Understanding New Construction Purchase Agreements Near Fort Sill: What Military Buyers Need to Know Before Signing

Buying a new construction home near Fort Sill is an exciting process. You get to choose your floor plan, pick your finishes, and watch your home take shape from foundation to final walkthrough. But before any of that happens, you will be asked to sign a purchase agreement. That document is the legal foundation of the entire transaction, and it looks very different from a standard resale contract.

How new construction contracts differ from resale contracts

If you have ever bought an existing home, you are familiar with the standard Oklahoma real estate purchase agreement. It is a form developed by the Oklahoma Real Estate Commission that balances the interests of buyers and sellers. Both parties use the same form, and its terms have been refined over decades of use.

A new construction purchase agreement is different. It is typically a builder-drafted contract written by the builder's legal team. Its primary purpose is to protect the builder, not the buyer. While reputable builders in the Lawton, Elgin, and Cache market produce fair contracts that still protect their interests, the agreement will almost always include terms that favor the builder more than a standard resale contract would favor a seller.

Key differences between new construction and resale contracts:

• The property does not exist yet. Instead of describing an existing home by its address and condition, the contract describes a home that will be built according to blueprints, a specifications sheet, and a list of selected finishes. The contract must account for the fact that the home you close on may differ slightly from the plans due to material availability, site conditions, and construction tolerances.
• The builder controls the timeline. Resale contracts close on a specific date agreed to by both parties. New construction contracts set an estimated completion date, but they almost never guarantee it. Builders include provisions that allow them to extend the closing date due to weather, material delays, permitting issues, and labor availability without penalty. In Southwest Oklahoma, summer thunderstorms and winter cold snaps can push timelines out by weeks.
• Material substitution clauses. Builders typically include language that allows them to substitute materials, fixtures, and finishes with comparable alternatives if the originally selected item becomes unavailable. This is common in today's market, where supply chain issues can delay construction. The contract should require the builder to notify you of substitutions and get your approval for significant changes.
• Builder addenda. Almost every new construction contract includes one or more addenda that modify the standard terms. These addenda can change how earnest money is handled, how disputes are resolved, what happens if the buyer backs out, and whether the buyer can conduct independent inspections. Reading the addenda is just as important as reading the main contract.
• Dispute resolution. Builder contracts often require mediation or binding arbitration rather than going to court. Arbitration can be faster and less expensive than litigation, but it also limits your ability to appeal a bad decision. If the contract requires arbitration, make sure you understand the process before you sign.

None of these differences mean you should avoid new construction. They mean you need to go into the process with your eyes open and with experienced representation on your side.

The key terms every buyer should understand

Before you sign a new construction purchase agreement near Fort Sill, make sure you understand these specific terms and how they apply to your situation.

Base price and included features. The base price is the starting price for the home as described in the standard specifications. It typically includes the basic finishes, standard appliances, and the builder's standard floor plan. Any upgrades, premium finishes, or structural changes will add to this base price through a separate selection sheet or change order process. Make sure the contract clearly states what is included at the base price and what costs extra.

Lot premium. If you are building in a community where lots vary in size, location, or views, the contract may include a lot premium. This is an additional cost added to the base price for choosing a specific lot. Corner lots, cul-de-sac lots, and lots with views of green space or the Wichita Mountains typically carry higher premiums. In communities near Medicine Park or Cache, lots with mountain views can command significant premiums.

Estimated completion date. The contract will include an estimated closing date or completion date. Read the language carefully. Most builder contracts say the date is an estimate only and that the builder is not liable for delays. Some contracts include a "time is of the essence" clause that works only in the builder's favor, meaning the buyer must close on time but the builder can delay without consequence. Look for language about what happens if the builder exceeds a reasonable delay threshold, such as 90 or 120 days past the estimated date.

Escalation and price adjustments. Some builder contracts include an escalation clause that allows the builder to increase the price if construction costs rise between the contract signing and the closing date. This is more common with custom builders than production builders. If your contract includes a price escalation clause, make sure it caps the maximum increase and specifies which cost categories can trigger it.

Builder remedies for buyer default. The contract will specify what happens if you fail to close on time or breach the agreement in another way. In a standard resale contract, the buyer typically forfeits their earnest money deposit. In a builder contract, the builder may also be entitled to additional damages, including the cost of carrying the home while it is listed for sale or the difference between the contract price and the price they eventually sell the home for. Make sure you understand exactly what you stand to lose if circumstances force you to back out.

