So 30k in interest payments on a primary would only net most people an $800 tax deduction since they would have already got the standard deduction by default, where as 30k in rental interest would translate into 30k in deductions.This means that for an awful lot of people, they effectively don't get to deduct the interest on their primary.Keeping the loan on your rentals, while getting rid of the loan on your primary also helps from an asset protection side of things.
