Our goal is to establish a structure where the property owner can secure financing based on the long-term lease with the operational company.Any advice or insights from those who have navigated similar situations would be greatly appreciated!

I would encourage the use of a warranty deed to the situation that @Steve Vaughan mentioned above.

The best properties are not always the lowest price but the ones that make the most money for your situation. 

Plus MANY MANY more problematic situations that come up daily.

I have a good cash flowing portfolio that has appreciated extremely well In the last 10 years, it’s a small college town off the radar,   and I know it’s a unicorn situation to find deals that are in markets set for great appreciation, and have solid cash flow, but I know there’s more out there! 

And you are taxed on it.the easy answer to your situation is to complete the full 1031 exchange. 

If anyone has been in a similar situation or has actionable advice, I’d greatly appreciate it!

There are situations where it is more beneficial to end the current lease and start a new one (ability to change lease terms, rent amount etc), and there are situations where it makes more sense to just do an addendum.

The terms and costs will depend on the property, your personal situation, the location, etc.

One bad situation can harm all the properties.
