How to approach building credit without a credit card
Ways to build credit without applying for credit cards: It takes some time for these types of actions to positively affect you.  I'd say at the very least 6 months.  You won't get the full benefit for several years.  However, the earlier you get started, the better. Apply for a secured credit card (several financial institutions provide these, including most banks. WalletHub gives you a way to search/filter for these cards quite easily).  You will need to deposit funds to cover your credit limit.  Deposit as much as they allow, I believe it is 500.00.  Pay for EVERYTHING with the card.  Monitor your balance due and keep paying it off, to bring the balance due down so you can continue using your card. I know you mentioned your area requires you to be 19, not sure if that still applies if you are applying online, in another state. Also, there's no real reason to get a card with an annual fee in this case. The main reason for an annual fee would be a lower interest charge - simply don't get charged interest, and you'll be better off with not having to pay for a card annually. Good luck. Keep in mind that credit takes time to build.   Your best short-term solution is to save enough cash to put enough of a down-payment that the lower loan-to-value ratio outweighs the lack of credit history.  If there's enough equity to ensure that the bank will get their money back if they have to foreclose, you will have a better chance of securing financing. In addition, the stability and consistency of your employment may also be a factor that makes it difficult for you to get a loan without a substantial down-payment. Finally, don't ignore the risk present in resting a property that you have a loan on.  Make sure you have a plan in place to pay your payments if the other half goes unrented for several months, or you risk losing the entire property. My advice is to rent somewhere else for enough time that you can save up a lot of cash to purchase a duplex rather than getting in a rush and doing something unwise (like apply for a bunch of credit cards you don't need). One possible route is to try to have no credit. This is different than bad credit. If you build up a good downpayment (20%), a number of banks would do manual underwriting for you.
"Note: this answer is true for the UK, other places may vary. There are a couple of uses for credit cards.  The first is to use them in a revolving manner, if you pay off the bill in full every time you get one then with the vast majority of cards you will pay no interest, effecitvely delay your expenses by a month, build your credit rating and with many credit cards you can also get rewards. Generally you should wait until the bill comes to pay it off. This ensures that your usage is reported to the credit ratings agencies. In general you should not draw out cash on credit cards as there is usually a fee and unlike purchases it will start acruing interest immediately. The second is longer term borrowing. This is where you have to be careful. Firstly the ""standard"" rate on most credit cards is arround 20% APR which is pretty high. Secondly on many cards once you are carrying a balance any purchases start acruing interest immediately. However many credit cards offer promotional rates. In contrast to the standard rates which are an expensive way to borrow the promotional rates often allow you to borrow at 0% APR for some period. Usually when it comes to promotional rates you get the best deal by opening a new credit card and using it immediately.  Ideally you should plan to pay off the card before the 0% period ends, if you can't do that then a balance transfer may be an option but be aware than in a few years the market for credit cards may (or may not) have changed. Whatever you do you should ALWAYS make sure to pay at least the minimum payment and do so on time. Not doing so may trigger steep fees, loss of promotional interest rates. There is a site called moneysavingexpert that tracks the best deals." Most banks offer a college card that has low limits so you can start building credit. Another good option is to get a rewards credit card and do your everyday spending on it, then immediately turn around and pay it. I have seen people that just overpay their credit card just to use it like a debit card, all while earning credit and getting rewarded for it.  I work for a bank so I see this alot. I take it the premise of the question is that we're assuming the person isn't worried about the morals. He's a criminal out for a quick buck. And I guess we're assuming that wherever you go, they wouldn't arrest you and extradite you back to the U.S. As others have noted, you can't just walk into a bank the day you graduate high school or get out of prison or whatever and get a credit line of $100,000. You have to build up to that with an income and a pattern of responsible behavior over a period of many years. I don't have the statistics handy but I'd guess most people never reach a credit limit on credit cards of $100,000. Maybe many people could get that on a home equity line of credit, but again, you'd have to build up that equity in your house first, and that would take many years. Then, while $100,000 sounds like a lot of money, how long could you really live on that? Even in a country with low cost of living, it's not like you could live in luxury for the rest of your life. If you can get that kind of credit limit, you probably are used to living on a healthy income. Sure, you could get a similar lifestyle for less in some other countries, but not for THAT much less. If you know a place where for $10,000 a year you can live a life that would cost $100,000 per year in the U.S., I'd like to know about it. Even living a relatively frugal life, I doubt the money would