Questions to Ask a New-Construction Builder

By Megan Duncan, REALTOR, MRP · Modern + Main Realty · Moncks Corner, SC


The short answer

Last updated: 2026-07-04

The questions that matter most with a new-construction builder fall into five buckets: warranty, timeline, upgrades, incentives, and representation. Ask what the warranty actually covers and for how long, what happens if the build runs late, what is standard versus a paid upgrade, whether the incentives require the preferred lender, and whether you can bring your own agent. Grab the printable checklist below and take every question with you to the model home.

What are the most important questions to ask a new-construction builder?

The most important questions are the ones that protect your money and your move-in date, and they sort into five buckets: warranty, timeline, upgrades, incentives, and representation. A model home is built to sell you a feeling, so a good question turns that feeling into specifics you can compare across builders. Here is the map.

Bucket What to ask about What a straight answer protects you from
Warranty What is covered, for how long, and how you file a claim Paying later for something you assumed was covered
Timeline The estimated completion date and what happens if it slips Losing a rate lock, a lease, or a move-in date with no remedy
Upgrades What is standard, what costs extra, and when prices lock A base price that quietly climbs at the design center
Incentives What the credit requires and whether the loan behind it competes An incentive you pay back through a higher rate
Representation Whether you can bring your own agent and who pays them Signing a builder-drafted contract with nobody on your side

For the full new-build process from contract to keys, start with the new construction buyer’s guide for the Charleston suburbs. This page is the question list you bring to the sales center.

What should I ask about the builder’s warranty?

Ask the builder to walk you through exactly what the warranty covers, how long each type of coverage lasts, and how you actually file a claim, because “it comes with a warranty” can mean very different things from one builder to the next. Coverage is often split into separate windows for workmanship, systems, and structural items, so get the specifics in writing rather than trusting the brochure.

Bring these to the table:

  • Which parts of the home are covered, and for how long does each type of coverage last?
  • Is there a walkthrough near the end of the first year to log fixes before that coverage ends?
  • How do I submit a warranty request after closing, and what is your response time?
  • Who backs the structural coverage, the builder or a third-party warranty company?
  • What is specifically excluded, and what maintenance is on me to keep coverage valid?

What should I ask about the timeline and delays?

Ask for the estimated completion date in writing and, more importantly, what the contract says happens if the build runs late, because delays are common on new construction and the builder’s paper usually protects the builder on timing. Know your remedy, or lack of one, before you sign, not when your lease is ending.

Questions worth asking:

  • What is the estimated completion date, and how firm is it?
  • What does the contract say if the home is not finished on time?
  • How will you keep me updated, and can I do a pre-drywall walkthrough?
  • If my rate lock expires because of a delay, who absorbs that cost?
  • Can I talk to buyers who recently closed in this community about their timeline?

What should I ask about upgrades and the design center?

Ask what is included in the base price, what counts as a paid upgrade, and when your selections and their prices lock, because the number on the sign is a starting point and the design center is where it climbs. The gap between a bare base home and the fully optioned model can be large, so get the standard-versus-upgrade line drawn clearly first.

Ask the sales team:

  • What finishes and features are standard at the base price?
  • Which of the things I loved in the model are paid upgrades, and what do they cost?
  • Is the lot premium included in the price you quoted, or added on top?
  • When do my selections and their prices lock, and can prices change after that?
  • Which upgrades are hard to add later, and which can wait until after closing?

What is actually negotiable on a new build, and how the give tends to show up in upgrades and closing costs rather than the sticker price, is its own topic. The playbook is at negotiating new construction (coming soon).

What should I ask about incentives and the preferred lender?

Ask exactly what the incentive requires, then compare the preferred lender’s full Loan Estimate against at least one outside quote, because a closing-cost credit or rate buydown is only a good deal if the loan behind it competes. Builders often tie their best incentives to using an affiliated or preferred lender, and sometimes a preferred closing attorney, so the question is whether the total cost over the years you plan to own the home actually wins.

Put these on the list:

  • What exactly do I have to do to earn this incentive?
  • Can I get the incentive with my own lender, or only the preferred one?
  • Will you give me the preferred lender’s full Loan Estimate to compare?
  • Is the credit applied to closing costs, the rate, or design-center dollars?
  • Does the incentive change if I choose a different closing attorney?

Buying with a VA loan adds a few rules of its own on new construction, including appraisal and completion requirements and how a preferred lender fits in. Those specifics live at using a VA loan on new construction in South Carolina.

This is general information, not financial, tax, or legal advice, and I am a real estate agent, not a lender. Any incentive or financing question here is a prompt to compare, not a recommendation; confirm the numbers with your own lender and, for VA specifics, with the VA.

Should I ask whether I can bring my own agent?

Yes, and ask it before your first visit, because most builders will only recognize and pay your own agent if that agent is registered with you from the very first contact at the sales center. The builder’s site agent is helpful, but their duty runs to the builder, so your own agent is the person reading a builder-drafted contract on your side. Whether a new build is even the right move for you versus an existing home is covered at new construction versus resale (coming soon).

Ask up front:

  • Can I bring my own agent, and does the builder pay the agent’s fee?
  • Do I need to register my agent on my first visit for that to count?
  • If my agent cannot come to the first visit, can they register me ahead of time?
  • Who represents me if I do not bring an agent, and who do they answer to?

How do I get the printable builder-questions checklist?

Enter your email below and I will send you a one-page printable version of every question above, organized by bucket, so you can walk into any model home and check them off. If you would also like a quick text as you tour, tick the separate SMS box and add your number. That box stays unchecked unless you choose it, and email works fine on its own. Here is the opt-in you will see (this is the scaffold the site builder wires to the delivery system; the checklist is sent to the email you provide):

The SMS checkbox is unchecked on purpose and must stay that way. I will not text you unless you check it and give me a number, and I will not add your email to anything beyond what you opted into above. That is both the law and how I would want to be treated.

One low-pressure next step: grab the checklist above, or if you would rather talk through a specific community first, send me a note and I will help you set up your builder visits so your representation is protected. No pressure, no obligation.
