Refinancing commercial real estate can be done for a variety of reasons. In many cases, borrowers get cash out refinances in order to free up capital to make renovations/property improvements, or to invest in other properties. In other situations, borrowers may wish to refinance a commercial property in order to achieve a better interest rate or a longer amortization, which can help them increase monthly cash flow.
Securitization is the process in which commercial or residential real estate loans are pooled together, packaged into a financial product, and sold to investors on the secondary market. Not all types of commercial real estate loans are securitized, but many are. For instance, CMBS and conduit loans are always securitized and sold as commercial mortgage backed securities. In contrast, many, but not all HUD multifamily loans and Fannie Mae/Freddie Mac multifamily loans are securitized.
