Rehab estimates on my first property

[Josh Baker]

I will be starting a remodel of a duplex next week and I've put together a spreadsheet of estimated costs and durations for the various subtasks.  The home is 2000 sqft. and has an additional 500 sqft. partially finished basement.  I'll be working on it with one other person.  I'm estimating about $74k in costs and 108 eight hour days to complete.  That is around $30 per sq. ft.  

Looking for feedback on my estimates.  Feel free to tell me they are way too high lol!  The order column is the order in which we plan on completing the tasks.
