Looking Up An Owner’s Contact Information

[Elizabeth Zielinski]

Hello! I hope everyone is staying safe and healthy.

There's a house on my street that's been vacant for a few months. It's got a few city tags on the window, and I came home not too long ago and there was a foreclosure notice taped to the front door. It looks like the owner hasn't paid taxes in a while. Seeing a potential opportunity, I found the owner on MLS. The only issue is that the phone number and address listed both with the city and on MLS are invalid. The phone number is to a man who had no idea what I was talking about (owner is listed as a woman), and I went to the listed mailing address (different city than the property location), but the people who lived there weren't the owners either.

I don’t know what else to do. Any ideas on how to hunt down the owner? Thanks in advance.
