ORS § 407.305
When a veteran who is eligible for a loan under this chapter and Article XI-A of the Oregon Constitution seeks to acquire a home or farm that is serving as security for a previous loan made under this chapter, the veteran may choose either to receive a new loan for the property or to assume the previous loan. If the loan balance for the loan being assumed does not exceed the amount of the veteran's entitlement under ORS 407.205, the interest rate to be paid on the assumed loan balance shall be the rate per annum prescribed under ORS 407.315. In addition to the amount assumed, the veteran may apply for and receive additional funds to be applied to the purchase price. The interest rate to be paid on the additional funds shall be the rate per annum currently prescribed under ORS 407.325. The sum of the assumed loan balance and the additional funds shall not exceed the amount of the veteran's entitlement under ORS 407.205 or the maximum loan amount prescribed by ORS 407.205(3)(b) or (c). An assumption or an assumption with additional funds under this section shall be deemed to be one loan and the veteran making the assumption or the assumption with additional funds shall be deemed to be a borrower for the purposes of ORS 407.145, 407.205, 407.215, 407.325, 407.385, 407.465 and 407.475.
