Hello BP Fam!

There is a lot of land here in SWFL that is parceled out and there seem to multiple avenues to purchase these lots at discount. I'd like to buy them at discount and market them to finance or potentially even build. I have had some luck with mailing letters, but I've noticed that I can pick them up at tax deed sales at discount as well. Of course there may be liens or otherwise debt on the property that may cause issues. My question is:

Is paying title search on these properties enough to verify that they will be okay to bid on? What exactly are they doing when they search anyway, isn't everything online now? I wouldn't mind going down to the county if need be and checking files. Also, I would probably pay for title insurance as well, how does that work when I'm buying the deed from the county and/or the certificate holders? Thanks for any and all help and best of luck with everything you do!