Contingencies in new construction agreements

Contingencies are the conditions that must be met for the contract to remain binding. They protect you by giving you the right to walk away if certain things do not go as planned. In a resale contract, contingencies for financing, appraisal, inspection, and title review are standard. In a new construction contract, these contingencies may look different or may be limited by builder addenda.

Financing contingency. This contingency says your contract is contingent on obtaining a mortgage loan within a specified time frame. In new construction, the financing contingency period often starts from the date of the contract but may run longer than in a resale contract because closing is further in the future. Some builders in the Lawton and Elgin area require buyers to use a preferred lender in exchange for incentives or a reduced price. Using the builder's preferred lender can streamline the process, but you are not required to use them unless the contract specifically requires it. If you are using a VA loan, the builder and their preferred lender must be experienced with VA new construction financing. For a deeper look at the financing side, the new construction financing guide covers construction loans, VA loans, and builder incentive packages in detail.

Appraisal contingency. This protects you if the home appraises for less than the contract price. In a resale contract, this is standard. In some builder contracts, the appraisal contingency is limited or structured differently. The builder may agree to reduce the price to the appraised value, or they may require you to make up the difference in cash. With VA loans, the appraisal is tied to the property and cannot be waived. If your contract does not include an appraisal contingency, you could be required to close at the contract price even if the home appraises lower.

Inspection contingency. In a new construction contract, the inspection contingency typically covers your right to conduct inspections at specified stages of construction. Most builders allow a pre-drywall inspection and a final walkthrough inspection. The contract should specify when these inspections can happen, how much notice you need to give, and what happens if the inspector finds defects. The new construction walkthroughs guide explains what to look for at each stage.

Feasibility period. Some new construction contracts include a feasibility or due diligence period, typically lasting 7 to 14 days after signing. During this period, you can conduct inspections, review the builder's documents and HOA covenants, and decide whether to proceed. If you decide to cancel during the feasibility period, you get your earnest money back. Not all builder contracts include a feasibility period. If yours does not, ask whether one can be added. It is one of the strongest protections a buyer can have.

Title contingency. This protects you if there are title issues, such as liens, easements, or other encumbrances that affect the property. In new construction, title issues are less common because the builder owns the land and is developing it, but they can still arise. Make sure your contract includes a standard title contingency that gives you time to review the title commitment and object to any issues.

Deposits, earnest money, and down payment timing

New construction contracts handle deposits differently than resale contracts. Understanding these differences helps you plan your finances and protect your deposit.

Earnest money deposit. When you sign a new construction contract, the builder will require an earnest money deposit. The amount varies by builder and community but is typically 1% to 5% of the purchase price. In some communities near Fort Sill, the earnest money may be a flat amount, such as $5,000 or $10,000. This deposit shows the builder you are serious about the purchase.

Upgrade deposits. If you select upgrades that add to the base price, the builder may require a separate deposit for those upgrades at the time you select them. This is most common with structural changes, lot premiums, and significant finish upgrades. Read the contract to understand when upgrade deposits are due and whether they are refundable if the upgrade cannot be completed.

Down payment timing. In a new construction contract, your down payment is not due until closing, the same as in a resale transaction. However, because the closing date may be six to 12 months in the future, you have more time to gather your down payment funds. This can be an advantage for military families who need to time their PCS move with their home purchase. Use the extra time to ensure your funds are properly sourced and documented for your loan approval.

Deposit refundability. The contract will specify when your earnest money deposit becomes non-refundable. In most builder contracts, the deposit is refundable during a feasibility period (if one exists) and becomes non-refundable after that period expires or after certain milestones are reached, such as the start of construction. If you cancel after the deposit becomes non-refundable, you forfeit the deposit and may owe additional damages, as discussed above. Read this section of the contract carefully and make sure you are comfortable with the deposit refund schedule before you sign.

Builder addenda and what they change

The main purchase agreement is only part of the contract. Builder addenda are additional documents attached to the agreement that modify its terms. These addenda can significantly change your rights and obligations, so they deserve the same careful review as the main contract.

