The AI checks your answers before you download

14 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Verifies Purchase Price Calculation Integrity

This check ensures that the sum of all financial items in the 'Price and Terms' table (§4.1), including Earnest Money, New Loan, and Cash at Closing, precisely equals the total Purchase Price. This is critical for financial accuracy and to ensure the transaction is properly funded without discrepancies. A mismatch would cause closing calculations to fail and indicates a fundamental error in the contract's financial terms.

Ensures Logical Chronological Order of Deadlines

This validation verifies that the dates entered in the 'Dates and Deadlines' table (§3.1) follow a logical chronological sequence. For instance, the 'Record Title Deadline' must occur before the 'Record Title Objection Deadline', and all interim deadlines must precede the 'Closing Date'. This prevents impossible timelines, ensures the contract workflow is achievable, and avoids automatic defaults due to illogical scheduling.

Validates Completeness of Buyer and Seller Identification

This check confirms that the full legal names for both the Buyer (§2.1) and Seller (§2.3) have been entered. These fields are fundamental to the contract's validity as they identify the primary parties to the agreement. Failure to provide this information would render the contract unenforceable and legally void from the outset.

Ensures Complete and Valid Property Identification

This validation ensures that both the legal description and the full street address (Street, City, State, Zip) for the property are provided in §2.4. A complete and accurate property description is essential for a clear and unambiguous contract, preventing disputes over the subject of the sale. An incomplete address or missing legal description could invalidate the title transfer and the entire contract.

Validates Closing and Possession Date Sequence

This validation ensures the 'Possession Date' (§40) is on or after the 'Closing Date' (§39). A buyer cannot legally take possession of a property before the closing has been completed and title has been transferred. An invalid sequence would create a contractual impossibility and legal complications regarding liability, insurance, and property access.

Confirms Earnest Money Holder is Specified

This check ensures that the name of the 'Earnest Money Holder' is specified in §4.3. This is a critical fiduciary requirement to identify the neutral third party responsible for safeguarding the Earnest Money deposit. Without a designated holder, the funds are at risk, and the contract lacks a key component for managing the deposit and potential disputes.

Common Mistakes in Completing CBS1-8-24

The ones the AI is built to catch.

Using Street Address Instead of Full Legal Description

In §2.4, parties often enter only the street address, omitting the required legal description (e.g., lot, block, subdivision). This mistake happens because the legal description is not as readily available as the street address. An incomplete or incorrect legal description can create title transfer issues and, in worst-case scenarios, may render the contract unenforceable. To avoid this, the full legal description should be copied exactly from the seller's deed or a preliminary title report. AI-powered tools like Instafill.ai can help by cross-referencing property data to ensure the legal description is accurate and complete.

Ambiguity in Inclusions and Exclusions

Parties frequently fail to explicitly list all items they intend to include or exclude in §2.5 and §2.6, assuming items like smart home devices, custom window treatments, or high-end appliances are standard. This leads to major disputes during the final walk-through when a buyer finds an expected item removed. To prevent this, every item of value or significance that is not explicitly pre-listed should be written into the appropriate section. If the form is a non-fillable PDF, a tool like Instafill.ai can convert it into a fillable version, making it easier to add these crucial details.

Mishandling Leased Items and Encumbrances

Sellers often forget to disclose that items like solar panels, water softeners, or security systems are leased (§2.5.8) or have an outstanding loan (§2.5.5). This can result in the buyer unknowingly inheriting a lease or financial obligation, or the seller breaching the contract by being unable to convey the item free and clear. Sellers must meticulously list all such items and their status, and buyers must carefully review and approve the terms. Using a guided form-filling process can prompt users to consider and properly document these complex items.

Setting Unrealistic or Blank Contract Deadlines

The 'Dates and Deadlines' grid in §3.1 is the operational heart of the contract, yet parties often set unrealistic timelines or leave fields blank. Per §3.2, leaving a deadline blank deletes the entire corresponding clause, which could inadvertently waive a party's right to inspection or title review. Setting deadlines that are too short can force a party into default. All dates should be carefully calculated with input from lenders, inspectors, and title companies to ensure they are achievable.

Incorrectly Specifying How Title Will Be Held

In §2.1, buyers must select a form of tenancy, such as 'Joint Tenants' or 'Tenants In Common,' but often do so without understanding the significant legal and estate-planning consequences of their choice. This decision affects inheritance rights and how the property can be sold or refinanced. An incorrect selection can lead to complex legal issues in the event of a death or dispute between owners. Buyers should always consult with a legal or tax professional before making this selection.

Errors in the Purchase Price and Terms Calculation

The financial table in §4.1 requires that the sum of Earnest Money, New Loan, and other financing equals the total Purchase Price, with the 'Cash at Closing' amount being the final balancing figure. Simple arithmetic errors here are common and can cause significant problems with loan applications and closing disclosures. This can delay closing while the contract is amended and re-approved by the lender. Using a tool like Instafill.ai with built-in validation can prevent these calculation errors by automatically ensuring the table balances correctly.

Neglecting Water Rights and Well Information

In Colorado, water rights are a critical component of property value, yet the detailed sections in §2.7 are often overlooked or filled out incorrectly. Sellers may fail to provide the correct legal description for deeded water rights or the required Well Permit number. This can lead to the buyer not receiving the water access they anticipated or facing legal hurdles with the Division of Water Resources after closing. These sections require careful attention to detail and verification against official records.

