all mailing address of a foreclosure

[Gerald R.]

I purchased 2 properties at the Wayne county auction and both are multi units.  Is there a way to find all of the mailing address associated with a given parcel number?  I'd like to mail a letter to current residents letting them know that i'm the new owner and willing to honor the their current lease given that they mail me a copy and setup date and time for inspection, find out if they want to stay and what rent if any they are paying.  I know that I have to wait until I get the deed to prove ownership but that can take up to 30 more days and I'd like to start the conversation now and i'm not attempting to collect any rent.  Any help suggestions would be great.  

Also Anyone have experience with doing quiet title on a foreclosure to get a warrenty deed?

Thanks,

Gerald
