Wichita Falls Texas Tax Deed Sheriff's Sale Questions

[Marilyn Bayless]

I have an interest in two properties which I think are very desirable on Central Freeway in Wichita Falls Texas (account# 100283 and 100284).  The local school district plans to build a tech school in the area and so interest is keen.   I can see on the website called wichitatax dot com that these properties are being prepared for a sheriff's sale.  How long are properties advertised ?  How can I find out when the sale will take place ?
