Prior to entering into a loan agreement, the "borrower" first makes representations about his affairs surrounding his character, creditworthiness, cashflow, and any collateral that he may have available to pledge as security for a loan. These representations are taken into consideration and the lender then determines under what conditions (terms), if any, they are prepared to advance money.
Always obtain loan agreements in writing and read the fine print. One of the biggest mistakes borrowers make is entering into verbal agreements. If things go wrong there is no evidence to prove the case. Debtors should know the number of deferred payments, payment schedule, fees or penalties, and how the lender reports suspended payments to credit bureaus.
For commercial banks and large finance companies, "loan agreements" are usually not categorized although "loan portfolios" are often broadly characterized into "personal" and "commercial" loans while the "commercial" category is then subdivided into "industrial" and "commercial real estate" loans. "Industrial" loans are those that depend on the cashflow and creditworthiness of the company and the widgets or service that it sells. "Commercial real estate" loans are those that repay loans but that depend on the rental revenues paid by tenants who lease space, usually for extended times. More granular categorizations of loan portfolios exist but these are always variations around the larger themes.
If you have any queries in future, then you should be able to easily contact the lender. For this purpose, you should ensure that the company name, corresponding address and the phone number are mentioned in the loan agreement than the details about the agent who has been processing the loan for you.
