Avoid Contractor Scams: 5 Red Flags That Cost Investors Thousands

TLDR

Most contractor scams are not criminal. They are small, lazy drift that adds up: gray scope of work, change orders with a fear tax, slow disappearing acts, and licensed guys holding you hostage on permits. Fix this by writing the scope three ways, breaking every change order into tasks, and never going soft on timelines.

The Criminal Stuff First

There is a set of contractor moves that is flat criminal. A contractor just got 8 years in federal prison for stealing over a million dollars from more than a dozen people. That one is rare. But the lighter versions are common.

• Material heist: your contractor buys material for your job, then uses it on another house.
• Swap out: he tells you the hvac is broken, charges you for a new one, takes the good one, and sells it to another investor. This one catches out-of-state investors all the time.
• Photoshop: he sends you pictures showing the flooring and cabinets are in. You fly out and most of the job is barely started.
• Cash and dash: you pay upfront, he never comes back.

The Cash and Dash

Paying a contractor in full before work is done is the easiest way to lose the money. The money is the only real lever you have on a 1099 sub. Never pay in front of the work.

These are the malicious ones. Real, but rare. The everyday scams do more damage across a career because they look like normal business.

Scam 1: The Abe Lincoln

This one starts with the most dangerous phrase in real estate. “Don’t worry, man. We’ll just shake on it.”

You want to build relationships. You should. But a contractor who knows more than you can see blood in the water. New investor, maybe out of state, maybe a first flip. He talks in ambiguous terms on a scope of work, and when something comes up later, he gaslights you into thinking you already agreed.

I got caught in this one. Cost-plus arrangement, loose scope. He told me we had a conversation where I said “if you find something, just go ahead.” What I actually said was “if you find something, let me know what it is going to cost so I have options.” He tore out a full bathroom because of some rot, redid it, and handed me the bill. What am I going to do, refuse to pay? The work was done.

Fix: Scope of Work in Three Ways

I do not sign contracts with contractors. Contracts add friction, and you are never going to hunt a guy down in court over a few grand. Instead, I set up the scope of work in three ways on the same walk-through.

1. Written. I usually write the scope in advance.
2. Verbal. We walk the job site together and confirm.
3. Video. I walk the same property with a camera rolling, saying what is going to happen in each room.

Then I send the written and the video when I ask for a bid. “Give me your bid based on this.” Now if something comes up later, we have three forms of the same agreement. Most of the time the problem does not come up at all, because communication errors are most of what causes these fights in the first place.

A gray scope of work is what lets a contractor turn a mistake into your bill.

Scam 2: The Loss Leader

Grocery stores put two porterhouse steaks for the price of one on the end cap to get you in the door. The melons inside are triple price. The bottled water is 100 times what tap water costs. The steak is the loss leader.

Contractors do the same thing. The initial bid comes in tight, maybe 0 to 5 percent margin, sometimes at cost. They know that once they are in the walls, change orders are where the real markup lives. Fifty, sixty, seventy percent on a change order. That is where they make the year.

Fix: Break Change Orders Into Tasks

Every change order carries what I call the fear tax. The contractor is not always being malicious about it. Sometimes they are scared too. “Termites in the wall” sounds bad and unknown, so both sides pad the number.

You kill the fear tax by breaking the job down into tasks.

Now each task has material, labor, and a reasonable markup. No fear tax over the top.

Then you walk it with the contractor as if you are trying to learn. “So the demo, that is probably a half day, right? Not a high-skill guy.” “The framing, that is maybe another day. Material is 50 to 100 bucks, it is just a wall.” “Drywall. Paint. And we are calling a termite company for the treatment, right? What do they charge?”

By the end, you are looking at the original 10,000 dollar bid and you say: “I am not seeing how we got to ten thousand. Am I missing something?”

Usually they come back with 3,000 and a story about what they were originally thinking. Sometimes they hold at a higher number, and that is fine, but you do not haggle. You exit gracefully. “I actually have a crew that does nothing but termite work, their prices are insane on this specific thing. I am going to call them and see.” Then you bring in the specialist. Your relationship capital with the first guy stays intact for the next job.

Pro Tip

When a contractor brings a big number for something scary, do not fight the number. Fight the job definition. Break one scary job into five regular tasks and the fear tax evaporates on its own.

