Buying here is a contact sport. Listings move in days, you're often bidding against four other people, and most buyers sign contracts they haven't fully read. A buyer's agent works for you in that environment, which sounds obvious until you count how many buyers take advice at an open house from the seller's agent.
What it means
Your agent represents you legally and owes their duty to you, not the other side: analyzing properties, negotiating price and terms, reading contracts and disclosures with your interests in mind, and steering you through inspections and closing.
Why it matters more here
Inventory stays low and bidding wars are routine. Disclosure rules are strict, which helps you only if someone reads the packet properly. Condo HOAs vary wildly in financial health. Miss one and you find out later, usually expensively.
Keeping you from overpaying
In SoMa, the Mission, and Pacific Heights, homes sell over asking often enough that buyers stop questioning it. Your agent runs the comps and talks you down when you've fallen for a place and started reaching. Emotional overbidding is how good buyers end up upside down.
The parts that aren't price
Terms decide plenty. How you structure contingencies. What repair credits you push for. Whether an escalation clause helps or exposes you. What the seller actually wants, which is sometimes speed over the highest number.
Due diligence
San Francisco properties carry issues that never show up in listing photos. Seismic retrofit requirements depending on building type and era. HOA reserves that look fine until you read the financials. Permit history that doesn't match what's standing there.
Do buyers pay for their agent?
This changed in 2024. Buyers now sign a written representation agreement spelling out their agent's compensation before touring homes, and buyer agent pay is no longer advertised through the MLS. Sellers often still contribute, but it's negotiated per deal.
Representation shows its value in what you avoid: the retrofit bill nobody mentioned, the bid fifty thousand over what it needed to be, the missed deadline.
