Asking for invoices on a cost plus system and getting second quot
We are building a house on a cost plus system with an 8% mark up. Is it common for me to view invoices? Also, can I request or obtain second quotes on work that went over budget?
I actually deal with commercial vendors. I often obtain at least three quotes for any project over $10,000. I then will compare and pick a vendor based on cost savings and reputation etc..
Our original quote for the septic and well system was quoted at $12,000 for septic and $6000 for well. The bank approved our loan based on this quote. He then increased the price by $7,000 due to the fact he did not know how deep the well was going to be. Now he is asking for a check separate from the bank loan. Is that common? He told us he could not a real number on the well until it was measured. I guess it goes down 180 feet. He told us he did not realize it would have to be that deep. Thus I am wanting the builder to get secondary quotes.
