I understand that a gas burning appliance in a bedroom could be a potential safety hazard however from what I have read, this seems to be common thing in Chicago and I couldn't find anywhere that this is a direct code violation for the city.My question is, is this something that I can get by with having a CO detector placed in the bedroom?

All those big shots on flyers, buses, benches, post boards etc.. burn 25% of their commission. 

Most class D landlords I know get burned out pretty quick. 

Also that they would never burn anyone given the fact that they want current investors to feel secure if they invest in the new program.

As far as deal making was concerned: A burned house that I found while driving a neighborhood I was interested in.

As for security, she burned that for the June month that she did not pay me for . . she insisted that there are and won't be any damage, which I doubt.  

Residential agents do fadeout more quickly and commercial is more specialized.Discount companies have been funded hoping to be the next big thing and they last a few years and then go out of business or contract.I have seen tons of them churn and burn over the years.

Now, to answer the OP's question; If I am playing with some other person's money, I would focus 100% of my time and energy on burning and turning that cash.

Obviously do this carefully without having them burn the place down.Option 2 would be to sit down with them and to gauge their financial status and their level of merit as good tenants.
