Hey @Ryan Holyn!
Congratulations on deciding to pursue FI and welcome to BiggerPockets! I'm also from the Naperville Bubble :)
First I'd like to say that I think you've already started in the right direction and you're in a great position. You have no expenses related to rent, a car payment, utilities, etc and your biggest expenses right now are your student loans. I'd look to pay those off as soon as possible as it'll free up a lot of your cashflow to invest in other things.
I'll bring up a point I haven't seen others mention yet as it hits close to home. I'm a very spontaneous person and budgeting/planning/looking at the big picture do not come to me naturally. Since you've mentioned that you're not great at budgeting, I'm going to make an assumption about you that you're similar to me in that regard. When I first started my FI journey, I didn't have a FI plan/clarity on my timeline. When do you want to achieve FI? What timeline are you giving yourself, and is it a realistic timeline? A 5 year timeline puts a lot of pressure on you to make the "right choices" and maximize/optimize everything. Having a clearly defined "target" may make it easier for you to prioritize where to put your money. Allowing yourself enough time to achieve FI may relieve some of the pressure you feel. My priorities for retiring in 15 years vs at 59 would be vastly different.
If you plan to hit FI sooner, then I think your retirement accounts fall to the bottom of the priority list and that you should focus more on assets that can produce cashflow now/pay off debts to increase your cashflow. A house-hack is a great way to start your real estate investing journey and I highly recommend it, and I think @Ty Ash gives a great example as to how you may be selling yourself short on how much of a mortgage you can afford.
With regards to budgeting in general, I've personally found a less specific/strict budgeting plan to work best for me. I allocate a percentage of my monthly income to my living expenses/fun budget, and focus more on staying under that percentage every month, rather than going down to the nitty gritty individual expense...I've found that to be less restrictive which works better for my brain. And it personally took me a long time to build the HABIT of budgeting...it takes work and effort before it becomes habitual. I hope this helps a bit!