Common builder addenda near Fort Sill:

• Specifications addendum. This lists the exact materials, fixtures, and finishes included in the base price. It also describes the standard for each category, such as "builder-grade carpet" or "standard white appliances." Make sure you understand what is included and what is an upgrade before you sign. The specifications addendum is the document you will reference throughout the selection process.
• Change order addendum. This describes how changes to the plan or specifications will be handled after the contract is signed. It should specify that change orders must be in writing, signed by both parties, and include the cost of the change and any adjustment to the completion date. Without a clear change order process, verbal promises for upgraded finishes or structural changes may not be enforceable.
• Dispute resolution addendum. This may require mediation or binding arbitration instead of litigation. If the addendum names a specific arbitration organization, such as the American Arbitration Association, read the rules and understand the process. Arbitration can be faster and more private than court, but it also limits your ability to appeal.
• HOA addendum. If the home is in a community with a homeowners association, this addendum will outline the HOA covenants, conditions, and restrictions. It may also describe the association's assessment fees, architectural review process, and community rules. Read the HOA documents before you sign, not after. The HOA guide for military families covers what to look for in HOA documents near Fort Sill.
• Warranty addendum. This describes the builder warranty, including the structural, systems, and workmanship coverage periods and the process for filing claims. The warranty is a critical protection for new construction buyers. The new construction warranties guide covers what builders typically offer near Fort Sill.
• Design center addendum. If the builder has a design center where you select finishes, this addendum outlines the selection process, deadlines for making selections, and what happens if you miss a deadline. In some cases, missing a selection deadline means the builder chooses the standard option for you.

Do not sign any addendum without reading it thoroughly. If you do not understand a term, ask your agent to explain it. If the language is ambiguous or seems unfair, ask whether the builder will modify it. Builders who regularly work with military families near Fort Sill are often willing to make reasonable adjustments to their standard documents.

How VA loan requirements affect your purchase agreement

If you are using a VA loan to buy new construction near Fort Sill, your purchase agreement needs to accommodate several VA-specific requirements. These requirements protect you as a buyer and ensure the property meets VA standards, but they also affect the contract terms.

VA escape clause. The VA requires that every VA-financed purchase include a specific clause stating that if the property does not appraise for the contract price, the buyer is not obligated to proceed with the purchase. This is the VA escape clause. It overrides any builder contract language that might require you to make up the appraisal gap. Make sure your contract includes this clause verbatim as required by VA regulations.

Builder VA registration. The builder must be registered with the VA to build homes that can be financed with VA loans. Before you sign the contract, confirm that the builder is VA-registered. If they are not, you cannot use a VA loan to buy the home. Your lender can verify this during the pre-approval process.

VA warranty requirements. As covered in the new construction warranties guide, VA loans require a 1-year builder warranty and a 10-year structural warranty. Your purchase agreement should reflect that these warranties are provided. If the builder does not offer the required warranties, the VA will not approve the loan.

VA funding fee. The VA funding fee can be rolled into the loan amount, but it affects the total loan and the monthly payment. Your purchase agreement does not need to address the funding fee directly, but your lender will include it in the loan estimate. Make sure you understand how the funding fee affects your closing costs and monthly payment.

Allowances, selections, and change orders

One of the unique aspects of a new construction purchase agreement is that you do not buy a finished home. You buy a home that will be built according to a plan, and you have the opportunity to make selections that determine the final product. The contract governs how those selections are made and what happens when you change your mind.

Allowances. Some builders use allowances for categories like flooring, countertops, or lighting fixtures. An allowance is a set dollar amount included in the base price for that category. If you select items that cost more than the allowance, you pay the difference. If you select items that cost less, you typically do not receive a refund. Allowances are most common with semi-custom and custom builders. Production builders are more likely to include specific finishes in the base price rather than using allowances.

Selection deadlines. The contract will specify deadlines for making your selections. These deadlines are typically tied to the construction schedule. For example, flooring selections must be made before the drywall is installed so the flooring can be ordered in time. If you miss a deadline, the builder may choose the standard option for you, or they may charge a fee to expedite your selection. Make a calendar of all selection deadlines as soon as you sign the contract so you do not miss any.

Change orders. A change order is a formal modification to the contract that changes the scope of work, the materials, or the finishes. Change orders must be in writing and signed by both parties. They should include the cost of the change, any adjustment to the completion date, and a description of the work being changed. Verbal agreements with the builder or site supervisor are not enforceable as change orders. Always get it in writing.

Structural changes versus finish changes. Structural changes, such as moving a wall, adding a window, or changing the floor plan, are typically more expensive and take longer to execute than finish changes. They also require updated blueprints and may require a revised building permit. If you are considering a structural change, discuss it early in the process with your builder and your agent. Structural changes made after construction has started can be costly and may delay the completion date significantly.

For a detailed look at the selection process and how to make smart decisions about finishes and upgrades, the design selections and upgrades guide covers what military families should prioritize when choosing finishes near Fort Sill.

