He then went through a lot of transient student tenants. 5 years later Burger King bought the corner lot & all three adjacent homes.

You can probably find a CPA that is willing to claim they were bought as investments, but flipping a house is as much investing as flipping a burger is: they both build money so that you can invest.

I have extensive experience with this as I was in the restaurant industry for over 10 years before getting into commercial real estate.By checking the books you can see sales patterns for the type of product they sale.You can see over the past few years if a majority of the sales are seasonal and then if that part of the year has already occurred.If the strong sales are still ahead of them in the coming months they can have a good chance of catching up.If they have already had historically the strong sales months of the year then they are in really bad shape.Also it's important to note their sales volume over the years versus new competition in the area.If they have a burger joint and within a 2 mile radius 4 more burger joints have opened up and sales are declining along with profit margins then they are in trouble.Does your current tenant need all the space they have??

Books like Who Moved My Cheese by Spencer Johnson, The Cashflow Quadrant by Robert Kiyosaki, and then business books like E-Myth by Michael Gerber.

However if you're in the hood where evictions and non payment of rent are an everyday occurrence that guaranteed government cheese is mighty nice.
