(1) length of the marriage;
(2) value of the property owned by the spouses;
(3) age of the spouses;
(4) health of the spouses;
(5) ability of the spouses to earn a living;
(6) contribution of each spouse to accumulating the property; and
(7) income-producing capacity of the property owned by the spouses.
