How much to budget for construction contingency?
In general, how much would you recommend to budget for construction contingency? Meaning (and I think I understand this correctly), if you are budgeting, say, $100,000 to build a house, you should also budget 10-25% for possible unforeseen overrun. I'm not sure if this means change orders (which we wouldn't do) or just unexpected happenings.
How much did you budget for the unexpected?
