He should have already explained this but, you need to talk to whoever handles the auction, I assume a trustee there.

You could buy the bank’s interest, then you’d be exactly where they are.....you’d have to file suit, which may or may not be successful, to have the property auctioned off, and split the proceeds accordingly.

Once the bidding is finished you immediately have to pay owed taxes via the bank account you provided to get into the auction. 

I'm planning to target off market (auction) properties and was thinking if I could only have someone look at the properties I'm interested in, send me photos and videos, and maybe even get an estimate on ARV or rehab costs, I could proceed.

B implies.Hint: go watch a probate auction before you decide to go into the business.

You don’t “foreclose” with an attorney, the tax collector sends it to a public tax deed auction.

Well we went to the duplex we won at auction.

You likely are needing to do a Partition action, which would send the property to auction with everyone splitting the proceeds, if you and the other owners can't come to an agreement.Agreed, you need a local attorney....you should have checked with before entering this.

A property I’m interested in buying is up for auction in about two weeks.

I find it hard to believe that the Tax claim bureau didn’t notify them about any of the 3 properties being going to tax sale auction.
