I'm 23 and put 20% down on my house last summer with zero money from my parents. Sure it's not in NY/LA or some major market, but it can be done. Just need the patience and diligence to save if owning a home is something important to you.
Like I said, I really respect what you were able to do in acquiring your home and I think FHA and assistance programs can be good, but I would not advocate for putting less than 15% down unless you really really know what you're doing. VA loans may have been great in the 60s and 70s when the housing market wasn't inflated like it is today. At that time you could bank on home equity appreciation so the risk of having no money down was lesser. Like

mentioned though, it's a different market now. You can't bank on homes appreciating like the baby boomers once could.
