Why your marginal rate matters for mortgage strategy

Deductible interest (rental HELOC, investment loans) saves you tax at your marginal rate, not your average rate. The higher that number, the more a strategy like Rental Cash Damming is worth pursuing.

Why your marginal rate matters for mortgage strategy

Strategies like Rental Cash Damming and readvanceable mortgages work by converting non-deductible interest into deductible interest. What that deduction is actually worth to you depends on your marginal rate, not your average rate, since it's the tax on the next dollar you'd otherwise pay that gets offset. The higher your marginal rate, the more these strategies are worth exploring.
