https://cmsheetspro.etsy.comI have some Construction Management and Material Takeoff & Cost Estimating spreadsheets that could be helpful.

I gave the agents money for materials upfront and supplemented that when we decided spend more on flooring.

I did not buy any construction materials though like tile and flooring but I know it's a big discount

So unless you buy move-in ready houses prepare to work VERY hard, even if you have a lot of cash to burn the growing pains of time management, contractors,buying materials, getting out of the office to make a some quick calls, taking some days off, you can kiss your social life goodbye, so stress/hassle?

I'd recommend tile or some other hardy material right in the entry way.

So first, there are fire retardant requirements for materials to prevent fire from spreading.

I do agree that material things can, and will keep people running the rat race.  

My contractor says he charges $1000 a day for a crew of three plus materials of my picking.

When you are getting bids, are you sure the quality of materials being used is the same?

$185 doesn't cover much of anything as far as materials for maintenance and repairs let alone hiring any kind of assistance when you need it.
