Result Summary

Enter all fields to surface real-time boot estimates. Negative amounts will be treated as zero for compliance purposes.

Cash Boot

Cash received or withheld at closing becomes taxable boot. Plan to roll all net proceeds into the next purchase whenever possible.

Mortgage Boot

Mortgage boot occurs when your new debt is lower than the debt retired on the relinquished property. Increasing leverage or adding cash can close the gap.
