How a Buyer Rebate Actually Works on a Marin Home Purchase

California allows buyer rebates, the terms go in your written buyer agreement, and the money shows up as a credit on your Closing Disclosure if your lender signs off. At 2.5% buyer-side pay with a third rebated, that's about $16,700 on a $2M house, $25,000 at $3M and $41,700 at $5M.

Almost everybody who asks me about a rebate has already done the math on a napkin. Price, times some commission number, and a check falls out of the sky at closing.

Close enough to be dangerous.

The real version has a lender in it, plus a piece of paper you sign before I unlock a single front door for you.

That paper came out of the big commission lawsuits, and like most things lawyers build it's longer than it needs to be. Since August 2024, buyers sign a written agreement with their agent before touring homes. That agreement is where compensation lives now. If a rebate is part of our deal it goes on that page in plain numbers. If somebody only promised it out loud over coffee in Mill Valley, it doesn't exist. I'd walk.

So, some numbers. Illustration only. Every deal gets its own written terms. I picked these percentages because the arithmetic is easy, and your actual split gets set in your own agreement.

Say you buy a $3,000,000 house in Mill Valley and buyer-side compensation is 2.5%. That's $75,000. If the agreement says a third of that comes back to you, your credit is $25,000. Same split at $2M is about $16,700, and at $5M it's about $41,700.

Real money. Enough to swallow a big chunk of your closing costs, or the roof your inspector is going to stand in the driveway and sigh about.

And now the lender wants a word, because lenders always want a word. The rebate lands as a credit on your closing statement and your lender has to sign off on it. On a conventional loan Fannie Mae limits what it calls interested party contributions based on how much you put down, up to 9% of the price at 75% loan-to-value or lower, 6% between 75 and 90, and 3% above 90. Most lenders count an agent credit against that limit. Jumbo lenders, which in Marin at these prices is basically everybody, write their own rules, and a few of them are real tightwads about it.

Credits go to closing costs and prepaids. Your down payment is off limits, usually.

If the credit comes out bigger than what it can legally be spent on, the usual fix is a small price adjustment, and you want that worked out with your lender in week one, because finding out three days before close that your credit got trimmed is miserable and I've watched grown adults go pale over it on a conference call.

Paying cash? Easy. No loan cap. Credit goes on the statement and we're done.

Where it shows up on paper. The credit should appear on your Closing Disclosure, which your lender has to get to you at least three business days before you sign, and on the escrow or title company's settlement statement. Look for it in both places. If it's missing from the Closing Disclosure, call me and your loan officer that same day, because fixing it after the loan funds is a much bigger headache.

Who pays what can vary. The seller may pay the buyer agent commission through the listing agent, or you may cover part of it under our agreement, and plenty of deals land somewhere in between. The rebate is figured on what my brokerage actually receives at close, which is one more reason to get the formula in writing.

Taxes. I get careful here. My understanding is the IRS has generally treated a buyer rebate as a reduction in what you paid for the house, so it lowers your cost basis, and hasn't treated it as income. I sell houses, though. Your CPA gets the final say, so call them before you spend it in your head.

If I were the one buying, I'd get the percentage or a flat dollar figure written down, plus a line saying it's paid as a credit at close. Make the agreement spell out what happens if the seller offers less buyer-side compensation than we expected, or nothing at all. And what happens if the lender caps it.

People skip that last one. Every time.

Please don't.

I've been at this 17 years and closed north of $250M, and I can't remember a single deal that went well because of the rebate. The good ones went well because we priced the house right and read the inspection reports like they owed us money. In Marin the real savings come out of the offer strategy, and out of knowing which streets near Corte Madera Creek take water in January. The rebate was gravy on top.

It works best for buyers who know roughly what they want and already have financing lined up, and still want somebody who'll fight like a raccoon over a trash can on price. If you'd rather see forty houses with a lot of hand-holding along the way, that's completely fine. Tell me up front and we'll set the deal up for that instead.

The short version of how I set this up is on my Bay Area buyer rebate page.

Buying in Marin or Sausalito this year, or down on the Peninsula? Send me your price range and how you're paying for it. I'll run the rebate on your actual number and send it back. No napkin.
