How draws actually work
A construction loan doesn’t fund at once. Money is released in stages against work completed. You request a draw, an inspector verifies percent complete, the lender releases funds, and you pay subs. Repeat until the house is finished.
The mechanic is sound. The problem is turnaround. A draw process that takes weeks instead of days means subs waiting on money, and subs who wait go work for someone else. That shows up as schedule slippage, which shows up as carrying cost.
