Does my Attorney even know!? Illinois Subject-to Legality

[Landon Thomas]

In Illinois, are Sub2 agreements required to reported to the lender? I have a property under contract with a distressed owner. I sourced it off MLS, listed by an agent I worked with before. I made the offer 2nd day on the market. To which it was accepted 2 days later. I made a cash offer and I am utilizing approx 50% of my own capital (real cash + Heloc) + 50% private money. I still need time to negotiate the private and I don't want to rush the private money (first time working with them). We had a 60 day closing for the seller to find a downsized rental for himself. He found his rental less than a week after the accepted offer. The seller is now requested a 30 day closing. I asked my attorney to make mention of Sub to offer to the seller to see if it was something that would interest them for quicker close. He said he would not because it would be reported to the lender and likely have the loan called. I don't think my attorney knows for sure what he is saying, but I wanted to share my novice story to see what else I might be missing. Thanks in advance.
