I leased my boy while he was up for sale. He was a Euro Import that was doing the meter twenties and within a few weeks he was set to be trailered off to his new home. Which was totally unacceptable to me. The original owners listened to my plea for whatever I could do to keep him, and they allowed me to make payments. Most owners really want to see their horses go to a great home... Even if that means that the great home can only afford payments! (how many people do you know with 10 grand in their wallets!??)
It's always an option!
