I have received $0 from my parents. My grandma helped me buy some furniture when I moved out to my first apartment, and bless her for that. But I cannot comprehend asking for that much money from my parents, not that they would have it to give me anyway. I feel bad when they want to pay for my dinner, let alone $30k+.
Despite that, I have managed to save more than enough saved for a down payment. But with the market the way it is I have no interest in dropping that much money for a house, especially when our landlord hasn't raised the rent for years and we have a good deal. $30k from your parents is a drop in the bucket when you're looking at a huge ass mortgage payment every month. A house would have to be magical as fuck for the amount they are gonna charge per month with the current prices and rates.
