There is nothing more permanent than a temporary gov program, and god knows they aren't going to downsize. 

It's an interesting subject, one I've broached with other agents as frequently as I can; consensus among those who seem less emotional about the market is that Boston is a different city then it was in 08; albeit dramatically much more financially stable.

TREC does have buyer and seller temporary leases.

This means you need to analyze this deal in an excel sheet and make sure the property makes sense if you had no emotional attachment to the situation. 

The property is the temporary resting place for your assets. 

This property is a bit different being part of an estate of someone that is deceased, but that may have been advantageous due to the fact that the people now responsible for the debt may not have had an emotional connection to the property. 

I realize each of them comes with various emotional/time/effort tradeoffs, so I was really wondering if any of the wise folks on Bigger Pockets might be able to help me form a more clear financial view of the various options?

Is my logic valid or am I starting to get too emotionally attached to this property?

If you don't get a hold of your emotions you will tend to do the exact opposite as what you should do.  

Perhaps I could rent it as a small business incubator or temporary space?
