To wit, people might find this thread and exchange for years to come (I am cognizant of that future audience as I write this).

If you opened the exchange with the intent to hold the property for investment, and then in the future circumstance changed which caused you to reconsider the use of the replacement property and convert it to personal use, then a period of time less than two years might be reasonable.  

The electrical panel is original, so an upgrade might be needed in the future. 

We are looking to building some fourplexes in the near future in the area - when you say expand your portfolio - what are you looking for ?

Quote from @Rose White: When is the best time to ask your new / possible future tenant for a background check?

But my suggestion for future listings.Look at days on market in the area that you are going to list.

As for foreclosure, yes, the debt might go away, but it would wreck your credit and make it tough to borrow in the future, so that’s not a great fallback.

I would recommend looking at a loan with a short prepayment penalty if looking to get cash out, that way you can refinance again if rates drop again in the near future. 

If not, should I sell stock that I have that has capital gains that would be due on it and offset that?

I'm not sure I would get to cute trying to squeeze every time out of it now with a lease that might cause you issues in the future, but the scenario you describe is common and probably smart.
