You make $95k a year and you essentially want to be homeless? You can definitely find a decent studio or 1BR within a decent budget. No need to spend half your income. If you really want to save though you can find a roomate. r/DCforRent and the DMV For Rent Facebook group would probably be a good starting place. I would also join the neighborhood facebook groups where you think you might want to live as I often see requests for roomates pop up in those as well.

If you want to live in your car then more power to you, but it seems like a very extreme solution IMO. Best of luck to you.
