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 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.

First of all, it all depends on what type of credit you are interested in and for which exact amount you are expecting. The requirements will vary depending on the particular loan provider, as well as the specifics of state or national lending laws. In general, though, it's usually a set of documents proving your identity and source of income, as well as your ownership of the collateral.

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.

Gradual repayment of the loan through regular payments of principal and accrued interest is the amortization of the debt. Specific repayment terms are determined according to the concluded loan agreement and are fixed in the payment schedule. The payments are broken down for the entire term of the loan agreement and consist of the 'principal' (original amount of the loan) and interest. The amount of the amortization charges in this case shows the total amount of repayment at the moment.

The minimum amount of down payment for a conventional loan is 3% of the loan amount. However, as a rule, this figure is higher, because credit history and other factors are taken into account, which increase the risks for the lender and require appropriate compensation.
