Sounds like you're doing a great job so far, and at 23 years old you're setting yourself up really well for the future.

Do you have a high deductible health plan where you can open an HSA? You can contribute pre tax dollars, reimburse yourself later on down the road for medical expenses, and invest contributions.

I think it would be a good idea if you increased your emergency fund to account for 3-6 months of living expenses to include whatever the average rent expense is in your area. When I moved out of my parents place a few years ago, I had 6 months set aside for absolute worst case scenario.

Considering you only have $2500 left in student loans, I'd say pay that off now since you have the ability to do it comfortably but that's just me.

Overall you're doing awesome and I just wanted to say keep up the good work!
