Beyond the Citywide Average: How Local Insight Changes Neighborhood and Agent Decisions
When buyers and sellers search for a neighborhood or a local agent, the results often look the same: averages, review counts, and sales volume. But according to Mark van Ryswyk, CEO and Co-Founder of Catchouse, those numbers can miss the details that actually shape a purchase or a sale. In a written interview, he shared examples from agents on the platform to explain where conventional advice falls short.
When the usual advice does not fit
The standard approach treats a neighborhood as a single unit with one set of numbers. Mark said the real unit is often smaller. Kenneth Pang, a REALTOR® with SERHANT. on the San Francisco Peninsula, makes the case that there are "neighborhoods within the neighborhood," and the right intersection can be the difference between a home that is one of one and one of many.
That distinction changes how buyers approach a purchase and how sellers position a sale. Mark described a case where a client knew exactly where they wanted to live, searched for months, and found that the home they had in mind simply did not exist in that area. Kenneth told them so and walked them through other neighborhoods they had never considered, built around what they actually needed from a home. That is where they ended up buying.
Tetiana Redko, a REALTOR® with Vanguard Properties, breaks Oakland down the same way: hills versus flats, areas with easy BART access versus car-dependent ones, cooler pockets that get the Bay breeze versus warmer ones, and streets close to shops and cafes versus quieter residential areas where you will drive to dinner. None of that shows up in a single citywide number.
What the ranking pages leave out
Mark said the pages ranking for these searches are mostly aggregated data: averages, lists, review counts, sales volume. What they leave out is the local, practical detail that changes the real cost and experience of owning a home there.
Tetiana's guide for first-time buyers in Oakland is one example. Oakland requires point-of-sale inspections, and the sewer lateral and sidewalk may need to be repaired around the sale. She puts those costs at roughly $5,000 to $15,000 for the sewer lateral and $1,500 to $20,000 for the sidewalk. Because much of the housing stock is older, she also tells buyers to be ready for pest repair findings in the $20,000 to $40,000 range, and notes that purchases over $2M carry a city transfer tax of around 1.75%. That is the kind of thing a buyer needs before they make an offer, and it rarely appears on a ranking page.
The same gap exists for agents. A ranking page tells you how many reviews someone has. It does not show you what they actually know about a specific area. Mark said that is the gap Catchouse is built around: agents sharing their local insight in their own words, so people can see the expertise before they reach out.
What people decide too quickly
The most common mistake, Mark said, is trusting a single number from the internet.
Dominique Chaplin, an agent with Fast Real Estate in Alameda and Contra Costa counties, makes this point about schools. If schools matter to your purchase, she tells buyers to confirm the assigned schools for that specific address directly with the district, because assignments can change, then visit in person and review the state's public information. She is clear that she can help with sources and properties, but the decision is the buyer's to make.
Kenneth makes a similar point about price: what a home is listed at, what it feels like it is worth, and what you can actually buy it for are three different numbers. Price does not always equal value.
The other thing people decide too quickly is the agent. Often it is the first name that appears in a search, without checking whether that person has shown real knowledge of the specific areas being considered. Mark suggested a simple test: ask an agent to walk you through the practical tradeoffs of an area, including commute, terrain, costs, local inspection rules, and what is being built nearby. Then decide for yourself what matters.
Practical takeaways
- Look beyond citywide averages and ask about block-level differences, terrain, transit access, and microclimate.
- Request a breakdown of local transaction costs, including inspections, repairs, and transfer taxes, before making an offer.
- Verify school assignments for a specific address directly with the district rather than relying on a single rating.
- Treat list price, perceived value, and achievable purchase price as separate numbers.
- Evaluate an agent by asking them to explain the practical tradeoffs of the areas you are considering, not by review count alone.
