Should You Use the Developer for Pre Construction Upgrades or Hire Outside Vendors?

One of my agents recently asked me a good question regarding a client who purchased an expensive pre construction property in Cabo that’s nearing completion.

The question was simple:

Should the buyer do upgrades directly through the developer or save money by hiring outside contractors after delivery?

The answer is not always black and white because there are advantages and risks to both approaches. Most buyers immediately focus on cost, but in reality, the bigger issue is usually liability, warranties, and future headaches.

The Cost Difference

In many pre construction projects, developers charge significantly more for upgrades and customization work.

It is not uncommon for developers to charge almost double compared to what an outside contractor might quote for similar work. Buyers often look at pricing for things like:

• Storm shutters

• Rooftop kitchens

• Pergolas

• Lighting upgrades

• Smart home systems

• Custom carpentry

• Built in furniture

• AC modifications

• Railings and glass work

…and quickly realize they may be able to save a substantial amount of money by hiring someone independently after taking possession.

From a pure pricing standpoint, outside vendors often win.

However, this is where things can get complicated.

The Warranty Problem

The issue is that once outside contractors begin modifying the property, developers can sometimes use that as an excuse to deny responsibility for future problems.

This becomes especially important when the upgrades involve areas connected to waterproofing, roofing systems, electrical systems, drainage, structural penetrations, railings, or plumbing.

For example, if an outside contractor installs something incorrectly and water intrusion later becomes an issue, the developer may immediately point fingers and claim the outside work caused the problem.

Even if the developer is partially responsible, the situation can quickly turn into a battle over liability.

A Real Example

I personally dealt with a situation involving clients who purchased a pre construction home. The developer did not have a preferred vendor list, so the buyers hired an outside provider to install storm shutters on both levels of the home.

Later on, heavy rain caused water intrusion issues.

The developer claimed the outside contractor’s work and railing modifications caused the leaks. Personally, I thought the explanation was questionable, but from the developer’s perspective, it gave them an argument to shift responsibility away from themselves.

Eventually the issue was resolved and the developer did step up, but it created delays, frustration, and unnecessary conflict that could have potentially been avoided.

Why Developers Sometimes Push Their Vendors

A lot of buyers assume developers push their preferred vendors simply because they want to make extra money.

In some cases, that is absolutely part of it.

However, there is also another reason: control.

Developers want to know who is modifying the property because once multiple outside contractors start drilling into roofs, changing drainage, modifying railings, or adjusting electrical systems, it becomes much harder to determine who caused problems later.

That is why some developers either strongly encourage or outright require buyers to use approved vendors during the warranty period.

What Buyers Should Consider

Before deciding whether to use the developer or an outside provider, buyers should ask themselves a few important questions:

1. How sensitive is the upgrade?

Cosmetic upgrades like furniture, paint, or decor are very different from modifications involving waterproofing, roofing, plumbing, or electrical systems.

The more technical the upgrade, the more risk there is if problems arise later.

2. What does the warranty actually say?

Many buyers never fully review warranty language.

Some developers have clauses limiting coverage if outside modifications are made. Others are much more flexible.

This is something buyers should clarify before making decisions.

3. Does the developer have approved vendors?

Some developers maintain preferred vendor lists specifically to avoid future liability disputes.

If buyers want to use outside providers, it may still be possible if the contractor is approved beforehand.

4. How reputable is the developer?

Not all developers handle warranty situations the same way.

Some step up quickly and protect their reputation. Others look for every possible reason to avoid responsibility.

The quality of the developer matters just as much as the quality of the contractor.

The Bigger Picture

A lot of buyers focus only on immediate savings without thinking about long term protection.

Saving money upfront may absolutely make sense in certain situations. However, buyers also need to understand that once outside contractors become involved, the developer may have an easier time disputing future warranty claims.

Sometimes paying more through the developer actually reduces long term risk and protects the buyer from future headaches.

Every project is different. Every developer is different. Every warranty is different.

The key is understanding the tradeoffs before making the decision.
