Cost Estimation for Rehab

[Jonathan Orr]

I am looking to rehab a home (purely cosmetic) in Los Angeles County.  I have been doing a lot of research about costs and I will be getting bids from contractors. It will new kitchen, floors, redo bathroom from head to toe, maybe new plumbing if needed.

However I am really trying to find a estimated cost sheet so I can develop better estimates when looking at properties prior to getting bids from contractors.  Is there a software or templates that can give me general costs (specifically for CA) for rehabs (pricing for flooring, cabinets, etc...) and/or if there was a thing showing typical markup that contractors use so I can gather my own pricing and pad it with markups.

Any suggestions? Thank you in advance
