First time home buyer looking for advice

[Account Closed]

Hi,

I'm a pretty young individual. I'm looking to buy a single family house with a purchase price around 400-500k. My question is how much do I need to save to be able to legally buy this house? My parents are able to help me with the mortgage/down payments so that's why financial security isn't a big issue. I just need to know how much I need to "get by". What loans would i qualify for? I heard there are some very good first time home buyer programs? This is new york by the way.Thank you!
