Mortgage

Mortgage rates in the 21st century

Let’s compare two charts. “Your chart”, or a chart that might come virtually unedited from spreadsheet software versus the chart your boss told you not to worry about: Your chart is perfectly serviceable and for a quick exploration might be perfectly fine. However, why routinely generate such charts if you have the ability to make something a bit more dynamic? Being able to produce more interesting charts might not be necessary, but it also probably doesn’t hurt.

Comparing recent periods of mortgage rate increases

THIS MORNING I SAW AN INTERESTING CHART OVER ON BLOOMBERG. In this post they compared recent 10-year Treasury yield movements with the Taper Tantrum in 2013. The chart you can see here was an area chart with overlapping line plots. I thought it would be a fun exercise to remix a similar chart with R. Eventually it will look like this: Let’s make our remix and try out a few alternative plots.

Majestic mortgage rate plot

COME AND MAKE A MAJESTIC MORTGAGE RATE PLOT WITH ME. We’ll use R to plot a few visualizations of mortgage rates. I recently gave a number of talks about the economic outlook and housing. One point I like to make is that mortgage rates are low. I’ve shown this through a variety of visualizations. But one of my favorites looks like this: Let’s make it. Data We’ll plot mortgage rates using the Freddie Mac Primary Mortgage Market Survey.

Mortgage rates are low!

MORTGAGE RATES ARE LOW IN THE UNITED STATES. How low? Let’s take a look. We’ll use R to plot a few visualizations of mortgage rates. We’ll also try out some of the nice features in the tibbletime package that help when working with time series data. For more on using tibbletime see this post and this one on making animated plots. Since I was already called out for alleged chartcrimes, I’m going to go ahead and let loose here.

What time is it? Time for tibbletime!

WHAT TIME IS IT? TIME FOR TIBBLETIME! In this post, I’m going to take the tibbletime package out for a spin. Turns out this package is quite useful for things I tend to do. We’ll use the tibbletime package to write some R code to extend our ongoing analysis of trends in the U.S. mortgage market (see here for example). Davis Vaughan (on Twitter) one of the authors of the tibbletime package suggested I take a look:

Analyzing mortgage data with R

TIME FOR ANOTHER DATA WRANGLING AND VISUALIZATION EXTRAVAGANZA. This time we are going to work hard to turn some big data into little data. That is, we’re going to work hard to aggregate several million loan level records into useful summary graphics to tell us about the U.S. mortgage market in 2016. I’ve been working on a lot of different ways to visualize trends in the mortgage market (see here and here for examples).

Mortgage loan size distributions

I AM WORKING ON ADDING some more analysis around mortgage origination trends (see here for a high level summary). It’s on the way, but let me just leave a few graphs for you. These are updated versions of the same ones we made last year. These infographics show the distribution of mortgage loan amounts by state/county and metro area. For the beeswarm plots (see for example, Flowing Data) plots I have randomly sampled 2,000 loans from each state/metro area.

Mortgage origination trends

IT IS SEPTEMBER AND THAT MEANS it is data release season. One of the most important September data releases for me is the annual HMDA data release. These data provide the closest thing to a publicly-available comprehensive summary of U.S. mortgage market activity that we’ll get (for right now). The recently released data is for 2016 and provides a detailed view of mortgage market activity across the country. Let’s take a look.

Housing market update September 2017

THIS WEEK WAS BUSY, with a lot of data releases. Earlier this week we talked about housing starts, but there were a bunch of other key releases. Let’s review some of them here. We’ll just do a quick description of the data and then follow up with a static chart and an animated gif. Mortgage rates are still super low U.S. weekly average mortgage rates ticked up this week, but remain down from the start of the year.

Mortgage Rate Kandinsky

THINGS ARE ABOUT TO GET A BIT MORE ABSTRACT IN THIS SPACE. Today we make some Kandinsky-style images with R. This summer I was fortunate to spend some time at the Pompidou Centre in Paris. The Pompidou Centre houses the largest collection of modern art in Europe. I really enjoyed their collection of abstract and minimalist paintings. Well, turns out we can make our own abstract-style art using a Kandinsky R package from Giora Simchoni.

