Price per Square Inch for Pizza, Slices for Real Estate Market

Now that the Oscars are behind us and the “next big snowstorm” just missed NYC, I thought I would finally talk about pizza. But because of why you are here – I’ll make price per inch and price per square foot interchangeable.

One of my favorite podcasts, NPR Planet Money had a great segment called “74,476 Reasons You Should Always Get The Bigger Pizza

The math of why bigger pizzas are such a good deal is simple: A pizza is a circle, and the area of a circle increases with the square of the radius. So, for example, a 16-inch pizza is actually four times as big as an 8-inch pizza. And when you look at thousands of pizza prices from around the U.S., you see that you almost always get a much, much better deal when you buy a bigger pizza.

Explanation of above math: 200.1 inches of pizza surface versus 50.2 inches of pizza surface (pi*r squared=surface area of a circle) And here’s an easy way to calculate the volume of a pizza if you can’t help get enough pizza geometry.

Here’s the (pizza) logic
The premise of the piece is that it is much cheaper to buy a large pie than a small pie on a price per inch basis. Pricing for a large pie doesn’t expand as much as the surface area does so the price per inch drops precipitously. In the example above, the 16″ pizza wouldn’t be priced 4x as much as the 8″ pizza – probably more like 2x. Apparently pizza makers don’t take geometry seriously.

Buy the large and throw the unused portion in the fridge. Perhaps that is why people buy homes somewhat larger than what they actually need – they will grow into it.

Suburbs
In suburban real estate, after a certain point, larger the home is, generally the lower the price per square foot. There is a point of diminishing return on excess square footage. The total dollar price is higher, obviously, but the cost of additional space is usually less on a per square foot basis. Hence the pizza analogy applies.

Queen of Versailles, Florida
A well known example of diminishing return is the home featured in the documentary, Queen of Versailles. The 90,000 square foot home is so oversized for the Windmere, South Florida housing market that the vast majority of the living area likely has no value as a single family – other than to the current owners, of course.

Manhattan
In a market with one of the highest per capita population density for a US city, there is a premium for larger contiguous space so perhaps that is why we have so many pizza joints. Here is an price per square foot table by apartment size – you can see how ppsf expands with apartment size consistently over the decade (actually it has shown this pattern for the past 25 years). It’s expensive to get more living area in Manhattan.

“Appraising the appraisers” on National Public Radio

August 1, 2005 | 9:37 pm | | Public |

A few years ago, I decided to be more outspoken about the predicament that appraisers are in. We really don’t have a collective voice over the issue of the flawed structure that currently exists in our profession. It is essentially this:

Those who are paid on commission in the origination of a mortgage, determine which appraiser(s) to use. The system of checks and balances no longer exist.

Bob Moon of the Marketplace show on American Public Media radio showed great interest in the story. He researched and put together a broadcast aired on National Public Radio on June 23, 2005.

At about 6 minutes, it was one of the longest stories they had done in the past year. That meant either I was a fascinating interviewee or the story was compelling. (I assume the latter but was secretly hoping it was the former).

American Public Media “Market Place” Radio Broadcast Appraising the appraisers

UPDATE This was my first post on Matrix. The earlier posts were part of my original Soapbox Blog that I began in early July 18, 2005 and eventually merged into Matrix.

The Marketplace audio file link is broken so I don’t hope they mind me placing the audio file of the June 23, 2005 segment on my blog. This was the moment I came out on the situation appraisers were facing in public. If you’ve been following our industry or are part of it, the solutions set by Dodd-Frank have made the reliability of an appraisal done for a bank even worse.
