess of $2-300k...
