How to get a loan for expensive NYC Apartment to "House Hack" ?

[Angelica Rose]

I'm curious about this. As someone pointed out, the req. here is often that you make 80x more than the monthly payments would be. I only make 50k before taxes and I'm single.  I would like to "house hack," and rent rooms in a decently popular area, while living in the space myself. I would need a massive loan. How to get this? 

Also what kind of strategy is best for this scenario? I was thinking I should aim to have a few months to a year in mortgage payments saved up to account for time finding tenants and then time to sell the property if it doesnt work out. 

This would be a few years from now, as I need to save more, but I'm very interested.
