If you have a paid for home and low expenses, you can work enough to cover expenses and save a little for old age. You don't have to "race" to "FIRE." That is something that is really common here, but not required.
You only need 25X expenses if you plan to stop working and live off withdrawals of your investments. If you plan to work to cover expenses then you don't need 25X expenses. However, if you never get to 25X expenses then you are always required to work, at least a little bit.
If you take the attitude that you are just going to work to cover your modest expenses then I would personally suggest staying in your paid off house (why are you buying a second house??). Then work for your expenses and save via the company match and other investments as noted by MDM. Save as much as possible for as long as you are going to work full time.
Know that when you "quit working" if you don't have 25X expenses then you do not have enough money. But you can stop saving, work for your expenses and let your investments grow. Read this article about "the point of retirement inevitability." That might be a good saving goal.

So, if you own your house, are working, you earn enough for all your expense, you save $1800 per month and you have tens of thousands of dollars invested then you ARE very financially secure. Congratulations.
