Do you have specific houses in mind?
Many of the abandoned houses and buildings in Cuyahoga will go to auction, but not the sheriff's sale. The board of revisions will auction the property sometime in Autumn. It will be a three day auction at a convention center. The forfeiture auction, it's something to keep in mind if you can't find the owners.
I'm watching quite a few abandoned properties. The owners are deceased with no known heirs. I'll try my hand at the auction.
Here is a brief run down on how to find out if the property will be at the forfeiture auction.
If you get the property address, go to the county auditor site and search it. Find the eight digit parcel number. Write it down. Go to the county clerk of courts online docket and select foreclosure search. Put the eight digit parcel number into the search criteria and see if a "BR" case comes up. it will look like BR-19-916503. Click on the link and explore the docket. If the people are alive, the address they live at currently might be in listed under the service entries.
Or, use Spokeo or Intelius, or some other site like them. If they are a live, you should be able to find them, but getting them to have a conversation with you might be a bigger challenge.
You can message me, and I'll do it.
good luck
