I rent out 20% of my home (an in-law unit to be precise) and therefore have always written off 20% of utilities paid for the year.
I recently got solar, so now my utilities will go down significantly, but will have a monthly loan I need to pay off. Since this is an improvement to the property, am I still entitled to write off 20% of what I pay for the solar panels each year? Would this cause problems for the tax credit we will receive come tax time?
