The only thing you lose is mortgage interest decoction, but if your business is profitable, you can claim the 20% pass through tax deduction. it is about a wash on taxes, but you are not stuck paying all that interest.

You wont change this by paying off the house but you will reduce your personal out of pocket by offsetting smaller decoctions with smaller monthly costs Just leaving the cash in the bank is worthless, paying your rental off and then getting the money back slowly every month might not be the best answer either.

I just bought one in Dec, Oct and sept. because the numbers still work for me.
