To isolate the effects of cash flow and appreciation, I ignored factors such as inflation, rent increases, and other real-world costs and expenses.As you can see, appreciation can generate significantly more profit than cash flow.

Is there a process for making this legal, or am I SOL and would have to evict the illegal unit?

@Brady Beshear Airbnb can fill a calendar but if any newbs are reading this do not isolate yourself to one platform it’s a rookie mistake IMHO.

It helps to have enough space to isolate and get personal time when desired. 

The drawback however is that there is an isolation in those neighborhoods.

.. im not saying there cant be deals but you just have to weigh the risks .. that situation was pretty isolated .. the problem the banks had was they were dealing with somebody who read up on the laws .. so when he was offered a lease he decided to offer the owner a decent but hugely discounted price for a 5 year pre paid lease .. .. he knew that the banks could not show it to sell if it got foreclosed on and also knew that investor  in there right minds would  buy a property, not only sight unseen but then have to wait the remainder of the lease with no sorce of income ( remember the occupant had a 5 year prepaid lease ) and he then knew that nobody that wasnt a investor would pay cash for a place sight unseen and still have to go through a eviction process .. so that occupant worked the system .. which as a investor i was angry but as a eveyday citizen i couldnt gelp but to say ..hell ya.. you go.. its so disgusting what the banks got away with .. and still getting away with ..

I'm an agent and I solely work with investors looking in the Greater Tampa Bay Area.

So that way, if someone decides to sue, not only are we protected by the way we layered the businesses, but the impact on our overall portfolio becomes much less severe and is isolated to a single subsidiary. 

Then isolate those guys and call them first.

I will never build another up/down duplex, I just don't think it's possible to isolate the noise like you can with a side by side.
