From a selling standpoint there are 2 big concerns:1. disclose - you know there is an unpermitted room and/or any other problems (you said something about electricial).  2. the buyers loan/lender. 

An appraiser is obviously going to inspect the house and our concern is that we then would not be able to finance as a duplex, not to mention the added property taxes.Listening to Brandon Turner's The Book on Investing in Real Estate with No and Low Money Down, we thought maybe this property would be a perfect candidate for seller financing?

Most management companies I’ve found will allow you out of your contract when your tenant leaves.

We also host a breakfast network event on the morning of the 3rd Thursday at the Sunrise Grill from 6:15 AM to whenever folks leave. 

The tenant's rent will cover most of the mortgage but not all leaving me coming out of pocket about 400$.

It's just common sense, but sometimes you just need to read it.http://www.littlethingsmatter.com/blog/2010/02/17/...https://sajigroup.com/law-of-magnetism/I'll leave you with these words from John Maxwell (I believe): What determines if you attract people with your desired qualities is not what you want, it is who you are, that is how the Law of Magnetism works.

I think perhaps the biggest concern is how you plan to finance your presumable future purchases.

I'm leaving behind my parents, sister, BIL, and little nephews.

It would be silly to get into a bidding war with someone else who just wants to leave the trees in place like you do.

Then, I leave the rest to an inspector.
