Not today, that same attorney is much more aware of issues beyond the scope of their specialty and can obtain information in a few minutes as to the steps to cure the problem for their client, like taking you to a judicial foreclosure regardless of any equity amount, as it is nothing more than a suit to be filed to get you there.That's why I said check locally, I'd say most attorneys will opt for the note and deed of trust, buying or selling. :)

Some defects can be cured, some can not.

That will cure you of swinging a hammer pretty fast.Your time is better spent finding opportunities and making offers.
