Paid cash for the purchase (a private party), titled the trailer and paid taxes & registration. In my opinion, the ability to execute a cash purchase always puts the buyer in the strongest negotiating position possible. Then shopped for the best financing options and found 3.75% fixed for 60 months from a local Credit Union. I financed 100% of the purchase price; late model used trailer purchased at NADA wholesale. Excellent credit. As has been mentioned, cost of money is cheap and the return I expect to, and have historically, earned on my investments exceeds the 3.75% cost of borrowing.
