Key Takeaways
- Red flags include large upfront payment requests, no written contract, significantly low bids, and poor communication.
- Document all contractor issues with photos and written references to the SOW.
- Maintain a roster of 3-5 vetted contractors per trade as backup options.
- A reliable contractor at 10-15% premium is typically cheaper than the lowest bidder in total project cost.
Contractor problems are among the most frustrating and costly pitfalls in fix-and-flip investing. From outright fraud to simple incompetence, contractor issues can blow budgets, extend timelines, and produce substandard work that reduces the sale price. This lesson provides tools for preventing and managing these situations.
Contractor Red Flags
Several warning signs predict contractor problems. Requesting large upfront payments (more than 10% of the project cost). Refusing to provide a written contract or detailed scope of work. Significantly underbidding other contractors (they will find ways to increase the price or cut quality). Being unavailable or unresponsive during the bidding process (communication will only get worse). Lacking verifiable references or refusing to provide them. Having an unstable workforce (constantly rotating crew members indicates management problems). Unable to provide proof of insurance or licensing. Offering verbal-only change orders rather than documented written ones. Any single red flag warrants caution; multiple red flags should disqualify the contractor.
Managing Contractor Disputes
When contractor problems occur, response speed and documentation are critical. For quality issues: document the deficiency with photos, reference the specific SOW line item that was not met, and provide written notice requiring correction within a specified timeframe. For timeline delays: reference the contractual completion date, document the delay and its cost impact, and invoke per-day penalty clauses if applicable. For abandonment (contractor stops showing up): send written notice of default with a cure period, begin sourcing replacement contractors immediately, and consult an attorney about lien and contract rights. For disputes over payment: require lien waivers with every payment, never pay for uncompleted work, and maintain a holdback (15% of final payment) until all punch list items are resolved.
Prevention Systems for Contractor Issues
The best approach to contractor problems is preventing them. Implement these systems: maintain a roster of 3-5 vetted contractors for each trade so you always have backup options. Use milestone-based payment schedules that ensure the contractor has financial incentive to complete each phase. Conduct twice-weekly site visits with documented photo reports. Hold weekly progress meetings (even 15 minutes via phone) to maintain communication. Build long-term relationships with reliable contractors by providing steady project flow—your best contractor relationships develop over 5-10 projects. Finally, pay good contractors promptly and fairly—slow payment drives the best contractors to other clients.
Common Pitfalls
Choosing the cheapest contractor bid without considering quality and reliability
Risk: The cheapest bid often leads to the most expensive project through delays, rework, and change orders
A reliable contractor at a 10-15% premium is almost always a better value. Evaluate total project cost, not just bid price.
Not maintaining written documentation of contractor agreements and communication
Risk: No recourse in disputes without written evidence of the scope, terms, and agreed-upon milestones
Document everything in writing: contracts, change orders, progress reports, and all communications about scope or quality.
