Question: I have recently seen two properties from Open Door listed for less than what they paid for it. Is that common for them or are these outliers?
Answer:
What is Algorithm-based Real Estate?
Algorithm-based buying and selling, also known as iBuying (2019 article here for more details), is when large companies/investors use algorithms (e.g. Zestimates) to assess a home’s value, purchase it (cash), and then resell it for a (hopeful) profit. These are arms-length transactions using corporate-level strategies rather than local ones.
The idea is that there are enough homeowners who value the ease and flexibility offered by iBuyers (cash, quick closings, no showings, etc) over getting a higher price that there’s billions in business for these companies (Open Door is currently valued over $3B). The acquisition and resale values of homes are determined by algorithms that these companies believe give them a clear picture of local markets across the country and competitive advantage at scale.
Zillow lost about $1B over 3.5 years using their pricing algorithms and shut down their iBuying business last year (article here for more details). After Zillow shuttered their iBuying business, it left Open Door as the biggest player in the industry. What makes them different than Zillow is that iBuying is their core business; for Zillow it was a supplemental revenue stream that risked hurting their core business.
I think the business in fundamentally flawed for many reasons, one of them being the massive disadvantages iBuyers are at during shifting market conditions. In strong markets, sellers can achieve the same or similar terms from everyday buyers and iBuyers are competing with everyday buyers on a house they haven’t seen, in a market they don’t know. In a weakening market (like we’re in now), properties they bought months earlier may be worth the same or less than they are when they’re being resold, so profits are smaller and losses much more common.
The greater D.C. Metro area is a relatively small, unattractive market for iBuying for multiple reasons, one being our diverse housing stock makes it difficult to value/project using algorithms; areas with large scale tract housing tend to much more popular with iBuyers (and corporate buy and hold investors) because it’s much easier to calculate market values.
How It’s Going…
As noted earlier, Zillow exited the iBuying business after ~$1B in losses over 3.5 years, leaving Open Door (market cap $3B+) as the main players in this category. I was curious how Open Door’s business is performing in Northern Virginia so I dug into their data from this year.
I looked at all of Open Door’s currently active (88), currently under contract (29), and sold (35) properties in 2022 and found 152 properties. I was able to find Open Door’s purchase price on 112 of those properties via public records.
Of the 112 homes I found Open Door’s purchase price on, the total acquisition price for these properties was $63,464,400, for an average of $566,646 per property, ranging from $207,100 to $1,031,800. If we assume their average purchase price held for the 40 properties I couldn’t find an acquisition price for, we can estimate their total acquisition price for all 152 properties in this data set (Northern Virginia sold in 2022 or currently under contract or listed for sale) to be $86,130,257.
Based on the analysis below, I think they may end up losing $5M-$6M+ on these investments.
