Seems like a great deal, how do I know if I did it right?

[John Breen]

So, I am new to the BP world and the calculator. I watched the recent webinar with the live example (great help by the way) and I watched the YouTube video with Brandon doing one in Waco, TX (also great insight). I have essentially mirrored the process and all the numbers add up and come to be within the margins I am looking for. (400+ cash flow/month, CoC ROI of 8% before haggling price on property (target price gets it to 12%), little to no work needed) Additionally, it has established tenants on the property till 2021 and is recently renovated from inside out so it will be a buy and hold property.

To me, it all sounds to good to be true but I am also of the thought of why hasn't anyone else jumped on this property as it has been on the market for over 2 months which seems like a red flag in most occasions.  Any guidance/advice/tips would be greatly appreciated.
