WCI Podcast #219 - Financial Priorities as a New Attending

I'm two years out of training and working as an IM Hospitalist. Going for PSLF. Saved $112,000.00 in the last two years that I'm still trying to figure out where to invest. My hospital offers 18% (of my annual income) retirement fund (unmatched, I contribute $0) into a 401a account. I also maxed out the $19,500.00 contribution to my 457b account. No credit card debt. Car loan for 2020 Luxury SUV that is 0% interest for 5 years ($48,000 balance). My monthly expenses are only about $4500.00 per month. Any tips?
