Can I Write My Own Offer on a House in California?

You found the home. You know what you want to pay. You're wondering: can I just write the offer myself and skip the agent altogether? The short answer is yes, legally you can. But the longer answer is that it's one of the riskier financial decisions you can make.

What "writing your own offer" actually means

In California, a purchase offer is made using the Residential Purchase Agreement (RPA), a standardized form published by the California Association of Realtors. It's a legally binding contract that covers price, financing terms, contingency timelines, deposit structures, inspection rights, closing dates, and dozens of other provisions that directly affect your legal rights and financial exposure.

You can technically fill out this form yourself or use a generic template. But listing agents are generally reluctant to work with unrepresented buyers because it creates more risk for everyone involved — including their seller.

What can go wrong

The California RPA is not a simple document. Incorrectly structured contingencies can mean you lose your earnest money deposit if you need to back out. Missed deadlines — even by a day — can waive your rights to cancel. Poorly worded repair requests can leave you liable for issues discovered after closing. And without someone reviewing the seller's disclosures with an expert eye, you might miss red flags that would have changed your decision entirely.

On a $900,000 purchase, your earnest money deposit is typically $27,000. That's the amount at risk if you make a contractual mistake. The cost of an agent to protect that deposit is a fraction of what you stand to lose.

The middle ground most buyers don't know about

The reason most buyers consider writing their own offer is cost. They found the home themselves — at an open house, online, or through their network — and paying 2.5% ($22,500 on a $900K home) for an agent who didn't help them find it feels unreasonable. And it is.

But the alternative isn't "write it yourself or pay full price." There are agents who specialize in the offer-and-close stage — they draft your offer, negotiate terms, manage inspections and escrow, and close the deal for 1% commission instead of 2.5%. You get the professional protection without the inflated cost.

The math works out clearly: 1% on $900,000 is $9,000 for expert representation that protects a $27,000 deposit and a $900,000 purchase. Writing it yourself saves that $9,000 but puts everything else at risk.

When it might make sense to go solo

If you're a licensed real estate professional yourself, or if you have extensive experience buying and selling property and understand every clause in the California RPA, writing your own offer may be reasonable. For everyone else — including experienced investors — having a licensed agent review and submit the offer is worth the cost, especially when that cost is 1%.
