It was a Trustee Sale and never available on the open market. Looks like it sold for less than lot value. The owner had pulled much of their equity out in refinances over the years. Likely the buyer will be putting it back up for sale...so keep an eye on it. It won't be quite as low...but might still be a bargain price if the buyer is looking to sell it for more than he paid, but less than market value. That happens a lot.
My guess is even though it is assessed at $210,000 with $110,000 of that given to value of the structure, it might have sold as a tear down. If you would buy if for, I don't know, $80,000, you might want to send a "proposal to purchase" to the new owner before he puts money into it.
