The valuation is discounted for selling costs if repayment of the loan is dependent on the sale of the collateral. If repayment will come from rental income of the property, the valuation is not discounted for selling costs.

[2] The Company markets other real estate owned both independently and with local realtors. Properties marketed by realtors are discounted by selling costs. Properties that the Company markets independently are not discounted by selling costs.
