Tax Deed, Austin Texas, priority on the listed property

[Michelle Oliveira]

Hi, I'd like to know more details in how to research properties for Tax Deed in Austin, lands or property with homestead already. I read the creditors and IRS take priority over tax deed holders in case where the original owner of the listed property declare bankruptcy. 

1 - Which department in the county should I go to clarify all this information and previous searches? 

2 - I wonder in cases like that, why will this property go for a open foreclosure if the IRS or creditors have priority on it? 

3 - If I buy a property and the creditor want to keep it what can happen? 

Thank you.
