Never take money from your 401k. You didn’t even mention that you’ll have to pay a penalty/taxes to withdraw from your 401k so you’ll be taking out far more than you’ll be using.

Also, stop thinking of rent as throwing away money. It’s money that buys you housing. You can be much more flexible renting too. Move to a different neighborhood. Move to a smaller place to save money. Buying a house can be a hindrance in many circumstances and can come with many additional expenses. Just go to a home improvement store on the weekend and watch all the happy homeowners throwing away money on plants, mulch, ceiling fans, French doors, new knobs for the cabinets.
