I'm also new to real estate here in the US as I'm french. I'm also very interested in starting in the nich of the deliquent property taxes. I do not know where are you located but I live in Miami, FL.
I do know very well how to use data on excel spreadsheet. If I can help you. I will.
The first step is to figure what properties they represent. My guess is they are using property tax identifier number. You need to find a way to get the addresses for those numbers. I would ask at the place you got the list.
You state may have owner information on line. Go to the state website and look them up. Or pay someone to do it for you.
To get addresses if you have permanent property ID number is easy: go to your county auditor site and type in the number. You'll see the name of the owner, address and whole nine yards .....but you understand that there might be tax lien certificates, so if you make a deal with the owner, factor these in: they attached to the property and are first in line to get their money.
If you go to Sheriff sale of your county and see tax sales, you'll notice that amounts are small but if tax debt is higher than the sale amount, you'll have to pay the difference
130 pages?! My advice is to hire a Virtual Assistant to help you clean up the list once you get the addresses. You can hire a decent VA starting around $2 an hour on Upwork.com
some very useful information here ;)
@Janice Delantes more information is needed and it would depend on the state. It doesn't sound like MD so I cant' give you specifics. We do have tax lien and deed experts here from many different states.
From this wording
it is owned involuntary by county by default and they have instructions about purchasing these properties by bidding
I suspect it means that the county is selling a tax deed. These are normally sold at auctions. However it sounds like it could be a case of they had an auction with no bidder so the deed remains with the county and is available "over the counter" or post sale deed.
if I am correct the owner has already lost the property. However some states have a right of redemption and the owner may have a right to redeem the tax deed and get their property back. In this latter case you may be able to work through the owner. In the former case buy from the county.
Tax sale law is quite complex and varies greatly from state to state and even county to county in some areas.
What state are you in?
