"Insurance" organizations, who collect premiums for providing either life or property/casualty coverage, created their own types of loan agreements. "Banks" and "Insurance" organizations loan agreements and documentation standards evolved from their individual cultures and were governed by policies that somehow addressed each organizations liabilities (In the case of "banks," the liquidity needs of their depositors; in the case of insurance organizations, the liquidity needs associated with their expected "claims" payments).
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.
It is best to obtain a real estate forbearance agreement when deferring mortgage payments. Forbearance agreements prohibit lenders from commencing with foreclosure action unless borrowers' default on the contract. This is of particular importance when obtaining mortgage deferment to prevent foreclosure.
The interest rate for these types of loans is plus 1 percent of prime and is adjusted monthly. For these types of loans, borrowers are completely responsible for all third party costs and points can be bought with these types of loans to keep long term costs down.
