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.

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.

A non-QM (Non-Qualified Mortgage) loan is a mortgage loan designed for borrowers who cannot qualify for a standard mortgage. Non-Qualified Mortgage loans are assessed using non-standard evaluation methods, usually without regard to credit score and similar criteria applied to Qualified Mortgage loans.

An FDA (Federal Department of Agriculture) loan means a government low-interest loan system designed for people who are unable to take advantage of a standard mortgage. The main features of FDA loans are that there is no down payment and that the borrower may only purchase a home in clearly designated rural or suburban areas.

An installment loan is a very broad term that essentially includes any loan with a clear repayment schedule and number of payments (installments). Therefore, in this sense, a standard mortgage contract is also an installment loan.

A personal unsecured loan is a personal loan issued by a lender without any collateral from the borrower's side. Of course, unsecured loans are accompanied by an increased risk of the borrower's default, so the interest rate is much higher and the maximum loan amount is much lower than for secured loans.

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.

Of course, it very much depends on the country/state, the type of credit, your credit score, and whether the credit is secured or not. But in the broadest sense, for people with a credit score exceeding 600, an interest rate of 10-20% might be considered as good.

Before taking out a consumer loan, it is worth calculating all the interest and overpayments in advance, so that you understand the acceptability of the loan offer before applying. This way you will know in advance how much you will need to pay each month to repay the loan. Loan payments are most often calculated using two payment schemes: annuity and differential. Which of them is applied in a particular proposal is specified in the loan agreement. Knowing the formula of a particular scheme, you can calculate the amount of the monthly payment and know in advance its full amount with all the overpayments. In rare cases, a bank offers to choose the scheme.

Loan default is a default on a loan agreement, i.e. failure to timely pay interest or principal on a debt obligation or under the terms of a bond issue agreement. Consequently, a person who defaults on a loan is considered a loan defaulter. Penalties for loan defaults are applied according to the type of loan and the specific terms of the contract.

The thing is, the Department of Veterans Affairs doesn't confirm the loan but makes specific requirements that appliers must follow to obtain the VA guarantee. One of those requirements strictly limits the amount you can loan based upon a formula called your 'debt to income ratio' or just 'debt ratio.' This parameter is a percent-denominated value which is calculated by dividing exact debt obligations by your monthly income.
