How do you compete with a far lower bid from a questionable contractor?

Short answer. Give the homeowner the means to check for themselves: verify the MHIC license, call references, ask for proof of $50,000 liability insurance, demand a complete written contract, and avoid large upfront payments.

You're the contractor. Pick what you'd do, then see how each choice plays out.

Derek Sloan

Competitor who underbids everyone, uses unlicensed subs, skips permits, and badmouths other contractors to steal clients

You provided a $28,000 estimate for a kitchen renovation. The homeowner calls back: "Derek Sloan said he'd do the same job for $16,000. He showed me pictures of his work and it looked great."

You know Derek's work. You've seen his code violations. You also know his 'portfolio photos' are stolen from other contractors' websites.

Correct
If Derek is legitimate, due diligence confirms it. If he's not, the homeowner discovers it themselves — which is far more convincing than you telling them. Suggest they: (1) verify his MHIC license number, (2) call actual references, (3) ask for proof of $50,000 liability insurance, (4) get a detailed written contract with all required elements, (5) never pay more than 33% upfront. If Derek can satisfy all of that, maybe he's improved. If not, the homeowner will see it without you saying a word.
Risky
Even if true, this can come across as sour grapes from a contractor who lost the bid. If the homeowner tells Derek you accused him of stealing photos, he might threaten defamation. Better approach: empower the homeowner with the tools to verify for themselves. 'Have you done a reverse image search on those portfolio photos?' is more powerful than 'he stole them.'
