The AI checks your answers before you download

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

Purchase Price Numeric and Written Consistency

This validation ensures that the numeric value entered for the purchase price (e.g., '$150,000.00') is identical to the amount written out in words (e.g., 'One hundred fifty thousand dollars'). This is a critical check because in legal documents, the written amount often governs in case of a discrepancy. Failure to match can create ambiguity, potentially voiding the offer or leading to legal disputes over the intended price.

Financial Breakdown Summation

This check verifies that the sum of the Initial Deposit, Increased Deposit, First Loan Amount, Second Loan Amount, and the Balance of Down Payment equals the total Purchase Price Offered. This is a fundamental accounting check to ensure the offer is financially coherent and all funds required for the purchase are accounted for. If the amounts do not sum correctly, the offer is mathematically flawed and cannot be executed.

Mutually Exclusive Close of Escrow Timeline

This validation ensures that only one method for determining the close of escrow date is selected. The form provides options for closing on a specific date or a certain number of days after acceptance. A user cannot select both. This is important for creating a clear, unambiguous deadline for the transaction to be completed, preventing disputes about the contract's closing timeline.

Logical Loan Contingency Status

This check validates the relationship between loan-related fields and the loan contingency status. If 'NO LOAN CONTINGENCY' or 'ALL CASH OFFER' is checked, then fields for loan amounts, rates, and points should be disabled or flagged if they contain data. This prevents the submission of a contradictory offer that claims to be non-contingent on financing while also specifying loan terms.

Agent Representation Exclusivity

This validation confirms that an agent's representation status is not contradictory. For example, a Listing Agent cannot be checked as representing 'the Seller exclusively' and 'both the Buyer and Seller' simultaneously. Correctly defining representation is a legal requirement with significant implications for an agent's duties. An invalid selection would misrepresent the legal relationship between the agent and the parties.

Conditional FHA/VA Notification Period

This check ensures that if the buyer's financing is marked as 'FHA' or 'VA', then the 'FHA/VA Notification Days' field must be populated with a valid number. FHA and VA loans have specific requirements and timelines for notifying the seller of lender-required repairs. Failure to define this period in the contract leaves a critical deadline ambiguous, potentially jeopardizing the transaction.

Common Mistakes in Completing RPA-CA

The ones the AI is built to catch.

Using Incomplete or Incorrect Buyer Names
Buyers often enter nicknames, initials, or incomplete versions of their names instead of their full legal names. This creates a mismatch with loan documents and title records, which can delay or even jeopardize the closing process. To avoid this, always use the full legal name as it appears on government-issued identification, as this is what will be required for title and lending. AI-powered form filling tools can help by storing and consistently applying the correct legal names across all documents.
Mismatched Purchase Price in Words and Numbers
A frequent error is a discrepancy between the purchase price entered as a numeric value (e.g., '$500,000') and the amount written out in words (e.g., 'Five Hundred Five Thousand Dollars'). In a legal dispute, the written-out amount often prevails, which could unintentionally alter the contract's core financial term. To prevent this, meticulously double-check that both entries are identical. Advanced form-filling tools like Instafill.ai can eliminate this error by automatically generating the written-out amount from the numeric input, ensuring they always match.
Ambiguous Close of Escrow Timeline
The form allows for closing escrow on a specific date OR a certain number of days after acceptance, but not both. A common mistake is to either fill in both options or leave the section entirely blank, creating confusion about the legally binding closing deadline. This ambiguity can lead to disputes and potential breach of contract if a party fails to perform by the intended, but unclarified, date. Always choose only one option and fill in the corresponding date or number of days.
Incomplete or Inaccurate Property Identification
Simply providing a street address without the correct Assessor's Parcel Number (APN) and county is a significant error. An incorrect or missing APN can mean the contract is technically for the wrong property, rendering it unenforceable and causing major issues for title insurance and escrow. Always verify the APN from an official source like a preliminary title report or county records before writing the offer. AI tools can help validate address components and ensure all required location fields are completed.
Accidentally Waiving Critical Contingencies
Buyers who require a loan sometimes mistakenly check the 'NO LOAN CONTINGENCY' box or fail to specify the correct contingency removal timeframe. This is a catastrophic error, as it removes the buyer's right to cancel the contract without penalty if they cannot secure financing, putting their initial deposit at risk. It is crucial to understand and correctly fill out the loan and appraisal contingency sections to protect your interests. If the form is a non-fillable PDF, Instafill.ai can convert it into an interactive version, making these critical checkboxes clearer and harder to miss.
Unclear Allocation of Closing Costs
Sections for allocating costs like escrow fees, title insurance, and transfer taxes are often left blank or have both 'Buyer' and 'Seller' checked for the same item. This failure to clearly assign financial responsibility leads to disputes during escrow, delaying the closing until an agreement is reached. To avoid this, ensure every cost listed in the agreement is explicitly assigned to either the Buyer, the Seller, or is noted as split per local custom or negotiation.
Conflicting Checkbox Selections
Throughout the form, there are sections with mutually exclusive options, such as selecting the party responsible for paying for an inspection. Users sometimes check multiple boxes in a single section (e.g., checking both 'Buyer shall pay' and 'Seller shall pay'). This creates a contradiction that voids that specific clause until it is clarified via an addendum, wasting time and creating unnecessary back-and-forth negotiation. Carefully read and select only one option per item.
Inconsistent or Ambiguous Deposit Instructions
Errors in the 'Initial Deposit' section, such as mismatched numeric and written amounts or failing to specify the delivery method and timeframe, are common. This can create disputes over whether the buyer has fulfilled their initial obligation, potentially giving the seller an opportunity to cancel the agreement. Ensure the deposit amount is consistent and that the checkboxes for delivery method (e.g., 'Electronic funds transfer') and timing (e.g., '3 business days after acceptance') are clearly and correctly marked.
Incorrectly Defining Agent Representation
The form requires a clear declaration of whether an agent represents the Buyer exclusively, the Seller exclusively, or both parties in a dual agency role. Incorrectly checking these boxes misrepresents the agent's legal duties and can lead to significant legal and ethical complications. Buyers and sellers should review this section carefully to confirm it accurately reflects their understanding of the agent's role in the transaction.
Missing Initials on Each Page
The bottom of each page includes boxes for the buyer's and seller's initials, which serve as acknowledgment that they have reviewed and accepted the terms on that page. Forgetting to initial a page can raise questions about whether all parties have seen and agreed to the entire contract, potentially weakening its enforceability. It is essential to initial every required spot on all pages of the final agreement. Using a digital signing platform or a tool that highlights required fields can help prevent this oversight.

