Investment loan are around 1% over OO
That's what I've seen as well. If you don't mind moving, and have it down to a science like I do, you can also occupy the property then turn it into a rental after a year or two. I will be living in my current home for another year before I turn it into a rental, so total of 2 years. Largely because I have not found another home to buy yet, but also because I may sell this one due to the fact that it is in an HOA, so I don't want to have to move back into it if there is a problem with the HOA and they ban rentals, which they can do by law in WA. NEVER buy a house with an HOA. NEVER. EVER.
Also, it is my understanding you can buy the interest rate down, even on a rental property, and depreciate the extra points paid over a number of years. Food for thought. The government wants you to own property and they give very generous ways to make it work for you.
