@James W.
To your question
That makes it even more complicated if municipality charges wont appear on title search.
I wonder now, in a "traditional sale", how does the Title search company determine the Municipality liens and encumbrances - and clear the title for sale?
When I want to understand if a municipal lien exists against a property I search and find them at the courthouse. That is straight forward.
That being said, liens recorded at the courthouse does not necessarily tell the whole story. Sometimes these municipal entities have not gotten to the recording phase. Read my post "Burned by foreclosure" link to post. The best thing to do is call local departments which could have an interest in the house such as water and sewer. It has been my experience these folks have the latest bill and can pull up any recorded liens. You may find not all of these folks are that helpful and some may want info requests in writing. IMO is always pays to be nice, respectful and to always start the conversation out with (who you are, what your doing and then what you want).
I am dumbfounded by the statement that title searches conducted prior to a sale do not reveal all outstanding bill/liens/tax/whatever. That is what they do. That is what you pay them for. Maybe I just misread. Whatever.
On a last note, municipal liens is just a small piece if the overall puzzle and really one of the easier aspects of the process. Not sure this is the case but, if you want to start getting into title searches get some books on the subject. Make some friends at the courthouse who do this for a living, or hire an attorney to sit down with you. Never assume the folks who work for the county have any clue, many of them have no clue simply because it is not their job to.
Hope this help.
