Due diligence steps and concerns - looking for guidance.

[Witold C.]

Hello BP community.  I finally decided to make the leap and started looking at properties.  

In general, I am comfortable evaluating financials, but I am not sure how to do my due diligence.  

Specifically, I came across a property that was very interesting to me, but through sheer luck I found out that there may be a condemnation order on it.  (though a google search that came up with a new story.)

How do you do your due diligence?  How can I check if there are any city orders against a property, or outstanding liens?