Closing timeline and delay provisions

The closing timeline is one of the most important terms in your new construction purchase agreement, especially for military families who are coordinating a PCS move to Fort Sill. If your home is not ready when you arrive, you need a place to stay. If your home is ready before you arrive, you need to close and carry two housing costs.

Estimated closing date. The contract will include an estimated closing date based on the builder's projected construction timeline. This date is almost never guaranteed. Builders in Southwest Oklahoma typically estimate 5 to 8 months for a production home and 8 to 12 months for a custom home, depending on complexity, size, and weather conditions.

Force majeure clauses. Builder contracts include force majeure clauses that allow them to delay closing without penalty due to events beyond their control. These include severe weather, material shortages, labor strikes, pandemics, and other unforeseen circumstances. In Southwest Oklahoma, summer storms, winter freezes, and periodic material supply chain issues can all trigger force majeure delays.

Buyer remedies for excessive delay. Some builder contracts include a provision that allows the buyer to cancel the contract if the delay exceeds a certain number of days beyond the estimated closing date, typically 90 or 120 days. If your contract includes this provision, make sure you understand how it works. You may be entitled to a full refund of your earnest money if you cancel due to excessive delay. If the contract does not include a buyer remedy for delay, your only option may be to wait or to negotiate a mutual release with the builder.

Coordinating with your PCS timeline. If you are timing your new construction purchase with a PCS move to Fort Sill, build buffer time into your plan. Plan for the home to be delayed by at least 30 to 60 days beyond the estimated completion date. Have a temporary housing backup plan, whether that means staying in TLF on post, renting a short-term apartment, or staying with family. The temporary lodging guide covers your options for short-term housing near Fort Sill while you wait for your home to be ready.

Why you need an agent to review your contract

One of the most common mistakes military families make when buying new construction near Fort Sill is signing the builder's purchase agreement without having their own agent review it first. The builder's on-site sales representative is a professional whose job is to sell homes. They are not your agent, they do not represent your interests, and they cannot give you advice about whether the contract terms are fair or favorable to you.

What your agent does in a new construction transaction:

• Reviews the contract and addenda. Your agent reads every page of the purchase agreement and the attached addenda, identifies terms that are unusual or unfavorable, and explains what each provision means for you.
• Negotiates on your behalf. If the contract includes terms that are too one-sided, your agent negotiates with the builder to modify them. This can include adding a feasibility period, adjusting the deposit refund schedule, including a PCS contingency, or clarifying the change order process.
• Coordinates inspections. Your agent schedules the pre-drywall inspection and final walkthrough with the builder, coordinates with your independent inspector, and ensures that inspection reports are shared with the builder in a timely manner.
• Manages the timeline. Your agent tracks the construction timeline, selection deadlines, and closing milestones so nothing falls through the cracks.
• Protects your deposit. Your agent ensures that your earnest money deposit is handled properly and is held in a trust account or escrow as required by Oklahoma law.
• Recommends local professionals. Your agent can recommend lenders who are experienced with VA loans and new construction, independent inspectors who know what to look for in a new home, and attorneys who can review the contract if needed.

If you have not already registered your agent with the builder, do it on your first visit to the model home. Builders track which agent introduced you to the community, and they typically require the agent to be registered before any negotiations begin. Register your agent before you discuss pricing or lot availability, not after. Registering after you have already started talking to the builder may result in the builder refusing to recognize your agent and thus refusing to pay a buyer's agent commission.

Moving forward with confidence

A new construction purchase agreement near Fort Sill is a complex document, but understanding its terms before you sign gives you the confidence to move forward with your building project. The contract governs everything from the base price and included features to the closing timeline and what happens if something goes wrong. Reading it carefully, understanding the addenda, and having your own agent review the terms are essential steps that protect your investment and your peace of mind.

For military families PCSing to Fort Sill, the new construction purchase agreement also needs to accommodate your unique timeline and financing needs. Whether you are using a VA loan, managing a PCS move, or selecting finishes from hundreds of miles away, the right contract terms make all the difference. If you are considering new construction in Lawton, Elgin, Cache, or one of the surrounding communities and want a clear explanation of what the builder's contract means before you sign, reach out to Travis. He can review the contract with you, explain the terms in plain language, and help you negotiate terms that protect your interests.

Your new home should be a source of excitement, not confusion. Understanding the purchase agreement is the first step toward making that excitement a reality.
