That's a decision you'd have to make with the help of someone like a CPA. There are very many reasons why doing one or the other (or neither!) might be best for YOU, at this time in your life.

Depends upon your goal. If you want to continue having some rental income, then pay off the home that you would prefer renting out and live in the other one. Of course, I am not understanding if you have a huge amount of money to pay it off now, or are you saying that you can pay it off in several years?

You would have to edit on that for me to give you a better answer. Hope you do because did you know that you can even answer your own question?

The bank doesn't own the houses - you do. What's the point of moving? You want to be able to claim the mortgage interest as a primary residence?

How in the hell would we know that?

Personally, I would pay off the house that has the highest interest rate and/or the higher payoff amount, unless there is some tax advantage to one or the other.

I own two homes, well the bank owns two homes that I am buying. One of the homes I live in and the other is a rental property of mine. My question is should I try to payoff the house that I live in and then move into the rental that I have and rent out the house that I paid off and use the money to payoff the other house or use that money to buy another rental property.
