Is there a way to avoid a due on sale clause for my current property and duplex but still operate them as rentals and be taxed as a business?

I admit there are bad turnkey operations out there, but a good product that cash flows and isn't in negative equity sounds like the goal of most investors.

My personal feeling is that it's a lot of risk, and you should focus all of your energy on your core business, not real estate.
