Loan amortization is the process of gradual repayment of a loan by making regular payments of principal and interest on the use of credit funds. In essence, loan amortization is a repayment of the loan on the terms and conditions agreed in the loan agreement and over a specified period.

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.

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.

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 (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.

In order to qualify for a FHA (Federal Housing Administration) loan you must meet certain requirements. First of all, you must have a sustainable income. Then, you should have at least 3.5% of the total cost of the house as a down payment. Your FICO score should be no less than 580. Finally, your credit history must be normal and the house you are going to buy should cost no more than the amount you applying for.

In essence, a loan estimate is the same thing as a loan disclosure, only in a preliminary form and solely for introductory purposes. It is a document containing detailed information on the selected loan proposal, including the interest rate, term, repayment schedule, etc.

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.

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.

Loan origination fee is an upfront fee associated with opening an account with a bank, broker, or other processing entity in connection with obtaining a loan. It is usually a fixed amount, but sometimes the fee is spread over the term of the loan or integrated into the interest rate. It is worth adding that in some countries, loan fees are prohibited at the state level.

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.
