A finance charge on a loan is the sum of all interest and other charges and costs, including one-time charges, that the borrower will pay over the life of the loan agreement, that is, from the time the loan is signed until the last payment is made and the loan is closed. Thus, a finance charge on a loan includes not only the interest rate, but also origination fees and insurance.

An unsecure loan is a loan agreement that does not include any collateral on the part of the borrower, against which the lender grants the requested money. Large loans and mortgages are rarely granted without collateral, which can be either property (movable or immovable) or the borrower's assets.

Loan security is a mechanism for guaranteeing the repayment of a loan, which protects the rights of the creditor. A borrower can leave some tangible assets (such as a car or real estate) as security for a loan, which then becomes a secured debt to the creditor who issues the loan. Thus, the loan is secured, and if the borrower defaults, the creditor takes possession of the asset used as its security.

A pay day loan is a type of short-term personal credit without collateral. The service got its name due to very popular need among the population to urgently get a small amount of money until the next paycheck. Pay day loans are mostly issued by microfinance organizations, but large banks do not refuse this segment of the credit market either.

Credit is an economic contractual relationship in which one party receives money, goods or property from the other party, not prohibited by the relevant legislation, and promises to provide reimbursement (payment) or return the resources in the future. In fact, credit is the legal formulation of an economic obligation.

A loan to value ratio is an indicator determined by dividing a loan amount by the value of the assets or property for the purchase of which the loan is taken. In simple terms, a loan to value ratio (LTV) shows what share in the cost of the property to be purchased on credit represents the loan. LTV exceeding 80% is considered to be one that is associated with higher risks, so lenders usually force the borrower to insure such a loan.

Predatory lending is the practice of issuing loans with extremely high interest rates. Predatory lending methods include direct deception of borrowers, aggressive sales techniques, taking advantage of borrowers' financial unawareness, confusing contractual terms, and so on. In some countries, predatory lending is illegal.

A HELOC (Home Equity Line of Credit) is a loan with an agreed repayment period, in which the borrower's real estate or his share in the real estate is pledged as collateral. In this case, the borrower does not receive the entire amount, as in a conventional loan, but gets access to a credit line, which may be then used at his or her own discretion and in any amount.

A jumbo loan is a mortgage that exceeds a certain limit set by the U.S. government. It should be noted that the specific value for a loan to be called jumbo varies for each state, mortgage type, and year. For example, in 2021, the limit on an FHA loan for a single-family property in many states is $548,250.

A loan disclosure is a document or set of documents in which the lender is required to set out all of the terms and conditions of the loan you applied of (including any additional fees, charges, insurances, etc.) in a completely transparent manner and describe all details of the handling and use of funds and data.
