A brand-new home can still come with serious issues.

Most buyers assume a freshly built home is flawless. Builders assume you won’t notice — or won’t push back. Construction quality varies enormously based on the local crew, the site manager, and how busy the builder was that season.

The builder’s sales agent works for the builder. Their job is to close the deal. My job — as your buyer’s agent — is to make sure you get everything promised, documented in writing, before you sign at closing.

💧

Water Intrusion

Window leaks, improper flashing, grading that channels water toward the foundation.

🌡️

HVAC Defects

Undersized systems, unbalanced airflow, improperly connected ductwork — invisible until your first summer.

🏗️

Foundation Settlement

Early settlement shows up as drywall cracks, sticking doors, or uneven floors within the first year.

🔌

Electrical & Plumbing

GFCI failures, loose fittings, shower leaks not caught before drywall went up.

Unresolved Punch Lists

Items promised at contract that vanish from conversations once you’ve signed the closing docs.

DR Horton, Lennar, K. Hovnanian — an honest take

These are three of the most active builders in New Jersey. Here’s what I consistently see from buyers who’ve worked with each of them.

D.R. Horton

What works
  • Large inventory across NJ communities
  • Competitive base pricing
  • Established documentation processes
Watch out for
  • Workmanship varies by site crew
  • Warranty response times can be slow
  • Pressure to use their in-house lender

Lennar

What works
  • Popular NJ communities, good amenities
  • “Everything’s Included” packages
  • Active resale markets in their neighborhoods
Watch out for
  • Drainage complaints are a recurring theme
  • Construction quality inconsistent across sites
  • Contract language favors the builder

K. Hovnanian

What works
  • Broader customization options
  • Range of sizes and configurations
  • Long-standing NJ presence
Watch out for
  • Buyer communication during build can be spotty
  • Warranty follow-through complaints reported
  • Upgrade pricing adds up quickly

My actual recommendation

Don’t decide based on the brand name. The builder’s sign matters far less than the specific community, the site superintendent, and the local subcontractors doing the actual work. What I evaluate for buyers:

  • Homeowner feedback from that specific community — not national reviews
  • Whether the site superintendent is responsive before you close
  • What’s actually in the contract — and what we can push to change

Three inspections. Most buyers only do one.

Missing any one of them is how problems become your expense instead of the builder’s.

1

Pre-Drywall

During construction
  • Framing & structural elements
  • Electrical rough-in
  • Plumbing rough-in
  • HVAC ductwork placement

The only stage where problems are still fixable without tearing out walls.

2

Pre-Closing

Before you sign at the table
  • Roof and attic
  • All appliances and systems
  • Every door, window, cabinet
  • Drainage grading

Leverage is highest here. Once you close, it’s much harder to get things fixed.

3

11-Month Warranty

Before year-one warranty expires
  • Settlement cracks & shifting
  • Drainage issues visible after weather
  • HVAC performance after a full season
  • Roof behavior after rain and snow
Most buyers skip this

Issues caught before closing — and what they’d cost after

These are the types of problems a buyer’s advocate helps you document and negotiate before they become your expense.

HVAC

Improperly Connected Ductwork

Multiple supply ducts not sealed — discovered during pre-closing walkthrough, corrected at builder’s cost.

$2,500–$4,500
Estimated post-closing repair cost
Drainage

Water Pooling at Foundation

Grading directed water toward the home — negotiated as a builder repair before keys were handed over.

$5,000–$20,000+
Depending on severity and remediation
Roofing

Missing Flashing at Penetrations

Improper installation around roof vents — documented at inspection, corrected at builder’s cost before closing.

Water damage risk
Uncorrected, this becomes a structural issue

You need someone in your corner — not the builder’s.

The builder’s sales office is staffed with professionals whose job is to close the deal at their terms. My job is to make sure you walk out of closing with exactly what you were promised.

📄

Contract Review

Builder contracts are written to protect the builder. I walk through them line by line so you know what you’re agreeing to.

🔍

Inspection Coordination

I recommend independent inspectors and help you organize all three phases at the right moments.

📝

Punch List Tracking

Every promised item in writing, tracked to completion. Nothing gets forgotten between signing and closing.

🤝

Negotiation Support

Upgrades, credits, concessions, closing costs — from a position of information, not hope.

“My commission on new construction is paid by the builder — it costs you nothing to have representation. There is no good reason to walk into that sales office without your own agent.”

Before you walk into that sales office

Is a new construction inspection really necessary?

Yes. Many inspectors routinely find defects in brand-new homes. The builder’s municipal inspections confirm code compliance — they don’t evaluate workmanship quality or installation details.

Do builders allow independent inspections?

Most do, though each builder has its own scheduling policy. Getting this confirmed before you sign the purchase agreement is part of what I help buyers establish upfront.

Should I use the builder’s preferred lender?

Builders offer incentives tied to using their lender. These can be real value, but may be offset by higher origination fees. Always compare the full cost picture with an independent mortgage broker first.

What is the 11-month warranty inspection?

Most new construction homes come with a one-year builder warranty. An 11-month inspection is scheduled before that expires — your final chance to document and submit defects for builder repair at no cost to you.

Does it cost me anything to use a buyer’s agent with a builder?

No. On new construction, the builder pays the buyer’s agent commission. Not having an agent doesn’t lower your purchase price — it just removes your advocate from the table.

Is buying from DR Horton or Lennar a bad idea?

Not necessarily. The brand matters far less than the specific community, the site superintendent’s track record, and the subcontractors on that project. I help buyers evaluate those factors, not the name on the sign.
