A jumbo loan is a mortgage for the ammount that exceeds the Federal Housing Finance Agency's approved loan limits for a particular state. Real estate prices vary greatly in different regions of the United States, so the limit above which a loan acquires jumbo status ranges from about $400,000 to $800,000.

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.

A loan recast is the payment of a fixed amount during the term of the loan agreement aimed to cover the principal of the loan so as to reduce subsequent monthly payments for the remainder of the term of the agreement. Generally, a loan recast is used in mortgage lending by people who suddenly received a large sum of money (e.g., an inheritance).

A recourse loan or debt entails personal liability of the borrower. A non-recourse loan does not allow the lender to claim anything other than collateral. For example, if someone fails to repay a non-recourse mortgage loan, athe lender may only foreclose on the real estate that was the collateral.

A payday loan is a small short-term unsecured loan, usually issued by microfinance institutions. The issuance of such loans depends on the consumer's previous wages and employment history. Legislation on payday loans varies widely from state to state. To prevent usury (unreasonable and excessive interest rates), some jurisdictions limit the annual interest rate a lender can charge. Additionally, payday loans assume a higher rate of default on the loan.

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.
