My address is updated on the auditor's website, so there is no problem there.Anyone has any idea what is going on? 

Begin with the county auditor site. 

Just an idea to show any potential auditor that you haven’t gone back and changed all of the records - and if you did you can explain when and why.  

It will be adjusted under audit or examination with substantial understatement penalties (because it's a frivolous tax position), and the courts will agree with the Service here.Third, if your LLC taxed as an S Corp owns the property, you ruin your Sec 121 exclusion, and probably your homestead status for property taxes.Please consult a competent tax advisor.

If you look it up on the auditor site, that transfer was 5 total parcels,  30-36 eureka is only one of the 5 that transferred together for 378k 

Also check the auditor site and make sure it was just a single property transaction.

The auditors website lists the property in tax foreclosure with the original owner (deceased) listed.

I started by pulling lists off of the Franklin County auditor's website and skip tracing them.

The Auditor didn't have that resident in as a unit.

Here is an excerpt from that thread (page 5) that I think will help you:I have had some inquiries on the format of letter that I used to make contact with owners of multifamily properties that I found on the auditors site.
