How long to wait before refinancing a high interest car loan, after improving credit history?
Between half a year and a year should be enough to improve your interest rates drastically on car loan refinance. Make sure that your new credit card has already been reported to the agencies, and that the credit/debt ratio is lower than 30% on your revolving (credit card) accounts. That also means that you shouldn't carry too much balance, even if the APR is 0%.
Is it really worth the interest you'd pay over a year for a relatively minor and temporary bump to your credit score? I mean, you just bought a car so I'm assuming you probably aren't looking for another loan in the near future. "My husband made a similar car loan decision when he was younger and didn't have an established credit history / favourable credit rating.  As a result, he ended up paying triple what the car was worth, because of the interest. When we consolidated our finances, this ugly loan was first on our list of priorities to change, convert, eliminate, but unfortunately, in our case, the terms of the loan were such that only the lender benefited.  There was no incentive to pay off the loan early, in fact, we would have to have paid all the future interest at once, without saving a penny. So check the terms of your loan - hopefully you're better off than we were.  In our case, the only upside we could figure was the lesson of ""live and learn""!" I have heard that it is better for your credit score to pay them down over time. Will it make much of a difference? I have never heard that, however, the financial institutions (who are charging you an amount of interest which was at one time in the not so distant past classified and punishable in state criminal codes) really enjoy you thinking that way. You are clearly capable of doing the math yourself. While I don't know the exact numbers, I am totally confident that you will find in about 5 or 10 minutes (if that long) that eliminating debt of any kind in your life will pay an immediate return that beats the great majority of other investments in terms of risk/reward. After the immediate financial return, there is a quieter, subtler, and even greater long term benefit. Basic principle: Highest Rates First Perhaps this decision could be considered slightly less important than deciding not to smoke during your youth; but I would put it as a close second. You are already in a position where you can see the damage that your prior decisions (about financial debt) have produced. Run the clock back to the time in your life when you were debt free. Now, pay off that debt with the big check, and start from zero. Now, turn on your psychic powers and predict the same amount of time, in the future, with the same amount of money (don't even try to adjust for inflation; just use flat dollars) WITHOUT losing the money which you have given to the financial institutions during this previous part of your life. Do you now see why the financial institutions want you to think about slowly paying them off instead of waking up tomorrow without owing them anything ? Paying weekly to be able to have maneuver room under your credit limit is a way to handle low credit limits. Doing it to boost your credit score when you have no immediate need for a loan is wasting energy.  A few months in advance of buying a car or house, you can start to worry about your utilization rate. When you apply for the loan they will pull your credit file, and that will lock in your utilization rates. Then make sure that you pay the balance quickly, and if you need to make a big purchase pay the bill before the account closes for the month. Keep in mind that if you pay the balance every month the highest utilization rate will occur the day the payment is due. This is because it not only has all the purchases from the previous bill, but all the purchases you have made since that bill closed. For example if you have a credit limit of 10K and you spend 2K a month on the credit card, on the day the payment is due it is not unusual to see the total owed to be above 3K. If they pulled your file on that day, your utilization rate would appear to be above 30%. You can negotiate a no penalty for early payment loan with dealerships sometimes. Dealerships will often give you a better price on the car when you finance through them vs paying cash, so you negotiate in a 48 month finance, after you've settled on the price THEN you negotiate the no penalty for early payment point. They'll be less likely to try to raise the price after you've already come to an agreement.  My dad has SAID he does this when buying cars, but that could just be hearsay and bravado. Has said he will negotiate on the basis of a long term lease, nail down a price then throw that clause in, then pay the car off in the first payment.  