Properties selling three times in three months, what is going on?

[Eric Wallace]

While researching properties on the county assessor tax websites I often come across properties that have sold in very short periods of time for substantial differences and it appears the buyer is often a trust and the seller may be the owner of the trust.   Example: I recently came across a property that was purchased on 6/13/13 for $75,516 then sold on 6/26/13 for $29,300 then sold again to a trust on 7/16/13 for $42,700.  Is what I am seeing some sort of strategy for pulling income or tax benefits?   Just curious if anyone has an idea.
