2. The separate property percentage interest is determined by crediting the separate property with the down payment and the full amount of the loan on the property less the amount by which the community property payments reduced the principal balance of the loan.
3. This sum is divided by the purchase price. The resulting figure is the separate property percentage share.
4. The community property percentage share is determined by dividing the amount in which community property payments reduced the principal by the purchase price.
5.
