Rehab estimating

[Kyle Godbout]

Hi there. 

Since I'm going to be getting into buy and hold real estate investing, I thought I would tap into the incredible knowledge base that is the Biggerpockets forum. 

I was wondering what rehab renovation costs checklist, spreadsheet, or software you are using (if you use them that is) to estimate rehab costs? This can be free or paid. I have a general knowledge of this, but am looking to learn more. 

Thanks!
