FSBO and 1031 Exchange in Illinois

[Jim Bryant]

So I'm trying to sell one of my rental properties to trade up to a multi-family home.  

There is no problem with finding a buyer, my renter wants to buy it for my asking price.

Since I already have a buyer, I don't think I should use an agent.  So what will I need to make this sale all legal-beagle?  Some people are talking about escrow or title companies and others about getting a lawyer.

In addition, since I want to do a 1031 exchange, I guess I need to find a QI.   Also for the purposes of my 1031 exchange I am looking at more expensive properties than the sale price of my home and at the time of the sale I own the property outright.  I read something about needing the amount of debt to be greater on the new property, but since I own the property I am selling outright, I would imagine it doesn't apply. 

This all seems very complex, does anyone have experience with this in Illinois?
