With a variable rate loan, the interest rate you pay will change periodically based on overall market conditions. How often this resets varies depending on the lender, so be sure to note how often your rate will change. Your lender may also offer a low introductory rate for a short time.
A business entity’s name is the name under which you conduct business. You may use a DBA (“doing business as”) if you don’t want your business name to be the same as your own personal name. If you do decide to operate under a different name, you would need to register your DBA with your state, county or city.
