Once I have the figures, I do my own visual inspection of the property that sold for that price.

You'll soon began to visualize the difference and the effects of changing one variable in the equation.

These houses are purchased based on pictures they have been provided, not based on their own, or a third party's visual inspection.

If you guys could get it to the point where we could sort our colleagues by a visual map that would be great. 

Visually check roof. 

@Mindy Jensen, thanks for the visual guides.

I don't know the market in CA, but in Baltimore, I would pass on that deal since it's not too hard here to beat the 2% rule.Definitely take advantage of the Rental Calculator here to analyze the deals so you can easily visualize the tweaks in the math (increase in rent, lower purchase price, self-manage etc)

If you're just doing basic residential drawings and 3D visualization, sketchup might work for you.

That would give it a visually bigger look.

I hope this helps someone new visualize what this process may look like!
