If you’re more comfortable operating an iPhone than a circular saw, you could act as your own general contractor on some home improvement projects. That means you hire, schedule, and pay the carpenters, plumbers, and other tradesmen yourself. You’ll save 10% to 20% of the job cost, which is the contractor’s typical fee.
When it pays: If it’s a small job that requires only two or three subcontractors, and you have good relationships with top-quality professionals in those fields, consider DIY contracting.
When it costs: When you don’t have an established network of reliable workers, time to supervise, construction experience to spot problems, and the skill to negotiate disputes between subcontractors, your project and budget are at risk.
