If housing affordability is your main concern, here is what most headlines leave out: the equity you build as an owner quietly offsets a large portion of your monthly cost. When researchers at First American factored appreciation into a rent-versus-own comparison across the top 50 markets in the country, owning came out cheaper in every single one. The Los Altos market is no exception to that math.
You know how every article you read lately seems to be telling you that buying a home right now is out of reach? And then you look at your rent statement and wonder if staying put is actually the safer move? A lot of people weighing their options in Los Altos real estate are sitting in exactly that tension right now.
But here is the part most people have not stopped to think about yet: the headlines about housing affordability are not necessarily wrong. They are just incomplete. And the part they are leaving out could change the entire calculation for your situation.
What Does “If Housing Affordability” Actually Mean for You?
What does your housing situation look like right now? Are you renting month to month, watching your payment climb each renewal cycle? Or are you sitting on the sidelines, waiting for prices to drop before you make a move?
Here is a question worth sitting with: if housing costs are your primary concern, have you ever stopped to think about the difference between what a home costs you and what it gives back?
Most affordability conversations focus on the outflow, the mortgage payment, the down payment, the closing costs. Don’t forget that a mortgage payment is also building something. Rent builds nothing you keep.
For three decades, buyers across the country paid a significantly larger share of their income toward housing than today’s buyers do. Mortgage rates through the 1980s regularly exceeded 10 percent. Even with lower nominal home prices, the affordability picture was far more strained than today’s headlines suggest. When today’s buyers in Los Altos spend roughly 20 percent of their income on a mortgage payment, they are operating well inside the historical norm, not outside it.
The Number Most Buyers Never See in the Affordability Equation
Odeta Kushi, Deputy Chief Economist at First American, makes a point that reframes the entire conversation around if housing affordability. Her argument: rapid home price appreciation feels intimidating before you buy. Once you own, that same appreciation becomes an asset working in your favor.
To put real numbers to that idea, her team analyzed the rent-versus-own equation in major markets. They took a realistic mortgage payment, then subtracted the monthly equity benefit from appreciation. In many of the top 50 markets, the monthly equity gain exceeded the mortgage payment itself.
Can you see how that changes the picture? If you are paying $2,500 a month toward a mortgage, but the home is gaining $3,500 a month in equity, what is the actual net cost of owning?
After the housing crash bottomed out around 2011, the Silicon Valley market, including homes in Los Altos, began a steady upward climb. Buyers who entered the market during this window built substantial equity over the following decade. Those who waited for prices to correct further found themselves priced out by 2016 and 2017. The pattern is not unique to that era; it tends to repeat for buyers who let affordability concerns keep them permanently on the sidelines.
The Question Housing Affordability Headlines Don’t Ask You
Here is something worth considering. Most lenders use 28 percent of gross monthly income as their guideline for a mortgage payment, covering principal, interest, taxes, and insurance. Freddie Mac includes that benchmark in their homebuying budget guidance. Today’s buyers are averaging closer to 20 percent. That means the average buyer has room inside the guideline that is not being discussed.
So why does it still feel unaffordable to so many people? Part of it is comparison. Buyers who entered the market a year or two earlier got different terms. That feels unfair. But here is the question: how long are you willing to let someone else’s deal determine your timeline?
What happens if nothing changes in your situation over the next three to five years? If rents in your area keep climbing, and home values in Los Altos homes for sale continue to appreciate, where does waiting leave you?
Homeowners who purchased in Los Altos between 2019 and 2021 accumulated equity at a pace that would have been difficult to predict. Nationally, the average homeowner net worth has grown to nearly 40 times that of the average renter, according to data from the National Association of Realtors. In high-demand Silicon Valley submarkets, that gap is even wider. If housing appreciation continues at even a moderate pace, the compounding effect on owner net worth versus renter net worth becomes difficult to ignore.
Rent Versus Own: What the Full Math Actually Looks Like
When First American added equity accumulation into the rent-versus-own comparison across the top 50 markets in the country, owning came out less expensive in every single market. Not most of them. Every one.
That is not an opinion. That is the output of their analysis when the full financial picture is used, not just the mortgage payment in isolation.
Housing affordability conversations almost always focus on upfront costs and monthly outflow. Don’t forget the return side of that equation. A renter paying $3,500 per month ends the year with zero accumulated equity. An owner making a similar payment is building net worth with every statement.
Does that mean buying is the right move for everyone in every situation? No. Does it mean the affordability story you are reading in most headlines is the complete picture? Also no.
The question worth asking yourself is this: if you could lock in a monthly payment that never changed, and watch a portion of your net worth grow quietly in the background, what would that mean for where you are financially in ten years?
What This Means If You Are Weighing Your Options Now
Based on what buyers in the Los Altos market are working through right now, the conversation about if housing affordability is almost never just about the number on the listing. It is about understanding what each option actually costs when you account for everything, including what you build and what you give up.
If housing concerns have kept you on the sidelines, that is a completely understandable place to be. The data, though, suggests the calculation looks different once equity is part of the equation.
