Thumb rule to determine rental deal feasibility?

[Siddharth Parekh]

Hello

Is there a thumb rule to determine if a rental apartment or home deal is good? What should be considered a good return % wise, let's say in Houston, TX or Minneapolis, MN or Chicago, IL. 

Thanks

At this point in the cycle, you're not going to find a 1% deal in Minneapolis.
