DH 10: Limited denial of deductibility: simplified calculation of interest affected
or “Calculating how much interest you can't deduct for residential property loans”

You could also call this:

“How previously denied costs are handled when you sell a disallowed residential property”

If you own a disallowed residential property and you’re not allowed to claim some costs as a deduction, here’s what happens when you sell it:

If you sell the property within two years and make money from the sale, the costs you weren’t allowed to deduct before can now be treated as part of the property’s cost. This happens in the same year you sell the property.

If you rent out the property and then sell it, making money from the sale in a way that’s not covered by the two-year rule, you can claim those previously disallowed costs as a deduction in the year you sell. However, there are special rules about how much of these costs you can claim each year.

Remember, these rules only apply to costs that weren’t allowed as deductions before, and only when you sell the property.
