What should longtime homeowners do before selling a home they've owned for 30 or more years in Los Altos? Start with where you will live next and the questions for your CPA, then gather the home's records, check its permit history, sort belongings at your own pace, and decide how much to prepare the house only after you have seen what similar homes nearby sold for.

If you bought your Los Altos home in the 1980s or 1990s, a lot has changed around you. The house has held decades of birthdays, graduations, and ordinary Tuesday dinners. And the market you would sell into today works very differently from the one you bought in.
None of that means you have to hurry. Most longtime owners think about selling for years before they act. This guide lays out what to do first, in a calm order, so that when you decide, you decide with a clear picture.
This is general information, not legal or tax advice. Your CPA and your attorney are the right people for those questions, and this guide points to them where they matter.
Why does owning a home for 30+ years change how you sell it?
A home owned for three decades is not just older. It comes with a different set of questions than a home bought five years ago.
- The gain is usually large. A home bought decades ago for a small part of today's value can raise real tax questions. Only your CPA can answer them for your situation.
- The paper trail is long. Remodels, additions, roof jobs, and sewer work may go back 30 years, and some records live only in a kitchen drawer.
- The rules have changed. Building codes, disclosure forms, and buyer expectations are not what they were when you bought.
- The belongings are a lifetime. Clearing a home you have filled for decades takes the most time and the most feeling.
- The next home matters as much as this sale. Many longtime owners care less about the sale itself and more about knowing where they will go next.
What should you do first, before talking about price?
Price is usually the first thing people ask about. It is rarely the right first step. Here is the order that tends to make the whole process calmer.
1. Decide where you want to live next
Before anything else, picture your next chapter. Do you want to stay in Los Altos or nearby? Move closer to family? Choose a single-level home, a townhome, or a community with services?
Many longtime owners are not looking for less house. They are looking for an easier home: one level instead of two, a smaller garden, less to look after. Knowing the answer shapes everything else, including the timing of the sale and whether you buy before or after you sell.
2. Bring your questions to your CPA early
A long-held home almost always comes with tax questions, and they are worth asking a year before you list, not a month after you close. Bring your CPA questions such as:
- What records do you need from me about what we paid and what we improved over the years?
- How would selling this year compare with selling later, for our situation?
- If we buy another home, how would its property tax work?
- Should we involve our estate attorney or financial advisor before we decide?
Your CPA may ask for receipts for improvements you made over the years. That is one more reason to start the next step early.
3. Gather the home's records
Start a simple folder, paper or digital, and collect what you can find:
- The original purchase papers and any refinance documents
- Receipts and contracts for remodels, additions, roof, windows, foundation, and sewer work
- Building permits and final inspection sign-offs
- Warranties and manuals for major systems
- Any past inspection reports, including from when you bought
- Records of anything repaired after a leak, a storm, or an insurance claim
You will not find everything. That is normal. What you do find helps your CPA, helps your agent prepare disclosures, and gives buyers confidence.
4. Check the permit history
Over 30 years, many Los Altos homes have had a family room added, a garage converted, a kitchen opened up, or a bathroom moved. Some of that work was permitted, and some may not have been.
Your agent can help you request the home's permit history from the City of Los Altos building department and compare it with what is actually there. If something was done without a permit, it is better to know now. You and your agent can then decide, with the right professionals, whether to address it or disclose it. Finding out in the middle of escrow is far more stressful.
5. Learn what you will need to disclose
California sellers are generally required to tell buyers about known issues with the home. After 30 years, you know a great deal about your house: the corner of the basement that got wet in a heavy winter, the old tree roots near the sewer line, the room that never quite heated evenly.
Write those things down while you remember them. Your agent will walk you through the disclosure forms, and if a question goes beyond what an agent can answer, your attorney is the right person to ask.
6. Sort belongings at your own pace
This is often the hardest step, and the one that most needs time. Start long before you list. A few approaches that tend to help:
- Go one room at a time, starting with the rooms you use least.
- Invite family members to choose what they want to keep, with a clear date.
- Use estate sale companies, donation pickups, and senior move managers for the rest.
- Keep what you love for the next home, and measure it against that home's rooms first.
Nobody needs to clear a lifetime in a weekend. Six months of steady, gentle work is far easier than three frantic weeks.
7. Consider pre-listing inspections
A pre-listing home inspection and a pest inspection show you what a buyer will see, before a buyer sees it. For an older home, this often removes surprises later. Ask your agent which inspections make sense for your house, and when.
8. Decide how much to prepare the house
Once you know the home's condition, you can choose how far to go:
- Sell as-is. The least work. Buyers account for the updates in their offers.
- Light refresh. Paint, flooring repairs, garden cleanup, and a deep cleaning.
- Larger updates. Kitchens, bathrooms, or systems. More time, more cost, and more decisions.
There is no single right answer. The useful question is not "What would make the house nicer?" It is "What have similar Los Altos homes sold for in each condition?" An agent should show you that side by side.
9. Choose an agent who takes the time
The right agent for a 30-year home is someone who listens first, explains each step, and does not rush you toward a listing date. Ask how they will market the home, how often you will hear from them, and who you will actually be working with day to day.
What are the most common mistakes longtime owners make?
- Starting with the list price. Price matters, but the next home, the tax questions, and the records come first.
- Waiting too long to talk to the CPA. Some tax questions are easier to plan for a year ahead.
- Underestimating the clean-out. It almost always takes longer than expected.
- Renovating on instinct. A big project done without looking at nearby sales can cost time without adding value.
- Not knowing the permit history. Old unpermitted work found late can slow or complicate a sale.
- Choosing an agent only on the highest suggested price. A number that sounds good on day one can lead to a long time on the market.
- Feeling rushed by anyone. It is your home and your timeline.
What does this look like in real life?
For example (an illustration, not a specific client): A couple in their late seventies has lived in their two-story Los Altos home since 1989. Their son lives in Portland and their daughter lives in Shanghai. The stairs are getting harder, and the garden takes most of their weekends.
They start by deciding what they want next: a single-level home close to their friends, their doctors, and downtown Los Altos. They meet their CPA in the spring and bring a list of questions. Over the summer, they collect old permits and receipts and find the plans for the 1998 family room addition. Their agent requests the permit history from the city, and it matches.
Clearing the house takes most of the fall. Their daughter flies in for two weeks to choose the pieces she wants. An estate sale company handles the rest. Their agent shows them what similar nearby homes sold for as-is and after a light refresh, and they choose fresh paint, new carpet upstairs, and a garden cleanup.
Every update goes to both of them and to their son and daughter, in English, with a Chinese version for their daughter. Nobody feels rushed. When they are ready, they are truly ready.
How can a local advisor help a longtime owner?
Selling after 30 years is as much about people as about property. It helps to have someone who will sit at the kitchen table as many times as you need, explain each step plainly, and coordinate the inspectors, contractors, estate sale companies, and movers so you do not have to.
