Per my understanding, when filing for rental income during our annual income tax filing, net rental income needs to be declared by deducting:

- Assessment tax
- Quit rent
- Property repairs
- Fire insurance
- Rent collection fee
- Rent renewal fee
- Interest on home loans
- Maintenance fee (strata properties)

Anyone has any idea how 'interest on home loans' are being calculated? Since the first 10 years or so, most of our mortgage repayment goes to paying only interest rather than the principal amount.

Any guidance where can we get this amount?
