10 years ago, my wife and I took out a joint second mortgage against our jointly owned main home to purchase a jointly owned second home. We used the second home ourselves (for work reasons), but with retirement have now rented out the second property. Given that the additional mortgage on our main home was used solely to fund the purchase of the second property, can the interest from that second loan now be applied for a tax credit against rental income from the second home?
