Financing a vehicle a few months before I expect to apply for a mortgage?
If your debt will all be less than 25% gross (yes, I see you said take home) you are in great shape. I'd get the car and not worry.  The well written mortgage is 20% down, with a housing payment (which of course includes prop tax and insurance, as noted by mhoran, below) under 28% and total debt under 36%. You are well within the limits, not even close. That's great. 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. Usually, it's not a good idea as it will not only raise your debt to income ratios,  but also impact your credit scores. However, if you have extensive credit history, having owned a home or two for a while (read: 10-20 years), taken out multiple auto loans in the past and paid them satisfactory, your credit score may not take a big hit. Possibly ust 5-10 points or it can be 30-40 points. It really depends on the depth of your credit profile.
The other answers have offered some great advice, but here is an alternative that hasn't been mentioned yet. I'm assuming that you have an adequately-sized emergency fund in savings, and that your cars are your only non-mortgage debt. Since you still have car debt, you probably don't have anything saved for buying a new car when your current cars are at the end-of-life. Consider paying off your car loans early, then begin saving for your next car. Having cash in the bank for a car is very freeing, and it changes your mindset when it comes time to purchase a car, as it is easy to waste a lot of money on something that depreciates rapidly when you aren't paying for it immediately.  This approach might be counterintuitive if your car loan interest rate is less than your mortgage rate, but you will probably need another car before you need another house, and paying cash for a car is worth doing. Lenders want to judge the stability of the stated income. Because your are new to being self-employed they are concerned about your viability. It may be possible to find another lender who will consider a shorter term of business, but it looks like the lender wants 24 months of business. You should start with your current bank/credit Union, and if they say no ask what more info you need to provide. Considering I'm putting 30% down and having my father cosign is there   any chance I would be turned down for a loan on a $100k car? According to BankRate, the average credit score needed to buy a new car is 714, but they also show average interest rates at 6.39% for new-car loans to people with credit scores in the 601-660 range. High income certainly helps offset credit score to some extent.  Not every bank/dealership does things the same way. Being self-employed you'd most likely be required to show 2 years of tax returns, and they'd use those as a basis for your income rather than whatever you have made recently. If using a co-signer, their income matters. Another key factor is debt to income ratio, if too much of someone's income is already spoken for by other debts a lender will shy away. So, yes, there's a chance, given all the information we don't know and the variability with lender policies, that you could be turned down for a car loan. How should I go about this? If you're set on pursuing the car loan, just go talk to some lenders. You'll want to shop around for a good rate anyway, so no need to speculate just go find out. Include the dealership as a potential financing option, they can have great rates. Personally, I'd get a much cheaper car. Your insurance premium on a 100k car will be quite high due to your age. You might be rightly confident in your earning potential, but nothing is guaranteed, situations can change wildly in short order. A new car is not a good investment or a value-retaining asset, so why bother going into debt for one if you don't have to? If you buy something in cash now, you could upgrade in a few years without financing if your earning prediction holds and would save quite a bit in car insurance and interest over the years between. I'd pay cash.  Car loans are amortized, so sometimes you can get upside-down on the loan between 18-30 months because you are pre-paying interest. This can get you into trouble if you get into an accident. Given the low rate and the type of car you're buying, you're probably fine either way. Used car dealers will sometimes deliberately issue high-interest-rate subprime loans to folks who have poor credit. But taking that kind of risk on a mortgage, when you aren't also taking profit out of the sale, really isn't of interest to anyone who cares about making a profit. There might be a nonprofit our there which does so, but I don't know of one. Fix your credit before trying to borrow. Hindsight is 20/20, but I offer some suggestions for how this might have gone down. If you had told the bank what was going on they might have extended the terms of your loan until the truck was ready. Alternatively you might have taken the loan (was it secured on the truck?) and put the money in a savings account until the truck showed up, while asking the dealer to pay the interest on it until the truck showed up. Or you might asked the dealer to supply you with a rental truck until yours showed up. I'm not saying I would have thought of these under the circumstances, but worth trying. There is a reason - your credit score. If you ever take out a mortgage, you might pay dearly for your behavior. The bank where you have the credit card reports the amount on the bill to the credit rating agencies. If you pay before the bill date, they will always report zero. You should wait at least till the day after the billing cycle ends, and then pay off (you don't need to have the paper bill in your hands - you can see online when the cycle closed). Depending on your other financial behavior, this will have between zero and significant effect, on the percentages you get offered for car loans, mortgages, etc. "I cannot stress this enough, so I'll just repeat it:  Don't plan your finances around your credit score.  Don't even think about your credit score at all.  Plan a budget an stick to it.  Make sure you include short and long term savings in your budget.  Pay your bills on time.  Use credit responsibly.  Do all of these things, and your credit rating will take care of itself.  Don't try to plan your finances around raising it. On the subject of 0% financing specifically, my rule of thumb is to only ever use it when I have enough money saved up to buy the thing outright, and even then only if my budget will still balance with the added cost of repaying the loan.  