Ways to roughly estimate rehab?

[Joshua Krilov]

I came across this video on youtube with a chart to quickly determine a rough estimate for repairs.  

I'm wondering if anyone can give me a similar chart with LA prices? I am aware that the best way to get an estimate is to do a walkthrough with a contractor but I am looking for a way to guesstimate. Or if you have a better method to do rough estimates, I'm all ears.
