Home buying and hedonic regressions

Here’s a fun game you can play if you are presently in the market for a home. One could consider a variety of home characteristics, but if you are in the market for a school district, the pricing lines should be very crisp. And you must be in the market for your own family. Speculating on what others will do just isn’t the same.

If you are not familiar with hedonic regressions, it is a mathematical process where given a set of data, which is subjected to an equation built with defining characteristics, the numbers reveal the various levels of importance of each feature. If we are looking at housing prices, the coefficient in front of the school district data will tell how much of the home price was dedicated to that selection.

But you don’t have to be a math geek with access to a bunch of data to come up with a result! I’d say any buyer who is seriously evaluating this choice can shoot from the hip (after looking, bidding and seeing the values the properties commanded at close). Ideally you want to be considering two school districts which both contain similar homes to choose from within their school boundaries– say a 90’s built two story with four bedrooms up and a nice yard for the kids.

Even non-number types of buyers will be able to discern the differences when their money is in play, or their abilities to access other ideal features. School districts can swing a home value price as much as 15%, so on a home of $450K, a $67K difference. That’s noticeable. And consistent opinions about districts, which affect a great number of buyers, filter out in the numbers.

Buyers do not need regression models to calculate the price of other features. The distance to job centers, for instance, or the premium for a prestigious neighborhood. People will pay to be closer to work in order to spend less time in the car. They will also pay for neighborhoods with corner restaurants, quaint historical business crossroads and neighbors with recognizable names. The numbers here are large enough so that no pointy pencil needs to scratch out a calculation.

But there are hundreds of neighborhood features which are priced out in the offer on a home. And many of these could be better understood with the help of a little math.
