If you own a home in Clark County and plan to buy new construction while selling your home, builder extension fees are changing the math. Many builders now tie those fees to a percentage of the purchase price instead of a flat monthly cost. Understanding how that structure works is key to planning your timeline and protecting your budget.

How Builder Extension Fees Changed

For years, contingent new construction deals followed a predictable rhythm. Your current home didn't close by the builder's deadline, you paid a flat monthly extension fee, you bought more time. It was inconvenient, and you don't want to pay the fee, but it was manageable. A few hundred dollars a month felt more like a speed bump than a barrier.

Builders across Clark County are shifting to percentage-of-purchase-price extension structures. The amount you pay depends on the fee model outlined in your builder's contract.

On a $600,000 home, a flat fee might range from $300 to $500 per month. A percentage-based fee may be several thousand dollars for the same extension period. More builders across Clark County are adopting this approach, and it matters most to move-up buyers.

The Washington State Department of Financial Institutions notes that contingent purchase agreements include specific disclosure requirements. Extension fee structures can vary significantly from one builder contract to another. Reading the contract carefully before signing helps you understand exactly how those terms apply to your purchase.

How the Resale Market Influences Builder Extension Fees

These extension fees are not changing without a reason. It's a downstream effect of what's happening in the Clark County resale market, and that market is creating delays buyers aren't anticipating.

Sellers are still overpricing, and that is stretching the timeline to sell homes. Deals are also falling through at higher rates. As a result, the timeline buyers assume when they sign a new construction contract is often much shorter than the reality.

Let's consider a common scenario that plays out in the current new construction market. A move-up buyer goes under contract on a new construction home and lists their current home, expecting it to sell quickly. It goes under contract within a week, right at the asking price. Everything looks good, then the deal falls through after a few weeks.

The home comes back on the market, but momentum is gone. Showings slow down, and buyers hesitate to make offers. Meanwhile, the builder's closing timeline hasn't changed, and the clock is ticking.

A few weeks later, that same home may still be sitting, now requiring a $10,000 price reduction just to get back into play. That $10,000 reduction looks different when you realize what it prevented: triggering a percentage-based extension fee on an active new construction contract.

There's another important consideration for contingent buyers in new construction. Even if you receive an offer on your current home, most Clark County builders won't accept a contingent-on-contingent structure. Builders typically look for a straightforward transaction chain. If your buyer also needs to sell a home, the builder's contingency requirements may not be met. Reviewing those terms early helps you plan your timeline with greater confidence.

What to Get Right Before You Sign a New Construction Contract

Two factors deserve careful attention before signing a new construction contract.

The first concerns setting the right price for your current home. Know what your home is likely to sell for in today's market. Focus on current market conditions rather than past sales or nearby listing prices. Get a realistic comparative market analysis and have the harder conversation about what price actually moves the home within the builder's window.

Marci Caputo has watched this tradeoff play out repeatedly in Clark County new construction transactions.

"If this thing falls through and then all of a sudden you're putting it back on the market, and it's a slower market, you're going to have to reduce the price. That's one of those things where maybe you take an offer that is $10,000 less where it's not contingent."

Holding out for an extra $10,000 in asking price is not worth triggering a percentage-based extension fee on a $600,000 build. That's a trade most buyers don't realize they're making until after the fact.

The second point is builder requirements. Most Clark County builders require your current home to be listed in the MLS within seven business days of signing the new construction contract. Some builders also require the home to reach pending status before fully executing the purchase agreement. Understanding these contract requirements early helps you plan your timeline and stay on track.

"That's where it gets very expensive for everyone involved if you do not sell your home or your home falls out of contract while you're having a house built. Especially right now, because selling your current home is not as easy as it had been, say, 2022."

The Seasonal Window for Builder Flexibility

Builder traffic at model homes slows in August, and that slowdown tends to push builders toward more flexibility on extension timelines and contingency terms. When foot traffic drops, builders become more willing to work with buyers who need a little more runway.

Those windows close quickly when buyer activity picks back up. A builder who offered extension flexibility in August may enforce percentage-based fees without exception by October.

This is one of the areas where knowing the specific builder's current posture, not just their standard contract language, changes your negotiating position. A buyer's agent with experience in the Clark County new construction market has had those conversations regularly. That current, builder-specific knowledge has real dollar value in a contingent transaction.

Understanding how builder contracts are structured at the clause level, including material escalation and contingency language, is important. I touched on some of this in a recent post about material escalation clauses.

Common Questions About Contingent Sale Extension Fees in New Construction

What is a builder extension fee in new construction?

A builder extension fee is a charge that may apply when a buyer needs additional time to close. This often happens when a contingency, such as the sale of a current home, is not completed by the original closing deadline.  Extension fees compensate the builder for holding the home off-market while the buyer resolves the delay. Fee structures vary by builder and have been shifting significantly in Clark County.

How are contingent sale extension fees calculated in Clark County?

Clark County builders are increasingly moving from flat monthly fees to percentage-of-purchase-price structures. On a $600,000 home, a flat fee might run a few hundred dollars per extension period. A percentage-based fee on that same home can run several thousand dollars for the same period. Each builder's contract outlines its own extension fee structure. Reviewing those terms before signing helps you understand how they apply to your purchase. 

Can I buy new construction in Clark County if I haven't sold my current home?

Yes, contingent new construction contracts do happen in Clark County, and many move-up buyers navigate them successfully. The key factors include pricing your current home accurately for today's market. Your selling timeline also plays an important role in the buying process. Before signing, take time to understand your builder's extension and contingency terms.

Will a builder accept a contingent offer if my buyer is also contingent?

Most Clark County builders will not accept a contingent-on-contingent structure. If your buyer is also selling a home before closing, the builder's contingency requirements may be different. Reviewing those requirements early helps you understand how they apply to your transaction. Your chain needs to be cleaner for the builder to consider the contingency resolved.

What does a builder typically require when you have a home to sell?

Most Clark County builders require your current home to be listed in MLS within seven business days of signing the new construction contract. Some builders require the home to reach pending status before they fully execute the purchase agreement. These milestones are part of the builder's purchase agreement. Understanding them early helps you plan your timeline and move through the buying process with confidence.

Can bridge financing help with a contingent sale on a new construction home? 

Bridge financing lets you borrow against the equity in your current home to fund your new construction purchase before your existing home sells. This removes the contingency entirely, which can reduce the need for builder extension fees. The main consideration is managing two loan payments for a period of time. Not every buyer qualifies, and lenders evaluate bridge loan eligibility based on debt-to-income ratio (DTI) and loan-to-value ratio (LTV) on both properties. Consult a qualified lender early if you're exploring this route. Our post on managing your contingent sale timeline covers how to sequence this decision.

Is it worth working with a new construction specialist instead of a general agent for a contingent purchase?

A buyer's agent who specializes in new construction has experience reviewing builder contracts across multiple communities. They understand how different builders apply extension fee policies and contingency requirements. They also know when builders may offer greater flexibility based on market conditions and seasonal trends. In a contingent transaction, that knowledge reduces financial risk. A general agent who rarely works in new construction may not know which contract terms are negotiable or when to push back.

Build Your Timeline With Intention

Builder extension fees now influence more than just timing in a contingent purchase. They shape pricing decisions, negotiation strategy, and overall financial risk. Buyers who understand these structures early stay in control of the process and make better decisions.
