<prompt> Human: This is my first post here, Ive read through the start here guide and it made me extremely anxious about my current finances. I am a recovering addict, so my credit is trashed and for the past 20 months Ive been trying to rebuild my life, including my finances.I have a decent job at a bank, making 35k yearly. I am taking full advantage of their 401k match. I have a credit card with high interest but I only use it for Spotify and Prime and then immediately pay it off so the balance pretty much stays at 0. I pay the minimum on my student loan payments I owe 6k. I had about 250 on Robinhood in ETFs and stocks but I just sold all of them and will be putting the cash into an Ally savings account to start up my emegrency fund. My biggest stressor right now is my car loan. Alittle over a year ago I financed a 2013 Nissan Altima at 23 interest through Credit Acceptance. 315 a month for 60 months. I currently have about 48 months left to go. I got approved by Capital One for 12.46 for 36 months. I also got approved by a local credit union got 9.75 for 36 months. The credit union will require me to set up a checking account with them in which my paycheck gets directly deposited in order to auto pay the loan payments. They also require I keep an active savings account it only accrues .05 interest if I read their website correctly. I had a second local credit union deny me after reviewing my credit history. So Ive have three hard inquiries on my credit this week.Ive read people talk about putting a down payment when refinancing an auto loan - I expect to get around 1000 tax refund next year... Should I wait until the refund and use it as a down payment, or should I jump on the offer to cut my interest rate in half?Tried to provide all the relevant info... If theres anything else lemme know Ill provide the honest details!  <response>: That credit union deal you mention is too good to be true. Jump on that immediately if its still a available. Theres no benefit to waiting. You need to pay back the loan, no matter what. Even if you loose the car to a repo or a wreck, you still have to pay back that terrible loan in full. If you can refinance now, then do it. Used cars just dont finance well. They always depreciate quickly while the loan charges interest, causing you to be upside down on the loan. Theres nothing you can do about that except two things, pay the loan faster, so you get charged less interest, and drive less, so the car depreciates more slowly and you spend less on maintenance and gas.
