Builder contingent sale extension fees in Clark County have always been part of new construction purchase contracts. What changed at the end of 2024 is how expensive they became, and how important it is for buyers to understand them early.

That is significant for move-up buyers in Southwest Michigan planning to sell their home and use the proceeds to close on a new build. Understanding that clause and how to manage timelines can make a significant difference.

Marci Caputo is a Managing Broker and co-founder of New Construction Market Experts (NCME) in Vancouver, WA, with 25+ years of real estate experience. She specializes in connecting buyers with new construction homes across SW Washington, making the process buyer-centric, efficient, and economically advantageous.

The Reason Behind Clark County’s New Contingent Sale Extension Fees

When a move-up buyer needs to sell an existing home before closing on a new construction purchase, the builder typically agrees to a contingent sale provision. That provision has always included a deadline, a point by which the buyer’s existing home must be under contract so the builder can schedule closing with confidence.

For years, builders in Clark County handled those deadlines with flexibility. The resale market moved quickly enough that contingent buyers could list and reliably get under contract within a reasonable window. If timelines shifted slightly, builders often managed the adjustment without a formal charge.

That changed around the end of 2024. The resale market slowed, median days on market stretched across Clark County, and builders began carrying costs on homes months into construction.

“It used to be a sellers’ market, so if somebody listed their house, there wouldn’t be a big issue of it sitting and taking 90 days to sell. It was probably the end of 2024 that builders were getting caught having to push out close dates on homes because folks were not listing in a timely manner. Instead of taking a lackadaisical stance on ‘sure, you’ve got a contingent sale, no problem,’ no, it’s important that structures are in place. We’re at first floor framing; you need to get ready to list your house.” – Marci Caputo, Managing Broker / Co-Founder, New Construction Market Experts

The builders’ response became more formal. Flat fees appeared first, with some around $3,000 per extension period. Then, percentage-based fees tied to the purchase price followed, which made these terms more important for buyers to understand upfront.

The Real Cost of Contingent Sale Extension Fees in Clark County

During a recent community tour, Erin Smiley, one of our co-founders, found that these fees are increasing. Erin then surveyed builders across Southwest Washington to understand whether this was an isolated case or a trend.

“One builder had changed from a flat $3,000 fee to a 1.5% fee of the purchase price. So I surveyed builders in Southwest Washington and inquired, ‘Have you changed your policy?’ Probably two-thirds said ‘we take it on a case-by-case basis and talk about it in management.’ You’re always trying to balance, you don’t want to put a policy in place and then have the market change, and suddenly you’ve got a policy that’s too strict, and these folks are going to the competition.” – Erin Smiley, Buyer’s Agent and Co-Founder, New Construction Market Experts

That two-thirds figure is useful for buyers. It means the extension fee structure is often negotiable, but only if a buyer raises the conversation before signing.

Clark County’s Resale Timeline and the Risk Move-Up Buyers Are Carrying

The extension fee is only one part of the planning picture. The other part is timing, and the Clark County resale market in 2026 requires more preparation than it did two years ago.

The countywide median days on market for resale inventory as of March 2026 was approximately 76 days. For a move-up buyer trying to coordinate a sale closing with a build completion date, that number carries important planning implications.

A buyer who waits until their build is three months from close before listing an existing home may have limited time. The median days on market do not account for preparation time before listing, negotiation with buyers, or inspection contingency periods. It also doesn’t cover lender timelines on the purchase side. The math requires more runway than many buyers expect.

This coordination is exactly what a buyer advocate is for. The NCME team tracks milestones, aligns list-date planning with construction phases, and flags timeline points when a contingent seller should be preparing their existing home.

Smart Move-Up Buyers Ask These Questions Before Signing

Most buyers focus on the purchase price, the upgrade package, and the estimated closing date when they meet with a builder’s sales representative. The contingent sale provision deserves the same attention because it can affect your final cost and timeline.

