Santino plays "Pat", the youngest of eight brothers (not counting his infant little brother) growing up in the 70's.

One property my brother owns is zoned R3 (in that city MF up to 3 units) however it has more than 3 units. 

I hear what your saying brother and agree that might be what's happening.

My coworker mentioned that his brother in law is trying to get rid of an apartment complex he inherited.

@Neel Jain , thanks brother.

Maybe I got lucky or maybe I'm recommending my brother-in-law.I'd rather give objective criteria that helps the individual screen whomever they decide to look at.

You might think that without money changing hands that it can't be binding as there's no "consideration" - but my attorney tells me that courts have held that the offer itself is a "thing of value", so the contract itself can be the consideration.It's unlikely that the unsophisticated FSBO will end up bludgeoning you with this, but if the brother-in-law turns out to be an attorney, it could go sideways.Strategically, I'd get face to face with him. 

Hope this helps and best of luck to you brother!

My brothers and I have already started investing in the midwest. 

I began doing 'make ready' single family homes for my brother's company at 14.