How complex is RPA-CA to fill out?

What is the purpose of this form?
This is a California Residential Purchase Agreement, a legally binding contract used by a buyer to make an offer to purchase real estate from a seller. It outlines all the terms and conditions of the sale, including price, financing, and contingencies.
Who is responsible for filling out this form?
Typically, the buyer or their real estate agent fills out this form to create the initial offer. The seller then reviews the offer and can accept, reject, or counter it.
Why do I need to write the purchase price in both numbers and words?
This is a standard practice in legal and financial documents to prevent ambiguity or fraud. If there is a discrepancy between the two, the amount written in words is usually considered the legally binding one.
What's the difference between an initial deposit and an increased deposit?
The initial deposit is the amount you provide with your offer to show you are a serious buyer. An increased deposit is an additional amount you may agree to pay later in the process, often after removing certain contingencies.
What is a loan contingency and can I remove it?
A loan contingency makes the purchase conditional on you successfully obtaining the financing described in the agreement. You can choose to waive this by checking the 'NO LOAN CONTINGENCY' box, but this means you are obligated to purchase the property even if your loan is denied.
What is an appraisal contingency?
An appraisal contingency allows the buyer to back out of the contract if the property appraises for less than the purchase price. The form gives you options to set a deadline for removing this contingency or to waive it entirely.
I'm making an all-cash offer. What do I need to do?
If you check the 'ALL CASH OFFER' box, you must provide the seller with written verification of sufficient funds to close the transaction. You can attach this verification to the offer or deliver it within a specified number of days after acceptance.
How do we decide who pays for inspections and closing costs?
The costs for inspections, escrow fees, title insurance, and transfer taxes are all negotiable. The form has specific sections where the buyer and seller must agree on who pays for each item by checking the appropriate boxes.
What is a one-year home warranty plan?
A home warranty is a service contract that covers the repair or replacement of major home systems and appliances for a set period, typically one year. The form allows you to specify who pays for the plan, the provider, and any optional coverages like for a pool or air conditioner.
What happens if I don't deliver my deposit on time?
The agreement specifies a timeframe, usually a set number of business days after acceptance, for you to deliver the deposit. Failure to do so can put you in breach of contract, potentially allowing the seller to cancel the sale and keep your deposit.

Yes, services like Instafill.ai use AI to accurately auto-fill form fields from your data, which can save significant time and reduce errors on complex forms like this.
