@SurfNTurf - I think that a cashier’s check is like a money order that is drawn from the same issuing bank. For example, I needed to get a cashier’s check from my bank when I was registering for a real estate auction. Sometimes there are fees associated with it, but my bank does not charge for a cashier’s check.
However, when I am renting out my condo, I always require a money order for the security deposit and subsequent rental payments because many of the renters are out of state because it is a resort property.
I like the security aspect of the money order and I don’t have to worry about the checks bouncing. I think that this is why some people prefer a money order. I know that I can deposit my money order at my bank with no problem. I think that the two types of checks serve basically the same purpose. They are just more secure types of payments.
