Assume you rented a house for $2,000 a month. You own the home and it is completely paid off. You also live in another house that is also paid off. Would you quit your job (most likely a higher salary and benefits) to enjoy life and never work again for some money to survive? I would assume a very frugal life.
I wouldn’t (not enough for my HCOL area). But if you are considering it, I would continue working and attempt to live on a budget of $24k/year. Save everything else you earn. See how you feel on that budget to see if it’s realistic. I have a feeling that it would be a very tight budget given that you have to maintain 2 houses.
