How We Rank Castro Valley Real Estate Agents
Our rankings are built from verified MLS transaction data, not advertising spend. For every agent we analyze more than fifteen performance signals, including sales volume in your city and zip code, recent and all-time transactions, days on market, negotiation results (how far above or below list price an agent's clients actually close), price-point fit, and verified reviews. The agents shown first are those whose verified results put them at the top of the Castro Valley market today.
Agents cannot pay for placement in these rankings. The underlying data refreshes as new closed transactions are reported, so rankings shift with real market performance.
Rankings reviewed by Kevin Stuteville, Licensed Florida Real Estate Broker (License BK3068131), Founder of EffectiveAgents.

Castro Valley Real Estate Agent FAQs
How were these Castro Valley real estate agents ranked?
Rankings are built from verified MLS transaction data. We analyze more than fifteen performance signals for every agent, including sales volume in your city and zip code, recent and all-time transactions, days on market, negotiation results, price-point fit, and verified reviews. Agents cannot pay for placement.
How many real estate agents are in Castro Valley?
Our data covers 889 real estate agents serving the Castro Valley area. The count represents agents with transaction activity recorded in our Castro Valley market data, not simply everyone holding a license.
What does the median sale price in Castro Valley mean for sellers?
Castro Valley's median sale price is $1,271,500 as of May 2026. Half of recent sales closed above that figure and half below. It is a useful baseline for understanding the market, but an experienced local agent will price your home against comparable recent sales in your neighborhood, not the citywide median.
Does it cost anything to use EffectiveAgents?
No. EffectiveAgents is free for home buyers and sellers, with no obligation to work with any agent we match you with.
Do agents pay to be ranked or featured?
No. Agents cannot pay for placement anywhere in these rankings. Positions are earned from verified transaction performance only.
What commission do Castro Valley realtors charge?
Commissions are negotiable and vary by agent, service level, and transaction. There is no set rate, and recent industry changes have made commission structures more flexible than ever. Discuss the structure directly with your agent before signing a listing or buyer agreement.
