Editor’s note: Today’s Post is from our PhREI Network founder, Daniel Shin MD, at The Darwinian Doctor.
In classic “The Darwinian Doctor” fashion, Dr. Shin gives a detailed personal account of his finances and how he “lost” $1 million overnight….This is a great post that covers how to estimate your home value and the effect that your home value has on calculating net worth.
Today’s post goes over the 3 best ways to estimate your home value, and why some methods are more reliable than others.
Just a couple of months ago, I broke down our net worth in gory detail. I revealed that as a homeowner in Los Angeles, a significant portion of this net worth is tied up in our primary residence.
My next post went into the problems with net worth, and highlighted especially the problem with real estate property valuation.
Our net worth (October 2020)
As you can see, a large portion of our net worth is tied up in real estate. In the October update, just two months ago, about 65% of our net worth was comprised of real estate equity.
Even though we are growing a rental real estate empire, the investment properties are still not a huge portion of this equity. The main chunk of this value is associated with our primary home.
Breakdown of our real estate portfolio
In this chart, below, I estimated the value of our real estate portfolio mainly using Zillow valuations.
You can see that at the time of the post, Zillow estimated our primary home to be worth about $2.8 million. Therefore, our home comprised about $1.5 million, or a whopping 78%, of our real estate equity.
But is this really correct?
As I mentioned in my post, when I looked into the exact “comps” Zillow was using to generate their valuation, I felt their methodology was flawed. It was including comps from a very exclusive neighborhood a few miles away called Fremont Place. In densely packed Los Angeles, a few miles away might as well be a different country. This gated enclave is home to celebrities and the very rich with average home values that at least double that of my neighborhood.
So I wasn’t too surprised to see the algorithm correct itself about a month ago. I was surprised at how much this correction affected their estimate of my home’s value.
Here’s the graphical representation of Zillow’s estimate of our home value over time.
The change in the last month of 2020 represents a 35% drop in our home valuation, and a $1 million loss of net worth!
The three best ways to estimate the value of your home
So this begs the question, is this correct? How am I supposed to estimate the value of my home, anyway?
I think there are 3 options.
The 3 best ways to estimate your home value
- Sell your home
- Get an appraisal
- Use online home value estimators
Sell your home
I think selling your home is the best way by far to know the value of your home. At the end of the day, your home is only worth what someone else is willing to pay for it. The only way to know this is to let the market decide, and sell your home.
There are clearly times when this might yield an inaccurate valuation (like during a pandemic, or directly following a market crash). But in general, I feel the free market is the most efficient and truthful indication of your home’s value.
Get an appraisal
The second best way to find the value of your home is with an appraisal.
If you’ve ever bought or refinanced a home, you’ve dealt with an appraiser. These are licensed professionals who are trained to use all available information to value your home. For example, they’re supposed to take into account overall sales trends, neighborhood comparative sales, and an actual site visit to generate their appraisal of your home value.
The site visit (or visual inspection) is what sets this valuation method apart. Here is a small list of what an appraiser may take into account during the inspection:
- Curb appeal
- Proximity to desirable things
- State of repair
The danger of this method is that the quality of the appraisal is only as good as the quality of the appraiser. If you’re getting the appraisal through a bank, you won’t have any choice over who you get to appraise your home. And if they make wrong assumptions, their valuation decision may come out too conservative, or conversely, over-inflated.
An official appraisal can also be costly. This may run you anywhere from $200-600.
Online home value estimators
If you’re not planning to sell your home, and don’t want to pay for an official appraisal, you’re left with the third and worst option: online home value estimators.
The first and original example of this is Zillow. In many ways, it set the standard for this industry. It’s regarded by many as the best of the free options.
The obvious downside is that the algorithms powering these estimators are only as smart as their programming. They won’t take into account subtleties and are prone to errors.
The Zillow algorithm, for example, has no idea that we sunk about $175,000 into the creation of a nice 1 bedroom accessory dwelling unit in 2018, adding about 550 square feet of permitted living space to our land.
The good news is that there are now a number of popular real estate websites that have added a home value estimate to their functionality. So you don’t have to depend on just one estimate.
Our home’s average estimated value
If you just want to get a rough idea of your home’s value (for a blog post, for example), you can just average all the free estimates available.
Here’s our average value as of December 2020 from five free online tools:
Out of these 5 values, only the one from Chase changed when I updated the correct counts of bathrooms and square footage. It also seems the closest when I compared recent sales in the neighborhood.
Note: helpful readers let me know that Zillow and Trulia are the same company under different names. Keep this in mind when interpreting their information.
I hope this has been helpful in giving you some options to estimate your home value.
While I think the online estimator tools are useful, they’re prone to error and can’t take subtleties into account. And if you rely on just one, you might get a sudden shock when its algorithm drops your home value by 35% overnight.
If you really want to know your home value, go for an appraisal, but nothing replaces actually selling your home to know its worth on the free market.
Did I really lose $1 million of net worth overnight? I don’t think so. I’m hoping to have a better feel for this via the bank appraisal method as we try to refinance our mortgage next month.
I’ll let you know how it goes!

Update – I did end up getting a formal appraisal, and my suspicions were correct. The home is worth about $2.2 million. It’s a good lesson not to put too much value in the Zillow estimate!
2.2 is still pretty amazing
