So I found a rental property that I really like on the south side of Chicago but I need some help with Analysis.  Its a two Unit building with a full unfinished walk out basement that could eventually be converted to a 1 bedroom unit. According to the bigger pockets analysis tool, the way it is currently, my monthly cashflow would be $631. My cash on Cash RoI is 240.74% since I'm purchasing it with 3.5% down payment an my purchase Cap rate would be 14.55%. Is this a good deal? I was hoping for more than $631 per month but if this is a good deal, i'll be okay. I'm new to this so I just need to get oriented to what a good deal is.
