I would also encourage you to hire an inspector for the duplex and have them give it a complete once-over.

Those are always encouraging. 

How do I encourage them (peacefully) to move out?

Just wanted to hop on encourage you to network here on BP!

Therefore it is strongly encouraged to make sure you do the title search and, as best as you legally can, inspect the property so that you can make some assumptions about its condition before placing your bid. 

I'd encourage you to take a look.https://www.biggerpockets.com/rei/self-directed-ira-real-estate/

Over time the individual sections shift , develop gaps and leaks and that encourages root growth. 

If you haven't already done so, I encourage you to run the BP cash flow calculators on some east side properties with taxes plugged in -- then run the numbers on a similar property in St.

I suppose we could all cheer you on and give you advice on how to "10x" your goals and flip 20 houses this year and purchase 30 investment properties, but that's like encouraging someone to jump off a 30-foot diving board after watching them belly-flop in a kiddy pool.You have one rental that has fallen apart and eaten up your cash.

I’m definitely not saying you shouldn’t go that route, I’d just encourage you to be very honest with yourself about what you want to achieve.