Other people have other rules, including not taking such loans at all, and you should develop a rule that works for you (but you should have a rule).  One rule shouldn't have is ""do whatever will optimize your credit score"" because you shouldn't plan your finances around your credit score.   All things considered, I think the most important thing in your situation is to make sure that you don't let the teaser rate tempt you into making purchases you wouldn't otherwise make.  You're not really getting free money; you're just shifting around the time frame for payment, and only within a limited window at that.  Also, be sure to read the fine print in the credit agreement; they can be filled with gotchas and pitfalls.  In particular, if you don't clear the balance by the end of the introductory rate period, you can sometimes incur interest charges retroactively to the date of purchase.  Make sure you know your terms and conditions cold. It sounds like you're just getting started, so best of luck, and remember that Rome wasn't built in a day.  Patience can be the most effective tool in your personal finance arsenal. p.s. Don't plan your finances around your credit score." The first thing that strikes me is: Is this a time-limited offer? Because if you can expect the offer to still be valid in a few weeks, why not just wait that month (which will earn you the money) and buy the car then? The second thing you need to consider is obviously the risk that in the interim, there will be an actual emergency which would require the money that you no longer have. The third thing to consider is whether you need the car now. Do you require a car to get around and your current one is breaking down, perhaps even to the point that repairing it would cost you more than buying a new car and it is currently not safe to drive? If so, compare the cost of repairing to the cost of buying; if the difference is small, and the new car would be more likely to be reliable than the old car after spending the money, then it can make sense to buy a new car and perhaps sell the old one in its current condition to someone who likes to tinker. (Even if you only recover a few hundreds of dollars, that's still money that perhaps you wouldn't otherwise have.) The fourth thing I would consider, especially given the time frame involved, is: Can you get a loan to buy the new car? Even if the interest rate is high, one month's worth of interest expense won't set you back very far, and it will keep the money in your emergency fund for if there is an actual emergency in the weeks ahead. Doing so might be a better choice than to take the money out of the emergency fund, if you have the opportunity; save the emergency fund for when that opportunity does not exist. And of course, without knowing how much you earn, take care to not end up with a car that is no more reliable than what you have now. Without knowing how much you earn and what the car you have in mind would cost, it's hard to say anything for certain, but if the car you have in mind costs less than a month's worth of net pay for you, consider whether it's likely to be reliable. Maybe you are making an absolutely stellar pay and the car will be perfectly fine; but there's that risk. Running the car by a mechanic to have it briefly checked out before buying it may be a wise move, just to make sure that you don't end up with a large car repair expense in a few months when the transmission gives up, for example. "The short answer is ""yes"", paying more towards the loan as soon as a you can will reduce the interest. There are calculators or you could work up a spreadsheet using the specialized family of functions: PMT, PPMT, IPMT. My personal view: The amount of interest you offset in this manner is going to be fairly small (I'm going to guess less than $5 or $10 a month, but I haven't done the math). I would say what is more important is to automate your payments at a comfortable level, while making sure your other obligations are taken care of. Then add an extra payment when you save up a chunk of money to pay towards it. Make sure you never miss a payment. That means making sure you set up emergency fund to cover the payments if you lose your job or need to visit a sick family member for a while or the car breaks down or ...." If you have good credit, you already know the rate -- the bank has it posted in the window. If you don't have good credit, tell the loan officer your score. Don't have them run your credit until you know that you're interested in that bank. Running an application or prequal kicks off the sales process, which gets very annoying very quickly if you are dealing with multiple banks. A few pointers: You're looking for a plain vanilla 30 year loan, so avoid mortgage brokers -- they are just another middleman who is tacking on a cost. Brokers are great when you need more exotic loans. Always, always stay away from mortgage brokers (or inspectors or especially lawyers) recommended by realtors. When I was a contractor I prioritize this way. 6 months salary nest egg while contributing to tax deferred retirement then after that you can pre pay your mortgage.  Remember you can't skip a month even if you prepay.  So once you pay that extra to your mortgage you lose that flexibility. A traditional bank is not likely to give you a loan if you have no source of income. Credit card application forms also ask for your current income level and may reject you based on not having a job. You might want to make a list of income and expenses and look closely at which expenses can be reduced or eliminated. Use 6 months of your actual bills to calculate this list. Also make a list of your assets and liabilities. A sheet that lists income/expenses and assets/liabilities is called a Financial Statement. This is the most basic tool you'll need to get your expenses under control. There are many other options for raising capital to pay for your monthly expenses: Sell off your possessions that you no longer need or can't afford Ask for short term loan help from family and friends  Advertise for short term loan help on websites such as Kijiji Start a part-time business doing something that you like and people need. Tutoring, dog-walking, photography, you make the list and pick from it. Look into unemployment insurance. Apply as soon as you are out of work. The folks at the unemployment office are willing to answer all your questions and help you get what you need. Dip into your retirement fund. To reduce your expenses, here are a few things you may not have considered: If you own your home, make an appointment with your bank to discuss renegotiation of your mortgage payments. The bank will be more interested in helping you before you start missing payments than after. Depending on how much equity you have in your home, you may be able to significantly reduce payments by extending the life of the mortgage. Your banker will be impressed if you can bring them a balance sheet that shows your assets, liabilities, income and expenses.   