If  The tax buyer has strictly complied with the Illinois property tax code, they can get possession about a month or two after the redemption period has expired.2.  

Are you mass mailing to zip codes, or targeting expired, FSBO, NOD, rentals and out of state owners?

Upon the expiration of the 3rd day the eviction may be filed.

When does the contract expire?

There does not appear to be a security deposit and the lease was a 6mo lease expiring in 2/16.The property isn't priced at gangbusters, cashflow is going to be less than $100.00 with Vac, Cap, Maint, PM, and Ins expenses included.  

You will also want to know the length of the leases in place and when they expire.

So if nobody has started tax foreclosure yet, the first lien is getting close to expiring worthless. 

(c) If, during the third or subsequent year of a lease, or during any renewal after the expiration of two years of tenancy, the landlord requires the one month's rent escrow provided herein, upon termination of the lease, or on surrender and acceptance of the leasehold premises, the escrow funds together with interest shall be returned to the tenant in accordance with sections 511.2 and 512.

In the final days before my extension expired, I stumbled across an advertisement on a community forum.  

In the event that I can not find another buyer to assign the contract to then I will honor my word, and get a HML to fund it so I can close on it before the contract expires.
