Well, make a budget, all of your inputs and outputs. Your inputs are going to be seed, fertilizer, equipment, land cost whether thats rent or payments, always figure the cost of rent in even if you own the land and have it paid for because that is the money you could get from renting it out, custom farm work if you don't have the equipment, labor, insurance, im sure im forgetting some also. Your outputs will be your corn and beans, and any payments you get from the gov't. You will not be able to make a living off corn and soybeans on 80 acres in Iowa. So your options are expand, do it on the side as a hobby, rent the land out, or find a niche or specialty market. Because chances are you will not be able to sell all of your crop for top price with the fluctuations in the market right now. You must also figure on getting health insurance from somewhere whether you pay for it or your spouse works off the farm and you are covered through them. Takes a lot to make it full time farming in Iowa these days and have the quality of living that most people want. Srry to be so negative but thats the reality of it. Good luck to you.
