Small update:
Windfall came and went. The check was in my hands for 11 minutes before it was deposited in the bank. lol
I did make a few adjustments due to opportunities that appeared recently.
All debt has been paid off! My unbury.me account is closed!
Car insurance dropped by half as I switched to PLPD coverage. That saves about 60 a month, but I paid the 6 months in full and saved even more.
For the emergency fund, I decided against creating an account at a separate bank for a sub-inflation savings account. I instead threw my emergency $4000 into VTI in my taxable brokerage.
I figure if I need that emergency money immediately, I have over $15,000 worth of credit spread through normal credit cards and store credit cards, some of which are 0% interest for 6 months to 18 months from purchase. I would then have a lot of time to sell shares to pay off that credit.
I also used this opportunity to start mild credit card churning. I signed up for a BoA Cash Rewards card for the delicious $200 sign up bonus. I use this card for everything including my bills, and set it to auto pay off every month. In a couple months after my bonus comes through, I will look around at the latest deals to see if anything else compares and had a nice bonus. I will stay under the 5/24 rule.
The other opportunity I came across was a different boat. I know it's not that Mustachian, but boats are life in my family. This time of year all the great deals pop up as people don't want to pay to winterize and store their boats, so they offload them cheap. I found a boat that maintains everything I love about my current boat, but provides more protection from wind and waves, and holds 7 people comfortably. It's in rough shape but after a good pressure washing and a few replacement parts, she is a badass vessel. I haggled the price down and paid cash of course!
Thankfully I can store both boats for free and do my own maintenance so costs are in control.
I have listed my old boat on Craigslist but don't expect any bites until spring. I will offload it then and we will have double the boat for only a couple thousand dollars of investment (I paid less than half of what similar boats are listed for).
My 401k enrollment allows changes starting October 1st. I have already set my contributions to 97% of my gross paycheck, leaving just enough for my healthcare, vision, and dental costs.
Starting January of 2020, I will adjust those contributions to max my tIRA by April, or in 7 paychecks. I currently have about $12,000 left to live off of until next spring, and I am feeling significantly less stressed about money and my future.
Thanks for all the advice everyone.