Scam 3: The Black Hole

You hire a guy, he works for a week, then you cannot get a hold of him. He has not fully ghosted, because that would be easier to deal with. He just barely holds on. A week goes by with no one on site. Right when you are about to fire him, he shows for one day. Then another week. He drops in again just before you cut him loose. That is the black hole.

Fix: The Reasonable Ultimatum

Usually you are pissed when you have to have this conversation. Leave the anger at the door. Take deep breaths. Then be direct, but fair.

“You are a 1099 subcontractor, not an employee. I cannot tell you where to be every day. But it has been a couple weeks and I am bleeding money on this thing. I need to get somebody else in here if this does not move. But you had the initial deal with me, so I want to give you the shot. I need the floors done by next Friday. That is more time than you need. If I show up Friday and the floors are not done, I am cutting you loose. We settle up on the work you have already done. No problem.”

Don’t be soft. Don’t be fragile. Tell him exactly what is going to happen. Direct, but fair.

Scam 4: The Hostage

This one hits with licensed trades. Mechanical, electrical, plumbing. The guys who pull permits.

Three bids come in on a rewire. Two come in at 13 or 14 grand. The third comes in at 8 grand. You ask him how he is so cheap. “Those other guys don’t know what they’re talking about. You don’t need a panel, don’t need a meter, don’t need to rewire that.” You hire him. He does the work. Inspector shows up and says you need a panel, a meter, and a full rewire.

Now the guy is back with another 8 grand bid because the inspector said so. Total: 16 grand. You could have just hired the first guy for 14. But he already pulled the permit, and getting him off of it is a whole city process. You are stuck.

Whether he was malicious or just dumb, the result is the same.

Fix: Knowledge and Presence

• Only buy properties you can physically visit. I only buy properties that are in my backyard. Leadership is presence.
• Gain the knowledge of what the real scope actually needs to be. If you do not know what a rewire involves, you are the prey.

If I am acting as my own GC and hiring the subcontractors directly, I have to be able to call BS when a bid is suspiciously low. Low bids on licensed trades are the most expensive bids you can take.

Key Concept

Knowledge times experience equals skills. Skills are the true wealth. Once you have them stacked up, you stop being the mark.

The Real Prevention

Most scams are not malicious. They come from a contractor being overwhelmed, disorganized, or scared. The fear tax goes both ways. The black hole happens because the guy has three other job sites falling apart. The loss leader happens because his residential competition is doing it too.

The prevention is structural. Write the scope three ways. Break every change order into tasks. Hand out ultimatums early and clearly. Pay on checkpoints, never in front. Build the knowledge yourself so you can call it when something does not add up.

Some of the best friends I have are contractors I work with. That is not in spite of this stuff, it is because of it. Clean structure makes a clean relationship.

FAQ

Should I use formal contracts with contractors on small flips?

I don’t. The contracts add friction, and the amount of money at stake on any single scope item is almost never worth chasing through a court. Scope of work in three ways gives you better protection because it prevents the argument in the first place.

What do I do if a contractor refuses to break down a change order into tasks?

That is the contractor telling you he does not want the fear tax killed. Tell him you have a specialty crew for that specific work and you want to get their number. If his bid was reasonable, he will usually come back down. If not, bring in the specialty crew for real.

Can the black hole ultimatum damage the relationship long-term?

Not if you deliver it fair. Calm voice, specific deadline, more time than he actually needs. Acknowledge that he probably has other job sites going on. Most contractors respect you more after you set a hard line. The ones who don’t were going to ghost you anyway.

I just started flipping. How do I hire licensed trades without getting the hostage treatment?

Do not take the cheapest bid on licensed work. Mechanical, electrical, and plumbing are where under-bidding gets you in trouble later. Talk to two or three licensed guys, ask them to explain what the job actually requires, and pick the one whose scope matches what the others are saying. If one guy is way low, there is usually a reason.

Is it worth hiring a general contractor to avoid all this?

Not in my opinion. A GC just marks up the same subs and the same mistakes, and you lose the edge that knowing your scope gives you. Acting as your own GC forces you to learn the stuff that makes you a real estate investor. The knowledge pays back forever.
