There is some good advice here, and some parroting.

Now, saying if you fail a lease purchase you will lose everything, go finance a truck is one of the most bass ackwards statements I have ever heard. Lets analyze this.

You go, put money down on a truck, you own the truck, or more realistically the bank owns the truck. You hit hard times, you can't make your payments. The bank doesn't care, they want their money. The truck gets repossessed, sold at auction, and you could still be stuck with a bill in the thousands because a repossessed vehicle never brings what is owed to the bank at auction. Your credit now shows a repossessed vehicle and a debt to a financial institution. Oh and during these hard times your bills weren't getting paid, your utilities get shut off. Ok this is worst case.

You lease a truck. You did your research and leased onto a company that lets you get your own loads. You are now in charge of your destiny. Should you fail you turn in your truck (you did research and make sure you got a walk away lease right?). No debt to a bank, no money owed with nothing to show for it.

Now I will say this, go into a L/P unprepared and you are set up for failure. I don't care if you drove a company truck for 20 years. Have you ever made a business plan? Do you understand how taxes work for an owner? Do you know how to use load boards and brokers? Do you understand IFTA and effecient fuel routing? Did you research the laws and your rights when it comes to lease contracts? Do you know anything about freight areas and rates?

This is all stuff I studied, some of it I am still learning. I have the added benefit of no risk as My income is not necessary for our household so I can make mistakes. If you don't have that kind of security be very careful and good luck. In the end you listen to advice then make whatever decision you feel is right for YOU, no one else can make that decision.
