Also, do I bring a locksmith with me to open the place up?

Lock smith entered common area.

As long as all tenants are staying in place, I do not see the point in rekeying.

Just get an eviction company to come take the person's stuff out to the curb, and either change the locks yourself or have a locksmith do it as soon as they are out. 

Let them pay a locksmith to fix the door knob.

so we finally get possession of our duplex we won at auction. legally, the company we went through to get deed said, we cannot talk to anyone or enter the property until the 30 day eviction is up. so this Saturday is the day the we willl go over and get a locksmith to enter.my wife found out from neighbor there is a 20 year long tenant upstairs but the owner lived in lower unit.

The locksmith is coming Monday, I got a verbal from the bank to accept less than full amount on the lates and penalties and might be able to get this place nailed down by mid-March or so.

Forgot the kickback from the locksmith.

And if they don't have any keys to send, then you will need a locksmith - but permission of owner must be obtained ahead of time.

It will be re-assigned to another broker/agent on their list.Listing residential REO ship sailed long ago.Many of my broker friends have stopped listing for banks and work on the buy side more as they pick up a bonus.On the REO side you get hit with BS certifications from asset companies wanting hundreds of dollars a year to be a MEMBER and POSSIBLY land a listing.When you do it's a POC (piece of crap) and you have to outlay a money with rekey and trashout,cash for keys etc. in some cases and wait for the money to be paid back to you.If you have a buyer for the property try to deal with FNMA.If you are just after a listing you need to go with a big reo brokerage already established and be a buyers broker.As local and regional banks have told me they get calls almost everyday from agents wanting to list their REO's.I am more valuable as I focus on the commercial side so they don't get as many of those specialized types.If you are the broker you can go to the local banks and offer to do it cheaper for volume and land business that way.Thanks