last more than 4 or 5 years. And then what are you going to do? If you come back to the U.S. you'd presumably be promptly arrested. You could get a job in your new country, but you could have done that without first stealing $100,000. Frankly, if you're the sort of person who can get a $100,000 credit limit, you probably can live a lot better in the U.S. by continuing to work and play by the rules than you could by stealing $100,000 and fleeing to Haiti or Eritrea. You might say, okay, $100,000 isn't really enough. What if I could get a $1 million credit limit? But if you have the income and credit rating to get a $1 million credit limit, you probably are making at least several hundred thousand per year, probably a million or more, and again, you're better off to continue to play by the rules. The only way that I see that a scam like this would really work is if you could get a credit limit way out of proportion to any income you could earn legitimately. Like somehow if you could convince the bank to give you a credit limit of $1 million even though you only make $15,000 a year. But that would be a scam in itself. That's why I think the only time you do hear of people trying something like this is when they USED to make a lot of money but have lost it. Like someone has a multi-million dollar business that goes broke, he now has nothing, so before the bank figures it out he maxes out all his credit and runs off. It can certainly help build a credit score, but remember that businesses gain credit differently from individuals.  Depending on the country, there isn't usually a national register of business credit ratings the way there is for individuals.  The credit record you'd be gaining is with your own bank only. Banks will usually base your business credit record on revenue and transactional loads rather than merely on having and holding a credit card.  That said, it isn't always that easy to get a business credit card and so it is a useful thing to have for credibility with clients (depending on the type of work you do). A credit card can also sometimes work out cheaper (and faster) for financing small overdrafts than a regular business overdraft facility.  That said, I've found that larger loans over a five-year term can work out much cheaper for an established business than they would for an individual, even where the business itself has no history of using credit. If you have no credit score it is generally far easier and more affordable to establish credit the cheapest way possible, which is usually in the form of a small credit card (student card if you are a student, low credit line unsecured, or even secured if you need). Your local bank/credit union will usually be keen to offer you something to start out, but you can also apply online to some of the major credit card vendors. As always, look out for annual fees, etc. In general, trying to get a larger loan to establish credit will cost you a lot as you will not qualify for any legitimate 0% or ultra-low APR car loans - those are reserved for people with established and generally pretty good credit. I expect you'll find a car loan that will have a lower APR than you could get investing your money otherwise - especially if you do not have established excellent credit - to simply be a phantom (you won't find it), and even if you could it is more risky than it is worth. Furthermore, if establishing credit is important to you (such as for buying a house down the road), you can build an excellent credit score without ever having a car loan. So you don't have to buy a car on borrowed money just to hope to get approved for a house some day - it's just not a requirement. Finally, I urge you to make a decision on the best car for you in your situation, ignoring the credit score - especially if you are more than 3-5+ years away from buying a house. Everything else about buying a car is more important - the actual cost of the car, year, mileage, suitability for your needs, gas mileage, maintenance and insurance costs, etc.  Then, at the very end of your decision making process, ensure that buying the car would not put you dangerously low on savings by squeezing your emergency fund. Decide if you really need a loan or as expensive of a car, considering the costs over the expected life of you owning the car (or at least the next 2-5 years). Never get trapped into just thinking about monthly payments, which hide the true cost of loans and buying beyond what you can afford to purchase today. Good credit is calculated (by many lenders) by taking your FICO score which is calculated based upon what is in your credit report.  Building credit generally means building up your FICO score. Your FICO score is impacted my many factors, one small one of which is your utilization ratio of your installment loans like student loans.  This is the ratio of the current balance to your original balance.  To improve your score (slightly) you would want a lower ratio.  I would recommend paying your student loan down to 75% ratio as fast as you can and then you can go back to $50/month. A much better way to improve your FICO score is to have revolving credit.  Your student loans are not revolving, they are installment loans.  Therefore, you should open at least one credit card (assuming you currently have none) right away.  The longer you have had a credit card open, the better your FICO score gets.  Your revolving credit utilization ratio is way more important than your installment loan ratio.  Therefore, to maximize your FICO, try to never have more than 10% utilization on your revolving credit report to the credit bureaus each month.  Only the current month's ratio affects your score at any given moment.  You can ensure you don't go above 10% by paying your balance before the statement cuts each month to get it below 10% way before any payment would be due.  (You should always pay your remaining credit card statement balance in full each month by the due date after the statement cuts to avoid any interest charges.)  Note that there is a slight FICO advantage to having at least one major bank credit card instead of just only credit union credit cards.  Also, never let all your revolving credit report a zero balance in a month, you must always have at least $1 reporting to the credit bureaus on at least one of your open credit cards or your FICO score will take a big negative hit. If you cannot get a normal credit card, go to a credit union and find one that offers secured credit cards, or a bank that does.  A secured credit card is where you place a deposit with the bank that they hold and give you a credit limit to match your security.  Ideally it would be a card that graduates to unsecured after your demonstrate good history with them.  For example, the Navy Federal Credit Union secured card unsecures for many people.  I also believe the Wells Fargo Bank credit card (you can join if there is a family member who served or a roomate who did) also will unsecure.  The reason you want it to unsecure and not be forced to open a new account to get an unsecured account is that you want your average age and oldest age of open revolving credit accounts to be as high as possible as this is another impact on your FICO score. Credit unions that anyone can join include, Digital Federal Credit Union, the Pentagon Federal Credit Union (which offers a secured card that does not graduate), and The State Department Federal Credit Union (also offers secured card that I think does not graduate). One other method to boost your FICO score is to get added as an authorized user on one of your parent's credit cards that has been open a long time.  Not all lenders will report such an authorized user, however, ones that are known to do so are: Bank of America, Citi Bank, and Capital One.  It is a good sign that it will report if they ask for the social security number of the authorized user. However, note that the Authorized User addition can have no impact if the lender is using one of the newer versions of the FICO scoring model, only the older versions reward you for the age of accounts for which you are an authorized user. A very long term boost is to open your first American Express card underwritten directly by Amex such as their Zync card which is pretty easy to get.  The advantage of American express is that they remember the date your first credit card was opened with them and if you open new accounts in the future they will back date the date of their opening to match the date your first card was opened.  If you let your membership lapse, be sure to record the account number and date opened in your personal files so that you can help them locate it again if you reopen as they can have trouble if it has been on the order of ten years or more. Finally, note that the number of accounts opened in the last twelve months is a small negative mark on your score (along with number of inquiries), so if you open a lot of accounts all at once, in addition to bringing down your average age of accounts, you will also get dinged for how many were opened in the last year. I just want to stress one point, which has been mentioned, but only in passing. The disadvantage of a credit card is that it makes it very easy to take on a credit. paying it off over time, which I know is the point of the card. Then you fell into the trap of the issuer of the card. They benefit if you pay off stuff over time; that's why taking up a credit seems to be so easy with a credit (sic) card. All the technical aspects aside, you are still in debt, and you never ever want to be so if you can avoid it. And, for any voluntary, non-essential, payment, you can avoid it. Buy furniture that you can pay off in full right now. If that means only buying a few pieces or used/junk stuff, then so be it. Save up money until you can buy more/better pieces. The whole point of a credit report and, by extension, a credit score, is to demonstrate (and judge) your ability to repay borrowed funds.  Everything stems from that goal; available credit, payment history, collections, etc all serve to demonstrate whether or not you personally are a good investment for lenders to pursue. Revolving credit balances are tricky because they are more complicated than fixed loans (for the rest of this answer, I'll just talk about credit cards, though it also applies to lines of credit such as overdraft protection for checking accounts, HELOCs, and other such products). Having a large available balance relative to your income means that at any time you could suddenly drown yourself in debt.  Having no credit cards means you don't have experience managing them (and personal finances are governed largely by behavior, meaning experience is invaluable).  Having credit cards but carrying a high balance means you know how to borrow money, but not pay it back.  Having credit cards but carrying no balance means you don't know how to borrow money (or you don't trust yourself to pay it back). Ideally, lenders will see a pattern of you borrowing a portion of the available credit, and then paying it down.  Generally that means utilizing up to 30% of your available credit.  Even if you maintain the balance in that range without paying it off completely, it at least shows that you have restraint, and are able to stop spending at a limit you personally set, rather than the limit the bank sets for you. So, to answer your question, 0% balance on your credit cards is bad because you might as well not have them.  Use it, pay it off, rinse and repeat, and it will demonstrate your ability to exercise self control as well as your ability to repay your debts.
