Tax Deed Sale and Title Search

[Misty Quaintance]

I've been to a few tax sales now and there have been 100's of properties. Out of these I'm usually interested in 20-50 properties. Do you realistically do a title search on 20-50 properties before bidding understanding you may only pick up a couple? I'm just wondering how most people handle this process as it seems like it could get pricey to do a title search on all the properties I may or may not get.
