Hi Wei, I tried a couple of avenues to try to answer your question without a result. When you bought the property the Title Company would have delivered a Tilte report and a Preliminary Title report. That is where you can find the answer for the question you have posted. You may also call that particular Title Co. and they can provide you with the info. Someone here may have the report...like you original agent ....who would have it. The records are to be kept for 3 years following the transaction.
