A USDA (United States Department of Agriculture) loan is a mortgage loan with no down payment issued to U.S. citizens for the purchase of real estate in rural and suburban areas. As a rule, the target audience of USDA loans are people with incomes below average, who cannot afford to buy a house in urban areas, as well as people who, for some reason, are unable to conclude a standard mortgage agreement.

A VA loan is a mortgage loan secured by Veterans Benefits Administration that is designed for U.S. military veterans and certain members of their families. It is important to understand that the Veterans Benefits Administration is not a lender, it only supervises terms and conditions of VA loans issued by private lending institutions, including banks.

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.

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.

Each banking institution has its own procedures, rules and methodologies for examining and analyzing the creditworthiness of a potential borrower applying for a loan. The underwriting procedure results in a positive decision on the loan application or refusal to grant a loan, or a compromise decision: granting a loan, but in the amount and/or under the conditions that are favorable to the bank, even if they differ from the client's expectations. That is, a credit underwriter is a specialist who makes such decisions.

Collateral is a guarantee for the lender to get all the funds due under the loan agreement. In case the borrower does not fulfill his/her obligations or does not fulfill them to the full extent, the corresponding debt is to be repaid at the expense of the collateral. Collateral can be represented by residential and non-residential real estate, motor vehicles, precious metals, securities, etc. However, in fact, banks determine the list of property taken as collateral when granting loans. The property pledged as collateral under the loan must be necessarily evaluated.
