Estimating odd things

[Kim Handelman]

Hi Rehabbers,

I have a wholesale deal that I'm working on and don't know how to estimate some things. First off the entire house needs new flooring. High end neighborhood so Hardwood throughout except bedrooms. It's a 3,000 sq ft house. How much for hardwood and carpet do I calculate per sq ft? I'm in CT and I posted on our local forum with no response. 

Second, this house is the ugliest brown I've ever seen. How much to paint exterior? Is there a sq ft price on that too? and the roof is in decent shape but really stained. Can you power wash a roof? THanks,
