Celebrating 10 years: fixed fees, full service, fast responses

Property search · The Consumer Protection Brokerage

Every listing shows your estimated rebate.

The green number on each home is what could come back to you: the buyer-broker fee (typically 2 to 3%) minus our flat $9,750. No other search shows you this, because no other brokerage gives it back.

This property offers investors the rare opportunity to purchase an investment asset in one of the most strategically connected locations in the San Francisco Peninsula.
