Either of you producing tax records/assessments, comps for the area, Zillow estimates (pause for laughter), etc?

Granny's Happy House; Laughter Lane; Sunnyside Up; Golden Gardens... paint a sign for it and carry the theme, a mission statement... 

and just to be clear, this is not a serious reply, just trying to create some laughter. 

When i explained this to my colleagues their initial reaction was laughter.

Irrational explanations should be met with contained laughter and an eviction notice.  

I'm afraid if someone asked me that, I would burst out in laughter!

I hope your holiday is full of love and laughter.   

All of these epic shifts, first meet with total disregard and laughter UNTIL they are hitting on beast-size. 

. - I didn't share my honest thoughts to entice laughter. 

This must be taking a toll to on yours and her relationship.This is why I never, ever do business with family or friends.When things go downhill, now you have to deal with seeing them at company holiday dinners, ugghhhh.I am not familiar with the NY landlord-tenant laws but know that, should this be processed as an eviction, what you are doing currently whether or not it shows up in court is not right and legally could work against you.Trust me, I really do empathize with you and your situation and it seems like this Brother in Law is really taking advantage of you, but don’t correct this wrong with another.Follow the legal process to get him out, talk to your wife to see if she can intervene at all, but it seems he may not listen to her either and just does not care.So my laughter is because I cannot for the life of me see how someone can think that this kind of behavior is right to do to anyone, leave alone your family.This man/boy should be ashamed of himself for putting you and your wife/his sister through this mess.After this, I suggest you be very careful about inviting family over for those extended stays that never seem to end.
