How to Vet a Contractor as a Real Estate Investor (The Hard-Earned Checklist)

A hard-earned checklist for vetting contractors as a real estate investor. Stop getting burned by following this due diligence process before signing.

By Seller's Little Helpers Team · April 13, 2026

I've watched investors hand $20,000 to a guy they met on Facebook Marketplace. No license check. No insurance verification. No references called. Then they're shocked when the project goes sideways.

Vetting a contractor takes about 2 hours. Fixing a bad contractor hire takes months and costs thousands. Pick your pain.

The Non-Negotiable Checks

Before you even talk about your project, verify these:

1. State contractor license. Look it up yourself on your state's licensing board website. Don't accept a photo of a license. Don't take their word for it. Licenses expire and get revoked. Check the current status.

2. General liability insurance. Ask for a certificate of insurance (COI) and call the insurance company to verify it's active. Minimum $1M in general liability. If they can't produce a COI in 24 hours, walk.

3. Workers comp insurance. If they have employees (not just subs), they need workers comp. If a worker gets hurt on your property and the contractor has no workers comp, guess who's liable? You.

4. Business registration. Are they an actual business entity (LLC, corp) or just a guy with a truck? Business registration means they have something to lose, which means they have incentive to perform.

The Reference Check That Actually Works

Don't ask for references. Every contractor has three happy clients they'll send you to. Instead:

  • Ask for the names of their last 5 clients, not their best 5
  • Ask those clients: "Would you use them again?" and "Did the project finish on time and on budget?"
  • Drive by completed projects if you can. Does the work look right from the outside?
  • Ask other investors at your local REIA. Word travels fast in this community.

The Bid Analysis

Get bids from at least three contractors. Then compare:

  • Line-item detail. A bid that says "kitchen remodel - $12,000" tells you nothing. You need line items: demo $800, cabinets $3,200, countertops $1,800, etc.
  • Labor vs. materials separation. If labor and materials are bundled into one number, you can't verify what you're paying for.
  • Timeline commitment. A bid without a timeline is a red flag. "We'll get to it when we can" is not a schedule.
  • Payment terms. If they want 30-50% upfront, that's your cue to ask about weekly draws.

The Conversation Test

Sit down with the contractor for 30 minutes. Ask these questions:

  • "What's the biggest project that went wrong for you, and what happened?" If they can't answer honestly, they're either lying or haven't done enough work.
  • "How do you handle change orders?" You want to hear "written, priced, and approved before work begins."
  • "What's your current workload?" If they say they can start tomorrow, be suspicious. Good contractors are usually booked 2-4 weeks out.
  • "Will you work on weekly draws instead of a deposit?" Their reaction tells you a lot. Professionals say yes. Guys who need your money to operate say no.

Red Flags That Should End the Conversation

  • No written contract. Walk away.
  • Pressure to pay a deposit immediately. Walk away.
  • "I don't need a license for this type of work." Maybe true, but it tells you about their professionalism. Walk away.
  • Can't provide proof of insurance within 24 hours. Walk away.
  • Bad-mouths every previous client. Walk away.
  • The bid is significantly lower than everyone else's. That's not a deal. That's a future problem.

The Payment Structure Test

Here's the ultimate vetting question: "Will you work on weekly labor draws with no deposit?"

A contractor who says yes is telling you:

  • They have the financial stability to float a week of labor
  • They're confident in their work
  • They don't need your money to fund other projects
  • They're willing to be held accountable weekly

A contractor who says no is telling you something too. Listen.

Frequently Asked Questions

What is the most important thing to check when vetting a contractor?

Verify their state contractor license and insurance yourself. Don't take their word for it. Check the licensing board website and call the insurance company directly. This takes 30 minutes and prevents the biggest disasters.

How many bids should I get for a rehab project?

At least three. Compare line-item detail, labor vs. materials separation, timeline commitments, and payment terms. The cheapest bid is rarely the best value.

What payment structure should I use with a new contractor?

Weekly labor draws with no deposit. It limits your risk to one week of work, creates accountability, and tells you a lot about how the contractor runs their business based on whether they accept the terms.
