Estimating expenses in CoC Return calculation

[Paul Wolfson]

Hi all. 

I'm trying to analyze deals and am not sure what values to use for estimating expenses. 

@Scott Trench recently posted a great piece on his Instagram account, basically saying the "50% Rule" is misleading. Many just use 5% for maintenance and 5% for CapEx, which I suspect they picked up from watching the BiggerPockets webinars.

It would be silly to say that a SFH rents for $2000 per month, therefore needs $200 allocation, but same structure across town with rents of $4000 per month, needs $400 allocation.

Having said that, I wanted to know, for those with investing in SoCal, how much do you estimate vacancy, maintenance, and CapEx?
