The condo never would have made sense to purchase purely as an investment but once I owned it for personal reasons, it also did not make sense, to me, to sell it.So with all of that being said, I'll be the contrarian. 

Just pure synergistic client relationships where you work well together and are in it for the long haul.   

I have to get to the point of feeling like I'm nagging to get even a purely informational response from my primary residence hoa. 

Purely from an investment perspective I would be concerned with the almost infinite amount of competition that exist.

In all seriousness, I initiated a bidding war for three reasons, none of which are pure spite. 

In Worcester we have a pure monthly cashflow of about $900 a month, $300 per unit.

This is PURE cashflow for them.

Pure and simple.

I figured the listing price would be based on comps (like when I bought it), but I was unsure because it is a pure investment property now and I thought maybe it would attract a commercial buyer (where NOI is king).

If you are a pure squatter, it takes 20 years of exclusive and continuous possession.
