I am 18 mos into my Chapter 13, I am making monthly payments and I have 3 pieces of land for sale. When I make all my payments at the end of 60 months what happens if my land does not sale to make up the remainder of what I owe. I am set to pay back 100%, but the value of my land and my payments are higher then 100%. Also, my plan base is half of what I owe, what significance is that?