Disclaimer: it's...um not a great way to do business though if you plan to purchase a new car every 2-3 years from the same dealer. Do it once and you'll have a note in their CRM not to either a) offer price reductions for financing or b) offer no penalty early payment financing. As for refinancing: Many institutions charge up-front fees when doing any type of vehicle loan. Typically this is in the neighborhood of 1% the value of the loan, with a floor of $100 (although this may vary by lender). However, for the loan the be secured by the vehicle, the principle value must be less than the collateral value. In your case, this means there is a collateral shortfall of $4,000. When working with a traditional bank, you would have two options: pay the difference up front (reducing the principle value of the loan), or obtaining a separate loan for the difference. This separate loan would often have a higher interest rate unless you have some other form of collateral to secure it with. I doubt CarMax would do a separate loan. All that being said, if you plan on selling the vehicle within the next twelves months, don't bother refinancing. It won't be worth the hassle. If it's possible in your case to get such a loan, then sure, providing the loan fees aren't in excess of the interest rate difference.  Auto loans don't have the fees mortgages do, but check the specific loan you're looking at - it may have some fees, and they'd need to be lower than the interest rate savings. Car loans can be tricky to refinance, because of the value of a used car being less than that of a new car.  How much better your credit is likely determines how hard this would be to get.  Also, how much down payment you put down.  Cars devalue 20% or so instantly (a used car with 5 miles on it tends to be worth around 80% of a new car's cost), so if you put less than 20% down, you may be underwater - meaning the principal left on the loan exceeds the value of the car (and so you wouldn't be getting a fully secured loan at that point). However, if your loan amount isn't too high relative to the value of the car, it should be possible.  Check out various lenders in advance; also check out non-lender sites for advice.  Edmunds.com has some of this laid out, for example (though they're an industry-based site so they're not truly unbiased). I'd also recommend using this to help you pay off the loan faster.  If you do refinance to a lower rate, consider taking the savings and sending it to the lender - i.e., keeping your payment the same, just lowering the interest charge.  That way you pay it off faster. "Pay it off. If necessary, get a loan so you can pay it off; that's what refinancing is all about and your favorite bank or credit union would be happy to help you with this. If that isn't sufficient to make the car affordable you may need to sell it, take the loss, and learn from the experience. Sorry, but you made an agreement and it's up to you to find a way to meet your end of the bargain. (If you had decided you didn't like this loan within a few days of signing, you might have been able to back out under ""cooling off period"" laws. But those only allow a very limited time for reconsideration.)" Imagine that your normal mode of using credit gets you a score of X. As time goes by your score trends upward if the positive items (length of credit) outweigh your negative items. But there are no big increases or decrease in your score. Then you make a one time change to how you use credit. If this is a event that helps your score, there will be a increase in your score. If it is bad thing your score will drop. But if you go back to your standard method of operating your score will drift back to the previous range. Getting a car loan for a few months to get a bump in your credit score, will not sustain your score at the new level indefinitely. Overtime the impact will lessen, and the score will return your your normal range. Spending money on the loan just to buy a temporary higher credit score is throwing away money. "With that credit rating you should have no trouble getting a rate in that range. I have a similar credit score and my credit union gave me a car loan at 1.59%. No haggling required. In regards to your question, I think you have it backwards. They are more likely to give you a good rate on a high balance than a low one. Think about it from the bank's perspective... ""If I give you a small sale, will you give me a discount?"" This is the question you are asking. Their profit is a factor of how much you borrow and the interest rate. Low rate=less profit, low financing amount = less profit.  The deal you proposed is a lose-lose for them." Buy a modest vehicle with a manageable payment.  Keep the payment low enough ($200-300/month) to keep your DTI (Debt-To-Income) ratio clear.  The short-term ding to your credit for new credit should disappear in 3-6 months (your time horizon).  Having a mix of credit is part of the credit scoring model, so having an installment loan is not a bad thing.  Relax. I am going to give advice that is slightly differently based on my own experiences. First, regarding the financing, I have found that the dealers do in fact have access to the best interest rates, but only after negotiating with a better financing offer from a bank. When I bought my current car, the dealer was offering somewhere around 3.3%, which I knew was way above the current industry standard and I knew I had good credit.  