Security Deposit

I recently moved out of my place 6/30/2009 - an apartment in Chicago, IL in 3 dwelling unit building owned by the landlord (does not occupy the building) making it subject to RLTO and its provisions.

1. On 7/28/2009 he sent certified mail of a listing of estimated charges from his property management company - keep in mind our lease was signed with him personally. He also sent check for our deposit, which is the difference between our total security deposit less his charges - no calculation of interest included or taken into consideration

2. He provides pictures on 8/4/2009 which are no more than reasonable wear and tear of the status of the condition of our apartment subsequent to us moving out

3. On 9/2/2009 he sends certified mail - ONE INVOICE, with no proof of payment and no receipts to substantiate the charges from some carprentry company, which coincidentally shares the same address and fax number as his property management company. Keep in mind this is past the required 30 day time period from the date he provides listing of estimated charges. This carprentry company does ALL repairs (dumpster removal for personal effects done to the apartment, carpet cleaning, replacing specially ordered tile, furnishing/rebuffing all hardwood floors, patching drywall/painting)

Thoughts on what I should do?

It appears,that the landlord complied with 5-12-080 Security Deposits, Sub-section (d), (1) and (2). If you have a question about the interest thereon, ask the landlord, he should reply to your written inquiries.
