AS long as you have PCF, you could have 25% interest, and if your DP didn't change, your cost would remain limited to the DP.The correct way to look at all of this isn't "what does a property cost me to own", but rather "what does a property cost me to control".Now, the interest rate DOES impact the CF, but as you've already noted it would take 42+ months just to break even.

That would be a bummer to find out after the fact.If you still have a loan on your duplex and pay a mortgage, most banks will have a "due on sale" clause if you transfer the title of the property from your personal name to the LLC, forcing you to pay the remaining loan amount immediately.
