It will be difficult to find out which person at the bank to speak with and if it has been asigned to an asset manager or not, etc. You can try, but if there is indeed a lawsuit pending, they won't be able to sell it anyways.
Best of luck
I have to agree with the previous answers that something is going on with the property. In Illinois, there is a 30 day right of redemption after a property goes to auction, so that could be the delay. After a property goes back to the bank at auction, there is no set time frame as to when it will come back on the market for sale. It could be a month and it could be a year.
If you want to send me a message with the address of the property, I can do some additional research to see what might be happening.
Until the issues around this property are resolved, I doubt anyone will be buying it anytime soon. The previous owner has filed a suit to hope to redeem the property. This could take months or years depending on their willingness to fight it on.
That a family member may be helping them isn't surprising. I have helped many family members buy & sell homes.
I would suggest you find another home. If you check back on it from time to time, you may find it available, but if you focus on this one only you'll miss a lot of other great homes.
