You can write off the interest anyway, whether it is your home or a rental.
I own several rental properties, so I know a lot about this. I'm happy to answer any questions.
One thing, you want to make sure you want to own rental property. It's not for everyone. Do you really want to be a landlord or do you just want to make money from your house? If you don't have the genuine desire to be in the business and have the thick skin and dedication to do justice to it, it is probably not a good idea.
If you do, though, more power to you.
