Scaling with Assumable loans

[David Cunha]

Has anyone scaled through assumable loans? Ideally, if it's a FHA assumable loan the property has to be your primary residence for a year. Then you're free to rent it out. So if every year I would buy an assumable rate property and live in it for a year then rent it out and repeat this. I could end up with a low interest rate for every property I acquire. Is there holes in this strategy?
