Why not pay off a piece of property?

[Henry Hodges]

When listening to the recent podcast (episode 263) with Bruce Petersen, Bruce mentioned that you should never try to pay off a loan on a property.  He is mainly involved in much larger scale things than most people are, but I cannot understand why you wouldn't want to pay it off sooner than later, other than I have heard people say that you could be using your money else where.  How would it differ depending on the size/price of the property?  Does any one have any insight on this?

Thanks!
