Payment INTO trust account

Hi,

I'm a real estate investor with a few doors.  In Ontario, we hold the last months of rent in trust until the tenants move out at which point it will be used to pay the rent.  We also need to "pay" interest on that money.  I'm just not sure I'm doing this properly.

Here's my setup.

I have a bank account set up for the property.  This account tracks and actual bank account.  I have multiple sub-accounts to track different things:

123 Main Street

• Main Account
• Last Months deposit Unit 1
• Last Months deposit Unit2
• Contingency Fund
• Vacancy fund

I set up my property as a customer and my tenant as "sub" customers.

I set up an "Other Current Liabilities" account named "Last Month Deposits" with sub-accounts. 

Last Month Deposit (in trust)

• 123 Main St Unit 1
• 123 Main St Unit 2

I created a sales receipt for the deposit from the Tenant.  I deposited the money into the "123 Maint St: Last Months deposit Unit 1"  bank account.   The product/service is the "Last Month Deposit (in trust): 123 Main St Unit 1" trust account.

Now I need to "pay/transfer" the interest into the trust account from my "main account" but also transfer the money to the "Last Months deposit Unit 1" bank account.  This is where I'm not sure I'm doing it properly. 

All I did is:

1. Generate and expense from the "Main Account" and use the tenant as the "Payee"
2. Transfer money into the "Last Months deposit Unit 1" from the "Last Month Deposit (in trust): 123 Main St Unit 1".

Is there some other way I should do this or does this sound right?

Thanks!
