There are several classifications of loans, so let's consider the most common one. According to it, there are three loan categories: bank, commercial and state. In its turn, bank loans are divided into personal, mortgage, loan on overdraft, factoring, forfeiting and intrabank loans. Commercial loans may be of the following types: signature, trade and advance. Finally, the state category is subdivided into state loan, subventions, grants, transfers and state tax loan.

The key difference between secured and unsecured loans lies in their very name. Secured loans are guaranteed by the borrower's property or assets, which protects the lender to a much greater extent. Unsecured loans do not require collateral, so there is more risk for the lender. These risks need to be compensated somehow, so the terms and requirements in unsecured loans are tougher than in secured loans.

A payday lender is a lending institution that specializes in reviewing applications and issuing payday loans. As a rule, we are talking about microfinance organizations that offer unsecured short-term loans at high interest rates.

A loan to value (LTV) ratio shows how much of the value of the property a borrower acquires a creditor is ready to lend him or her. Since this is usually a mortgage loan, the LTV essentially shows how much of the value of the property you already own and how much you are able to pay as a down payment. This will directly affect the interest rate and terms of the loan. Moving to specific numbers, a good LTV ratio would be 80% for conventional loans and 95% for FHA loans.

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.

The interest rate is the portion of the principal amount of the loan that the borrower must overpay to the bank for using its money. The interest rate can be calculated according to an annuity or a differential scheme. In the first case, the total amount of the loan is divided into several months or years in equal installments. With the second, the rate is charged on the balance of the loan and decreases with each month. Rarely a bullet scheme is utilized where the interest and the principal amount of the loan are repaid separately (first the principal and then the interest, or vice versa). If the rate changes at contractually specified periods, it is considered floating. If newly accrued interest is added to the interest calculated for the previous period (interest-on-interest scheme), it is considered capitalized.

Broadly speaking, a security loan is a credit granted by a financial institution against the security of the borrower's property or assets. A security loan, in turn, has several varieties and classifications, in particular, regulating the extent to which the borrower is liable to the lender in the event of default.

In lending industry, subprime loan means lending to individuals who have difficulties with meeting repayment schedules or other key terms of the loan agreement. Borrowers with a FICO score below 600 are usually considered subprime, although this threshold changes over time and other criteria are added to it.

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.

A fixed rate is a system of accruing interest in which the loan payments will be calculated at an unchanging interest rate for the entire term of the loan. That is, the borrower receives the amount at a specific interest rate, which is prescribed in the contract and does not change during the loan period.

To understand the big picture when choosing a loan offer, it is very useful to calculate the actual annual percentage rate (APR) on the loan. It includes not only the interest rate, but also all the additional fees and costs explicitly or implicitly included in the loan agreement. In principle, APR can be calculated manually using the formula, but there have long been special and very handy calculators for this purpose on the Internet.