Before signing any new construction contract in Clark County or Southwest Washington, get clear answers to these questions:

• What is the contingent sale deadline, and is it realistic? Compare the contract timeline to the current days on market for your neighborhood and price range. If the contract gives you 60 days and the market needs 76, the timeline may need more discussion.
• What are the exact terms for the extension fee? Ask whether the fee is flat or percentage-based, what the dollar amount is relative to your purchase price, and when it triggers. A percentage-based fee of 1.5% on a $700,000 purchase is $10,500 per extension period.
• Is the extension fee structure negotiable? Based on Erin’s survey, the answer for most Clark County builders is yes, with management approval. Ask before signing.
• Who is representing your interests in this conversation? The builder’s on-site sales representative works for the builder. They can explain the builder’s contract and process, but their fiduciary responsibility lies with the builder, not with you.

Understanding how builder incentives work and who they benefit is part of the preparation every move-up buyer needs before sitting down at that table. A buyer advocate’s job is to protect your timeline and flag the contract clauses that could affect your budget. That distinction matters.

The Consumer Financial Protection Bureau’s homebuyer resources offer useful background on the purchase financing side of these transactions. Understanding your financing structure is directly connected to how much contingent sale risk you can realistically carry.

Move-Up Buyer FAQs on Contingent Sale Extension Fees

What is a builder contingent sale extension fee in new construction?

A builder contingent sale extension fee is a charge a builder applies when a buyer’s existing home does not sell within the timeline specified in the new construction purchase contract. Builders use these fees to offset carrying costs on homes already under construction when closing dates get pushed back. Fees may range from flat amounts of a few thousand dollars to percentage-based charges tied to the purchase price.

How much are contingent sale extension fees in Clark County right now?

Fee structures vary significantly by builder. Some Clark County builders still charge flat fees of around $3,000. Others have moved to percentage-based fees, with at least one documented case of 1.5% of the purchase price, which equals roughly $10,000 on a $650,000 purchase. The structure is not standardized across the market and can change as builder policies evolve.

Are contingent sale extension fees negotiable with Clark County builders?

In many cases, yes. A survey of Southwest Washington builders conducted by NCME found that approximately two-thirds handle these situations on a case-by-case basis. Buyers who understand the contract and ask the right questions before signing may have room to negotiate.

How do I know if my home will sell in time to avoid an extension fee?

Review the contingent sale deadline in the builder contract and compare it with the current median days on market in your area. Clark County’s countywide median as of March 2026 was approximately 76 days. That figure does not include preparation time before listing or lender timelines on the purchase side. A buyer advocate can help you work backward from the builder’s estimated close date to identify a realistic list date.

Does the builder’s on-site agent represent me as a buyer?

No. The builder’s on-site sales representative works for the builder. They can explain the builder’s contract and process, but their fiduciary responsibility runs to the builder. A buyer’s agent represents your interests in the transaction, including reviewing contract terms like contingent sale provisions and extension fees before you sign.

Can I buy new construction in Clark County without selling my current home first?

Yes, if your financial profile supports carrying two mortgages through the build period, or if you qualify for bridge financing. Many move-up buyers do need sale proceeds to close the new construction purchase, which is when the contingent sale provision applies. A lender pre-approval conversation before you begin the builder search will clarify which path your financial situation supports.

What happens if my home takes longer than expected to sell?

If your existing home exceeds the contingent sale deadline in your builder contract, the extension fee provision may activate. Depending on the contract terms, you may owe a flat fee, a percentage-based charge, or need to negotiate a contract modification with the builder. Reviewing and discussing the contingent sale provision before signing helps you understand your options.

Should I list my existing home before or after signing a builder contract?

The answer depends on your specific build timeline and the stage of construction when you sign. In most Clark County new construction scenarios, a buyer advocate will help you map build milestones with resale-market timelines. Listing too early creates its own complications. Listing too late can expose you to an extension fee. That coordination is one of the core services a buyer advocate provides in a contingent sale situation.
