If the relationship is civil, I recommend you start by having a conversation that explains that you will be proceeding with an eviction (research the eviction process) and that an eviction will result in it being very difficult for the tenant to rent a nice home for years.  

If you want your name on the deed, that may be difficult. 

My situation is difficult.

As I attempt to buy my first duplex/triplex/quadplex, and seeing as I currently have no frame of reference, I'm having a difficult time knowing if my expense estimates are accurate. 

So when you state some jurisdictions have made it more difficult, can you elaborate more specifically?

i travel 70% of the time (in flight now) so it can be difficult to commit

Makes it difficult to get accurate value because of small sample size.Some infoLocation, affluent west shore suburb of Harrisburg, low crime,  family oriented neighborhoodRanch style, 2400 Square Feet total, everything updated by hvac system (works fine)Each unit has 2 bed 1.5 bath, one is 1400 sq other is 1000Rent is 1450 one side, 1500 the other, renters pay all utilitiesInsurance, maintenance, and yard upkeep total 3000 a yearGood renter clientele, most are doctors or nurses, close local hospitalsBoth have separate driveway and yard  Located in well of neighboorhood in low tax hampden township, taxes are 3500 a yearThe duplex was grandfathered, out of the 400+ houses in the  development, there are only 5 multifamilies. 4 houses down the street sold for between 380-400k in the last 4 months.

In this case, I would imagine that it might be difficult to prove that the Seller meant harm, or falsely reported info.

If there's an extra house on the property, it will be hard to find something similar and it makes for a very difficult and expensive appraisal that may or may not work for a lender.

It was difficult to plan when we needed to be there for the remodel.
