TEXAS TAX DEED INVESTORS- what's the 1 thing you wish somebody told you before your 1st purchase?

[Sundai S.]

Hello all,  I have been researching the tax sale auction process for a few months, researched each propriety on this months list.  I have taken an online class and have access to online GIS, CAD, and county clerk records.   

So now I'm seeking the wisdom that can only come from real world experience.  

Please leave a comment concerning, something you wish you knew, or had to learn 'the hard way' or a bit of advice about clearing title clouds, dealing w/ residents, anything that the folks trying to sell you their book or class don't tell you.  

Thanks in advance!
