Buying a New Construction Home: What You Need to Know Before You Sign

A brand-new home with modern finishes, the latest appliances, and no one else's wear and tear — it is easy to see why new construction is so appealing. But the process of buying a newly built home is significantly different from buying an existing one, and buyers who do not understand those differences can end up with costly surprises.

Here is everything you need to know before you walk into a model home or sign a builder contract.

When you buy an existing home, you negotiate with a homeowner who has an emotional attachment to the property and a specific number in mind. When you buy new construction, you are dealing with a corporation — a production builder or a custom home builder — that sells homes as a business.

There are three main types of new construction:

Production homes are built by large national or regional builders in planned communities. You choose from a set of floor plans and a menu of upgrades. These are the most common type of new construction and are typically the most affordable.

Semi-custom homes give you more flexibility — you can modify floor plans and make more significant design choices, but you are still working within the builder's framework.

Custom homes are built entirely to your specifications on a lot you own or purchase separately. This is the most expensive and complex option, involving an architect, a general contractor, and a much longer timeline.

This is the single most important piece of advice in this entire article: bring your own buyer's agent — or at least register their name — before you visit a model home or sales office for the first time.

The sales agent at the builder's model home works for the builder, not for you. Your own buyer's agent represents your interests. They can:

• Review the builder contract and flag problematic clauses
• Negotiate upgrades, closing cost contributions, or price reductions
• Advise you on which upgrades are worth paying for and which are not
• Help you understand the true cost of the home beyond the base price
• Represent you if disputes arise during construction

Most builders pay the buyer's agent commission, so having your own representation costs you nothing. But if you visit the sales office without registering an agent, many builders will not allow you to add one later.

The advertised price of a new construction home is almost never what you will actually pay. Builders use a base price to get you in the door, then present you with a long menu of upgrades in the design center.

Before you get excited about a base price, ask the sales agent what a "typical" buyer spends on upgrades. Then add that number to the base price to get a realistic picture of what you will spend.

Also ask what is specifically not included in the base price. Common exclusions include:

• Landscaping and sod
• Window treatments
• Appliances (sometimes)
• Fencing
• Driveway paving
• Finished basement or bonus rooms

Builder contracts are written by the builder's attorneys and are designed to protect the builder. Common provisions that surprise buyers include:

Extended closing timelines with limited recourse. Builders often reserve the right to delay closing by months without penalty.

Limited warranty terms. Builder warranties sound comprehensive but often have significant exclusions and short windows for certain types of defects.

Mandatory arbitration clauses. Many builder contracts require you to resolve disputes through arbitration rather than the courts.

Earnest money may be non-refundable. If you back out, you may lose your earnest money deposit — which can be 3-5% of the purchase price or more.

Have a real estate attorney or your buyer's agent review the contract before you sign.

New construction homes have defects. Framing errors, improper grading, HVAC installation issues, plumbing problems — these happen regularly, even with reputable builders.

Hire an independent inspector at two key stages:

Pre-drywall inspection: Before the walls are closed up, an inspector can examine the framing, plumbing, electrical, and HVAC rough-in work.

Final walkthrough inspection: Before closing, have an inspector do a full review of the completed home.

The cost of two inspections — typically $600-900 total — is trivial compared to the cost of discovering a major defect after closing.

A new construction home can be an excellent choice. You get modern systems, energy efficiency, a builder warranty, and the satisfaction of being the first person to live in the home. But the process requires more due diligence than buying an existing home — not less.
