 Just stop. No, do not pay this off. And it's a rental property. You're making $11,000 a year on the rental unit and you've got like 85 grand of equity. That's an amazing return. So no, do not use $2,000 extra per year to pay off the principal early. Just leave it alone. Let it do its thing, okay? Do not make every other week payments on your primary mortgage. It's 2.875%.
