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.
