Neither do all of my friends. All that's required is having parents that want to help you get a house.

For instance my girlfriend makes twice the money her parents ever did. She still couldn't have afforded the full down payment on her house without a 4% loan from her mother as they were entering retirement. This arrangement ends up being beneficial to all parties.

I wonder how common even that much help is. That would be completely unthinkable to anyone in my circle. I personally send about $400 per month on average to help my mother make ends meet. I'm certainly not going to be getting a several thousand dollar loan from anyone in my family.

For reference, this is in southern New Jersey and I'm on the older end of the millennials.
