Campbell real estate expert Tim McMullen shares how to find the hidden value in your home — and a free AI calculator that shows your property's maximum worth. $

It’s around 10pm one evening in early March and I get an email: "DocuSign: Signed."  We're in contract.

24 hours earlier, we had listed a $5M Eichler home in Los Altos.  1-Day-On-Market.  A neighborhood price per square foot record had been set.

The ink is barely dry and I'm already excited about what comes next — I'm launching McMullen Properties, my own firm right here in Silicon Valley.  After 10 years and ~$115M sold, it felt like the right time for something new.  Something that actually brings Campbell homeowners value.  It’s not just about representation — it’s about setting neighborhood sale records every time.

Here's what I believe: Clients don’t need the skillset of a 1990’s agent anymore.  They don't need a door opener or someone to search Zillow for them.  Clients need mastery and execution.  They need to move faster than the market they’re competing against to make (or save) the most money in the one transaction they’ll do this decade.

1. Tangible Value

The best agents don't just sell houses.  They see the $200K hiding inside a property — the ADU potential, the unpermitted square footage that can be legitimized, the $40K kitchen remodel that returns $120K.  That's always been the most valuable skillset. What's new is the access homeowners now have to the tools.

We created the Maximum Property Value Calculator.  You paste your property’s Zillow link into our app and our AI pulls comps from the MLS, finds the highest price per square foot in your area, and maps it against your lot's buildable potential.  The result is your Maximum Possible Value — a data-backed ceiling for what your property could be worth.  Free, instant, no sign-up required.

Campbell residents can now receive a detailed value assessment and roadmap to achieve that value (40-60 hours of work from a seasoned developer in the past) within 24 hours. Knowing how valuable an asset could be is the first step in any appraisal.

2. Proprietary Data

Being ahead of the game is the precursor to success in real estate.  If you see it on Zillow, it’s too late to get a good deal.  We’re focused on building the best database of real estate opportunities in Silicon Valley – which tends to lead to finding some unique and interesting off-market deals. 

3. Mastery of the Irreplaceable Skill: Getting Two People To Agree

Fear, ego, attachment, money.  Every deal comes down to two people who see the same house and the same number differently.  Reading the room, defusing tension, guiding both sides to yes — that's the one thing no algorithm replaces.  Ten years of negotiations is the foundation McMullen Properties is built on.  The AI handles the data.  The human handles the room.

This is why I'm excited.  Not because the old model is breaking — because the new one is so much better.

"Tim helped make my first home buying experience easy and straightforward, giving me good and honest advice on evaluating houses, making offers, negotiating, and generally being very responsive to questions or concerns that I had during the process."

“After meeting with a few real estate agents, we decided to choose Tim for our home purchase and we were not disappointed. Tim was always a text or a phone call away and provided us with everything we needed and more. He was with us every step of the way during the experience and we couldn’t have asked for a better agent. He is extremely knowledgable of the current market landscape and helped us negotiate for an offer below asking in the San Francisco market (amazing right?!). He is kind, friendly and will always have your best interest in mind when he is assisting in your home purchase. We wholeheartedly believe that if we had chosen another real estate agent to work with we might not have been able to purchase our home since Tim brings a bunch of intangible skills to the table that other agents simply do not possess. We would highly recommend Tim to our friends and family and we will not think twice about working with him again in the future.”

“My husband and I were the first time home buyers. We contacted Tim just couple of months after moving to San Francisco. Tim really helped us to learn about different neighbourhoods in SF. He showed us all the apartments that we wanted to visit even the ones that we could not afford. He is a good negotiator and we end of buying an apartment below the asked price.”

“I highly recommend Tim as a realtor to help sell your home! He comes with all the skills and contacts (contractors, stagers, designers, etc.) to make the process successful. He is a great listener and highly responsive. We could not have asked more from a realtor to help us selling our first home. Thanks Tim!”
