Short Sales and liens

At first I thought liens against a short sale property was a good thing (leverage with the lender) but when working the numbers - it takes from the net to the lender - so myself and title were researching the liens and having them removed if erroneous (100% have been) I had one for 100k that was erroneous and title was amended. Now I’m at the point where I don’t think we should be clearing title for the lender so if they don’t approve the short sale or we don’t close - now they have a clear title to take to REO. I know they have to do a title search anyway but when there are 3,4, 5 liens on a property - and we have them removed - we’ve saved them some time. So now I’m torn. Do we research and clear title as needed or leave it there until after “short sale approval” and remove accordingly?