Of kernels and beeswarms: Comparing the distribution of house values to household income

BACK IN JANUARY WE LOOKED AT HOUSING microdata from the American Community Survey Public Microdata that we collected from IPUMS. Let’s pick back up and look at these data some more. Glad you could join us. Be sure to check out my earlier post for more discussion of the underlying data. Here we’ll pick up where we left off and make some more graphs using R. Just a quick reminder (read the earlier post for all the details), we have a dataset that includes household level observations for the 20 largest metro areas in the United States for 2010 and 2015 (latest data available).

Mortgage rates after dark

TONIGHT WE VISUALIZE MORTGAGE RATES AFTER DARK. Last year I shared 10 amazing ways to visualize mortgage rates (and more ways and even more ways). In this post I have one more DATA VISUALIZATION (dataviz) for you. I was putting together a presentation using remark.js via the xaringan R package (see my discussion of how to do this in this post) and decided to try a dark theme. The code below, modifies our mortgage rate code to make this graph:

Some animated gifs: Week of Oct 14, 2016

A couple of views of mortgage rates: Mortgage Rates in 2016 This chart shows the weekly average for the 30-year fixed rate morrtgage. Comparing mortgage rates by week This viz compares weekly mortgage rates (30-year fixed rate mortgage) by year. Each line represents a different year. The x-axis display the week of the year (from 1 to 52). Homeownership gif A homeownership rate viz. This shows the U.S. homeownership rate and breaks it out by the age of householder:

Distribution of mortgage loan amounts in 2015

IN THIS POST I WANT TO CREATE some data visualizations with R using the recently released Home Mortgage Disclosure Act (HMDA) data. For this post I’m going to return to the 2015 HMDA that you can get from the Consumer Financial Protection Bureau (CFPB) webpage and I discussed earlier. Check out my prior post for more discussion of how we build these data visualizations. R code for graphs posted below

Mortgage rates, some perspective

Another mortgage rates animated gif IN THE PAST I’ve told you how I made my mortgage rates gif. In this post I’m make an extension that uses stop motion techniques to reverse course. We’ll end up with this: For reference, here’s the standard gif I share each Thursday after mortgage rates come out: Stop motion animation While thinking about the week-to-week movements in rates it’s easy to lose longer-term perspective.

The week (so far) in charts

Mid-week chart update With existing home sales, house prices, and new home sales being released, this is one of the busiest weeks of the month for housing data. We’ll catch new home sales tomorrow morning, but let’s catch our breath and recap what we’ve learned so far this week. Existing home sales disappoint The National Association of Realtors (NAR) reported on existing home sales (EHS) on Monday. Existing home sales for February surprised most by dropping 7.

The week that was in charts

This past week I tracked several data releases that give us an idea of the health and vibrancy of the economy and housing markets. State employment trends positive Consistent with the national employment numbers state employment trends are positive. The BLS reported on employment trends by state for January 2016 this week. Eleven states plus DC had a statistically significant month-to-month increases in employment and five states experienced month-to-month declines.

How I make my mortgage rates gif

{% include JB/setup Making a data viz SOMETIMES ANIMATION CAN BE USEFUL, though it is often misused. I’ve been tracking the week-to-week changes in mortgage rates, and animating with a GIF. Example animated gif with mortgage rates from 1/1/2013 to 3/10/2016 I build my gif using the R statistical package. Perhaps I’ll explain more of the details later, but the R code below uses the ggplot2, ggthemes and animation packages to create the plots, style them, and save the animation.

The week ahead: housing starts and housing market index

{% include JB/setup The week ahead Next week there are several data releases but the two that I’m paying especially close attention to are the NAHB/Wells Fargo Housing Market Index (HMI) and Housing Starts, part of the New Residential Construction joint release by Census and HUD. Will builders maintain their sunny outlook? The HMI is a diffusion index based on survey questions about homebuilder’s attitudes. Values of the index above 50 indicate that on balance, more respondents feel positive than negative about the current conditions in and direction of the single-family housing market.
