Most people who ask what their home is worth want one number. That is fair. But a valuation worth relying on is really an argument for a number, and the argument is the part that tells you whether to trust it.
Here is what actually goes into one.
Comparable sales are the spine of it
Everything starts with what similar homes nearby have recently sold for. Not what they were listed at. A list price is somebody’s opinion, sometimes a hopeful one. A closed sale is evidence — a buyer and a seller who both agreed, with a lender usually checking the math.
The best comparables are close by, recent, and genuinely similar in size and type. In a neighborhood like Bankers Hill or Mission Hills, where a block can change character quickly and the housing stock ranges from 1920s Spanish to new construction, “nearby” has to mean something tighter than a zip code.
Then come the adjustments
No two homes are identical, so every comparable needs adjusting up or down to account for the differences:
- Square footage, bedroom and bathroom count
- Lot size, usable outdoor space, and view
- Parking — which carries real weight in dense parts of the city
- Condition, age, and what has actually been updated
- Position within the neighborhood: the quiet side of the street is not the busy one
This is where judgment enters, and where two valuations of the same home can legitimately differ. Anyone who presents a valuation as a precise figure with no range is overstating what the method can do.
Condition matters more than people expect
Buyers are not appraisers. They respond to how a home feels in the first thirty seconds, and that response shows up in what they are willing to offer. A home that has been maintained and presented well will consistently outperform an identical one that has not.
What does not belong in the number
These come up in almost every conversation, and none of them change what a buyer will pay:
- What you paid for it. The market does not know or care about your basis.
- What you still owe. Your mortgage balance is a fact about your finances, not about the house.
- What you need to net to make your next purchase work. Real, important to plan around, and not a pricing input.
- An automated estimate. Those models read public records and past sales. They have never been inside. They cannot see that you redid the kitchen, or that the back bedroom has a moisture problem.
Automated estimates are a reasonable starting point for a stranger with no other information. You have better information than that.
Market conditions move the answer
The same house, on the same block, can be worth meaningfully different amounts depending on how much comparable inventory is competing with it, where rates sit, and how buyers are feeling that season. A valuation is a snapshot, not a permanent fact. If it is more than a few months old, it is history.
Why I would rather talk than just send a figure
A number by itself does not tell you what to do. What usually matters is the decision behind the question — whether to sell now or wait, whether a repair is worth making first, whether the move you are planning actually works financially. That conversation is the useful part, and the number falls out of it.
