How to title property to limit personal liability and risk?

[Sandy Hatch]

I want to start investing in multifamily units, but my wife doesn't want to risk having personal liability for investment assets. I know that if you take a residential loan out, and then transfer to an entity (LLC, S corp etc) that there is a due on sale clause that can kick in. My question is what is the best way to limit personal liability for an investment property? My wife objects to putting our personal assets at risk for such an investment. I would ask this question for both residential (4 units or fewer) and commercial (5+ units).

I greatly appreciate any help!
