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.
Though you might be taking the loan for emergency, it is quite important that you should check the various alternatives for the loan before deciding on the final selection. In general, the loan agreement should contain various fees that would be charged for the loan being credited into your account which is called as the processing fee.
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.
These are just a couple of reasons why people need the money. The most common financial resource for these common problems is to get a loan. Anytime you are considering getting a loan from a financial or lending institution, it is imperative that you must sign a loan agreement.
