I think you'll be so happy a year from now that you made the changes you've recently made & got started on this journey. How is your tracking of expenses going?
It seems you didn't love YNAB, but I thought I'd share how much I DO love it in case you would consider trying it again. I've gone back & forth with tracking expenses, and with cash-flowing two kids in college, it's essential for my peace of mind. What I love about it lately (I'm sure other programs could do the same thing, actually) is allocating dollars to categories as they come in and then nearing as the next paycheck arrives, I start to move unspent money to categories I've begun to call "Priorities for Extra Money." We're sorely in need of a new mattress & are swapping bed sizes AND I am super interested in adjustable beds (king split!) - which is fairly pricey (on Amazon for about $1400). ANYWAY, since I've already taken care of my savings for the month (that happens automatically), extra money actually gets to be used for non-essential purchases, even luxuries.
In your case, I'd create a couple of "Priorities for Extra Money" categories. 1. "Send $50 extra to student loan" and 2. Licensure expenses. If you start with $1000/month in your grocery category and $200 in gas, just moving a few dollars here & there throughout the month & then everything left over as the month ends, you will start making real progress on things.
In addition, make sure you create categories for things that are easy to ignore but can bite you in the butt. For me, that's home maintenance & repairs. I really let that go & am finding myself with a lot of deferred maintenance. Setting aside money monthly for future unknown repairs is useful, plus when they come up you're more likely not to postpone them because you have money allocated already. Similarly, once you get your emergency fund solid, create categories for "car insurance deductible" and "Max out-of-pocket deductible," etc.
A few other things:
1. Do you have an Instant Pot? (That would have been a good Prime Day purchase if not!) It's pretty fantastic for making large quantities of things like rice, beans, meat. Having rice & beans available all week can provide a good base from which to build.
2. It looks like you're moving forward with solid cuts to your expenses, which is great. I do think it's important you get your license to practice in Washington, and in the meantime find a way to earn at least a few extra bucks, be it from babysitting occasionally, driving for Lyft, or really anything. Your family needs some resiliency.
3. I think it's great you don't use credit cards & I suggest you keep it that way for the foreseeable future. It wouldn't hurt to have one in reserve.
4. I also think it's great that you're planning to have your kids go the economically-smart route for higher education. College can be a huge expense & you guys need that money for your own retirement so you're not a financial burden on your kids down the road.
5. Please make sure that your husband has a lot of life insurance (this is part of resiliency, too). It would be hard for you to replicate his income, and the time to get life insurance is when you're young & healthy for the best rates. Term insurance that takes him 20-25 years out is the best for you. I imagine he has some at work, but it likely won't be sufficient. Research companies by looking for high ratings from A.M. Best.
6. I know some of the suggestions we're all making might seem insane to you now, but re-read them months down the road & I bet some of the ones that seem un-doable now will appear reasonable later. That's kind of how it works.
Best of luck!
