A GC will usually charge you about the same price for labor as the cost of the supplies.

We threw out much of our stuff, furniture, beds, anything porous.

We allowed our contractor to use our store credit card to buy supplies to rehab our house.

You'll need to check the roof, the siding, supply line pipes and drain pipes, gutters, faschia boards for rot, windows for rot, etc. 

I called the local fire department and they said that I don't have a legal obligation to supply these items.

She suggested I have all the independent contractors supply me with a social, TIN # or EIN # in order to submit a 1099-MISC to the IRS at the end of the year and pay them by certified check.

There will be expenses for books and miles and office supplies, etc. etc etc.

You only needed a pinch, so luckily we only needed to order a tin or two at a time, but I still remember pulling my hair out each week as I'd check on the saffron supply and sure enough, one tin did disappear at one point, causing me to lock the extra supply in the safe!

Unlike mortgage interest rates that are governed by specific factors, interest rates in private money are largely influenced by supply and demand as well as other unique factors.

Supply and Demand, my friend, supply and demand.