So, like I did with my previous car and my wife's car, I went to local and national banks, came back with deals around 2.5 or 2.6%.  When I told the dealer, they were able to offer 2.19%. So it's ok to go with the dealer's financing, just never take them at face value.  Whatever they offer you and no matter how much they insist it's the best deal, never believe it!  They can do better! With my first car, I had little credit history, similar to your situation, and interest rates were much higher then, like 6 - 8%.  The dealer offered me 10%.  I almost walked out the door laughing.  I went to my own bank and they offered me 8%, which was still high, but better than 10%.  Suddenly, the dealer could do 7.5% with a 0.25% discount if I auto-pay through my checking account. Down-payment wise, there is nothing wrong with a 35% down payment.  When I purchased my current car, I put 50% down.  All else being equal, the more cash down, the better off you'll be.  The only issue is to weigh that down payment and interest rate against the cost of other debts you may have.  If you have a 7% student loan and the car loan is only 3%, you're better off paying the minimum on the car and using your cash to pay down your student loan.  Unless your student loan balance is significantly more than the 8k you need to finance (like a 20k or 30k loan). Also remember that a car is a depreciating asset.  I pay off cars as fast as I can.  They are terrible debt to have.  A home can rise in value, offsetting a mortgage.  Your education keeps you employed and employable and will certainly not make you dumber, so that is a win.  But a car?  You pay $15k for a car that will be worth $14k the next day and $10k a year from now.  It's easy to get underwater with a car loan if the down payment is small, interest rate high, and the car loses value quickly. To make sure I answer your questions: Do you guys think it's a good idea to put that much down on the car? If you can afford it and it will not interfere with repayment of much higher interest debts, then yes.  A car loan is a major liability, so if you can minimize the debt, you'll be better off. What interest rate is reasonable based on my credit score? I am not a banker, loan officer, or dealer, so I cannot answer this with much credibility.  But given today's market, 2.5 - 4% seems reasonable. Do you think I'll get approved? Probably, but only one way to find out! "Assuming I don't need any other new lines of credit, can I get pre-qualified repeatedly (and with different banks) with impunity? Yes, but only for a limited period. FICO says: Hard inquiries are inquiries where a potential lender is reviewing your credit because you've applied for credit with them. These include credit checks when you've applied for an auto loan, mortgage or credit card. Each of these types of credit checks count as a single inquiry. One exception occurs when you are ""rate shopping"". That's a smart thing to do, and your FICO score considers all inquiries within a 45 period for a mortgage, an auto loan or a student loan as a single inquiry. However for your situation, since you won't be getting a loan for several months, getting inquiries more than 45 days apart will each count as a separate inquiry." Does the full time PHD student extend to 70-80 hours/week or more? If not, can you pick up an extra job to aid with living expenses? Also, whose name is the debt in? Is your wife paying to avoid the black mark on her credit record or her mother's? Basically what it looks like to me is that you guys currently have a car you cannot afford and that her mother doesn't seem to be able to afford either, at a ridiculous interest rate on top. Refinancing might be an option but at a payoff amount of 12k you're upside down even when it comes to the KBB retail value. I'm somewhat allergic to financing a deprecating asset (especially at a quick back of the envelope calculation suggests that she's already paid them around $18k if you are indeed three years into the loan). What I would be tempted to do in your situation is to attempt to negotiate a lower payoff to see if they're willing to settle for less and give you clean title to the car - worst thing they can say is no, but you might be able to get the car for a little less than the $12k, then preferably use your emergency money to pay off the car and put it up for sale. Use some of the money to buy her a cheaper car for, say, $4k-$5k (or less if you're mechanically inclined) and put the rest back into your emergency fund. The problem I see with refinancing it would be that it looks like you're underwater from a balance vs retail value perspective so you might have a problem finding someone to refinance it with you throwing some of your emergency money at it in the first place. Just call your credit union and ask if they will let you refinance at the lower rate. If they won't, then just increase your payment every month so that your car is paid off early (in 36 months instead of 60). You won't get the lower rate, but since your loan will be paid early, you'll be saving interest anyway.
