According to this RedFin data from 2019 -- which looked at normalized sale prices and Walk Scores above 50 -- it is about 23.5% or $77,668 for 16 major US metro areas. Again, this is 2019 data and so things may have changed a bit, especially with the whole COVID thing.
It also varies by metro area in this data set. The premium in Boston, for example, is almost 30%. Whereas the premium in Oakland is actually a slight discount (-1.3%). There are going to be local conditions that play a role.
But as a whole there is an economic trend here that makes intuitive sense to me. Though it's not just a question of how pricey your home is. You also need to consider your transportation costs, the value of your time, and the health benefits of living in an environment that promotes consistent and moderate activity.
When you factor all of these things, maybe "premium" isn't the right way to look at this.


As a follow-up to my recent post about the rise of the second home, here is a chart (via the WSJ) showing second home and investor mortgage applications as a share of all applications in the US. In February of this year (2021), second home and investment properties accounted for 14.1% of all applications. This is a record number going back to January 2010.
What's also interesting about this chart is that, but for COVID, it shows a general decline over the last decade. I'm not sure what the split is between vacation and investment properties, but can we conclude that pre-COVID Americans were becoming less interested or perhaps less able to own a second home? And could the reason be that instead of owning a second home, more people simply started relocating permanently?
There is also an obvious seasonality to these applications. Each of the above valleys tend to correspond to the spring and summer months. It's almost as if every fall/winter we start thinking to ourselves, "Right, winter. Let's look for a place somewhere else." Is it that, or are there other forces at work here?


Real estate brokerage firm Redfin recently did an analysis of "mortgage-rate lock data" taken from the analytics firm Optimal Blue. A mortgage-rate lock is an agreement between a lender and a borrower guaranteeing a particular interest rate for a particular period of time.
What's potentially interesting about this data is that (1) approximately 80% of mortgage-rate locks apparently result in an actual home purchase and (2) buyers must specify whether they're applying to secure a rate for a primary home, a second home, or an investment property. So there's a high degree of intent that goes along with these applications.
What Redfin found when they looked at the data is that the growth in demand for second homes is exceeding that of primary homes by quite a wide margin. They argue that this is largely a result of people now working remotely.
But this rise in demand -- at least according to the above data -- appears to have started in the second half of 2019. So I think a few more data points would be helpful in understanding what's really going on. Is what we're seeing more about acceleration than about causation? And what does this look like a year from now?
