My bet is that he won't voluntarily leave and you'll be forced to evict him.

(Click on the "learn" tab above) One of the more interesting points he made was that on a multi-family, you can force appreciation.

If you're going the forced appreciation route you aren't getting your 30k back.

You may be forced to use a non-traditional lender (ie: not a major bank).  

You’d likely have to get involved in task force initiatives, block clubs, community groups, get police involvement etc.  

Without going into detail, we were forced to "mutually terminate" our agreement after it took him 12 months to get the foundation and utilities in.We purchased our land in October 2016 outright for $107000 and got a construction loan for $320000 in May 2017.

Although my Broker didn't do everything correct by standing behind its agent, and it is seriously in dereliction of asserting its rights to include its agent in negotiation, Opcity's fault lies in bait and switch the agents coming in by its website, and not showing the referral fee on the Opcity-Agent Agreement, and forcefully demanding 35% based on a referral fee schedule not suitable for NYC market. 

So I am forced to look elsewhere for a deal that cashflows.

There's a great book that BP puts out for estimating rehab costs, but it would be awesome to walk through a prospective property with a touchpad that forces me to check all the important bits and record photos, and then spits out an estimate of the rehab costs in a similar way that that book does. 

I agree with @John Underwood in today's climate I would be very cautious in forcing a showing.
