Does anyone have any ideas on how to minimize that tax liability and still continue with my original intent, or is my only option a 1031 (I'm aware of DST but don't see that as a great option).  

Thanks @Michael Baum@John Underwood , will consider both options , definitely the extension is nice revenue

This will help direct your search to the right areas, property types and price point.If you're purchasing all-cash, skip that step.Depending on your goal and preferred timeline for closing, the majority of your time should be spent searching for and analyzing deals.Searching: Look at public listing sites; connect with an investor friendly agent and choose 1 to work with who can search MLS and off-market inventory; for additional off-market options, consider growing your own database of wholesalers and homeowners Analyzing: Your agent can send comps and you can also search public listing sites for sold homes.

Waylon- To have the largest buyer pool, my opinion is to price and market the home as furnishings or turnkey options are negotiable.Since this home is flexible in its use - let the market participants decide which option works best rather than defining it for them. 

Reach out to @Dmitriy Fomichenko who has the best options out there.Good Investing...

I completely understand your concern about potential vacancy issues, especially when it seems like there are so many rental options available in the Philadelphia area.However, not all areas are created equal when it comes to rental demand.

If you're in that situation, ensure you follow proper procedure and proceed with that option in conjunction with your eviction process to have redundancy.

Do you have the option to move back into it for another year? 

I actually have two options for this property: 1) Rent out the existing 25 storage units AND rent out the building plus add the 25 additional units out of pocket.OR 2) Rent out the existing 25 storage units and added the 25 additional units out of pocket to rent them out BUT keep the metal building for my GC business to where we have offices and storage for building materials.

Works really well (I used the CSV option) - but the Stessa import tool does not bring in the GUEST SERVICE FEE from the Airbnb transaction.
