Borrow to invest
What are CRA's rules on interest deductibility with multiple loan accounts to fund an investment. For eg.
Account 1: a mixed use loan account currently 90% investment use, 10% personal use
Account 2: a 100% investment use account
The idea is to combine both 90% of fund in account 1 + 100% of fund in account 2 to purchase one single investment. The investment will generate monthly cash distribution (including some portion of ROC). The monthly distribution will deposit directly into account 2. Plan to move part of the monthly distributions from account 2 to account 1 since it also contributed 90% of the fund for the investment, so want to apply part of the monthly distributions to pay the interest incurred in account 1.
Question is - would withdrawing from account 2 and deposit into account 1 turn account 2 into a mix use account as well ? According to CRA rule, for interest expense to be deductible, the fund needs to either reinvest or pay down the debt. In this case, the fund withdraw from account 2 and deposit into 1 is effectively paying down part of the investment loan. Only thing is, account 1 already being a mix use account, so any deposit made will be split proportionally.
