Rehab Costs in Portland

Hi Guys and Gals,

I'm a wholesaler and new to Portland. I was wondering if there is a rule of thumb formula I can use to quickly estimate repair costs in this area, for example it costs a house flipper $X / sq ft to rehab a house, that would cover kitchens ,bathrooms, floors, paint, etc, of course barring any major repairs such as roof, foundation, etc. 

Thank you,

Scott
