nmfruit, the chance isn't extremely small, it will just more than likely take a very long time. Maybe 7-12 years. There are 3 reasons for this. First it was grown from seed, so that takes a while to get to a reasonable size. Second it is not grafted onto different rootstock, so that means the tree is not going to begin fruit production early in it's life (the first several years all the energy is going to go into growing branches). Third, trying to grow a fruit tree inside in a pot with limited root space is going to hold back growth. To some extent the second and third points here will kind of mitigate each other, but only to some degree. It's a tropical fruit tree and the soil needs to remain warm and the leaves need sunshine. The leaves can also be prone to drying out indoors if a heater is being used (as cold air is warmed it can hold more humidity and will begin sucking up moisture).

johnnyk08, I think your plant needs a little more light, and it's very important you keep the humidity high so the leaves do not dry out. one way to accomplish this could be to wrap the plant in a clear plastic bag, or put it in a greenhouse space with a pan filled with water. Make sure the soil is kept moist and never dries out.
