What is the best way to go about approaching the big apartment mega-complexes with this somewhat unusual situation considering they usually do things by the book.

Is it unusual to get extended terms (20-30yr?).

You have an unusually good PM, one who is placing your interests above their interest is getting another placement fee.  

The next time you enjoy filet mignon at the club, send word to thechef that it was excellently prepared, and when a tired salespersonshows you unusual courtesy, please mention it.Every minister, lecturer and public speaker knows thediscouragement of pouring himself or herself out to an audience andnot receiving a single ripple of appreciative comment.

Is it unusual for the seller to recommend one? 

I have had some , lets say unusual emails from people requesting information , people I dont know , never met , wanting proof of ownership , name of my loan  company , and other questions that were more inqusitive than the normal " are utilites included " and "do you allow pets".  

And I still had taxes, insurance, and repairs from damage from our severe storms in Sept 2013.I could also say that craps must be a winning game because twice I've started with $200 and walked away with $500.But I know good and well that these sort of exceptions to the averall average aren't unusual.  

I was wondering about that as well; 5 adults does sound like an unusual situation.

Hi All-     I'm under contract on an unusual REO.  

and now the big one....If I bring you a deal that meets your criteria, but you found out that I would be making an unusually large assignment fee, would that make you uncomfortable about going forward with the deal?
