I started farming in the early 1970s while a Senior in High School after I turned 18 with money borrowed from the Farmer Home Administration FHA (the part of the USDA that loaned money for farmers in need). Yes, there was a lot of paperwork even then. I discovered that quite a few of my neighbors and other farmers I delt with also had started farming with FHA help and loans. I know that was then, but a couple decades later I know of at least 3 and I suspect more used FHA to start farming and eventually bought farms as well. Alot of us complained about the paperwork and how much they controlled our farms, but beggars can't be choosy. I even heard one guy that complained about FHA but admitted he made more money when he was a borrower from them.
You have made an excellent start to farming. I commend you! No matter who you borrow from will want to get their money back eventually and no banker really wants to sell you out. They want you to succeed. (and borrow more money so they can make more money) "Neither a borrower or lender be" sounds good, but in modern agriculture it is extremely difficult for most of us. Credit is a tool to be used wisely. Good Luck!