As above, for car payments as well. Call your phone, cable, credit card, and internet service providers and tell them you want to cancel your service. This will immediately connect you to Customer Retention. Let them know that you are having a hard time paying your bill and will either have to negotiate a lower payment or cancel the service. This tactic can significantly reduce your payments. When you have your new job, there are some things you can do to make sure this doesn't happen again: Set aside 10% of your income in a savings account. Have it automatically deducted from your income at source if you can. 75% of Americans are 4 weeks away from bankruptcy. You can avoid this by forcing yourself to save enough to manage your household finances for 3 - 6 months, a year is better. If you own your own home, take out a line of credit against it based on the available equity. Your bank can help you with that. It won't cost you anything as long as you don't use it. This is emergency money; do not use it for vacations or car repairs. There will always be little emergencies in life, this line of credit is not for that.  Pay off your credit cards and loans, most expensive rate first. Use 10% of your income to do this. When the first one is paid off, use the 10% plus the interest you are now saving to pay off the next most expensive card/loan. Create a budget you can stick to. You can find a great budget calculator here: http://www.gailvazoxlade.com/resources/interactive_budget_worksheet.html Note I have no affiliation with the above-mentioned site, and have a great respect for this woman's ability to teach people about how to handle money. Presumably you need a car to get to work, so let's start with the assumption that you need to buy something to replace the car you just lost. The biggest difficulty to overcome in buying a car is the concept of the monthly payment. Dealers will play games with all of the numbers to massage a monthly payment that the buyer can swallow, but this usually doesn't end up giving the customer the best deal. The 18 month term is not normal for a lease, typically you'll see 24 or 36 months. You are focusing on another goal of paying your student loans by then which would free up much more money for other wants (like a car) but at what cost? The big difficulty of personal finance is the mental mind game of delaying gratification for greater long-term benefit. You are focusing on paying your student loans now so that you can be free of that debt and have more flexibility for the future. Good. You're tempted to spend another $5400 (assuming no down-payment or other surprise fees) to drive a car for 18 months. That doesn't sound any wiser than $5,000 for an unreliable used car that gave you more problems than you bargained for. Presumably you got some percentage of that money back from the insurance company when the car was totaled, but even if not, the real lesson should be finding a car that you can afford up-front, but also one that you can still use when the loan is paid off (like your education--that investment will keep giving even when the loans are a distant memory). My advice would be to look for a car that has about 30k miles on it and pay for it as quickly as possible, then drive it at least for 70-120k more miles before replacing it. You may wish for a newer car, especially in 3 or 4 more years when it starts to show its age, but you'll also thank yourself when you can buy a newer better car with cash and break out of the monthly payment game that dealers try to push on you. You might even enjoy negotiating with car salesmen when you see through their manipulations and simply work for the best cash price you can get. The fluctuation of interest rates during the next year could easily dwarf the savings this attempt to improve your credit score will have; or the reverse is true. Will the loan improve your score enough to make a difference? It will not change the number of months old your oldest account is. It will increase the breadth of your accounts. Applying for the car loan will result in a short term decrease in the score because of the hard pull. The total impact will be harder to predict.  A few points either way will generally not have an impact on your rate. You will also notice the two cores in your question differ by more than 30 points. You can't control which number the lender will use. You also have to realize the number differs every day depending on when they pull it that month. The addition of a car loan, assuming you still have the loan when you buy the house, will not have a major impact on your ability to get afford the home mortgage. The bank cares about two numbers regarding monthly payments: the amount of your mortgage including principal, interest, taxes and insurance; and the amount of all other debt payments: car loan, school loans, credit cards. The PITI number should be no more than 28%-33% of your monthly income; the other payments no more than 10%.  If the auto loan payments fit in the 10% window, then the amount of money you can spend each month on the mortgage will not be impacted. If it is too large, then they will want to see a smaller amount of your income to go to PITI. If you buy the car, either by cash or by loan, after you apply for the mortgage they will be concerned because you are impacting directly numbers they are using to evaluate your financial health. I have experienced a delay because the buyer bought a car the week before closing. The biggest impact on your ability to get the loan is the greater than 20% down payment, Assuming you can still do that if you pay cash for the car.  Don't deplete your savings to get to the 50% down payment level. Keep money for closing costs, moving expenses, furnishing, plus other emergencies. Make it clear that you can easily cover the 20% level, and are willing to go higher to make the loan numbers work.
