Always keep track of phone conversations by writing down a summary of the call, date, time, and name of the bank representative spoken with. When important documents are mailed, invest in the extra protection of tracking receipts. Certified letters should be sent with a return receipt request in case it is necessary to provide evidence the documents were received.
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.
