Confused why you don't think this is a problem?? just because family will be there for you when no one else will doesn't mean they are financial liquid enough to support you with $50,000-$100,000 in cash. Clearly that is your situation but for the VAST majority of Americans that is not the case.
Average home price in America is over $400,000 which means a 20% down payment is $80,000.
