I also want to say that if you see this as a true passive investment, you'll be in for a surprise because it's anything but....usually.

So, the chances of someone trying to find the TRUE below market deal in their “spare time” is not great.  40 years ago you could.

My approach is to take a few minutes per quarter and make sure it is accurate by manually checking my true competition and adjustmenting prices accordingly. 

If you think the money will come you quick in anything you do you’re better off just dreaming about what you want and saving your money and work for someone else to make their dream come true.

Invelo is a true all-in-one solution for real estate investors, built with industry-proven best practices.

I am seeing more bureaucracy like inspections and fees, which I can understand because some people let their places become true hazards.I do agree what @John Underwood said and would consider lawyering up. 

Very true.

Assuming that's true, I would recommend looking for a replacement property (or properties - you can purchase multiple in the exchange) with value of at least $725K (selling price).  

I knew that was not true because I had paid $780 a couple months before on a property in the same area and also my realtor told me that her clients had been paying that lower rate.
