How to determine vacant vs abandoned?

[Tasha Pams]

I recently purchased a tax deed in Jefferson county and wanted to know how to determine if a property is considered to be vacant or abandoned. Based on what I could see through the windows, there is some furniture in the house but I don't  think the utilities are turned on. I'm assuming it's vacant but it could be a second home.

Also, do I keep the furniture assuming the taxpayer wants to redeem or trash it? Could storage fees be included in redemption as well?

Thanks in advance!
