5 Ways Builders Are Quietly Overcharging You in Cabo

Home Construction Costs in Los Cabos

I'm not a builder. I stay in my lane — real estate and design/build project oversight — but over the past five years I've made a lot of introductions to builders, and I hear about it every time one of those relationships goes sideways. Recently I've been posting about this on social, and the response has been bigger than I expected. One post from yesterday already has 30+ comments of people sharing their own version of these stories.

So here are the five patterns I keep seeing right now, straight from people who've reached out to me directly.

1. Construction Fishing

You sit down with a builder, you like what you see, the price is good. Work starts on time, on budget, with photos to prove it. Then you hit 70-80% complete, and the builder needs more money to finish. Deep down, they knew from day one they couldn't hit that number — they just weren't going to tell you until you were too deep in to walk away.

To be fair, not every overage is the builder's fault. Change orders and scope changes on the client's side happen too. But when it's a pattern — and I'm hearing about it constantly right now — that's not a coincidence.

2. The Glorified Subcontractor

Building a house has layers: foundation, windows, carpentry, cabinets, pool, AC, solar. Depending on the builder, some of that work gets subbed out — and that's not automatically a red flag.

The problem is a specific type of builder who subs out *everything* and marks it up double. You're quoted one number, the actual work costs half that, and the builder pockets the spread. I've had another builder tell me directly about a case like this: the subcontracted crew did solid work, the client ended up with a finished house — they just paid twice what it should have cost to get there.

3. Builders Without the Bandwidth

I've seen this in property management too, not just construction: someone does great work, gets a wave of referrals, then scales past what they can actually handle and starts dropping the customer service that got them there in the first place.

With builders, it looks like this: a builder takes on a bigger, higher-end project and quietly puts your build on standby — sometimes, according to clients, using funds from your build to get the new one moving. One case that reached me: two neighbors building at the same time, same builder, final cost came in over 100% above the original estimate, more than a year behind schedule, and the pool still isn't built. The builder had picked up a much higher-end job nearby and paused both of their projects to chase it.

Before you hire anyone, ask what else they have going on. A builder who's honest about their bandwidth is worth more than one who tells you what you want to hear.

4. Cost-Plus Pricing (Handle With Care)

With material prices swinging the way they have — inflation, supply chain issues — some builders are now offering cost-plus models: here's what it costs us, here's our markup, and fluctuations pass through to you either way.

That's a legitimate model, and it's common in the US, which is why a lot of buyers are comfortable with it. But it only works if you trust the builder completely, because you're now relying on them to be honest about fluctuations they have every incentive to pad. Ask directly in the interview process whether a builder uses cost-plus pricing, and pay attention to how they answer — not just what they say.

5. Material Substitution Scams

This one isn't always the builder's fault. A remote build in East Cape had copper wiring ordered and paid for — a supplier tried to slip in aluminum instead during installation. It got caught before the electrical work was finished, but it's a reminder that the risk isn't only the builder. It's every supplier and crew member down the chain, especially in more remote areas where oversight is thinner and providers know it.

Even an honest builder with multiple projects running can get exposed here if they're not on-site enough to catch it.

The Common Thread

Most people building here are only going to do it once. That matters more than people realize — to a builder who knows they'll never see you again, this can feel like a one-time transaction instead of a relationship. Get multiple quotes, ask pointed questions about bandwidth and pricing models, and don't assume a good build means a good process. If it feels too good to be true, it usually is.

If you want a referral to someone I actually trust — builder, retaining wall specialist, whatever the project needs — reach out. I'm selective about who gets that referral, and I'd rather point you in the right direction from the start than help you clean up a mess later.
