@Pearce G. The whole "messing with my turf" thing is just an expression. It's not literal. I think that most people read the first post a little too seriously and without the sarcastic frustration that was supposed to be expressed.
In all seriousness, I initiated a bidding war for three reasons, none of which are pure spite.
First, I need to gauge my competition and his or her knowledge of the market. Are they a newbie who is desperate for their first deal and willing to overbid? Are they completely ignorant to the market and willing to drive a price beyond what is profitable? Do they have disciplined limits and do they do research on each property prior to making a bid or will they just continue on aimlessly?
Second, There is a small pocket in there where we would have considered wholetailing the property ourselves. If we were forced to pay between $110-113k for the property, we would've taken it ourselves, hired a local cleanup crew since we're not located in the area, hired an agent and tried to list it for a profit. Wholetailing is not our preferred method, especially in a market such as this one, where hipsters are buying turnkey properties at a high price and flippers don't want to buy high because it's too risky. The hope with a wholetail in a market like this is that we can find a buyer who intends to occupy and who isn't afraid of doing work his or herself. Hipsters and millenials aren't as inclined to that approach for some reason.
Third, once it got bid beyond our wholetailing range I threw it to a flipper for a $500 finder's fee. I bid on his behalf because the seller and his daughter knew me. His limit was $125k.
When I got outbid again (to $130k), I said $135k partially out of spite and frustration and partially to see whether the competitor would dare to make another bid ($135k is not really profitable on this property). To my surprise, he did. $139k. That's where I drew the line.