Failing to Assign Responsibility for Closing Costs

Section 15 contains numerous checkboxes to allocate closing costs, association fees, and taxes between the buyer and seller. Parties often leave these blank, assuming a 'standard' practice exists, which leads to disputes at the closing table. Each fee, such as the 'Closing Services Fee' (§15.2) or 'Record Change Fee' (§15.3.2), must be explicitly assigned to avoid last-minute disagreements and potential closing delays. A thorough review of these sections during contract negotiation is essential.

Ignoring the Buyer Default Remedy Selection

Section 20.1 defaults to 'Liquidated Damages,' meaning the seller's sole remedy is to keep the earnest money if the buyer defaults. If a seller wishes to retain the right to sue for 'Specific Performance' (forcing the buyer to complete the purchase), they must check the box in §20.1.1. Many sellers are unaware of this choice and lose significant legal leverage by not actively selecting their preferred remedy during contract formation.

Incomplete or Inaccurate Party Names

Parties sometimes use nicknames or incomplete legal names in §2.1 (Buyer) and §2.3 (Seller). Title companies, lenders, and county recorders require full, accurate legal names that match government-issued identification and existing title documents. Using an incorrect name requires a contract amendment and can delay the entire transaction while documents are corrected and re-signed. AI-powered form fillers like Instafill.ai can help by storing and accurately populating full legal names across all necessary documents, reducing the risk of this type of data entry error.

What is the purpose of the 'Contract to Buy and Sell Real Estate (Residential)' form?

This form, approved by the Colorado Real Estate Commission, is a legally binding agreement between a buyer and a seller for the purchase of a residential property. It outlines all the terms, conditions, deadlines, and financial details of the transaction.

What is the difference between 'Inclusions' and 'Exclusions' in Section 2?

Inclusions are items that are included in the purchase price, such as lighting fixtures, built-in appliances, and window coverings, as specified in section 2.5. Exclusions are specific items that the seller will be taking with them and are not part of the sale, which must be explicitly listed in section 2.6.

What is the purpose of the 'Dates and Deadlines' table in Section 3?

This table is a critical part of the contract that lists all the specific deadlines for key events like loan application, title review, inspections, and appraisal. Missing any of these deadlines can have significant legal and financial consequences, as time is of the essence.

What happens to my Earnest Money if the contract is terminated?

If the buyer terminates the contract based on a right specified within the agreement (e.g., unsatisfactory inspection), the Earnest Money is typically returned to the buyer. If the buyer defaults, the seller may be entitled to keep the Earnest Money as liquidated damages, as detailed in sections 4.3 and 20.

What is a 'Seller Concession' and how can it be used?

A Seller Concession, detailed in section 4.2, is a dollar amount the seller agrees to credit to the buyer at closing. These funds can be used for various buyer expenses, such as closing costs, loan origination fees, or prepaid items, as long as the buyer's lender allows it.

What happens if the property appraises for less than the purchase price?

If the appraised value is less than the purchase price, the buyer has several options under Section 6. The buyer may terminate the contract, object and attempt to negotiate a lower price with the seller, or choose to proceed with the purchase by paying the difference in cash.

What are my options if I find something unsatisfactory during the property inspection?

According to section 10.3, if you find an unsatisfactory condition, you can either terminate the contract by the Inspection Termination Deadline or submit an Inspection Objection to the seller requesting repairs. If you and the seller cannot agree on a resolution by the Inspection Resolution Deadline, the contract will terminate.

I'm buying in an HOA. What are the 'Association Documents' the seller must provide?

The seller must provide you with the HOA's governing documents, financial documents, and insurance information by the Association Documents Deadline, as outlined in section 7.3. You have the right to review these and terminate the contract if you find anything unsatisfactory.

What are the consequences if the Buyer or Seller defaults on the contract?

If the buyer defaults, the seller may be entitled to keep the earnest money and potentially sue for other damages or specific performance. If the seller defaults, the buyer can cancel the contract and get their earnest money back, or sue for damages or to force the sale to go through, as described in Section 20.

The form advises consulting legal and tax counsel. Why is this important?

This contract has significant legal and tax implications, and real estate brokers cannot provide legal advice. Consulting an attorney or tax advisor is recommended to ensure you fully understand your rights, obligations, and the potential financial consequences of the transaction.

Can I use an AI tool to help me fill out this contract?

Yes, you can use AI-powered services to help complete this form accurately and efficiently. Tools like Instafill.ai use AI to auto-fill form fields, which can save time and reduce the chance of errors on complex documents like this.

The PDF version of this contract I have isn't fillable. What can I do?

If you have a non-fillable or 'flat' PDF, you can use a service like Instafill.ai to convert it into an interactive, fillable form. Simply upload the document, and the AI will automatically detect the fields, allowing you to fill it out on your computer.

What do I need to know about the 'Water Rights' section?

Section 2.7 addresses water rights, which can be complex and owned separately from the land itself. It's crucial to understand what rights, if any, are being transferred with the property and consult with legal counsel specializing in water law if this is a concern.
