California Texas Florida deed foreclosures Trustee tax auction

Hi.I want to attend some property’s tax auctions ,but I’m scared of liens that they may not wash in the auction sale. The research it’s time and cost consuming,and a lot of property’s can be redeem , right before the auction.If you pay for a title search on so many properties ,that cost can go up really fast.I’m trying to find a different way other then a title search or county records (like an online website )more cost effective and time efficient to do those investigations.Any suggestions are much appreciated
