Sorry for the book...
I'll only speak for myself, but to me the idea of good debt is debt I use to buy assets (mortgages on rentals, some student loans, etc.). I consider bad debt to be debt for liabilities (cars, credit cards, etc.) From there, I go with high and low interest debt. High would be like credit cards (22% or whatever) and low would be mortgages (3-4% these days). So, for me, debt gets graded on two things. If I borrow money at 12% to buy a rental, I consider it high, good debt. If I borrow to buy a car at 2%, I consider it low, bad debt.
Anyway, I try to avoid bad debt completely and only take on good debt if I can help it. Once I have debt, I don't really care if it's good or bad. I mean, I owe it and I just want to pay it off in the best manner possible. Everyone has their own comfort level, but I feel like it's reasonable to invest money and expect a 15-20% return (by the time you factor in appreciation, cashflow, tax benefits, loan retirement, etc.).
If I had debt in the 15%+ range, I'd make it a priority to pay it off as quickly as I could. It's easier than investing and helps my financial picture at roughly the same percentage. I'd probably keep debt under 5% as long as I can. Honestly, I'll borrow as much money as the bank will let me at 3-5% because I feel like I can invest it at 15-20% and create a cash machine. Between 5-10%, I'm probably paying it off, but not going crazy to do so. That's my personal comfort level. Everyone's is different.
To be specific to what you mentioned, I would pay the minimums on the student loans if they were 5% or lower. I just think you can utilize those dollars more effectively by investing. The idea of renting your house means that you would have bought a new, better house to live in. My wife loved the idea. haha. We hated packing up and moving, but we rent out our old house and live in a better one now. I know this is a real estate website, but stocks should be able to give you an easy average of 10% or so. Some years a lot higher and some years a lot lower, but 10% is a reasonable hope to get. I'm not sure what you're invested in, but I'd personally use that as a bellweather. If I had debt above 10% or could invest at something above 10% I'd skip funding my IRA. If I had debt below 10% or could invest at something below 10% I might keep funding my IRA.
Again, these are my personal preferences. Some are more aggressive and some are less. You have to do what allows you to sleep at night. Also, it goes without mentioning that these are unprecedented times (at least for anyone currently alive), so I'd consider that in my thinking as well. If you believe that the world will fall apart financially soon, you probably just want to wait on the sidelines. If you're comfortable with where we're at, you should be good to go.
Sorry again for the book, but please feel free to reach out with any questions or clarifications I can offer. Best wishes.
Also, this "advice" is probably worth what you paid for it. I definitely don't pretend to know all... or much. haha
